It is known that while cleaning water contaminated in production process, various methods (biological, chemical, physical-chemical, flotation, coagulation etc.) are applied. Coagulation and flotation from physical-chemical methods are widely used. Using hydroxides of metals as coagulant in water cleaning enables cleaning from polycyclic aromatic hydrocarbons as well. As a result of studies it was defined that these methods are not rational. In selection process of the method not only its rationality but also low cost is considered. In our opinion, biological cleaning method carried out with bacteria is more cost effective from environmental and economic point of view. 

The results of researches conducted justified that depending on cleaning time simple cane and water hyacinth show higher efficiency. The efficiency of cleaning with simple cane in five days comprises 95.6 % while with water hyacinth it is 97 %.
