This paper enlists the research work done in direction of finding alternative methods of treatment of waste water. Use of different types of membranes is still being done to treat the water to enhance the performance of water filtration by membranes.In DF as the name suggests, there is a direct filtration of raw water, without any prior treatment. The filter being exposed to the raw water directly, due to direct exposure of raw fed water the performance of filter being affected and the pores of the filter may get blocked. Testing with pore size of 0.03 micrometer ultrafiltration method (Polyvinylidene fluoride) showed by using this technique. A high quality effluent is produced while sustaining a high membrane flux simultaneously. By filtration through this method, a highly concentrated fraction of waste water is obtained which is reduced in volume but has high amount of solids and organic strength which then has to be treated by other methods.Thus to overcome this problem we propose coupling of direct membrane filtered with an anaerobic membrane bioreactor which can deal with high amount of solids and organic strengths being produced in waste.An MBRs are used in treatment of industrial strength waste water which is high in COD. This method may not be completely suitable with domestic waste water which is the generally low in COD. But if we couple DF with An MBR, the low strength domestic waste water can be treated efficiently. By coupling DF and An MBR we can deal with liquid fraction of waste water by DF and highly concentrated organic part of waste by An MBR, thus improving the efficiency and energy profile of An MBR.So during the research we have to deal with various flow and mass equations according to which best suitable design can be chosen.due to highly concentrated solid waste being generated in this method there are chances of membrane fouling over few weeks and months. Due to absence of any systematic method, that may determine how the process changes may affect the performance the performance of method. Due to this occurring problem, there was a desire to determine fouling propensity. MPI (Modified Propensity Index) that was previously used in sea water. RO dissemination is now being applied to this method to find out fouling propensity.This method to find out fouling propensity will be applied to raw domestic waste water, concentrated domestic waste water and the liquid fraction obtained during filtration. Adsorption can also effectively reduce fouling during this method. So the effect of PAC ( Powdered Activated Carbon) on fouling propensity is also to be determined.
