Use of PET granules for improving a surface runoff treatment

Abstract

Pollution of surface and ground waters by surface (rain and melt) waste water is a big problem for many countries of the world. In addition to anthropogenic factors leading to the pollution of surface runoff, one should add runoff, which is formed after extinguishing fires of various scales and territories. As a result of extinguishing fires, a large amount of pollutants enters surface wastewater, which creates an additional load on soils, groundwater aquifers and water bodies. The paper proposes a wastewater treatment method using PET granules and polyurethane foam granules as a filtering layer. The use of PET packaging waste for the purification of rain and melt wastewater allows to reduce the anthropogenic load on the environment and to increase the use of plastic waste
