CLEANING PETROLEUM PRODUCTS FROM WASTE WATER WITH COMPOSITE FILTERS BASED ON WASTE PRODUCTS

摘要

The possibility of cleaning petroleum products from waste water with composite filters manufactured from various waste products (cotton lint; wheat, millet, and sunflower husk; sawdust) is studied. As a result of studies it is established that waste products have a high absorption capacity and cleaning efficiency (88-89%) of oil contamination from waste water. A three-layer filter-absorbent is prepared with an internal layer of mixed cellulose-containing waste that is as good as Russian and overseas analogs.
