Shamassiya (Qassim, KSA), Brackish Water Reverse Osmosis Plant
Client Name: Ministry of Water and Electricity
Capacity: Basic design capacity 15,000 m3/day
System: UF Pre-Treatment System and Brackish Water Reverse Osmosis Plant

The process of treatment is based on reverse osmosis system with brackish water membranes with pretreatment by ultra-filtration membranes. The plant is designed to treat the well water having TDS of 2129 mg/l.

The treatment plant consists of 2 main RO blocks each of permeate output 6,825 m3/d. Permeate from the two RO blocks is then blended with ultra-filtered water to produce 15,000m3/d of treated water.  The recovery of the RO blocks is 85% and the recovery of the treatment plant with blending is 86.16%.

 

Objective of the treatment is to remove suspended solids and to bring down TDS, radioactive elements Radium Ra226+228 and Radon Rn222 and various other contaminants present in the well water, in order to make the water suitable for drinking as per WHO potable water standards.
