Optimisation of existing water treatment plant

An existing 300 m3/d treatment system that had been in place for many years was not performing to site requirements. The plant was old and no documentation was available. The personnel with the required skills had left the organisation. The client was at risk of not be able to maintain drinking water quality.

Alpha Concepts solution involved:

• a process analysis to determine the optimum operating condition for each unit operation
•  setting the plant to perform as required
•  the development of detailed Operational and Maintenance documentation
• site personnel training in  plant operation and maintenance

The key unit operations involved were:

• upflow bed clarification
• media filtration
• powdered activated carbon treatment
• coagulant addition and control
• disinfection
• reservoir water storage management and control
