Effects of mixed liquor pH on membrane fouling and micro-pollutant removals in membrane bioreactors for municipal landfill leachate treatment
This research investigated the membrane fouling and micro-pollutant removals in treatment of municipal landfill leachate at various pH levels (i.e. 5.5, 6.5, 7.5, and 8.5) using membrane bioreactors. The findings revealed that membrane fouling was influenced by the pH level of mixed liquor, with pH 5.5 exhibiting the most severe membrane fouling. At pH 5.5, proteins and carbohydrates were ...

Effect of organic fouling on micro-pollutant rejection in membrane bioreactor treating municipal solid waste landfill leachate
Effect of membrane fouling on the removal of micro-pollutants from municipal solid waste landfill leachate, i.e. 4-methyl-2,6-di-tert-butylphenol (BHT), bisphenol A (BPA), and bis(2-ethylhexyl)phthalate (DEHP), in membrane bioreactor (MBR) was investigated. Modifications of membrane surface properties were analyzed to determine their relationship with their removals. Membrane fouling was ...

Application of biofilm membrane bioreactor and Reverse Osmosis membrane to the treatment of fresh and partially stabilised leachate
Membrane Bioreactor (MBR) with sponge cube media and reverse osmosis (RO) were investigated in laboratory scale. Fresh and partially stabilised leachate contained COD/N of 30 and 10 and BOD/COD of 0.7-0.9 and 0.4-0.7, respectively. Continuous and intermittent aeration modes were examined. COD and TKN removals were more than 90%. Highest nitrogen removal efficiency was achieved when aeration of 1 ...
