Treatment of acidic electroplating effluent from small scale industries using batch and continuous flow adsorption reactor
Abstract
<jats:title>Abstract</jats:title><jats:p>If electroplating effluent discharges aren't properly treated, they have a detrimental effect on the aquatic ecology.The effluent characteristics comprise heavy metals (chromium, nickel, zinc, and iron), COD, TDS, and minerals (phosphate, nitrates, and sulfates) that were toxic to all ecosystems. A few techniques, such as coagulation, adsorption, membrane techniques, and electrochemical techniques, are available for treating the effluent alone. Adsorption was the most extensively used method among them all since it was economical and required minimal technical expertise.This study describes the removal of Cr6+ using activated carbon (commercial) in a batch and continuous flow study. The effluent characteristics: pH-2 to 3, TDS > 2000mg/L and with 360 mg/L of Cr6+ concentration. In the column study, 50g of 7 different grades of activated carbon (GAC and PAC) was filled in separate columns. The complete removal of Cr6+ was obtained at 80*200, -325, and -200 mesh sizes for further experiments 80*200 was selected. In the batch study, different dosages of 80*200 AC (1g-6g) were added to a batch reactor (200ml) and maximum removal of 83% was achieved at 5g. It was observed the pH level gets augmented and TDS levels were dropping. In the isotherm study, the data were fitted with Langmuir isotherm and Freundlich isotherm which resulted in the fitting of Langmuir isotherm better. The continuous flow studies experimented with constant inflows of 50ml/min in an 80*200 AC (4Kg) bed. The pH rises from acidic to alkaline and a gradual inclination of pH was observed. The removal of TDS and Cr6+ was depreciated with time and Cr6+ concentrations were detected using UV-VIS spectroscopy: Diphenyl carbazide method. The morphological and elemental analysis was determined by using SEM and Edax before and after treatment.&#xD;</jats:p>
