1∗The program of control involves specific indicators with the account of the technology of water conditioning from the cited list.
2∗The program of control involves specific indicators of using respective reagents and calculating them based on the analysis of the content of the monomer in the commodity flocculant. The reagent doses and the level of the monomer should correspond to the following requirements: at the polyacrylamide dose 1 mg/dm³ the content of acrylamide in it should not exceed 0.05%.
