A METHOD AND AN AGENT FOR CHEMICAL PURIFICATION OF WATER BY MEANS OF CHEMICAL PRECIPITATION AND MAGNETIC SLUDGE SEPARATION |
摘要 |
A method and an agent for chemical purification of water is provided, especially waste water with subsequent magnetic sludge separation. A precipitation agent comprising as component aluminium sulphate and/or iron sulphate is used together with a magnetic material for the purification. In order to provide uniform distribution of the magnetic material in the agent composition it is added to the aluminum and/or iron sulphate component of the composition when said component is in the form of a melt or solution prior to crystallization of said composition. |
