Automatic Backwash Regeneration
Granular Activated Carbon (GAC) Filtration
· Water flows through bed of AQUAFINE® granular activated carbon
· Carbon has millions of microscopic pores that trap contaminants
· Adsorption process physically captures chlorine molecules and organic compounds
· Each carbon granule acts like a tiny sponge with enormous surface area
· One pound of activated carbon has surface area equivalent to 100 acres
Chlorine Removal Process
· Removes up to 97% of chlorine from over 1,100,000 gallons of water
· Chemical reaction converts chlorine to harmless chloride ions
· Eliminates chlorine taste and odor from drinking, cooking, and bathing water
· Protects skin and hair from drying effects of chlorine
· Prevents chlorine from damaging plumbing fixtures and appliances
Chloramine Reduction (DFTOC/DFTOCK Models)
· Special catalytic granular activated carbon breaks down chloramines
· Chloramines are more stable than chlorine and harder to remove
· Catalytic carbon accelerates the breakdown process
· Removes both chlorine and ammonia components of chloramines
· Essential for areas where water utilities use chloramine disinfection
Chemical Contaminant Removal
· Removes heavy metals including lead and mercury through adsorption
· Captures pesticides and herbicides from agricultural runoff
· Eliminates volatile organic compounds (VOCs) from industrial sources
· Removes trihalomethanes (THMs) formed during water treatment
· Filters out toxic organics, phenols, and tannins that affect taste and odor
Optional KDF Media Protection (DFTOK/DFTOCK Models)
· Kinetic Degradation Fluxion (KDF) media controls bacterial growth
· Copper-zinc alloy creates electrochemical reaction
· Prevents rotten egg odor caused by sulfate-reducing bacteria
· Particularly effective in warm water climates
· Extends carbon filter life by preventing bacterial fouling
· Available only in USA markets for specific water conditions
Automatic Backwash Regeneration
· Periodic backwash removes trapped particles and extends filter life
· Reverses water flow to flush accumulated contaminants
· Prevents channeling and maintains even water distribution
· Automatic timing ensures optimal performance without user intervention
· Extends carbon media life and maintains consistent filtration

Maintenance
When initially starting the water softener, add 5 to 6 bags of salt tablets. The average salt consumption is 1 to 2 bags per month. The active elements in the tank typically have a lifespan of 4 to 5 years and need to be replaced after that. Annual maintenance of the salt tank is highly recommended to remove any salt deposits accumulated throughout the year and keep the warranty valid.
