Results of use of polymeric non-oxidizing reagent (“Aquaton”: poly-(hexamethylene diamine, guanidinium hydrochloride) – EU; polyhexamethylene guanidine hydrochloride – RU) for treatment of wastewater and creation of factory turnaround water supply system were shown. It was shown that use of reagent “Aquaton” allows to achieve satisfying degree of water treatment and prevent microbial growth in turnaround system and sediments.

Key words: “Aquaton”, wastewaters, efficient treatment, turnaround water supply, microbial growth.

Physical and chemical regularity and the mechanism of process complex coagulation and oxidative wastewater treatment, low-purity by surfactants and dyes are investigated. The basic regularity of regeneration of valuable components of the sludge formed after complex wastewater treatment is revealed. High performance of use of regenerated solution of a coagulant for discoloration of typical wastewater in a mix with original solution of iron (II) sulphate is established.The extent of discoloration remains high during four cycles and exceeds 90 % at a doze of iron of 120 mg/dm3.

Key words: complex coagulation, oxidative treatment, wastewaters, SAA, sludge.
