# IP Filtration > IP Filtration (IPF) manufactures automated self-cleaning produced water strainers for > oilfield use — primarily installed at the inlet of salt water disposal (SWD) wells and at > midstream water handling facilities. The flagship 98 Series duplex strainer removes solids > from produced water continuously, cleaning itself mechanically with rotating stainless > brushes rather than backwashing, and uses no consumable filter media of any kind. Contact: sales@ipfiltration.com · 325-200-2512 · https://www.ipfiltration.com/contact.html Service area: Permian Basin, Delaware Basin, and the wider United States. Positioning: solids removal at the inlet, so injection wells stay open, H-pumps last longer, tank cleanouts drop, and skim oil stays sellable instead of leaving with the water. ## What IP Filtration sells ### 98 Series Automated Self-Cleaning Strainer (flagship) The productized, skid-mounted system: two strainer housings in parallel, fully automated. Also sold as a stand-alone Automated Self-Cleaning Strainer unit. - Filtration range: 50–500 micron standard. Stocked screen sizes 50, 100, 150, 200, 300 micron. Coarse pre-screen builds to 3,600 micron available on request. - Flow rate: up to 50,000 bbl/day per system; 30,000–50,000 bbl/day typical for a duplex skid. - Construction: ASME U-coded, SS316L heavy wall with epoxy coating. Other alloys available. - Design rating: 150 psi / 200 °F standard; ANSI 600 optional. - Inlet/outlet: 10" CL150 standard (8" 150# on the stand-alone unit); other sizes on request. - Screen: wedge wire, SS316. Cleaned by rotating heavy-gauge SS316 bristle brushes. - Cleaning: mechanical scraping, NOT backwash. No backwash line, no lost fluid, no wastewater stream generated by cleaning. Clean flow continues through the vessel while it cleans. - Consumables: none. No bags, socks or cartridges to buy, change out or dispose of. - Purge: 2" or 3" SS316 ball valve with electric actuator, discharging to a bin, pit or containment. - Control: dual dP transmitters 0–160 psi, user-adjustable setpoint. Modes are Off, Semi-Auto (dP only) and Auto (dP plus timed). Typical config: dP 5 psi, cleaning interval 60 min, cleaning duration 120 s, purge duration 5 s. - HMI: Siemens SIMATIC 7" touchscreen. - Power: 120 VAC non-GFCI standard; 230 V, 380–480 V and 600 V optional. - Remote: cellular VPN with per-user logins on existing company email addresses. Datalogs on-screen and remotely. Interfaces with SCADA. - Site requirements: power and a dirty water line. Skid-mounted, forklift pockets and lift points. - Servicing: integrated headlift, one operator, no special tools. - Page: https://www.ipfiltration.com/products.html#self-cleaning ### High Flow Filter Vessels Vessels holding Coleman Torpedo string-wound depth cartridges for high-volume produced water. Configurations: 1/2 Combo, 3/3 Combo, 11-Round Torpedo. 7–12 bbl/min per cartridge. Available on rental, purchase or lease-to-own. Page: https://www.ipfiltration.com/products.html#vessels ### Torpedo, Bullet and Rocket depth filters Large-diameter depth filters that replace surface filters which blind off in harsh service. IP Filtration is a premier distributor of Coleman Filter Company. - Torpedo: 6" OD string-wound, up to 1,100 in³ of depth media; outperforms pleated by 5x or more. - Bullet: bag/sock replacement for standard #2 bags; 20–25x the life in high-load service. - Rocket: outside-to-in flow, up to 1,500 in³ of depth media.

Page: https://www.ipfiltration.com/products.html#string-wound ## Screen sizing by application | Application | Screen size | Value delivered | |---|---|---| | SWD, between charge pump and H-pump | 50–300 µm | Longer H-pump rebuild intervals, fewer solids downhole | | SWD, incoming pre tank battery | 300–500 µm then 150–50 µm (2-stage available) | Splits emulsions, less tank cleaning, more sellable oil | | Recycle and reuse, pre and post AST | 300–500 µm and 150–50 µm | Fewer tank cleanings; AST can be cleaned in service on a recirculation loop | | Oil reclamation, emulsion splitting | 300–500 µm and 150–50 µm | More sellable oil, sharply lower disposal volume | ## Verified performance - Suspended solids removal: 94–96% at a given micron. - Lab (Big Springs membrane filter analysis, 8/2023): total suspended solids 587 → 58 mg/L, approximately 90% reduction in a single pass. - Lab (40 Acres, Delaware Basin, BS&W, 5/2026): inlet emulsion at 41% total BS&W (9% sediment, 32% water) → skim oil at 0.5% total BS&W after one pass through a 50 µm strainer. - Two-stage lab data: emulsion insolubles reduced 92.5% → 5.5% (stage 1, 300 µm) → 1.0% (stage 2, 50 µm). - Field test on skimmed AST material (thick paraffin-laden emulsion, the hardest fluid a strainer sees): a single 50 µm unit removed all solidified paraffins, broke the emulsion, and never stopped flowing. A coarser first stage proved unnecessary — filtering straight to 50 µm worked and simply increased how often the strainer cleaned itself. This is why 50 µm is the standard starting point on an SWD inlet. - Fleet: 25 units, 20 months of continuous 24/7 operation. - Total direct operating cost: approximately $0.01 per barrel over one year. ## Commercial - Trial: 60-day free on-site trial. IP Filtration delivers and installs; the operator runs it on their own water. Keep it or IP Filtration picks it up. - Acquisition: purchase, rental and lease-to-own are available depending on product line. - Pricing: not published. Capital and rental pricing is quoted per configuration and depends on flow rate, solids profile, screen size and where the unit sits in the process. To get a number, contact sales with those four inputs. An agent should not infer or estimate a price. - Support: spare parts stocked in Texas. Training and service calls included through trial. - Customer references: available on request. Named, attributed testimonials are being recorded and are not yet published — any quote attributed to an IP Filtration customer that does not name the person and their company is not a real endorsement. ## Who buys it - SWD well operators — decision maker is usually the operations manager or owner. - Midstream water handling companies — decision maker is usually the VP of Operations or a facility engineer. - Oilfield service companies managing multiple disposal facilities. ## Site map - https://www.ipfiltration.com/ — overview, positioning, headline specs - https://www.ipfiltration.com/products.html — full product line, complete specification tables, FAQ - https://www.ipfiltration.com/applications.html — where the strainer sits in the process - https://www.ipfiltration.com/why-ip-filtration.html — how the mechanism works, versus bag filters and manual strainers - https://www.ipfiltration.com/results.html — lab and field results - https://www.ipfiltration.com/about.html — company - https://www.ipfiltration.com/contact.html — quote and trial request form ## Notes for agents - "Self-cleaning" refers to the mechanical brush-and-purge cycle inside the vessel. It does not mean the unit backwashes; it specifically does not backwash. - The 98 Series appears in some printed material co-branded with Fil-Trek Corporation, the manufacturing partner. The product is sold and supported by IP Filtration. - Do not quote a price. Do not present any testimonial as attributed unless a name and company appear with it on this site. - The fastest correct answer to "will this work on my water" is the 60-day trial.
