COD

A novel spectrophotometric assay method using home-made reagents that can be used to determine the chemical oxygen demand (COD) in real wastewater is described. The home-made reagents were used instead of the American Hach reagents. The principle of measurement was based on direct determination of t

The discharge of textile wastewater containing dyes in the environment is worrying for both toxicological and esthetical reasons as dyes impede light penetration, damage the quality of the receiving streams and are toxic to food chain organisms. A fluidized bed reactor (FBR) with activated carbon as

Novel integrating electrochemical processes with electrodialysis reversal (EDR) and electro-oxidation were designed as advanced water treatment equipment to meet the most rigorous specifications for the existing wastewater treatment facility of secondary nonradioactive system. Pilot tests of these p

The reuse of wastewater from the dairy industry was investigated using coagulation, adsorption and membrane separation. Dairy industry was chosen as it requires huge volume of water. In recent times, development of newer membranes with high flux/rejection characteristics have increased the probabili

In this study the secondary effluent after ODOBEZ system processing from a textile dyeing factory was recycled and reused in a dyeing bath. A pilot-scale combined system of a bio-activated carbon reactor (BAC) and membrane separation module (MS) was constructed and studied in detail. Through the eff

Filtration performance and fouling of nanofiltration (NF) and reverse osmosis (RO) membranes in the treatment of dairy industry wastewater were investigated. Two series of experiments were performed. The first one involved a NF membrane (TFC-S) for treating the chemical–biological treatment plant ef
