Polyethylene Terephthalate commonly known as PET or PETE is the mostly used polymer in the world. It is naturally transparent and semi-crystalline plastic used widely for products used in our day to day life. PET polymer is better termed as “Pol
Polyethylene terephthalate
Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). PET consists of polymerized units of the monomer ethylene terephthalate,
Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a reddish to yellowish-green gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including

- Can cationic polymers remove organic matter from drinking water?
- The removal of natural organic matter (NOM) from drinking water supplies can be achieved with cationic polymers, used here in jar tests on simulated waters made from concentrates of humic substances. In applying organic polymers to the removal of UV absorbing...
- Are cationic polyacrylamide copolymers used for sludge dewatering?
- Environmental Sciences Europe 30, Article number: 16 (2018) Cite this article Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land.
- Are cationic polymers a good flocculant for wastewater treatment?
- Cationic polymers are the most promising flocculants in the wastewater treatment sector because of a fast perception of particles by eliminating repulsive surface electrostatic forces, strengthening electrostatic interaction, and eventually producing effective adsorptions.
- Are cationic polyacrylamide copolymers bad for the environment?
- Cationic polyacrylamide copolymers (PAMs) 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 PAMs in soils.
