This is an illustrative scenario showing how Reynolds & Bauhm equipment can be configured for this application. Every site has unique requirements — contact us for a solution tailored to your specific seawater and demand.
A remote coastal site with no reliable freshwater supply needs ~72 m³/day of potable water from an open seawater intake at 35,000 mg/L TDS. The intake carries seasonal algae, oil and suspended solids that would foul membranes within weeks. The whole plant has to ship in a container, run on a generator, and produce drinking-quality water with the lowest practical energy per cubic metre.
Step-by-step configuration from raw seawater intake to potable storage.
Seawater is screened to protect the downstream plant. Feed pump lifts to the DAF at a controlled rate.
Coagulation and dissolved-air flotation remove algae, oil and suspended solids — the membrane-protection barrier that holds a low SDI even through a bloom.
Final particulate polish ahead of the high-pressure pump, protecting the membranes from any carry-over.
Six 8040 SWRO elements at 60 bar produce permeate at 45% recovery. A PX pressure exchanger recovers energy from the concentrate, cutting specific energy to ~3.4 kWh/m³.
Permeate is remineralised and pH-trimmed to potable spec, then sent to the product tank. Online conductivity confirms quality continuously.
The critical equipment that defines performance — sized for the duty, not the full bill of materials.
High-rate flotation with 5.5 bar air saturator and oil-free compressor — algae, oil and solids removal.
