Our oil-water separation filter paper is a high-performance filtration media engineered for efficient separation of oil from water in demanding industrial environments. Designed with advanced hydrophobic and oleophilic properties, this specialized filter paper selectively absorbs oils and hydrocarbons while repelling water, ensuring superior phase separation without compromising flow rates. Ideal for applications requiring precise emulsion breaking and contaminant removal, our oil-water separation filter paper delivers exceptional clarity in effluent streams, meeting stringent environmental regulations such as those from the EPA and EU Water Framework Directive.
Crafted from premium cellulose fibers treated with proprietary silicone-based coatings, the filter paper exhibits remarkable durability and chemical resistance. It effectively handles a wide range of oils, including crude, lubricants, hydraulic fluids, and petroleum derivatives, achieving separation efficiencies exceeding 99% under optimal conditions. Available in various grades for coarse to fine filtration, this product supports high-throughput operations in continuous processes, reducing downtime and operational costs. Whether used in gravity-fed systems, pressure filters, or coalescing units, our oil-water separation filter paper provides reliable performance, safeguarding equipment and protecting ecosystems from oily pollutants.
With a focus on sustainability, our filter paper is biodegradable where applicable and optimized for incineration or recycling, minimizing waste disposal challenges. Trusted by global leaders in oil & gas, manufacturing, and wastewater management, this solution represents the pinnacle of filtration technology for oil-water separation challenges.

The versatility of our oil-water separation filter paper makes it indispensable across multiple industries. In the oil and gas sector, it excels in produced water treatment, separating crude oil emulsions from brine during upstream operations. Refineries deploy it in wastewater polishing stages to remove free and emulsified oils before discharge, complying with zero-discharge mandates.
Manufacturing facilities, particularly metalworking and machining shops, utilize the filter paper in coolant recycling systems. It efficiently recovers tramp oils from water-based cutting fluids, extending coolant life and reducing disposal volumes. In the automotive industry, it's integral to parts washing stations, ensuring rinse water is oil-free for reuse.
Environmental remediation projects benefit from its deployment in spill response kits and stormwater treatment. Power plants and steel mills apply it for bilge water purification and sump drainage, preventing oily contaminants from entering sewers. Food processing plants use select grades for edible oil/water separation in processing byproducts, adhering to HACCP standards.
Additionally, marine applications include bilge water separators on ships, where compact filter paper modules meet IMO regulations. Laboratories and research facilities rely on it for analytical sample preparation, guaranteeing interference-free oil-water splits in emulsion studies.

Q: What makes your oil-water separation filter paper different from standard filter paper?
A: Unlike standard papers, ours features dual hydrophobic-oleophilic treatment for selective oil absorption, preventing water saturation and enabling true phase separation.
Q: Can it handle emulsified oils?
A: Yes, high-capacity grades break stable emulsions through coalescence promotion, achieving >99% removal in most cases; preconditioning may enhance results for tight emulsions.
Q: What is the shelf life?
A: Up to 3 years when stored in dry, cool conditions away from direct sunlight, with no degradation in performance.
Q: Is it suitable for high-temperature applications?
A: Standard grades handle up to 120°C; for higher temps, consult our engineering team for specialized variants.
Q: How do I dispose of used filter paper?
A: Saturate oils can be incinerated as hazardous waste or de-oiled via pressing for recycling; complies with most local regulations.
Q: Do you offer samples?
A: Yes, free samples available for qualified B2B inquiries to test in your system.
Q: What particle retention does it provide?
A: Primarily for oil droplets >20 μm; pair with pre-filters for finer solids if needed.
