“Megatron. I do not mean to overstep, but when I was passing by the kitchen earlier I could not help but notice Rung struggling with the pump device again. Again, I do not want to be presumptuous, but he has been very agitated and, I think, upset with himself for being unable to meet Elegy’s fuel needs.”

Optimus, far more calmly than he feels, slides back the medical access panel at the side of his neck to expose his uplink ports.

“If you are comfortable with it, please share her current filtration specifications. And if you have one, a kickstart code for internal refinery activation. I will help.”

Megatron sends Optimus a sharp look.

Or- rather, he shoots it in Optimus' direction. It isn't actually aimed at Optimus. He knows.. he knows, of course, that Rung knows he can come to Megatron for anything, anything at all. But sometimes he won't, and that is.. it's not Megatron's fault, but it isn't Rung's fault, either.

Sometimes Rung struggles, to tell Megatron what he needs or wants, and sometimes Megatron isn't available for him to do so, so Rung won't bother him. He takes a moment, to vent, and the sharp look melts, a little.

It's no one's fault. He's not mad. But he is upset that Rung is upset.

He's also a little relieved. "Thank you, Optimus- yes, I'll share them." He unspools his own cable, and carefully, presses the jack into his port. Sends the code over to him.

And, meeting his optics, gives him a little smile. "She's as much yours as she is mine or Rungs."

A Sewage Treatment Plant (STP) is an essential infrastructure in modern urban development and industrial operations. STP Plant manufacturers in Delhi plays a vital role in managing wastewater, ensuring the environment is protected, and meeting legal regulations for water disposal and reuse. This article explains the basics of STPs, their importance, processes, and benefits.

What is an STP?

A Sewage Treatment Plant (STP) is a facility designed to treat and process wastewater generated by households, businesses, or industries. The main objective is to remove contaminants, making the water safe for reuse or discharge into the environment. 

STPs are widely used in various residential, commercial and industrial areas. STP Plant manufacturers in Delhi provide STP plants in residential complexes, commercial buildings, industries, and municipalities to minimize environmental pollution and conserve water resources.

Importance of STPs

1. Environmental Protection: Untreated sewage can cause water pollution and can be hazardous. Sewage water if not treated can pollute rivers, lakes, and groundwater, causing harm to ecosystems. STP plant offered by STP Plant manufacturers in Delhi (Hydraulic Aqua Engineers Pvt. Ltd.) ensures that only treated, non-toxic water is released into the environment.

2. Water Conservation: Water conservation is as important as living a healthy life. Treated water from STPs can be reused for purposes like irrigation, flushing, and cooling in industries, reducing water wastage.

4. Public Health: Proper sewage treatment reduces the risk of diseases caused by waterborne pathogens and creating healthy world to live in.

Let us understand how a STP plant works:

The sewage treatment process typically involves three stages:

1. Primary Treatment: This process removes large solids like plastics, rags, and organic debris. Settling tanks allow heavier particles to sink, while lighter materials float and are skimmed off.

2. Secondary Treatment: Biodegradation of organic matter using microorganisms in aeration tanks. At this stage common methods include activated sludge processes, trickling filters, and moving bed biofilm reactors (MBBR). 

3. Tertiary Treatment:  This stage involves advanced purification methods like filtration, disinfection (chlorination or UV treatment), and nutrient removal that helps removes not only impurities, chemicals but also germs and bacteria. This treatment ensures that the treated water is of high quality for reuse or discharge. 

There are wide areas where STP plants are to be installed and used. Following are some areas where these plants are used: 

Residential Areas: Various housing societies where there are number of flats and large amount of water is used requires STP plants for water treatment. Apartments, housing societies, and gated communities actually demands the sewage water treatment.

Commercial Buildings: Offices, malls, and hotels also need STP plant to treat sewage water in order to manage waste water and enhance water conservation.

 Industries: Various industries and factories, power plants, and refineries where huge water supply is required and that too in good quality require STP plants.

 Public Facilities: Most important of all are the public area like Airports, hospitals, and schools where water cleanliness is of high priority. These are the areas where large amount of quality water is required on everyday basis hence need some way to treat waste water.

Hence Sewage Treatment Plants provided by STP Plant manufacturers in india are critical for managing wastewater in an environmentally friendly and sustainable manner. By investing in efficient STP systems, we can protect water resources, promote public health, and ensure compliance with environmental regulations. Whether for residential, commercial, or industrial purposes, STPs play a pivotal role in shaping a greener future.

