Frequently Asked Questions

Desalination Components in Saudi Arabia — Common Questions

What membrane housing standards are accepted by SWCC and Saudi Aramco?

SWCC and Aramco typically require FRP housings manufactured to ASME RGP-DS-023 with hydrostatic test at 1.5× rated pressure, and end-cap O-rings in FDA-grade EPDM or Buna-N. Stainless 316L housings require EN 10204 3.1 material certificates and electropolished internals. Gulf Union Ozone supplies housings from manufacturers with active SWCC and Marafiq vendor lists, and can provide test reports on request.

Can you supply energy recovery devices for an existing SWRO plant?

Yes. We supply both isobaric pressure exchangers (compatible with ERI PX and Flowserve DWEER designs) and Pelton-wheel turbocharger units. Retrofit compatibility depends on the existing high-pressure pump and brine flow rates; our engineers will review the plant hydraulic data and confirm the best ERD option. Typical energy savings are 30–40% of specific energy consumption for seawater RO.

What chemical dosing skid options are available for Saudi desalination plants?

We supply antiscalant, biocide (non-oxidising and oxidising), chlorine (NaOCl or Cl₂ gas), and sodium bisulphite dechlorination skids as standard. Each skid includes calibrated metering pumps (PTFE diaphragm or peristaltic), HDPE or GRP day tanks, magnetic flow meters and a local control panel with ATEX option for classified areas. Skids ship pre-assembled and factory-tested from our Jeddah facility.
