DESALINATION AND WATER TREATMENT
The study emphasized a new approach for modeling the activated sludge process with a membrane separation (MASM) for organic carbon removal of tannery wastewaters. The new model, differing from the commonly used activated sludge models 1, relied on a modified chemical oxygen demand (COD) fractionation considering the particle size distribution of the organic matter. A new COD fraction, entrapped COD, was included into the model related to the effective filtration size of the membrane module.doi:10.5004/dwt.2021.26902 fatcat:opx7qi6dpzbl3e6txl5dn2fu4a
