Abstract
The research of a spent kieselgur obtained during beer filtration as a sorbent for cleaning of waste waters from oil. The thermal processing of a spent kieselgur influences over its ability to remove oil in the process of cleaning of waste waters. It has been discovered that the highest degree of removing oil from standardized test solutions of waste waters is provided by a spent kieselgur modified at a temperature of 400 °C. Modifying a spent kieselgur with sulphuric, hydrochloric and phosphoric acids at different temperatures increases its sorption properties in relation to oil. The maximum removal of oil from standardized test solutions of waste waters is achieved by using a spent kieselgur modified with 20 % sulphuric acid at 100 °С for cleaning them. Using a modified spent kieselgur allows increasing the degree of cleaning of waste waters contaminated with oil.
