Ceramic MBR for Leachate Treatment

Storage site leakage is a liquid that leaks through a dump. This fluid may either be present in the storage area or may be generated when rainwater mixes with chemical waste. Modern storage spaces are often designed to prevent liquid from leaking out and entering the environment; however, if not properly managed, the leachate is at risk to mix with groundwater located near the site. This is free to discharge waste directly into groundwater in older landfills and leachate-free waste. In such cases, frequent leachate concentrations are often found in nearby springs and debris. As leachate first appears, it can be black, anoxic, and effervescent with dissolved and entrained gases. As it turns to oxygen, it tends to rotate brown or yellow due to the presence of Iron salts in solution and in suspension. It also rapidly develops a bacterial flora that contains significant growth of Sphaerotilus. Leakage from the storage area varies greatly in composition depending on the age of the storage area and the type of waste it contains. Generally it may contain both dissolved and suspended material. Leachate formation is mainly caused by rainfall leaking from waste accumulated in a landfill. When the solid is in contact with the separation of waste, it is called leakage if the leaking water becomes contaminated and then flows out of the waste material. An additional volume of leakage occurs during the decomposition of carbonaceous material, which produces a wide variety of materials including methane, carbon dioxide and a complex mixture of organic acids, aldehydes, alcohols and simple sugars.
