“…The effect of sludge properties on the filtration characteristics of sludge layers formed on MF/UF membranes, represented by the extent and rate of MF/UF membrane fouling, has been extensively studied in MBRs via statistical analysis [17][18][19][20][21]. Various sludge properties were identified to have either strong or weak positive/negative correlations with MF/UF membrane fouling, depending on the given investigated conditions.…”

“…Kornboonraksa and Lee (2009) reported that an increase in influent COD, biological oxygen demand (BOD), and NH 4 eN from 1150 to 2050 mg/L, 683 to 1198 mg/L, and 154 to 248 mg/L, respectively, resulted in a decrease in the removal efficiency of COD, BOD, and NH 4 eN. An increased OLR decreases the filterability of the MBR.…”

This review discusses the characterization, production and implications of soluble microbial products (SMPs) in biological wastewater treatment. The precise definition of SMPs is open to talk about, but is currently regarded as “the pool of organic compounds that are released into solution from substrate metabolism and biomass decay”'. Some of the SMPs have been identified as humic acids, polysaccharides, proteins, amino acids, antibiotics, extracellular enzymes and structural components of cells and products of energy metabolism. They adversely affect the kinetic activity, flocculating and settling properties of sludge. This review outlines some important findings with regard to biodegradability and treatability of SMPs and also the effect of process parameters on their production. As SMPs are produced during biological treatment process, their trace amounts normally remain in the effluent that defines the highest COD removal efficiency. Their presence in effluent represents a high potential risk of toxic by-product formation during chlorine disinfection. Studies have indicated that among all wastewater post-treatment processes, the adsorption by granular activated carbon combined with biologically induced degradation is the most effective method for removal of SMPs. However, it may be concludes that the knowledge regarding SMPs is still under progress and more work is required to fully understand their contribution to the treatment process.