New filter captures and recycles aluminum from manufacturing waste

New Post has been published on https://sunalei.org/news/new-filter-captures-and-recycles-aluminum-from-manufacturing-waste/

New filter captures and recycles aluminum from manufacturing waste

Used in everything from soda cans and foil wrap to circuit boards and rocket boosters, aluminum is the second-most-produced metal in the world after steel. By the end of this decade, demand is projected to drive up aluminum production by 40 percent worldwide. This steep rise will magnify aluminum’s environmental impacts, including any pollutants that are released with its manufacturing waste.

MIT engineers have developed a new nanofiltration process to curb the hazardous waste generated from aluminum production. Nanofiltration could potentially be used to process the waste from an aluminum plant and retrieve any aluminum ions that would otherwise have escaped in the effluent stream. The captured aluminum could then be upcycled and added to the bulk of the produced aluminum, increasing yield while simultaneously reducing waste.

The researchers demonstrated the membrane’s performance in lab-scale experiments using a novel membrane to filter various solutions that were similar in content to the waste streams produced by aluminum plants. They found that the membrane selectively captured more than 99 percent of aluminum ions in these solutions.

If scaled up and implemented in existing production facilities, the membrane technology could reduce the amount of wasted aluminum and improve the environmental quality of the waste that plants generate.

“This membrane technology not only cuts down on hazardous waste but also enables a circular economy for aluminum by reducing the need for new mining,” says John Lienhard, the Abdul Latif Jameel Professor of Water in the Department of Mechanical Engineering, and director of the Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) at MIT. “This offers a promising solution to address environmental concerns while meeting the growing demand for aluminum.”

Lienhard and his colleagues report their results in a study appearing today in the journal ACS Sustainable Chemistry and Engineering. The study’s co-authors include MIT mechanical engineering undergraduates Trent Lee and Vinn Nguyen, and Zi Hao Foo SM ’21, PhD ’24, who is a postdoc at the University of California at Berkeley.

A recycling niche

Lienhard’s group at MIT develops membrane and filtration technologies for desalinating seawater and remediating various sources of wastewater. In looking for new areas to apply their work, the team found an unexplored opportunity in aluminum and, in particular, the wastewater generated from the metal’s production.

As part of aluminum’s production, metal-rich ore, called bauxite, is first mined from open pits, then put through a series of chemical reactions to separate the aluminum from the rest of the mined rock. These reactions ultimately produce aluminum oxide, in a powdery form called alumina. Much of this alumina is then shipped to refineries, where the powder is poured into electrolysis vats containing a molten mineral called cryolite. When a strong electric current is applied, cryolite breaks alumina’s chemical bonds, separating aluminum and oxygen atoms. The pure aluminum then settles in liquid form to the bottom of the vat, where it can be collected and cast into various forms.

Cryolite electrolyte acts as a solvent, facilitating the separation of alumina during the molten salt electrolysis process. Over time, the cryolite accumulates impurities such as sodium, lithium, and potassium ions — gradually reducing its effectiveness in dissolving alumina. At a certain point, the concentration of these impurities reaches a critical level, at which the electrolyte must be replaced with fresh cryolite to main process efficiency. The spent cryolite, a viscous sludge containing residual aluminum ions and impurities, is then transported away for disposal.   

“We learned that for a traditional aluminum plant, something like 2,800 tons of aluminum are wasted per year,” says lead author Trent Lee. “We were looking at ways that the industry can be more efficient, and we found cryolite waste hadn’t been well-researched in terms of recycling some of its waste products.”

A charged kick

In their new work, the researchers aimed to develop a membrane process to filter cryolite waste and recover aluminum ions that inevitably make it into the waste stream. Specifically, the team looked to capture aluminum while letting through all other ions, especially sodium, which builds up significantly in the cryolite over time.

The team reasoned that if they could selectively capture aluminum from cryolite waste, the aluminum could be poured back into the electrolysis vat without adding excessive sodium that would further slow the electrolysis process.

The researchers’ new design is an adaptation of membranes used in conventional water treatment plants. These membranes are typically made from a thin sheet of polymer material that is perforated by tiny, nanometer-scale pores, the size of which is tuned to let through specific ions and molecules.

The surface of conventional membranes carries a natural, negative charge. As a result, the membranes repel any ions that carry the same negative charge, while they attract positively charged ions to flow through.

In collaboration with the Japanese membrane company Nitto Denko, the MIT team sought to examine the efficacy of commercially available membranes that could filter through most positively charged ions in cryolite wastewater while repelling and capturing aluminum ions. However, aluminum ions also carry a positive charge, of +3, where sodium and the other cations carry a lesser positive charge of +1.

