Treatment of Electroplating Wastewaters using Waste Ferrous Sulfate and Wood Fly Ash

The purpose of this work was the development and testing of a simple cost-effective treatment of waste waters originated from electroplating processes using waste Fe(II)-sulfate and wood fly ash. Ferrous-sulfate was employed for Cr(VI) reduction whereas neutralization and heavy metal removal from EWW was performed using wood fly ash. Optimum amount of ferrous sulfate and wood fly ash needed for successful treatment of EWW, optimum pH value of the treated solution and mixing time were determined. Various leaching tests were conducted on the remaining waste mud, which bound heavy metals from the waste water in order to determine a safe way to its permanent disposal. Heavy metals removal efficiency varied from 97.5% for Cu to 99.973% for Zn. Satisfying results can be achieved already at the pH 8. The method is suitable for the purposes of waste water treatment and disposal in compliance with environmental laws. Reported new procedure is technically simpler, cheaper and requires less space compared to the classical methodology because all reactions (chromate reduction, neutralization and heavy metals removal) could be conducted in only one container. Significant improvement in waste water treatment lies in the fact that both reagents (ferrous-sulfate and fly ash) are used in their original form (solid state) whereby any sort of preliminary processing isn’ t needed.
