  • An Alternative Mathematical Model For Oxygen Transfer Evaluation In Clean Water
    An Alternative Mathematical Model For Oxygen Transfer Evaluation In Clean Water

    Energy consumption from aeration system is a biggest part of the total energy cost in wastewater treatment plant and account for as much as 60% of the energy consumption for the activated sludge process. Therefore, it is very important to know how effective the aeration system and significant attention has been paid to development and upgrade of standard method for quantifying oxygen transfer efficiency of the aeration system.

  • Monitoring ORP To Help Determine Arsenic In Private Wells
    Monitoring ORP To Help Determine Arsenic In Private Wells

    Arsenic is one of the most common elements in the earth’s crust and is commonly found in many locations at varying concentrations. The Midwestern United States has locations that are heavily laden with arsenic because of certain geological settings and conditions. This naturally-occurring arsenic can leach into groundwater potentially causing elevated levels of arsenic in drinking water supplies. The primary pathway that exposes arsenic to humans is through drinking water.

  • How To Fix High pH And Comply With The Clean Water Act
    How To Fix High pH And Comply With The Clean Water Act

    When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.

    Next Generation Mag Meter Measuring Flow In A Pump Station

    A municipal drinking water distribution system, also known as a water supply system, is used to provide fresh drinking water to residential and commercial customers and facilities around the world. A distribution system for drinking water typically begins with: a) intake of raw surface water from a reservoir or lake or b) ground water intake from wells transferred to a water treatment plant. During the water treatment process, the water intake must flow through a series of processes that clarify, filter, and disinfect the water source transported to the distribution system and made available for storage and human consumption.
