A DEVICE TO TREAT FRESH WATER AND PROCESS SEWAGE CONTAINING FRESH WATER FOR GENERATING METHANE GAS USED AS A FUEL. TE SEWAGE BEING PROCESSED IN A PLASTIC SEPERATOR BARRIER BASED FLEXIBLE CHAMBER IN THE SEA, AND THEREBY PREVENTING BAD SMELL IN A COASTAL CITIES

摘要

A device, system, and method to treat fresh water and process sewage containg fresh water for generating methane gas used as a fuel through a plastic separator barrier based flexible chamber in the sea, and preventing bad smell in a coastal area are disclosed. In one embodiment, a device includes a digester chamber coupled to a sewage inlet channel ..made of plastic film separator to store a sewage containing fresh water, which is allowed to decompose releasing methane, the digester chamber is held by multi-chambered floats forming the upper periphery, a plastic sheet is used to cover the storage chamber to collect methane gas. Water treatment is carried out in floating plastic barrier based chambers on the sea held by floats and having filtration and sedimentation systems and using chemical treating agents like chlorine.
