  1. 1. INDUS ECOWATER PRIVATE LIMITED www. modernstp.com for sewage recyclefor sewage recycle
  2. 2.  Membrane Bio Reactor (MBR) is a combination of biological activated sludge treatment processes and physical filtration using Ultra-Filtration Membranes  Ultra-Filtration membranes are similar to Reverse Osomosis Membranes with bigger pores  MBR produces high quality water with low BOD and Suspended Solids suitable for re- use  Treated water from MBR is crystal clear
  3. 3. Submerged Side stream
  4. 4.  Cost of Submerged Membranes is more than double that of side stream membranes  Due to lower flux, more submerged membranes are required than side stream membranes for the same volume  Bigger aeration tanks are required for submerged MBR  Bigger air blowers are required for submerged MBR  Complex automation is required for submerged MBR
  5. 5.  In submerged MBR, membranes are directly immersed into bioreactor with highly concentrated mixed liquor suspended solids.  MLSS contains high levels of dispersed, small particles comprising of inert and colloidal material.  High membrane fouling environment, which results in low membrane flux rates, results in large membrane surface area.
  6. 6. MBR HIGH MEMBRANE FOULING ENVIRONMENT HIGH ENERGY CONSUMPTIONINTENSIVE PRESCREENING & DISPOSAL LARGE EQUALIZATION BASIN HIGH MEMBRANE AREA SUBSTANTIAL OPERATOR TRAINING
  7. 7.  MBR HAS LOW FLUX – i.e, More Membrane surface area is required for submerged MBR as compared to Side stream MBR  MBR REQUIRES 1 mm FINE SCREENING- Fine screening removes substantial amount of untreated waste that must be disposed off by other means. Fine screening requires additional equipment like cutters etc that consume power.  MBR REQUIRES HIGH MEMBRANE AIR SCOUR RATES – higher air requirement results in higher power consumption
  8. 8. SIDE STREAM MBRSIDE STREAM MBR ADVANTAGESADVANTAGES  Biological process (MBBR) and Membrane Filtration are two separate process units – Enabling maximum total system performance.  Each process unit MBBR & UF are optimized and controlled independently  97% less Suspended Solids in UF membrane feed reduces fouling drastically  THIS DIRECTLY INCREASES THE MEMBRANE FLUX  Even existing biological plants can be upgraded with external UF plant  Simple Micro-controller automation is sufficient for UF
  9. 9. SIDE STREAM MBR ……SIDE STREAM MBR ……  CAN TOLERATE MODERATE PEAK FLOW RATES.  WILL REQUIRE SMALLER EQUALIZATION TANK.  NO FINE SCREENING REQUIREMENT.  NO SLUDGE RECIRCULTION- ENERGY SAVING.  NO AIR SCOURING REQUIRED- ENERGY SAVING.  SINCE MLSS IS LOW IN MBBR, OXYGEN TRANSFER EFFICIENCY IS HIGH REDUCING AIR REQUIRED  FLUX RATES CAN BE MUCH HIGHER, SAVES COST OF MEMBRANES.  SINCE MLSS IS VERY LOW, MEMBRANE FOULING MINIMUM.
