The Clearstream Wastewater Treatment System is a highly efficient "extended aeration" sewage treatment plant. This system, through aeration and clarification, provides a proper environment for aerobic bacteria and other micro-organisms that convert the incoming sewage into clear, odorless, and organically stable water. Test results taken from actual in-service applications of Clearstream Systems average consistently below the United States Environmental Protection Agency requirements for direct discharge of treated effluent.
