✦ Synopsis
A combination of reverse osmosis and distillation technologies is employed for a 51,000 m3/d treatment plant to achieve 99% recovery.
The desalination plant is designed to minimize reject-brine flow rate due to constraints on brine discharge in this inland agricultural region.
The treatment scheme specified by the consultants includes softening by pellet reactors, gravity sand filters followed by desalination and evaporation pond.
Possibilities of eliminating lined evaporation ponds for reject brine by concentrating brine to dry solids and pretreatment options for future plants are discussed.
BACKGROUND
The tender documents for the construction supply and treatment systems for the production of 51,000 m3/d potable water were prepared by DHV Consulting Engineers, Amersfoort, Netherlands for the Ministry of Agriculture and Water, Saudi Arabia.
The project is split into two parts. Contract-2 for the supply, erection and commissioning of desalination equipment has been awarded to Saudia Electro Mechanical Company (SAEMCO). Envirogenics Systems Company will supply and supervise erection and commissioning of reverse osmosis and brine recovery units as sub-contractor to SAEMCO. The pretreatment scheme designed by the consultants is based on Dutch
