Pre-treatment systems play a crucial role in Membrane Processes for seawater injection for offshore oil and gas production. Filtration, disinfection, chemical dosing, and coagulation are key processes used to remove contaminants, control microbial growth, prevent fouling, and enhance the reliability and efficiency of membrane systems. Implementing a reliable  pre-treatment systems and water quality intake ensures the performance and production of high-quality sea water for injection, protecting the reservoir against souring and scaling problems, avoiding squeezing operations and maximizing hydrocarbon recovery in offshore operations.

Ultrafiltration technology adds reliability to SRU pretreatment providing ultrafiltered water with superior quality than conventional filters and cartridges. Ultrafiltration membranes ensure the availability of the SRU by maintaining the operational campaign times and, in addition, increase their useful life. UF membrane can also be used alone to meet the stringent particle size specifications for seawater injection. The automatic backwash and cleaning system of the UF (CEB's) makes the injection less intensive in the operator's HH.
