Description:

The seawater desalination equipment fit in container(20’ or 40’)exquisitely,not only conducive to transport,but also helps 

to field hoisting,placement abd rapid in use,the operation management has been greatly facilitate the equipment running.More 

important is to avoid the pipe,device installation,a large number of civil works; this will reduce investment cost,especially 

for remote areas,island regions.This set of equipment both fixed installation,mobile installation can also be applied to 

field operations and disaster relief emergency use.

SWRO System

SWRO Membrane System

he UF filtered water is fed into SWRO membranes using two pumps operated in series and a turbocharger-type Energy Recovery Device (ERD) in each train. The first pump is a VFD operated low pressure booster pump, which feeds water into a second high pressure pump. The HP pump further increases the water pressure and feeds the water through the ERD to reach the final pressure required for SWRO. The ERD transfers energy from the RO brine concentrate to the incoming feed water, reducing the energy required to perform the RO process.

Each SWRO train consists of dedicated feed pump (VFD operated), HP pump, startup control valve, ERD, RO pressure vessels, RO modules, and necessary valves and instruments. Each train is equipped with 36 nos. of pressure vessels, each containing 7 RO elements, having a total of 252 nos. of RO modules per train.

The control valve is installed after the discharge from HP pump for pressure control to ensure smooth startup of the SWRO system.
The SWRO train operation is fully automatic and each train runs independently to produce desalinated water. With the dedicated CIP arrangement, the trains can undergo chemical cleaning with a minimum of operator intervention.
