FEED stands for Front End Engineering & Design and is a critical stage of any project,
absorbing the engineering services provider know-how. It contains full information on the equipment
ordering and defines the exact scope of the next stage - detail mechanical, electrical, instrumentation and control design.
FEED substantiates the plant guaranteed functionality and reliability, the project timetable and the budget and
substantially decreases the project risks and contingencies.
Having the FEED package, any engineering company without previous desalination experience may execute the project of any size.
All these SWRO desalination projects (6,000 - 250,000 m3/day) are of multiple train design; the size of each train being defined by the capacity of the SWRO process driver – the high pressure feed pump. So the S1800 project is for Seawater desalination and built around the 1800 m3/h pump.
S2800 (250,000 m3/day)
This SWRO plant is the biggest in our collection and the most sophisticated in design.
It has very tight layout hydraulically optimized. For this plant size single-stage multi-media filtration
with the backwash tank has little advantages compared to the forced backwash with the high-capacity pumps.
S1800 (85,000 m3/day)
The pretreatment includes lamella clarifier and dual media filtration. The permeate produced in the 3-stage reverse
is re-mineralized in the limestone reactors. Single-stage filtration is typical for the SWRO plants operating in
Israel and Spain.
S1000 (96,000 m3/day)
The pretreatment includes two-stage pressure filters. Milk of lime is dosed to the permeate produced in a
single-pass SWRO process.
This process is typical for the SWRO plants under operation in Spain, Chile, India, Singapore, and Saudi Arabia.
S1001 (150,000 m3/day)
The plant includes an intake pumping station, lamella settler, DAF, UF and a single stage reverse osmosis.
These processes chain and the plant size are quite similar to the ones requested by the tender of
Chennai Metro Water Supply company (November, 2016, Nemmeli, India).
S750 (72,000 m3/day)
The plant includes DAF, lamella, DMF & UF and a 3-stage reverse osmosis. The DMF & UF tandem
has been used in a number of projects: Kindasa (2006, 2009, Saudi Arabia), London (2008, Great Britain),
Busan Gijang (2011, Korea), Codelco (2015, Chile).
S300 (21,000 m3/day)
S80 (6,000 m3/day)
