Integrated Filtration & Scale Control for Produced Water, Injection & Jet-Pump Systems
Upstream produced water carries sand, scale, iron sulfide, and corrosion product. Water injection requires tight particulate control to protect formation permeability and sweep efficiency. Jet-pump motive water has to stay clean and scale-free to avoid nozzle and venturi erosion that throttles production. Refinery and petrochemical streams face continuous sediment, biological loading, and pipeline corrosion product reaching critical equipment.
K Factor's integrated solution — Lenzing CakeFil precoat filtration paired with MHD FlowMAG magnetic scale mitigation — replaces complex 4-stage conventional trains with a single, fully automated skid. Stable ~2 µm effluent, no chemical antiscalant dosing, no cartridge changes, and a footprint sized for offshore and constrained brownfield sites.
The filtration challenges in this industry
High solids in produced water
Sand, scale fragments, iron sulfide, and formation fines blind cartridge filters within days and erode jet-pump nozzles and venturis — directly throttling production and forcing constant manual intervention.
Scale & MIC in injection water
CaCO₃, BaSO₄, and MgCO₃ scaling, plus microbial-induced corrosion, plug downhole formations, drive up antiscalant chemical spend, and trigger expensive injection-well workovers averaging $500K–$2M per well.
High CAPEX & footprint of 4-stage trains
Conventional multi-vessel filtration trains with disposable cartridges and chemical dosing skids demand large plot space, heavy capital outlay (~$2.5M typical), and complex piping that brownfield and offshore sites simply do not have.
Low availability & high OPEX
Cartridge changeouts, manual cleaning of strainers, antiscalant dosing programs, and pipeline pigging events erode uptime and consume OPEX — on remote wellsites and offshore platforms the cost of every shutdown is multiplied.
How K Factor solves them
Lenzing CakeFil precoat filtration
Single-stage tubular pressure filter with self-cleaning precoat technology delivers stable ~2 µm effluent on highly variable produced-water solids loading — replacing 4-stage conventional trains with one automated skid. Slurry or dry-cake discharge depending on site logistics.
MHD FlowMAG magnetic scale mitigation
Patented multi-pole magnetic conditioning prevents CaCO₃, BaSO₄, and asphaltene deposits in injection lines, oil transport pipelines, and jet-pump motive water. Zero power, zero chemical dosing, and zero consumables — proven on Total Energies, ADNOC, and Kuwaiti operations with up to 35% asphaltene reduction.
Jet-pump motive-water protection
Clean, low-solids, scale-controlled motive water at ~2 µm prevents nozzle and venturi erosion, sustains lift performance, and extends overhaul intervals on jet-pump artificial-lift systems.
Fully automated 24/7 operation
Automated backwash, precoat regeneration, and slurry/dry-cake discharge sequences run unattended. No manual filter cartridge changes, no operator-driven cleaning cycles, no antiscalant batch dosing — compatible with remote wellsite and offshore minimum-manning operations.
Compact skid for constrained sites
Drastically reduced footprint vs conventional multi-vessel trains. 316L SS standard; Duplex and Super Duplex available for high-chloride produced water and Gulf chemistry. Pressure ratings to 20 bar standard, higher for wellhead service.
Quantified CAPEX & OPEX savings
Typical CAPEX drops from ~$2.5M to ~$0.95M per train — a >60% reduction. OPEX falls in parallel through eliminated cartridge spend, eliminated antiscalant dosing, fewer pigging events, and dramatically reduced operator labour.

Frequently asked questions
How does K Factor's integrated CakeFil + FlowMAG system reduce CAPEX vs a conventional 4-stage train?
A conventional produced-water injection train uses four discrete stages — coarse strainer, multimedia filter, cartridge fine filter, and antiscalant dosing skid — with associated piping, instrumentation, and plot space. K Factor's integrated solution collapses that into a single CakeFil precoat skid plus an inline FlowMAG magnetic conditioner. Typical CAPEX drops from approximately $2.5M to $0.95M per train (>60% reduction), with proportional cuts to footprint and installation cost.
How do you protect jet pumps from nozzle and venturi erosion?
Jet pumps require clean, low-solids, scale-controlled motive water to avoid erosion of the nozzle and venturi geometry that drives lift performance. CakeFil precoat filtration delivers stable ~2 µm effluent on highly variable solids loading, and FlowMAG mitigates CaCO₃ and BaSO₄ scale formation downstream. Together they sustain jet-pump efficiency and extend overhaul intervals.
Can you eliminate antiscalant chemical dosing?
In many oilfield streams, yes. MHD FlowMAG's patented multi-pole magnetic conditioning prevents formation of CaCO₃, BaSO₄, MgCO₃, and asphaltene deposits without any chemical addition. Field references include Total Energies in the North Sea (significant asphaltene reduction) and Kuwaiti operations (up to 35% asphaltene precipitation reduction). Where some residual dosing is still required, dose rates drop substantially.
What is the best filter for produced water?
For high-solids produced water with sand, scale, and iron sulfide, the K Factor approach is CakeFil precoat filtration paired with FlowMAG magnetic conditioning and, where ferrous corrosion product dominates, an upstream K-Mag magnetic separator. The combination handles the full contamination profile continuously without disposable cartridges or antiscalant chemicals.
How do you meet water-injection particulate limits?
Continuous CakeFil filtration upstream of the injection pumps controls particulate to the level required to avoid formation plugging and preserve sweep efficiency — typically 2–10 µm absolute for sandstone formations and 5–25 µm for carbonate. Sizing and micron rating are matched to each field's injectivity specification.
How do you remove iron sulfide from oilfield water?
Inline magnetic separation (K-Mag) is the most effective capture mechanism for iron sulfide and ferromagnetic corrosion product, since iron sulfide rapidly blinds conventional filter media. Magnetic separation runs continuously and is purged on schedule without consumable spend, then handed off to CakeFil for residual fine solids.
Are your systems suitable for Gulf and offshore operating conditions?
Yes. K Factor has an active install base across the UAE, Saudi Arabia, and other Gulf markets, with Duplex and Super Duplex material options for high-chloride produced water. Skid footprints are engineered for offshore platform deck space and remote wellsite constraints, and controls are specified for minimum-manning operation.
Do you support API-aligned design?
Pressure vessels and skid packages are engineered to align with applicable API standards on a project-by-project basis, with full material traceability and ISO-certified manufacturing from our Hamilton, Ontario facility.
