Filtration for Mining Process Water & Heavy Industry
Mining and primary-metals operations move enormous volumes of process water at high solids loading. Blast furnace cooling, slag granulation, dust scrubbing, and tailings water all demand filtration that can run continuously on heavy, abrasive streams without packing up on consumable media.
K Factor pressure backwash filters are engineered for these duty cycles — high flow, high solids, continuous self-cleaning, and built for the ambient and operating realities of the mine site.
The filtration challenges in this industry
Abrasive solids loading
Mining process water carries abrasive mineral solids that wear out conventional filter elements quickly and clog cartridges within hours.
Blast-furnace cooling protection
Cooling water for blast furnace shells and tuyeres has to stay clean — fouling here threatens production rate and equipment life.
Dust scrubber blowdown
Wet scrubbing for dust control concentrates fine solids into a blowdown stream that has to be filtered before reuse or discharge.
Site logistics & uptime
Remote sites can't tolerate filter swap windows or consumable resupply schedules; equipment has to run continuously between major shutdowns.
How K Factor solves them
K-Optifil® for high-flow process water
Sized for high GPM duty with automatic backwash — no consumable media, no manual basket pulls, continuous self-cleaning.
Inline strainers for coarse protection
Coarse-solid removal protects downstream filters and pumps from oversized material in process and cooling streams.
Heavy-duty material selection
Materials and elements specified to handle abrasive load and the operating temperature of furnace and process water systems.
Engineered site packages
Skid-built packages delivered ready for installation at remote sites, with controls and piping pre-fabricated.

Frequently asked questions
What is the best filter for mining process water?
A heavy-duty automatic backwash pressure filter (K-Optifil) sized for high GPM duty is the standard solution for mining process water. It handles abrasive mineral solids continuously without consumable media and without manual basket pulls — critical at remote sites where filter swap windows aren't acceptable.
How do you protect blast furnace cooling water?
Continuous automatic backwash filtration on the cooling loop maintains heat-transfer surfaces and protects tuyeres and shell-cooling channels from fouling. Element specification and material selection are matched to the operating temperature and solids load of the furnace water.
How do you filter dust scrubber blowdown?
Wet scrubbing concentrates fly ash and reaction-product solids into a high-load blowdown stream that quickly plugs cartridges. A heavy-duty backwash filter with abrasion-resistant elements handles this duty continuously and enables reuse of the scrubber water.
How abrasive a stream can you handle?
Element specification, vessel lining, and material selection are matched to abrasive load on every project. We've installed in tailings, slag, and dust-blowdown duty.
Do you build for remote sites?
Yes — skid packages ship complete with controls, instrumentation, and piping ready for connection on arrival.
