Aeration

  • A line of extended aeration type packaged sewage treatment plants manufactured by Demco Incorporated has been certified by the National Sanitation Foundation (NSF) for onshore and offshore use.

    Demco offers the plants in 18 sizes ranging in capacity from 325 to 12,500 gallons of sewage daily (from five to 400 persons, depending upon loading conditions) .

    NSF authorized use of its seal on Demco plants after careful evaluation of specifications, biological test data and a full engineering analysis comparing all sizes of units. In addition, vibration, shock, pressure and temperature range tests were successfully completed in accordance with U.S. Coast Guard regulation 33 CFR Part 159.15.

    The Demco plants are certified by the U.S. Coast Guard, and meet or exceed U.S. Geological Survey and anticipated IMCO effluent requirements.

    The plants treat all degradable wastes, including paper, grease, oil, detergents, garbage and human wastes.

    Sewage entering the plant is consumed by biological action in two aeration compartments prior to clarification and chlorination.

    The clear, odorless discharge contains less than 25 PPM biochemical oxygen demand and 50 PPM or less suspended solids.
