Coke Gas Production Waste Water Stream Treatment Plants

The coke-making process is strictly connected with the formation of coke oven wastewater, highly loaded and contaminated stream, proper treatment and utilization of which requires sophisticated methods and technologies.

This wastewater is defined as a mixture of technological streams, which are formed during coke oven gas cleaning and coal-derivatives production, and sanitary wastewater formed at coke oven plant. Due to the composition and specificity of contaminants present in coke oven wastewater (such as phenol, high COD, cyanide, etc), its proper treatment requires the involvement of

physical, chemical, and biological methods, which often proceed with additional polishing.

Through the state-of-the-art wastewater treatment plant technology of today, we are designing cross-flow UF and cross-flow RO / NF systems.

Bioreactors followed by cross-flow type UF systems are much more effective in terms of removing cyanide, high COD, phenols, etc. The process configuration is such that; The biomass is filtered in a filter installation next to the bioreactor. The membrane modules are placed in a pressurized circulation loop located outside the bioreactor. Membrane fouling is prevented by the use of the shear forces created by the cross-flow operation of the membranes.

Besides, we, as GLANCO RECOVER & RECYCLE, claim to generate Ammonium Phosphate fertilizer by stripping the ammonium from wastewater (as well as absorbing it by sulfuric acid) sourcing out from the “coke oven gas production process”.
