cationic polyacrylamide copolymers (pam): environmental half

cationic polyacrylamide copolymers (pam) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. concern has been expressed since little is known about the degradation of pam in soils.

How does flocculation work?
Flocculation is an efficient and cost-effective method for drinking water and wastewater treatment, and plays a major role in the fate of toxic contaminants in water; without sedimentation these dangerous particulates remain dissolved in the water . HOW THEY WORK By altering surface electrochemistry
What is coagulation flocculation?
The main purpose of coagulation and flocculation is to treat turbid (hazy or cloudy) water, thus improving water quality. This is especially key for wastewater treatment, and can reduce organic loads and suspended solids by up to 90%. Suspended solids are commonly found in the majority of surface water supplies and all wastewater supplies.
What types of flocculants are available for drinking-water applications?
We also offer NSF/ANSI Standard 60 compliant flocculants for drinking-water applications. Because the choice of flocculant can have a significant impact on chemical costs, performance, energy consumption and the environment, it is critical to work with a supplier who can also provide technical assistance.
Why do water treatment plants need coagulation flocculation?
Most water treatment plants rely on coagulation/flocculation to significantly improve water quality and save time and money in the process of producing treated water. Coagulation and flocculation are an essential first step in wastewater treatment, removing the particles that reduce the effectiveness of water disinfection.
