    Lyons, Michigan, pop.789, overcomes winter “ice cake” problem without having to raise and lower tank water level, ensuring full-strength water pressure and fire protection flow for residents.

  3. A Radical Solution: Lagoon Management Utilizing Natural Biological Processes
    10/24/2014

    The city of Davisboro is located in Washington County, Georgia. The 2012 census population was 1,793 at the 2013 census. The population includes Washington State Prison, approximately 1,500 prisoners.

  4. Top-Entry Agitators Keep Costs Low, Combat Pollution
    1/9/2014

    As the drainage basin to 85 million people, the Baltic Sea has faced considerable environmental strain for many years. Updated regulations to reduce levels of phosphorous and nitrogen prompted the Central Wastewater Treatment Plant in Saint Petersburg, Russia, to install new top-entry agitators in its aeration basins. By optimizing thrust and bulk flow, the updated plant now combats pollution by treating 400 MGD of wastewater while keeping energy costs to a minimum.

  5. Retrofitting Diffusers Saves Money, Increases Overall Plant Efficiency
    6/6/2013

    The village of Intercourse located in Leacock Township, PA was in need of a new wastewater treatment system. The system was to be efficient, reliable, and simple to operate and maintain. At the time, Sequencing Batch Reactor technology was emerging as an efficient and economical alternative to conventional flow-through systems.

  6. Mixing Comparison: Hydraulic Or Gas
    5/10/2012

    Fairfield-Suisun Sewer District (FSSD) in California installed a Vaughan Rotamix® hydraulic mixing system next to an identical anaerobic digester with a 7-year-old gas mixing system. Rotamix® installation was completed in Sept, 2010.

  7. Finding The Right Pretreatment Mix For RO/Ion Exchange Systems
    10/5/2011

    Smart defense benefits the entire team. Having an ffective, durable water pretreatment system in advance of reverse osmosis (RO) or ion exchange systems is the first, most critical line of defense ensuring smooth, more trouble-free performance downstream. Contributed By Eco-Tec

  8. Case Study: The Rehabilitation Of 43-Year-Old Waste Lagoons
    1/24/2011

    In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. By Dale Klussman

  9. The Principles Of Aeration And Mixing Utilizing Process Aerator Technology
    1/14/2011

    In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large consumer of both energy and operational costs. The Aire-O2 Triton aerator/mixer is a process aeration technology that addresses both of these aspects and is environmentally friendly, which is a winning formula to help achieve long term sustainability.
