Self-Cleaning Strainers — Ain Dar SRF Plant
Automatic self-cleaning strainers added upstream of the Ain Dar sulfate-removal plant’s cartridge filters, ending the high frequency of cartridge replacement on the 92,000 m³/day seawater intake.
Automatic self-cleaning strainers for the seawater pre-filtration system of the Sulphate Removal Plant, eliminating the heavy cartridge-filter replacement downtime. Two-stage 100 µm + 50 µm filtration with SS-316 sintered screens and a special seawater-duty coating.
IE-Consult reviewed the recurring cartridge-filter (CF) issue and proposed a four-train SCS — each train a 100-micron stage followed by a 50-micron stage — to protect and extend CF life. FK & Partner Co. selected, supplied, fabricated piping, and commissioned on site.
The seawater pre-filtration system (basket strainer + 10- and 5-micron cartridge filters) suffered a high frequency of cartridge replacement, driving cost and downtime on a 92,000 m³/day intake.
- Frequent, costly cartridge-filter replacement
- Corrosive seawater duty
- High flow — 92,000 m³/day
A treatment train sequenced to the contaminants.
Four SCS trains with SS-316 multi-layered sintered screens (100 µm then 50 µm), fully coated for seawater duty, with a microprocessor differential-pressure controller triggering automatic backwash — removing manual CF changeouts.
