Geiger® Seawater Intake Equipment KPONE, Ghana

In 2016 KPONE Independent Thermal Power Station (CCGT) was constructed to improve the distribution of electricity throughout the country. The power plant is a 340 MW (460,000hp) multi-fuel-fired thermal power station. At KPONE, seawater accessed through underground pipes is used to feed the power plant’s cooling water system.

For the first stage in the mechanical screening of seawater (coarse screening), the efficient and robust Geiger^® Cable-Operated Bar Screen Cleaner was implemented, and for the second (fine screening) the innovative, compact and low-maintenance Geiger MultiDisc^® filtration machine. A Geiger^®Impressed Current Cathodic Corrosion Protection System protects the screening equipment in aggressive mediums i.e. seawater.
