Flocculants are sometimes called coagulant aids and can be anionic, non-ionic, or cationic polymers. Frequently, anionic polyacrylamides with large molecular weights are used as a low cost coagulant aids. ...
The overall removal efficiency of COD reached 83.8% when the dilution ratio of raw wastewater was 1:2, the pH was 4 and the FeCl3 loading was 1,000 mg/L in the coagulation process; the dosage of H2O2 (30%,v/v) was 0.6% (v/v) and added in three steps, the n(H2O2)/n(Fe2+) was 2:1, n(Fe2+)/n(C2O42−) was 3:1 and the pH was 4 in the UV/H2O2/ferrioxalate complexes process; the pH was adjusted to 8.5-9 ...

The optimum conditions in coagulation process: pH, cationic polyacrylamide dosage, mixing speed and time is 4.3, 2 mg/L, 150 rpm and 30 s, respectively. ...
In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated. ...
The particle settling was enhanced by adding polyaluminum chloride (PAC) as coagulant and hydrolyzed polyacryamide (HPAM) or cationic polyacrylamide (CPAM) as flocculant. At optimal dose, the particle settling ability with PAC and CPAM was better than that with PAC and HPAM. ...
The chemical structure, morphology, hydrophilicity, molecular weight cut-off and antifouling properties of membranes were characterized using energy-dispersive X-ray spectroscopy, scanning electron microscopy, contact angle, polyethylene glycol tracers, and cationic polyacrylamide (C-PAM) filtration, respectively. The optimized self-assembled membrane was shown ...
The GEM System (advanced in situ flocculation - flotation described later in the text) was able to remove between 3,000 and 11,000 mg/l of MLSS at HRT of 5 GPM/ft2 . Cationic high molecular weight high charge (55%) granular polyacrylamide flocculant C- 498 HMW from KEMIRA (available in GRAS form) had to be used for the best clarification and sludge thickness ...
By utilizing the GEM System Dual 300/750, the system can adapt to increasing flows as the facility expands. By using a cationic polyamine coagulant to satisfy a portion of the positive charge requirement rather than using 100% of the cationic polyacrylamide, the site was able to reduce ongoing chemical costs to satisfy the positive charge ...
This study presents the results of a laboratory experiment which investigates the use of cationic polyacrylamide copolymers (CPAMs) as primary coagulants in the purification of solutions containing humic acids (HA). ...

Water soluble hydrophobically associated polyelectrolytes were copolymerised with dimethyl- [2-(2-methyl-acryloyloxy)-ethyl]-alkyl ammonium bromide (alkyl: propyl, hexyl, dodecyl) (DEACn) and acrylamide (AM) in inverse emulsion. Cationic hydrophobically modified polyacrylamides having different molecule weight and cationic degree were obtained by ...
