UGL was contracted by Alstom to build a world-class water treatment system for the Kaeng Khoi 2 Power Plant which is located in the Saraburi province of Bangkok, Thailand. Their gas-fired thermal power plant had a generating capacity of 1468 megawatts which totals for 7.5% of Thailand’s total power.
The problem Alstom needed to be addressed was finding a consistent, reliable source of water for the cooling tower that would be cost effective and sustainable. They also needed a wastewater treatment solution to refine raw cooling water which would also require softening or removal of solids in the water. By providing a solution, properly treated water has the potential of scaling down power in the cooling towers.
Additionally, the project called for a solution for treating effluent-steam generated from the purge of flue-gas desulfurization scrubbers to reduce the impact on the environment. The challenge that this poses is that wastewater can be hard to process as it contains heavy metals, suspended solids and salts like magnesium, calcium and sodium chloride.
The UGL Solution
UGL was able to deliver a solution that consisted of three key elements that included a pre-treatment plant, a demineralization plant and a wastewater plant. These three elements play an integral role in reducing the impact on the environment and providing the Kaeng Khoi 2 Power Plant with a consistent flow of water. The pre-treatment plant produces softened clarified water for the cooling tower. From there, the demineralization plant further treats the water for the boiler system. In the final stage, UGL constructed a wastewater plant of two units of dissolved air flotation where each can handle the treatment of 315 cubic meters an hour of refined wastewater.
With the solution, Kaeng Khoi 2 Power Plant was able to increase system reliability, able to generate the max amount of electricity and reduce the environmental impact. UGL delivered a cost-effective solution that has long-term reliability!
