ABSTRACT
The supernatant is optionally treated with activated carbon to remove residual soluble proteins and fatty acids prior to discharging into a sewage system. The continuous anaerobic degradation of vapor condensate from a sulfite cellulose process and mixed brewery wastewater was investigated using a variety of carriers in eleven single-stage biofilm fluidized bed reactors. A multistage powdered activated carbon adsorption treatment was effective for treating wastewater after cell aggregate removal by centrifugation from monosodium glutamate manufacture with a chemical oxygen demand removal efficiency of >95%. Oxidation, bleaching, decolorizing with activated carbon, and the products made from the refined wax have been reviewed. An activated sludge process for treatment of wastewater with high organic load, mainly polysaccharides, includes nitrogen and phosphorus nutrients, powdered activated carbon, and an enzyme-bacteria micelle biocatalyst complex. The problems related to the treatment of the effluent were discussed to include excess total organic carbon and filtration difficulty due to the large amount of gum arabic colloids.
