Sleeper impregnation plants treat sleepers, switch ties, wooden poles and other wood products with special antiseptics. Wastewater from these facilities contains various pollutants, mostly emulsified tar, creosote, anthracene or shale oil. For purification purposes, it is passed through tar traps or flotation units. The coagulation method is applied. Ozonation and filtration are used for further purification.
