El Arish is the largest city (with 114.900 inhabitants) lying on the Mediterranean coast of the Sinai peninsula, 344 kilometers north east of Cairo. It has a marina and many hotels.
El Arish is by a big valley called the Wadi el Arish, which receives water from much of north and central.
The North Sinai is a milestone for the Egyptian government planners to redistribute the high density population in the Delta, and it is expected that by accomplishing the irrigation and transportation projects, 3 million Egyptians will settle in North Sinai.
Traditionally, water has been supplied to the Government by low-yield wells, rain water collection, seawater desalination, and Nile water delivered by train, truck, and pipeline. For many years there has been interest in expanding the existing seawater desalination facility to provide a reliable supply of water for this area.
UNIHA uses the technology of reverse osmosis for the seawater desalination plant.
The raw water is taken from wells drilled in the shore area, so that the TDS of the raw water is similar to the seawater.
The plant consists of the following components:
- raw water storage tank
- feed water pumps
- media-filtration plant
- chemical dosing station to feed SBS and antiscalant
- cartridge filter with filtration degree of 5µm
- high pressure pumps coupled with energy recovery turbine
- RO skids
- treated water storage tank and booster pumps
The plant is completed with measuring and control instruments for fully automatic operation incl. control panels, PLC, power distributor and all related cabling.
The main accessory of the plant is washing and flushing station for automatic flushing after each shut-down and manual washing with the necessary chemical circulating pump, cartridge filter and the related piping.
