Use of a Hydrophobized Sorption Material Based on Aluminosilicate Water Treatment Waste for Removal of Petroleum Products from Wastewater

Results of an investigation into the applicability of a sorption material based on aluminosilicate water treatment waste, hydrophobized with a 5 % solution of GKZh-94M siloxane fluid, for the removal of petroleum products from stormwater runoff were presented. The sorption characteristics of the studied material under dynamic conditions were determined, including total and dynamic volumetric capacities, as well as the calculated breakthrough time and protection coefficient. A process scheme for the treatment of stormwater generated at industrial facilities was proposed. The process includes two sorption filters operated according to the concentration of petroleum products in the influent (up to 40 mg/dm 3 ). Pilot-scale industrial tests carried out at a fire station stormwater treatment facility demonstrated a petroleum product removal efficiency of 94 %. Biotesting using the Ecolum test system showed that the toxicity of the treated effluent was reduced to the low-hazard category.
