Produced- & Injection-Water Filtration in Oil & Gas
Produced water and seawater injection streams carry sand, scale, iron sulphide and oil-wetted solids. High-flow filtration removes the suspended-solids load that plugs formations and damages injection wells — and its high capacity cuts the change-out labour and footprint that matter most offshore.
The challenge in this industry
High solids & sand loading
Produced and injection water carry abrasive solids that damage pumps and plug the formation.
Injection-well & formation protection
Solids breakthrough reduces injectivity and can permanently impair the reservoir.
Offshore change-out labour & footprint
Deck space and manhours are scarce; fewer, higher-capacity elements reduce both.
Where it applies in an oil & gas water system
- Seawater injection-water prefiltration
- Produced-water polishing before reinjection
- Wellhead and injection-pump protection
- Prefiltration ahead of finer absolute or membrane filters
- Solids removal to protect downstream equipment
What high-flow filtration does here
High-flow elements remove suspended solids, sand and particulate to protect wells and equipment. They target solids — not dissolved constituents — and are typically staged ahead of any finer treatment.
Housing & elements from one source
We supply robust high-flow elements and a code-compliant vessel (316 or duplex, PED / ASME) from one source, built for the pressures and solids loading of injection service.

Frequently asked questions
Why high-flow for injection water offshore?
High-capacity elements handle heavy solids loading in far fewer housings, which is decisive where deck space and change-out manhours are limited.
Can the vessels be built to ASME or PED?
Yes. Injection-service vessels can be supplied to ASME VIII or PED 2014/68/EU (CE) with the appropriate material certification for the duty.
