Membrane processes have been successfully employed for treatment of a large number of industrial effluents. Reverse osmosis (RO) and ultrafiltration (UF) are versatile separation and purification tools for the process industries. Both of these techniques are based on the ability of pressure-driven filtration membranes to separate multi-component fluids based on molecular size, shape, and chemic...

Lead contamination in water is a widespread problem throughout the world and results from industrial use and processing of lead ore. Bio-availability of lead can be hazardous for children and causes mental retardation. The use of lead free petrol is one measure to check this pollution, but this heavy metal is also present in industrial effluents and need to be removed before these effluents are...

Abstract Industrial effluents containing appreciable amounts of phenol and formalin may represent a problem when these effluents undergoing biological treatment. Experience in field of biological treatment for wastewater contains high concentrations of formalin showed high inhibition effect of formalin to biodegradation, specifically at higher concentrations more than 225 mg/L [3]. Also, as phe...

The present study aimed to assess and compare the ability to remediate synthetic textile and industrial wastewaters by Fenton treatment, a biological system and sequential treatments using Aspergillus niger (A. niger). All studied treatments were found to be effective in decolorization of the effluents under study. Fenton treatment followed by A. niger showed excellent potential for the maximum...

The potential cytotoxicity and genotoxicity of three industrial wastewaters (brewery, rubber and bottling) in Benin metropolis using the Allium cepa test were investigated. A series of five small onion bulbs were cultivated in 0.01, 0.1, 1, and 10% of the wastewaters (v/v) and after 48 hours, one root tip from each bulb was harvested and processed for cytological studies by the aceto-orcein squ...
