Abstract

Joint Stock Company «Apatit» is the world’s largest producer  of phosphate raw materials  for the production of mineral fertilizers. The processing of ore and obtaining of apatite and nepheline concentrates are carried out at the ore treatment factory   ANOF-2. Nowadays there is an acute problem of additional wastewater treatment in concert with the presence of nitrites, fluorides, phosphates, aluminum and molybdenum in flows the concentrations of which exceed the established  standards. Using the fine cleaning filters, the filter material of which is made of synthetic fibers, the quantity of waste substances dropped into the water can be reduced. The using of such filter system will allow decreasing the damage  to the  environment  and reducing the  enterprise payouts for the discharge of pollutants.
