10 year anniversary in 2017 since the delivery of 3 Krone Bernoulli units 24” KAF. The King Abdullah University of Science and Technology (KAUST) in Thuwal, north of Jeddah in Saudi Arabia, required a desalination RO based technology plant for the university buildings and its accommodation. The plant was designed with a capacity of 40,000m3/day with the facility to increase to 50,000m3/day in the future, as and when required.
The huge advantage of Krone KAF self cleaning auto Bernoulli filters was that they can work without pumps in front – just with the water column pressure of the red sea level! Only 0.2 bar is sufficient to run the KAF filters in fully automatic mode.
Operationally, water is abstracted by pipeline form the Red Sea and filtered by 3 KAF 24” Krone Filter Solutions Bernoulli filter units and then pumped through 4 Superflux filters, prior to being processed through cartridge filters and the four Sea Water Reverse Osmosis (SWRO) units. Energy recovery is achieved using Pelton turbines thus reducing the energy consumption of the Reverse Osmosis (RO) plant. The treated water from the first stage is used as potable water for the university and irrigation water on the site. A further second pass Brackish Reverse Osmosis (BRO) system is included to produce water for the central utility cooling system.
