... fluidized bed reactor (FBR) with activated carbon as support material has been used to investigate the removal efficiency of chemical oxygen demand (COD), biochemical oxygen demand (BOD), and color of textile wastewater. The FBR was fed continuously without supplemented (Phase 1 and 2) and supplemente ...

... electro-oxidation process. From the results of the analysis of the EDR product, it was found that it is possible to reuse water with less than 2 ppm COD and 8 ppm T-N. The possibility of scale formation by calcium carbonate was considered from the Langelier Index (LSI). In the case of the EDR proces ...

... dairy farm and was found that the water can be recycled or reused. Keywords: Dairy wastewater; Coagulants; Powdered activated charcoal (PAC); TDS; COD; Membrane processes 1. Introduction Ever increasing industrialization and rapid urbanization have considerably increased the rate of water pollution.

... carbon via special bio-augmentation, but also alleviate the damage and fouling of membrane due to the further reductions in chemical oxygen demand (COD), suspended solids and color of influent after BAC; this lengthens the lifetime of membranes. In addition to the recycle and reuse fraction of th ...

... increase while the feed flowrate decreased and the pressure increased. Membrane fouling resulted in permeate flux decline with increasing the feed COD concentration. Furthermore, the flux decline due to the COD increase was found higher at higher pressures for both NF and RO membranes. The effec ...

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 o ...
