Waste To Energy Water Sewage Sludge Drying MSW, Sludge, Manure Food Waste to Energy January 2011 Sewage Sludge Treatment Many wastewater treatment plants are coping with a waste stream of digested sludge. The sludge is normally dewatered by means of a centrifuge or belt filter press. After dewatering the sludge has a typical dry solids content of approx. 20 - 25%. Every country has a lot of problem with the fast increasing sludge, shortage of sewage treatment plant and limitation of landfill size. The volume is increased by 10%-20% every year by building up new sewage plant in every country. How can we treat these increasing sludge? We are not allowed to dump the sludge to sea. I think the best solution is to covert sludge to energy, which is possible when we dry sludge less than 10% water content and then possible to use sludge for the gasification and power generation which will be treated by Devolatization or gasification equipment. The dried sludge (Bio-Solid) can be applied as a fertilizer to improve and maintain productive soils and stimulate plant growth. They are also used to fertilize gardens and parks and reclaim mining sites. landfill with 4/1-5/1 reduction of volume, incineration, fuel for cement plant and etc.. also fertilizer depending upon heavy metal content.. etc.. means economic drying of around 80% sludge to dried sludge less than 10 % water content would be the key solution to save the world Here is the patented Microwave Near Infrared Ray System (MW-NIR).. drying any sludge, manure and waste food to 10%-0% humidity.. and also integrate with Devolatization or gasification system and power generation.. We can generate around 1 MW electric power and/or syngas from 100 tons per day 80% sludge.. or dried sludge can be used for landfill, fertilizer, bio-coal and etcwhich requires 1~2 million dollars of investment for complete drying system plus special filte
