A METHOD AND AN AGENT FOR CHEMICAL PURIFICATION OF WATER BY MEANS OF CHEMICAL PRECIPITATION AND MAGNETIC SLUDGE SEPARATION.

摘要

A method and a chemical purifying agent for water, specially WASTE WATER, with subsequent magnetic separation of the mud. A precipitation agent comprising, as component of aluminum sulphate and / or iron sulphate is mixed with a magnetic material to effect purification. To ensure an even distribution of magnetic material in the composition of the agent was added aluminum sulfate and / or iron when said component is in the state of melt or solution before crystallization takes place of said composition.