Motivated by the group’s recent work investigating membranes for recovering lithium from salt lakes and spent batteries, the team tested a novel Nitto Denko membrane with a thin, positively charged coating covering the membrane. The coating’s charge is just positive enough to strongly repel and retain aluminum while allowing less positively charged ions to flow through.

“The aluminum is the most positively charged of the ions, so most of it is kicked away from the membrane,” Foo explains.

The team tested the membrane’s performance by passing through solutions with various balances of ions, similar to what can be found in cryolite waste. They observed that the membrane consistently captured 99.5 percent of aluminum ions while allowing through sodium and the other cations. They also varied the pH of the solutions, and found the membrane maintained its performance even after sitting in highly acidic solution for several weeks.

“A lot of this cryolite waste stream comes at different levels of acidity,” Foo says. “And we found the membrane works really well, even within the harsh conditions that we would expect.”

The new experimental membrane is about the size of a playing card. To treat cryolite waste in an industrial-scale aluminum production plant, the researchers envision a scaled-up version of the membrane, similar to what is used in many desalination plants, where a long membrane is rolled up in a spiral configuration, through which water flows.

“This paper shows the viability of membranes for innovations in circular economies,” Lee says. “This membrane provides the dual benefit of upcycling aluminum while reducing hazardous waste.”

New filter captures and recycles aluminum from manufacturing waste

New Post has been published on https://thedigitalinsider.com/new-filter-captures-and-recycles-aluminum-from-manufacturing-waste/

New filter captures and recycles aluminum from manufacturing waste

Used in everything from soda cans and foil wrap to circuit boards and rocket boosters, aluminum is the second-most-produced metal in the world after steel. By the end of this decade, demand is projected to drive up aluminum production by 40 percent worldwide. This steep rise will magnify aluminum’s environmental impacts, including any pollutants that are released with its manufacturing waste.

MIT engineers have developed a new nanofiltration process to curb the hazardous waste generated from aluminum production. Nanofiltration could potentially be used to process the waste from an aluminum plant and retrieve any aluminum ions that would otherwise have escaped in the effluent stream. The captured aluminum could then be upcycled and added to the bulk of the produced aluminum, increasing yield while simultaneously reducing waste.

The researchers demonstrated the membrane’s performance in lab-scale experiments using a novel membrane to filter various solutions that were similar in content to the waste streams produced by aluminum plants. They found that the membrane selectively captured more than 99 percent of aluminum ions in these solutions.

If scaled up and implemented in existing production facilities, the membrane technology could reduce the amount of wasted aluminum and improve the environmental quality of the waste that plants generate.

“This membrane technology not only cuts down on hazardous waste but also enables a circular economy for aluminum by reducing the need for new mining,” says John Lienhard, the Abdul Latif Jameel Professor of Water in the Department of Mechanical Engineering, and director of the Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) at MIT. “This offers a promising solution to address environmental concerns while meeting the growing demand for aluminum.”

Lienhard and his colleagues report their results in a study appearing today in the journal ACS Sustainable Chemistry and Engineering. The study’s co-authors include MIT mechanical engineering undergraduates Trent Lee and Vinn Nguyen, and Zi Hao Foo SM ’21, PhD ’24, who is a postdoc at the University of California at Berkeley.

A recycling niche

Lienhard’s group at MIT develops membrane and filtration technologies for desalinating seawater and remediating various sources of wastewater. In looking for new areas to apply their work, the team found an unexplored opportunity in aluminum and, in particular, the wastewater generated from the metal’s production.

As part of aluminum’s production, metal-rich ore, called bauxite, is first mined from open pits, then put through a series of chemical reactions to separate the aluminum from the rest of the mined rock. These reactions ultimately produce aluminum oxide, in a powdery form called alumina. Much of this alumina is then shipped to refineries, where the powder is poured into electrolysis vats containing a molten mineral called cryolite. When a strong electric current is applied, cryolite breaks alumina’s chemical bonds, separating aluminum and oxygen atoms. The pure aluminum then settles in liquid form to the bottom of the vat, where it can be collected and cast into various forms.

Cryolite electrolyte acts as a solvent, facilitating the separation of alumina during the molten salt electrolysis process. Over time, the cryolite accumulates impurities such as sodium, lithium, and potassium ions — gradually reducing its effectiveness in dissolving alumina. At a certain point, the concentration of these impurities reaches a critical level, at which the electrolyte must be replaced with fresh cryolite to main process efficiency. The spent cryolite, a viscous sludge containing residual aluminum ions and impurities, is then transported away for disposal.   

