2/12/2014, · BOD is efficiently treated in the range of 60 to 500 mg L -1. Wastewaters in excess of 500 mg L -1 BODs have been treated successfully if sufficient dilution is applied in the treatment process, or if an anaerobic process was implemented as a pretreatment process. The biological treatment is effective in removing up to 95% of the BOD.

Chemical oxygen demand, (,COD,) is the amount of oxygen required to fully oxidize dissolved and particulate organic pollution, which is biodegradable and non-biodegradable to CO. This total oxidation is carried out chemically by using a very strong oxidant (potassium dichromate), in a very ,acidic, environment and at about 150°C for 2 hours [5] .

Liu and Lien used a DAF to treat a waste-water from a large-scale bakery. The waste-water was preconditioned by alum and ferric chloride. With the DAF treatment, 48.6 per cent of COD and 69.8 per cent of SS were removed in 10 minutes at a pressure of 4 kg/cm 2 and pH 6.0. Mulligan used DAF as a pretreatment approach for bakery waste.

21/2/2020, · Since the applied voltage is the major driving force of the reaction, a higher voltage results in an increased removal rate. The optimized conditions led to removal efficiencies of around 95 % for both Cyp and COD. Due to the high efficiency and low operating costs, electrocoagulation is a promising technology to treat cattle wastewater.
