Wetlands are a cheap and easy way to clean water in small towns. But, most studies on these wetlands don't look at how they work when water flow changes throughout the day. This is important because water use in small towns isn't constant. In a recent study, three types of wetlands were tested. The
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
You know how sometimes wastewater has too much nitrogen but not enough oxygen-demanding stuff? That's a problem! One way we deal with this is using biological contact oxidation reactors (BCOR). These reactors use certain microorganisms to help remove the nitrogen. In this story, scientists found tha
Ever wondered how we can make sewage treatment more effective? Scientists have discovered that using tiny ceramic powder carriers in a special treatment bed can really make a difference. They tested this method on simulated sewage overflows, and the results were impressive. The ceramic powders, smal
