Municipal Treatment Strategies

Considerations:

  1. Volume of daily flow
  2. Biochemical characteristics of the wastewater (including the organic strength) and the presence of any materials that are difficult to treat
  3. Proximity to a municipal treatment plant
  4. Regulations of the local health department and federal or state Environmental Protection Agency

Typical Solutions:

  1. A complete wastewater treatment system consisting of some or all of the following:

    a) A pretreatment device such as a Modulair flow equalization tank, a Lift-Rail grinder pump station or a Norweco comminutor
    b) An aerobic wastewater treatment plant such as a Modulair wastewater treatment plant for small to medium size flows or Travalair wastewater treatment plant for medium to large size flows
    c) A disinfection system such as a Bio-Dynamic tablet feeder prior to a contact tank

    d) Any one of a number of appurtenances designed to provide operational flexibility, aid in monitoring or reporting, or accomplish specific environmental protection goals

  2. A raw sewage pump station for higher volume flows, such as Lift-Rail or Posaprime, to move the raw wastewater to a municipal treatment plant or other remote location for treatment

Our treatment systems are designed in accordance with the guidelines set forth in RECOMMENDED STANDARDS FOR WASTEWATER FACILITIES, commonly known as "Ten State Standards."

System Description

Municipal systems treat domestic wastewater from a number of homes, businesses, schools or similar institutions along with small amounts of industrial wastewater from factories and industries.

Usually the volume and characteristics of the wastewater outside the domestic spectrum are regulated and controlled.

Typical flow volume ranges from 100,000 to hundreds of millions of GPD. Municipal systems usually have full-time operators who provide maintenance and monitor performance anywhere from weekly to several times per day.
