How Water Treatment Plants Make Water Safe
Public drinking water systems use different water treatment methods to provide their communities with safe drinking water. Public water systems typically use a series of water treatment steps, including coagulation, flocculation, sedimentation, filtration and disinfection. 4 Steps of Community Wa...Read more -
How can silicone defoamer improve wastewater treatment efficiency?
In the aeration tank, because the air is bulged from the inside of the aeration tank, and the microorganisms in the activated sludge will generate gas in the process of decomposing the organic matter, so a large amount of foam will be generated inside and on the surface ...Read more -
Mistakes in the selection of flocculant PAM, how many you have stepped on?
Polyacrylamide is a water-soluble linear polymer formed by free radical polymerization of acrylamide monomers. At the same time, hydrolyzed polyacrylamide is also a polymer water treatment flocculant, which can absorb ...Read more -
