Commercial Submerged Aeration Filtration, (SAF), Wastewater Treatment Plant

Application and Benefits

Application

Submerged Aerated Filtration Wastewater Treatment Plants are advanced wastewater treatment solutions for treating domestic and commercial sewage, where the treated effluent produced by the treatment process is suitable for disposal to ground, through land application.

Submerged Aerated Filtration Wastewater treatment technology offers a robust, cost effective wastewater treatment process that is suited for all community applications.

The Submerged Aerated Filtration treatment process does not require a high level of technical support to operate correctly. If you require something that is reliable, requiring minimal operator input, this is the “go to” technology.

The CMWEL range of SAF Wastewater Treatment Plants are designed for commercial applications.

Typical applications are for small communities, such as villages, schools, maraes, camping grounds, etc.; where it is required to provide a local wastewater treatment facility to treat and safely dispose of the wastewater produced by that community.

Benefits

CMWEL designs are based on 23KL Concrete, or 25KL & 30KL PE water tanks, which allow for:

  1. Open ended design, allowing the wastewater treatment plant solution to be sized for each individual application.
    Allows for easy future design modifications, to cater for future flow, and/or raw wastewater strength changes.
  2. Tank selection to suit buried, (concrete), partially buried, (concrete or PE) and restricted heavy load access applications, (PE).
  3. Sealed tanks allowing for the carbon filter treatment of odious gas and spent air discharges to atmosphere.

Commercial Submerged Aeration Filtration: System Specifications

Tanks

  1. Concrete: 60KPA, (minimum), concrete with microsilica addition to the concrete to make it moreresistant to chemical attack.
  2. PE: Insulated PE Water Tanks used for the SAF Process Tanks.
  3. Fully Automatic.

PLC controller with audible, visual and optional remote alarm facilities.
