Automatic Backwash Filtration for Mining and Heavy Industry
Mining and heavy industry generate process water challenges that would defeat conventional filtration systems within days: high suspended solids from ore processing, abrasive mineral particles that destroy manual filter elements, scaling water chemistry from mine drainage, and continuous 24/7 operating demands that make scheduled shutdowns for filter maintenance unacceptable.
K Factor automatic backwash pressure filtration systems are configured for the abrasion resistance, solids handling capacity, and continuous operation requirements of mining and heavy industrial applications — serving mines and heavy manufacturing facilities across Canada, the United States, Australia, Chile, and the Gulf.
Mining process water filtration
Open-pit mines, underground mines, and ore processing facilities use large volumes of water for dust suppression, ore washing, flotation circuits, and process cooling. This water carries mineral fines, clay particles, scale-forming ions, and process chemical residues that must be managed to protect equipment and comply with environmental discharge limits.
K Factor inline pressure strainer systems and K-Optifil backwash filters protect mining process water circuits by removing mineral fines and abrasive particles before they reach pumps, heat exchangers, and process vessels. The self-cleaning operation eliminates the need for manual strainer cleaning in remote mine sites where maintenance labour is both expensive and logistically challenging.
Blast furnace and steel mill cooling water
Steel mills operating blast furnaces, electric arc furnaces, and continuous casting lines require large volumes of cooling water at consistent quality. Scale, iron oxide, and refractory fines in the cooling water cause tube fouling in heat exchangers, erosion of pump impellers, and nozzle plugging in spray cooling systems.
K Factor backwash pressure filters installed on blast furnace cooling water circuits remove scale and iron oxide continuously — protecting heat exchangers that would otherwise require frequent tube cleaning at costs of $10,000–$50,000 per event. The continuous operation requirement matches the blast furnace's own continuous operating cycle: both run 24/7 without planned shutdowns for maintenance.

Start Your 30-Day Free Trial
K Factor's 30-day free trial makes the K-Optifil or an inline pressure strainer system available in your facility at no cost and with no purchase obligation. We assess your flow rate, pressure, fluid, and contamination profile. We deliver and commission the system inline. You run it for 30 days and measure continuous flow performance, reject volume, and maintenance time eliminated. If the results don't justify the investment, return it. No invoice.
