Eliminate Rotten Egg Odor, Sulfur Smells, and Sediment Naturally with No Chemicals.  Fully Automatic.

Aerates and filters water using a particular type of catalytic activated carbon filter media

Combination of aeration and catalytic carbon instantly eliminates sulfur smells and odors

Optional Ozone generator kills sulfur and iron bacteria and sanitizes carbon media

Carbon filter media lasts for years.  There are no filter cartridges to change, and the filter media is easy to dump out and change years later.

High-tech Ceramic Disc Valve: The moving parts of the 7500 series control valve feature superhard ceramic and graphite meshing surfaces

Exacting tolerances, eliminating the need for O-rings or gaskets.

Easily programmable, multiple sequence set-up features, regeneration modes, and interlocking capabilities.

Backwashes automatically based on time (days of the week), typically two times a week for most homes.

Corrosion Proof: Resistant to sand, caustics, and acids.

Automatic recall after power outages and maximum day regeneration functions

Resists Abrasion: Patented ceramic discs are corrosion and abrasion-resistant for superior durability and longevity.

Exceptional High Flow Rate with noticeable noise reduction during regeneration

Advanced Features

Very long-lasting. A ceramic disc valve lasts years longer than standard piston-type control valves and backwashes over 150,000 cycles..

High activity granular activated carbon is manufactured by steam activation from select coconut shell charcoal and then specially treated for catalytic reactions

Carbon has maximum hardness and is well-suited for backwash applications.

Built-in battery backup: Holds time after being shut off for 3 days.  Holds program for 30 days or more.

Low maintenance, no routine maintenance required.

Chemical-free. No chemicals are required.

How does it work?

The system relies on the catalytic action of aeration and the catalytic carbon to instantly remove sulfur odors.  Unlike regular activated carbon, catalytic carbon is specially treated so a catalytic reaction takes place on the surface of the carbon.  This converts the odors into compounds that are adsorbed on to the carbon media.   It works best if oxygen is present so the combination of the aeration and the catalyltic carbon works great.

Why would I want or need the Ozone Option?

The Ozone Upgrade Option will automatically activate during the Air Draw cycle, drawing in ozone gas. Ozone is a powerful oxidizer and sanitizer and will sanitize the catalytic carbon filter media, allowing it to remove higher levels of sulfur odors and kill any sulfur or iron bacteria in the carbon if present.

How does the backwash work?

Every few days the 7500-Rev4 Sulfur Air control valve turns on and backwashes and cleans the filter media automatically.  Each time it backwashes it draws it expells the old air and draws in a fresh head of air.  During regular use the water flows from the top down through the KDF and carbon and then up the distributor tube out to the home.  When it backwashes the flow is reversed and water flows down the distributor tube and lifts the media up as it washes all the accumulated sediment and sulfide compounds out to drain.

How often does it need to backwash?

Depending on your water quality and usage this can be set by you to backwash from once a night up to every 7 nights.  Most homes have it set for every 3 to 4 days. 

How much water does it use during backwash?

This depends on the size but each time it backwashes and sucks in a new fresh head of air it runs for around 30 minutes and uses between 70 and 100 gallons.

Does the backwash water have to go to drain and my septic tank?

No not necessarily.  The backwash can be discharged into a pit or used in some applications for irrigation as the water has no added chemicals or salts. 

How often does the catalytic carbon media need to changed?

This varies based on water usage and the amount of sulfur odor present in the well water but generally the carbon lasts for 4 to 5 years.  It can easily be dumped out, and new carbon and poured in to the tank.  See more info and prices on the replacement carbon here.
