Water Production Procedures
Comprised of 3 procedures; clarification, filtration and disinfection. Key and supporting production processes are as follows:
Once the chemical-added raw water has been mixed in the tank, it will be transferred into the clarifier, by getting through the tri-dent and them down to the bottom of the tank and eventually lifted to the top. Clear water at the uppermost will overflow into the gutter through to the filter. Meanwhile, sediment, once gathered together, will form sludge, will be drained out to the sediment removal system. Water processed from the clarification system will then be transferred into the production process again, while sludge cake will be disposed of in the designated area.
