A waste water treatment plant is designed to remove the pollutants present in the liquid portion of the flow. Waste water causes pollution by depleting dissolved oxygen in the receiving waters. The dissolved oxygen is required to sustain the aquatic flora and fauna that require oxygen to live. A waste water treatment plant has two objectives,

  • Treat waste water to desired standard
  • Retain sludge (solids) for subsequent periodic de-sludging.

It is important to note that a treatment plant must receive regular mechanical and process maintenance and de-sludging to ensure on-going compliance with the discharge licence, avoid pollution and ensure the maximum useful life of the plant.
