FCM-MBR for Landfill Leachate Treatment

FCM-MBR for Landfill Leachate Treatment
Landfill leachate is liquid that moves through or drains from a landfill. Leachate varies widely in composition depending on the age of the landfill and the type of waste that it contains. First emerges it can be black in colour, anoxic and may be effervescent with dissolved and entrained gases. As it becomes oxygenated it tends to turn brown or yellow because of the presence of Iron salts in solution and in suspension. It can usually contain both dissolved and suspended material. 

Traditional treatment way
In general, proper treatment of landfill leachate is difficult for its refractory contaminants and widely variant volume due to irregular rainfall. Therefore various advanced physicochemical treatment processes have been developed. These processes are mainly composed of biological and physicochemical processes and they are very effective and economical in the early stage of landfill. But as landfill ages, the characteristics of landfill leachate changes to have lower biodegradable organic matters and highly concentrated nitrogenous compounds. In this case biological oxidation of organic compounds and denitrification of nitrogenous compounds become hardly functioned. 

FCM Flat Ceramic membrane for landfill leachate treatment
To solve problems of lower biodegradable due to the landfill ageing, we used the integrated FCM ceramic membrane process to remove microorganism with long age and adopted both MBR to enhance the removal efficiency of biodegradable organic matters and nitrification rate. As the result, the effluent water quality met the enhanced regulation limits and continual public complaint was resolved.
