Conventional coke plant wastewater treatment utilize physicochemical and biological methods. Among the proven biological treatment methods of coke plant wastewater,
activated sludge processes is commonly used
In many countries, including Poland, preferred system is based on a
single-sludge process with recycle of nitrified effluent, i.e. predenitrification process .
Despite complex treatment coke plant wastewater can have adverse
impact on ecosystem and human health
Increase of efficiency of coke plant wastewater treatment is
possible by application of adsorption methods. Many research confirmed removal of phenols
cyanide , PAHs and other organic compounds from industrial wastewaters after utilization of organic sorbents
