Sažetak
The objective of this paper is to study the possibility of treating waste water with activated clay and with an activated mixture of clay and an industrial powder which induces coagulation. Coagulation resulting from physical contact, i. e. from the collision between soft particles of aggregation of the colloidal suspension in water and hard rigid granules of various powders is called contact coagulation. It is unlike classical or volume coagulation which result from mixing the soft particles from the wastes with hydrolyzed Al and Fe salts. Contact coagulation is illustrated by the results obtained from treatment of the waste water released from a slaughter house and a dairy, by the coagulation with the activated clay mixture and pulverisation from fumes released from the steel production furnaces. A strong anion flocculant was used for flocculation. A decrease of COD in the treated water from the slaughter house ranged from 75-89%, and in the waste water released from the dairy from 54-82%. The advantages of contact coagulation and the possibility of using various industrial waste by-products with a good ability of absorption for waste water treatment are pointed out in this paper.
