System Description

• Primary Screening takes place in the bar screen strainer
• Separation of Oil and Grease
• Activated Sludge Biological Treatment essentially involves bringing the water to be purified into contact with a bacterial floc in the presence of oxygen (aeration).
  
• The system includes air blowers and diffusers placed on the bottom of the aeration tank, which direct the air flow into the waste-water to dismantle the organic load.
• Solid-Liquid Separation and Clarification takes place in the SOLIQUATOR
  
• On-Line Liquid Polymer Grade Preparation and Injection is performed by an ODIS PP series on-line polymer preparation device - an automatic unit specially designed to ensure continuous preparation and injection of the polymer solution.
• Return of Activated Sludge to Aeration Pools - the stage at which activated sludge that has settled in the SOLIQUATOR is returned to the aeration pools.
• Multi-media Depth Filtration is performed by an array of multi-media filters with a high-depth media bed for final effluent polish at a relatively low filtration rate. Effluent water quality acceptable for unlimited irrigation.
• Disinfection involves the injection of hypochlorite in order to remove all pathogenic microorganisms from the treated water. The disinfecting unit is fully automatic and controlled by residual chlorine controller.
