The Project is for the design, supply of a seawater treatment plant sized for 245,300 BPD (39,000 m3/day) of low sulphate water.
The Project scope consists of a single lift module arrangement comprising: Coarse Inlet Strainers, HP Feed Pumps, Guard Cartridge Filtration, Sulphate Removal Membrane System, Gas Strip Deaerator, Chemical Cleaning System, Chemical Dosing Systems, Control Valves and Instrumentation.
Fine filtration is achieved by a set of cartridge filters to provide fine filtration down to 5µm prior to membrane trains. The set of cartridge filters supplies feed water for six (6) trains.
The conditioned water, boosted to the required feed pressure, enters the Sulphate removal trains. Each membrane train is fitted with pressure vessels containing SR90-400 nanofiltration elements.A recovery of 75% is achieved by a 2:1 brine staged configuration. Brine reject from the process is discharged overboard, while the low Sulphate permeate is routed to the gas strip deaerator. A dedicated clean in place (CIP) package, consisting of cleaning tank, pump, heater and cartridge filter vessel is provided for membrane cleaning purposes.
