 The term “polishing” refers to methods and processes supplementing common treatment of water of a given composition. Due to wide spread of bio-chemical treatment (BCT) of general waste water flow mechanical treatment is considered to be a primary treatment, biological-secondary, polishing tertiary. There at polishing yields achievement of any required and achievable degree of pollution removal or destruction. Sorption at activated coals allows additional extraction from water after BCT of more than 80 % of remained impurities.
