flocculation performance of polyacrylamide

Characterization and Dimethyl Phthalate Flocculation. Flocculation is a usual step in water treatment and the flocculant is the core of flocculation technology, so it is very important to choose a suitable flocculant [17,18,19,20,21,22]. Consequently, priorities for flocculant and coagulation performance include high efficiency, low

GUIDELINES - European Commission

Dimethyl phthalate (DMP) and diethyl phthalate (DEP) are not used as plasticisers but e.g. as additives in cosmetics, medical devices, and household products. The interaction of phthalates with the polymers they are embedded in is weak, so they may be released from the plastic product into the environment and into the human body ...
