At the first stages of operation, reactors were feed by a mixture of municipal wastewater and synthetic wastewater. Full acclimatization of the microorganisms to synthetic wastewater was achieved in 60 days.

    In this study, steelmaking slag is selected as an adsorption material to treat coke-oven wastewater. The study shows the use of solid waste to treat liquid waste of the same industry. The full effect of adsorption on steel slag with coke-oven wastewater has been analysed using SEM, XFR, XRD, FTIR and GC-MS. The adsorption pattern for steel slag at high temperatures, i.e. up to 1100°C was

    Biological treatment is a conventional method used for the treatment of the waste water from the of coke oven and by product plant before its disposal. Because biological oxidation is highly sensitive to fluctuations in constituent loadings and pH, the waste water is first passed through an equalization tank to level out the concentrations, the
