Abstract

The invention relates to processes for dephosphatation of sewage waters, particularly sewage waters formed at the livestock farms.The process, according to the invention, includes treatment of waters with a coagulating-precipitating agent, the coagulation-precipitation of phosphates and their separation by filtration, at the same time as coagulating-precipitating agent is used sugar production defecate, taken in a ratio of the calcium content recalculated in respect of the phosphor content in the sewage waters of (5...7):1.
