Analysis of poly aluminum chloride flocculant

Poly Aluminium Chloride for your analysis of two wastewater treatment flocculant contrast.

Anionic aqueous dispersion of ionic surfactants suitable for a slurry with a positive charge, poly aluminum chloride as a settling agent can be effectively used to promote the steel, paper, and gravel washing wastewater treatment, coal and other mineral sedimentation of suspended solids liquid separation. In the PH value is neutral to alkaline wastewater treatment, the sedimentation rate and floc size and other indicators were higher than the powder type and emulsion type products.

Molecular cationic flocculant engage biotechnology, water and other sludge containing organic substances, although to form larger flocs, but remaining within the floc anionic group retains its hydrophilic properties, the impact dewatered cake moisture, cloth peeling resistance, adhesion and the like cake. Polymerization with a polymeric aluminum or iron, an inorganic polymer coagulant before dehydration treatment, the surface of the metal ions and sludge anionic hydrophilic group is bonded, so that the sludge has a hydrophobic surface. Add amphoteric polymeric flocculant, the anionic and cationic groups, respectively, and the surface of the metal ions and ions of sludge anion binding surface, such that the cake within the anionic groups are neutralized to improve the releasability of moisture content and other properties cloth , form a solid cake. The following table lists the water-dispersible amphoteric flocculant and cationic flocculants in wastewater sludge handling food in the experimental results. Indicates that the estimated effects of dehydration sexes than cationic flocculant, and combined use with inorganic coagulant treatment process is able to improve the processing efficiency of sludge dewatering. Amphoteric flocculant dispersion with water sludge dewatering, poly aluminum chloride(PAC) emulsion compared to the same structure, used in an amount of about 15% -25% reduction.
