Nanoparticles, tiny pollutants, are a big worry. They can harm nature and people over time. A recent study looked at how these nanoparticles stick to and come off of aerobic granular sludge (AGS) in wastewater treatment. AGS is a special kind of sludge used to clean water. The study found that the
Wheat straw, often seen as farm waste, has a new role in cleaning up water. Scientists have found a way to tweak it chemically to soak up a harmful dye called Rhodamine B. This dye is tough to break down and can be toxic. The modified straw, now called EWS, is a game-changer. EWS is made by treatin
Scientists have found a way to make better filters for cleaning water. They used a common chemical found in oil called thiophene. This chemical was used to make a special kind of membrane. This membrane is like a super-fine sieve that can filter out tiny bits of dye from water. The best part? They m
Food scraps can be turned into useful stuff, like vinegar, through a process called acidogenic fermentation. This vinegar, or acetic acid, is great for cleaning up dirty water by helping to remove harmful nitrates. But, the problem is that the amount and type of vinegar produced can change a lot, ma
A big plant that cleans water, called an aerobic granular sludge (AGS) plant, is really good at taking out nutrients and organic stuff. But what about tiny pollutants, like medicine and chemicals? That's what scientists wanted to find out. They looked at 19 medicines and 2 industrial chemicals in th
In small towns across China, wastewater treatment plants are having a tough time. These plants use special ponds called ecological combination ponds (ECPs) to clean water. But when the water coming in changes a lot, it's hard to adjust the settings. This leads to too much air being pumped in and too
Wastewater treatment creates a lot of sludge. This sludge is a big problem because it carries antibiotic resistance genes (ARGs). These genes can spread and cause serious health issues. So, finding a way to break down sludge and get rid of these genes is crucial. One interesting approach is usin
Wastewater treatment faces a big hurdle in cold climates. The cold slows down the bacteria that break down ammonia. This makes it hard to clean wastewater effectively. But there's a clever fix: embedding immobilization technology (EIT). This method wraps the bacteria in a protective layer. It helps
Wastewater laced with phenol is a serious problem. It's tough to clean up using old-school methods. So, scientists decided to test out a new approach. They used a mix of sponge iron and activated carbon in a special reactor. This combo, called Fe&G, showed some impressive results. First off, Fe
Ciprofloxacin, a common antibiotic, is often found in waterways. This can lead to antibiotic-resistant bacteria and harm both people and the environment. Scientists have been working on ways to remove ciprofloxacin from wastewater using advanced oxidation processes. One method is anodic oxidation,
