Composite coagulant POLVAKTM is a blend of alunimium oxychlorides, sulphates, oxysulphates.
FIELD OF USE:
Composite coagulants POLVAKTM are used for treatment of drinking water, surface and underground water, wastewater treatment as well as treatment of effluents of different types of industries.
Compared with standard coagulants POLVAKTM composite has the following benefits:
–– High coagulation capacity;
–– Reduced consumption rate;
–– Low sensitivity to the temperature of treated water;
–– High reaction rate at low temperatures.

It is recommended to batch as trade solutions. Variability of the modifier’s nature and its concentration in the body of coagulants POLVAKTM composite allows to make individual selection of max effective products in accordance to customer’s demand. It is possible to produce composite coagulant Polvak-blend that would contain organic coagulant.
TRANSPORT AND PACKAGING:
Coagulant is loaded into IBC containers of 1 m3 capacity on a palette, in 20 dm3 cans and in bulk to automobile tankers or tank-wagons with corrosion-resistant coating. Transportation is made by all kinds of transportation, except for air, in covered transportation means of in accordance to freight transportation regulations applicable for this type of transportation.
Tanks with corrosion-resistant polymeric coating. If the tanks were previously used to store another coagulant, it should be thoroughly cleaned from its residue to prevent sedimentation. Periodical inspection and cleaning is recommended.
WARRANTY SHELF LIFE:
12 months from the production date.
