Study of properties of aluminium hydroxide obtained with electrical discharge

摘要

Sedimentation capacity and adhesion properties of aluminum hydroxide obtained by the method of high-voltage pulse discharges at the aqueous medium with metal loading have been investigated. It has been experimentally shown the method of obtaining of aluminum hydroxide in some times lower than that by electrolysis on power inputs. More high speed of a silt deposition has been found at processing water by ''electrodischarged" aluminum hydroxide in comparison with chemical coagulant. The heightened adhesive power of the "electrodischarged" coagulant has been defined as contrasted to the chemical one.
