We have worldwide stock. In addition to our standard scope of supply, we also hold a large rental fleet of equipment. The Oilfield Division is known for it s problem solving. They provide filtration solutions and services for: Completion / Gravel pack fluids Workover fluids Water injection (water flood operations) Oily water clean-up Waste water treatment Chemical injection Pipeline flushing Produced water treatment (Sea) water intake filtration High pressure applications RO pre-filtration Drink water systems RO filtration Bilge water treatment Gas filtration WHY FILTRATION? Costs of environmental protection are key issues for oilfield operations. Efficiency, reliability and maximum performance are of the utmost importance. The main concern in oilfield filtration is to prevent reservoir damage. Many contaminants can plug off the reservoir / production zones during completion and water injection. Twin Filter will protect the reservoir from contaminants, including bacteria, scale, clay, rust, etc. Current environmental laws are becoming more stringent and are aiming for zero discharge. Many waste treatment technologies will not meet the discharge levels of the future. Twin Filter offers a solution for the removal of more than 99% of all hydrocarbons and emulsions from water streams. We design and manufacture filtration solutions for the oilfield and petrochemical industries, on - and offshore. Our field experienced engineers are constantly improving and designing equipment to handle new filtration solutions. AGENT, DISTRIBUTOR Twin Filter B.V.
