Rezumat

The complex reagent, sold under the trade mark AKFK - a new alumosilicic flocculantcoagulant - has both coagulating and flocculating properties. It ensures higher level of water purification from petroleum products in comparison with reagents that are conventionally used in Russia. The wide use of AKFK is constrained by the ability of the reagent to form a gel, which leads to a loss of its commercial characteristics. Short-term ultrasonic treatment facilitates the preservation of an active silicic acid sol and prolongs the shelf life of AKFK more than twofold.
