5 Applications of MBR After discussing the optimum operating conditions, configurations and types of MBR, it is important to know how the MBR is employed to real life and where it can be used this is illustrated below. 5.1 Industrial WWT Generally, industries produce different products with small amount of undesired products compared to the main product. These undesired products can be discharged to environment and specially water bodies and cause severe problems. Consequently, MBR is used commonly to treat various types of WW and different studies approved that. Hosseinzadeh et al. reported that MBR approached a high removal efficiency of COD, TSS and total nitrogen TN to be 75%, 98% and 74% respectively [--]. Another study done by Cheng…show more content…
Cosmetic materials consist of high COD values, fats, oils, and cleaners and of course different colors. Discharging these wastes to water bodies can cause harmful effects to environment and human health, though several treatment processes have been employed to treat this type of WW such as chemical processes like flocculation coagulation, biological processes like CAS, and biological –filtration processes like MBR (Bautista et al., 2010). During the years, the MBR process is the representative method of advancement over the CAS process. The combination of biological degradation and membrane filtration allows the process to be more flexible as it has been known about the MBR (Hai and Yamamoto, 2011). In addition to that, the MBR fouling is the only problem that may affect the performance because of oily and colored wastes (Johir et al., 2012). Friha and Fatma reported the result of treating a sample of cosmetic WW and it was found that the removed surfactants reaches 98% and COD approaches 84%. The effect of higher load of organic matter was studied as well and how it affects the performance of MBR [Friha Inès, Fatma
