Development of a complex of detergents for membrane units in the dairy industry

Aim. Development of a complex of detergents (acidic, alkaline, enzymatic, chlorine-containing, surfactant-containing additives) for membrane units used in the dairy industry. Materials and Methods. Methods for controlling the concentration of active substances in concentrates of agents are given on the example of KATELON 202 - determination of total acidity by the method of acid-base potentiometric titration (in terms of HNO3) and KATELON 114 – determination of the mass fraction of active chlorine by redox titration. Results. A complex of detergents for membrane plants (ultrafiltration (UV, UF), microfiltration (MF, MF), nanofiltration (NF, NF), reverse osmosis (RO, RO)), used in the dairy industry and including alkaline non-foaming, medium-, low-foam products KATELON 109, KATELON 110, KATELON 115; alkaline chlorine-containing non-foamy agent KATELON 114; acid non-foamy KATELON 202, KATELON 207, KATELON 208; high-foam neutral additives KATELON 308 and KATELON 309 – enhancers of the washing effect for KATELON 109, KATELON 110, KATELON 115; preservative non-foaming additive KATELON 310 for protection from microbiological contamination; enzyme medium supplement KATELON 601. The composition of all products, their brief characteristics and physicochemical indicators, as well as an approximate program of washing with a complex of developed preparations are given. The dependences of pH and electrical conductivity were obtained for KATELON 109, KATELON 110, KATELON 115, KATELON 202, KATELON 207, KATELON 208. Conclusion. The complex of detergents is successfully used at Kopylsky Butter Cheese Plant, Lyubansky Cheese Making Plant, Minsk Dairy Plant No. 1, Verkhnedvinsky Butter and Cheese Plant, Molodechno Dairy Plant, Volozhin production site of Minsk Dairy Plant No. 1, Tolochin Branch of Lepel Dairy Canning Plant.
