Water Treatment for Power Generation: In January of 2016 Quantum Filtration Medium conducted a series of site visits to assess the options for upgrading the water treatment plant supplying water to the Kuala Langat Power Plant (KLPP). The goal was to highlight low cost options with a low impact on plant serviceability to increase the plant performance, efficiency and reliability, and ability to better cope with the seasonal load changes experienced in the raw water supply.
The operation of KLPP has begun since 1996 using combined cycle gas turbine and the plant is currently contributing 675MW of electricity generation capacity to the grid. The ability of the plant to supply electricity to the grid according to its obligation under the Power Purchase Agreement depends on a number of factors including reliable clean water supply for the purpose of cooling. On average, KLPP draws 20,000 cubic meters of treated water for its daily operation. For optimal operation and life of the plant, the water needs to be as clean as possible with low content of organic or inorganic substance that would impact the plant operation.
There are four mains areas of the plant where the potential for considerable improvements were identified.
• The possibility of adding bore water to the raw water supply
• Clarification of the raw water before entering the plant
• Optimisation of the flocculent/polymer dosing program (inc. type and dosing rate)
• Changing of the media in the rapid sand filters to DMI65®
