    Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

  • Reduce SBR Maintenance Costs With Jet Aeration

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

  • Primary Wastewater Treatment: Influent Monitoring

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  • An Ideal Aeration System For Aquaculture Corporations

    Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

  • Repair Or Rethink

    The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.
