Implementation of adsorption methods to treat coke plant wastewater runs up against a cost barrier emerging from high
prices of commercial sorbents.
High cost is due to troublesome regeneration of the used sorbents .
The most common thermal regeneration of coal consumes lot of energy and results in 5–10% mass loss of regenerated coal .
An attempt to overcome this barrier is made by using materials with fairly good sorptive properties and the lowest possible price, enabling a single application without need of regeneration.
Studies showed that coke dust generated in coke plants using coke dry quenching methods
can be used as such material .
The coke dust is a by-product of the coke plant production process and is less expensive than commercial powdered
activated carbons (PAC) by at least order of magnitude.
