Sanitary and epidemiological safety and efficiency of silicocarbonic sorbent used for removing oil and oil products from water

Summary

The results of research for the sanitary and epidemiological eva­luation and determination of the efficiency of using TSHR silicocarbonic sorbent manufactured by «Khiminzhiniring» LLC for removing oil and oil products from water are presented. Sorption methods based on the physical and chemical interaction of oil with solid oil absorbing material – sorbent efficiently remove oil from the surface of water bodies. The use of sorbent can be combined with mechanical methods of oil spill skimming and biological methods of decomposition of oil collected from the sorbent surface. The investigated TSHR silicocarbonic sorbent is a product of special thermal destruction of rice husk; it appears as «carbon –silicon dioxide» finely dispersed binary solid structure. With the use of chemico-analytical and toxicological methods the sorbent safety related to toxic and allergic action was studied as well as its capability to remove oil components and inorganic substances from water. Sorption methods based on physical and chemical interaction of oil with solid oil absorbing material – sorbent proved to be efficient in removing oil from the surface of water bodies. The use of sorbents can be combined with mechanical methods of oil spill skimming and biological methods of decomposition of oil collected from the sorbent surface. As a result of studies it was stated that TSHR sorbent met the sanitary and epidemiological requirements. The model tests revealed the sorbent efficiency in removing phenol, methylnaphthalene, chloroform, ethanol and inorganic compounds. It proves the possibility of using TSHR sorbent not only for removing oil from water in water bodies but also for water purification for drinking and other purposes. The necessity of carrying out additional field studies to determine wider range of dissolved oil components and the efficiency of sorbent use for removing oil film and dissolved substances is stated.
