"The main advantages of the innovative oil sorbent are magnetically controllability and buoyancy. The basis of the sorbent is a magnetite core, which allows you to attract the oil film in reservoirs and manage it for effective spill response, " explained the project manager, Associate Professor Elena Ushakova.
According to the developers, Kuzbass sorbents will be able to work effectively at very low temperatures, strong winds and even under ice, which makes their use in the Arctic promising. To collect oil with such a sorbent, it is necessary to use special electromagnetic installations. With their help, the core of the sorbents will be attracted, which will help to control the oil slick on the water. Absorbs oil innovative development with a carbon housing. It is made by granulating waste from coal, livestock and woodworking enterprises, including activated sludge from sewage treatment plants.
"There is a lot of waste in Kuzbass that can be disposed of by getting magnetically controlled oil sorbents. You can make a batch of sorbents with ready-made biomass in just one day. For the production of 1 kg of oil sorbents, approximately 280 g of biomass is required - excess activated sludge, 900 g of coal dust and 50 g of magnetite, " the university said.
Kuzbass scientists are improving the development, studying various methods of heat treatment of the magnetite core, the limits of its heat resistance and strength.
