Tokyo, Japan, Aug 19, 2005 - (JCNN) - Matsushita Ecology Systems and Matsushita Environment & Air-conditioning Engineering have developed a system to use supersonic to reduce surplus sludges by 70-80% compared to conventional systems, as announced on August 18. Complaints associated with land-applied sewage sludges primarily involve irritation of the skin, mucous membranes, and the respiratory tract accompanied by opportunistic infections. In addition, steel and iron mill sludges which have become a large waste disposal problem in the steel industry, have been successfully agglomerated through a process of pressure agglomeration. |
