Treatment of Dye Waste Water using Moving Bed Biofilm Reactor and Granular Activated Carbon with Neem Leaf Powder

Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains organic substance, high colour with COD low BOD. This water directly streams thus contaminate groundwater. To treat wastewater, is simple physio-chemical not sufficient for removal pollutants. So that biological followed have been required. this study, experiment was carried out reduce colour, COD, BOD, Heavy metals laboratory scale Moving Bed Biofilm Reactor Granular activated Carbon bed (GAC NLP-MBBR) Neem leaf powder. A thick granular carbon used adsorption technique wastewater. GAC 8cm layered by Ennore sand 3 grades 4cm equally. Then MBBR operated continuously retention times. polypropylene type bio balls were microorganism attachment MBBR. outlet treated membrane process. Membrane process moving membranes reduces pH, contents, heavy metals, turbidity etc., final effluent suitable Irrigation.