“We learned that for a traditional aluminum plant, something like 2,800 tons of aluminum are wasted per year,” says lead author Trent Lee. “We were looking at ways that the industry can be more efficient, and we found cryolite waste hadn’t been well-researched in terms of recycling some of its waste products.”

A charged kick

In their new work, the researchers aimed to develop a membrane process to filter cryolite waste and recover aluminum ions that inevitably make it into the waste stream. Specifically, the team looked to capture aluminum while letting through all other ions, especially sodium, which builds up significantly in the cryolite over time.

The team reasoned that if they could selectively capture aluminum from cryolite waste, the aluminum could be poured back into the electrolysis vat without adding excessive sodium that would further slow the electrolysis process.

The researchers’ new design is an adaptation of membranes used in conventional water treatment plants. These membranes are typically made from a thin sheet of polymer material that is perforated by tiny, nanometer-scale pores, the size of which is tuned to let through specific ions and molecules.

The surface of conventional membranes carries a natural, negative charge. As a result, the membranes repel any ions that carry the same negative charge, while they attract positively charged ions to flow through.

In collaboration with the Japanese membrane company Nitto Denko, the MIT team sought to examine the efficacy of commercially available membranes that could filter through most positively charged ions in cryolite wastewater while repelling and capturing aluminum ions. However, aluminum ions also carry a positive charge, of +3, where sodium and the other cations carry a lesser positive charge of +1.

Motivated by the group’s recent work investigating membranes for recovering lithium from salt lakes and spent batteries, the team tested a novel Nitto Denko membrane with a thin, positively charged coating covering the membrane. The coating’s charge is just positive enough to strongly repel and retain aluminum while allowing less positively charged ions to flow through.

“The aluminum is the most positively charged of the ions, so most of it is kicked away from the membrane,” Foo explains.

The team tested the membrane’s performance by passing through solutions with various balances of ions, similar to what can be found in cryolite waste. They observed that the membrane consistently captured 99.5 percent of aluminum ions while allowing through sodium and the other cations. They also varied the pH of the solutions, and found the membrane maintained its performance even after sitting in highly acidic solution for several weeks.

“A lot of this cryolite waste stream comes at different levels of acidity,” Foo says. “And we found the membrane works really well, even within the harsh conditions that we would expect.”

The new experimental membrane is about the size of a playing card. To treat cryolite waste in an industrial-scale aluminum production plant, the researchers envision a scaled-up version of the membrane, similar to what is used in many desalination plants, where a long membrane is rolled up in a spiral configuration, through which water flows.

“This paper shows the viability of membranes for innovations in circular economies,” Lee says. “This membrane provides the dual benefit of upcycling aluminum while reducing hazardous waste.”

Ukrainian drones hit Russian missile arsenal, oil pumping station in Tver Oblast, SBU source claims

Ukrainian drones hit the Andreapol oil pumping station and missile arsenal in Russia’s Tver Oblast overnight on Jan. 29, a source in the Security Service of Ukraine (SBU) told the Kyiv Independent.

Drones operated by the SBU and the Special Operations Forces attacked the oil pumping station, which is part of the Baltic Pipeline System-2 operated by Russian state-owned oil pipeline company Transneft.

According to the source, the filtration pumping area and additive tanks at the station were damaged. The station is located around 750 kilometers (466 miles) north of Ukrainian border.

A spill of oil products and a fire were reported at the station.

“The Russians even had to shut down the main pipeline that supplies oil to the Ust-Luga terminal in Leningrad Oblast,” the source said.

Ukrainian drones also hit the 23rd missile arsenal of the Russian Defense Ministry in Tver Oblast. The depot and three buildings of the military unit came under the attack, the source claimed.

The Kyiv Independent could not verify these reports.

Earlier in the day, an intelligence source told the Kyiv Independent that multiple Ukrainian drones struck a Lukoil oil refinery in the Russian oblast of Nizhny Novgorod.

Kyiv considers oil refineries to be valid military targets, as profits from the fossil fuel industry fund Russia’s war machine.

Earlier this week, the Ryazan Oil Refinery in Russia suspended operations due to damage from Ukrainian drone attacks, Reuters reported, citing two industry sources.

‘Pure propaganda’ — Kharkiv Oblast governor denies Russian claims of capturing Dvorichna

Kharkiv Oblast Governor Oleh Syniehubov on Jan. 28 refuted the Russian Defense Ministry’s claims that Russian forces had captured the village of Dvorichna in the Kupiansk district, emphasizing that fighting in the area is ongoing, Ukrinform reported.
