Comparison of the performance of submerged membrane bioreactor (SMBR) and submerged membrane adsorption bioreactor (SMABR).
This study focuses on comparing the performance of submerged membrane bioreactor (SMBR) and submerged membrane adsorption bioreactor (SMABR) over a period of 20 days at a hydraulic retention time (HRT) of 3.1h. The effects of PAC on critical flux and membrane fouling were also investigated. The SMABR exhibited better results in terms of mixed liquor suspended solids (MLSS) growth, DOC removal (...
متن کاملThe Study of Organic Removal Efficiency and Membrane Fouling in a Submerged Membrane Bioreactor Treating Vegetable Oil Wastewater
The characterizations of vegetable oil wastewater (VOW) are unpleasant odor, dark color, and high organic contents, including large amounts of oil and grease (O&G), chemical oxygen demand (COD), fatty acids and lipids. Therefore, VOWs should be treated efficiently to avoid the environment pollution. The aim of present study was the investigation of VOW biological treatment using membrane biorea...
متن کاملA comparison study on membrane fouling in a sponge-submerged membrane bioreactor and a conventional membrane bioreactor.
This study compared membrane fouling in a sponge-submerged membrane bioreactor (SSMBR) and a conventional membrane bioreactor (CMBR) based on sludge properties when treating synthetic domestic wastewater. In the CMBR, soluble microbial products (SMP) in activated sludge were a major contributor for initial membrane fouling and presented higher concentration in membrane cake layer. Afterwards, m...
متن کاملA new combined inorganic - organic flocculant ( CIOF ) as a performance enhancer for aerated submerged membrane bioreactor
In this study, a new combined inorganic-organic flocculant (CIOF) of FeCl3 and membrane performance enhancer (MPE50) was prepared and added to an aerated submerged membrane bioreactor (SMBR). The effects of CIOF on the performance of an aerated submerged membrane bioreactor (SMBR) were evaluated. The results indicated that the SMBR with CIOF addition could remove almost 100% total phosphate whi...
متن کاملcomparing the sludge characteristics in a moving bed membrane bioreactor and conventional membrane bioreactor
the properties of excess sludge wasted from two parallel pilot plants membrane bioreactor (mb-mbr and conventional mbr) have been monitored. sludge samples of mb-mbr and mbr have been examined and compared in terms of vss/tss, filtration index, eps and smp concentration, nitrogen and phosphorous in dry matter, fi, svi and polyelectrolyte requirement for sludge conditioning. by keeping similar o...
