Abstract:
A method for treating waste water based on high speed coagulation-flocculation and sedimentation which method is conducted in an arrangement for treating waste water based on a high speed aggregation and sedimentation, comprising a mixing tank, an agitating tank, a polymer aggregation tank and a sedimentation tank successively connected, said arrangement being provided with transporting lines for transporting to the mixing or agita produced in the sedimentation tank, comprising introducing into the mixing tank said waste water and an aggregating agent which is based on clay minerals including zeolite or bentonite as a main component, introducing into the agitating tank said waste water and an inorganic coagulant, introducing into the polymer aggregation tank said waste water and a polymeric flocculent and introducing a combination of glass particles and kieselguhr into at least one of the mixing, agitating and polymer aggregation tanks to convert the sludge resulting from treating the waste water into reusable porous ceramics.
