The Study of Soluble Microbial Products in Submerged Membrane Bioreactor (Part 1: Residential Quarter Wastewater)

The objective of present study is to study impact of sludge retention time (SRT) and hydraulic retention time (HRT) on Soluble Microbial Products (SMP), Proteins and Carbohydrates for residential quarter wastewater. The experiments have been performed on laboratory-scale hollow fiber submerged membrane bioreactor (MBR) for two different seasons. The two seasons considered was dry season i.e. summer season and another is wet season i.e. rainy season. For residential quarter wastewater, the SMP is varied from 7.9 to 8.6 mg/l. Protein is varied from 4.0 to 5.8 mg/l. Carbohydrate is varied from 2.4 to 4.25mg/l and C/P ratio is varied from 0.47 to 1.20. It is observed that SMP and Carbohydrates are increase with increase in SRT and HRT and Proteins decrease
