ALUMINIUM HYDROXYCHLORIDE POLVAK™
POLVAK™ is an aqueous solution of aluminium hydroxychloride with general formula Al2(OH)nCl6-n, that conform to РАС (polyaluminium chloride) coagulants in accordance to European classification.
FIELD OF USE:
Treatment of drinking water, surface and underground water, municipal sewage as well as treatment of effluents of industrial (metallurgical) plants, paper and cardboard plants, oil refineries and wastewater treatment.

COMPARED WITH ALUMINIUM SULPHATE POLVAKTM HAS THE FOLLOWING BENEFITS:
– High coagulation capacity;
– Reduced consumption rate;
– Low sensitivity to the temperature of treated water;
– High reaction rate at low temperatures;
– Residual aluminium content in purified water is lower than requirements in National Standards;
– Virtually no change in alkalinity of water;
– Work in a broader рН rate.
It is recommended to batch as trade solutions. It should be noted that transfer to usage of new reagent in terms of the acting station usually do not require reconstruction of the existing treatment facilities that greatly facilitates he staff work.
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 or air, in covered transportation means of in accordance to freight transportation regulations applicable for this type of transportation.
Tanks with corrosion-resistant polymeric coating made of polyethylene, polypropylene, polyvinylchloride, fluoroplastic, etc. If the tanks were previously used to store another coagulant, they should be thoroughly cleaned from its residue to prevent sedimentation. Periodical inspection and cleaning is recommended.
WARRANTY SHELF LIFE:
12 months from production date.
