Pre-Treatment Systems

Pre-treatment is a critical stage in desalination that protects downstream equipment—especially reverse osmosis membranes—from fouling and damage. This stage removes suspended solids, sand, organic matter, and microorganisms before high-pressure processing.

Centrifugal pumps circulate seawater through screening units, filters, and chemical dosing systems, ensuring effective conditioning of water prior to reverse osmosis. Reliable pre-treatment pumping improves membrane life, reduces maintenance costs, and enhances overall plant efficiency.

Pre-Treatment Processes Supported by Pumps

• Screening and filtration circulation
• Chemical dosing and mixing
• Transfer between pre-treatment units
