Water Treatment Plant

Cleartech designs water treatment plants that ensure to the treatment of the wastewater and make it usable.


Treatment for drinking water production involves the removal of contaminants from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, and minerals such as iron and manganese.

The processes involved in removing the contaminants include physical processes such as settling and filtration, chemical processes such as disinfection and coagulation and biological processes such as slow sand filtration.

Measures taken to ensure water quality not only relate to the treatment of the water, but to its conveyance and distribution after treatment. It is therefore common practice to keep residual disinfectants in the treated water to kill bacteriological contamination during distribution.

How does it work?
  • The first step in this water treatment plant is that the wastewater drains into the plant with the help of gravity through the main sewer system.
  • A mechanical stage then begins called the preliminary treatment or pre-treatment. In this stage, the water moves through the gravel chamber to remove any grit. The gravel is then disposed of at the dump. The water then moves to the bar screens which remove large objects. These are course screens. Next, the fine screens remove smaller objects such as undigested foods, matches, etc.
  • Similar to the gravel chamber, the grit chamber allows any grit in the wastewater to settle in the bottle. This is then removed from the tank and disposed of at the dump.
  • Next comes the sedimentation stage, also known as the primary treatment. In this stage, the water flows to the primary settling tanks, also known as pre-settling basins. These tanks have hoppers which are situated in the base of the tank where water flows through. This hopper moves around the edges which results in the treated water staying at the edges and the particulates in wastewater that contains the highest sedimentation are settled on the bottom of the tank.
  • The last step in wastewater treatment is inspection. This inspection involves checking the contamination level of the water treated and making sure it complies with the highest standards in order to be released or reused for domestic or industrial purposes.
