Aqseptence Group installed Geiger MultiDisc Travelling Band Screen for the Barka Greenfield Desalination Plant, Oman

As the largest seawater desalination plant in the Sultanate of Oman, Barka Desalination Plant – Phase 4 (Barka IWP) has installed the Innovative Geiger® Seawater Screening Equipment.

Challenge

The Barka Independent Water Project (IWP) Plant is a reverse osmosis desalination facility with a total of 281,000m3 per day of potable water output.
Before seawater is desalinated, it has to be mechanically cleaned of debris in order to protect pumps, condensers and other sensitive downstream equipment from clogging and other damage. Aqseptence Group’s Geiger®-branded two stage water intake screening system was chosen for this purpose.

Solution

For the first stage in the mechanical screening of seawater (coarse screening), the efficient and robust Geiger Cable-Operated Rake Cleaner was implemented, and for the second (fine screening) the innovative, compact and low-maintenance Geiger MultiDisc in order to protect pumps, condenser tubes and other critical equipment at the power plant. The total footprint of the plant could be reduced due to the compact Geiger MultiDisc® Travelling Band Screen.
