Comparison of Various Commercially Available Polyaluminium Chlorides (PAC)reated, some with flocculation agents. Because many different flocculants are commercially available, some of them made by Akzo, we investigated the composition of several polyaluminium chloride (PAC) flocculants and tried to relate this to their effectiveness in water treatment.

Chemical Dosing Control — Physical and Chemical Boundary ConditionsDosing chemicals means starting the intended reaction. If, for instance, phosphate removing processes are aimed for, then the addition of reaction partners, usually in the form of metal salts leads immediately and spontaneously to the formation of (solid) metal phosphate.

The Janus Face of Participatory Projects,n, and (3) separation. The efficiency of the coagulation/precipitation stage depends on many parameters including the raw water quality, the chemistry of the coagulant, physical parameters of the process, and the expected quality of the treated water according to the needs. An adequate understanding

Suggestions for further research,lation kinetics, floc size, floc strength, floc structure and reflocculation in the same experiment. The flocculation was of the equilibrium type and the differences in floc properties could be directly related to different characteristics of the cationic polyelectrolytes..With low charge density po

Suggestions for further research, of raw water. For a ratio of substitution of the aromatic ring by an alkyl ammonium group higher than 35%, the linear polymers are water soluble and flocculate the silica suspensions according to a classical charge neutralization mechanism. The corresponding cross-linked species are very swellable
