How to prepare flocculant of cationic polyacrylamide PAMC?

Raw materials Flocculant of cationic polyacrylamide PAMC was prepared in our laboratory through low-pressure ultraviolet initiation by copolymerization of acrylamide and [2- (methacryloyloxy) ethyl] trimethyl ammonium chloride.

Is polyacrylamide absorbed in kaolin particles and long chain flocculants?

Previous research suggested that polyacrylamide played an critical role in bridging of kaolin particles and long chain flocculants. Thus, we assumed partial HA was absorbed in kaolin particles, and was separated from water with kaolin particles by using PAMC.

Why is cationic polyacrylamide required to precipitate micro suspending particles?

3. The micro suspending particles in the water can not be removed completely by the polyaluminium chloride (PAC), therefore the Cationic Polyacrylamide is required to be used to precipitate the fine suspending particles.

Which flocculant is best for ha separation?

The researchers found that the flocculants with strongly cationic branch chains have much better flocculation performance than traditional coagulants of polyaluminum chloride (PAC). Chitosan-based flocculant was also developed for HA separation .

What types of water flocculants are used in domestic sewage treatment?

In the treatment of the domestic sewage, there are two types of the water flocculants: the PAM ( Polyacrylamide) and the PAC (Polyaluminium Chloride). The domestic sewage is the waste water which is directly discharged by the residents in the daily life, the major component is the stool and the washing waste water.

Does kaolin affect flocculation performance in ha water treatment?

Flocculation performance of synthesized PAMC was evaluated in HA water treatment. The synergistic effect of kaolin particles on HA flocculation was investigated. Fluorescence spectra of supernatant after flocculation were analyzed at various dosages. FTIR spectra and fractal dimension of flocs after flocculation were measured.
