SYSTEMS

DESIGN

COMBINIX’S PACKED BED CONFIGURATION

The four media’s will settle in the pressure vessel according to their respective weights and densities. The heavier media will naturally settle at the bottom, while the lighter ones will be positioned higher up. Here’s the expected order from top to bottom:

1) AQUARedox - 20%

Effective for organic and inorganic compounds including  emerging contaminents.

2) Catalytic Carbon - 20%

Coated with Zero Valent Iron (ZVI) for high-efficiency removal of organic compounds, heavy metals, chlorine, and chloramines.

3) Cationix - 40%

Efficient softening media, regenerates with only 80 grams of salt, designed for low-maintenance operation.

4) Katalox Light - 20%

Superior in removing iron, manganese, and hydrogen sulfide, ideal for high catalytic filtration system.

COMBI-MIX

SINGLE-STEP REGENERATION

All four media regenerate together using only 80 grams of sodium chloride per liter of Cationix Media. This process lowers environmental impact and operational costs, making COMBI-MIX™ more efficient than conventional water softeners. The Water Metered Control Valve automates regeneration, ensuring consistent system performance without constant supervision.

FREQUENTLY ASKED​

QUESTIONS

What is COMBI-MIX™?

COMBI-MIX™ is an advanced, all-in-one water treatment media developed by Watch Water® in Germany. It integrates four powerful filtration technologies—AquaRedox, Catalytic Carbon, Cationix, and Katalox Light—into a single system for superior purification.

What contaminants does COMBI-MIX™ remove?

It effectively removes hardness (CaCO₃), iron, manganese, hydrogen sulfide, chlorine, chloramines, heavy metals (lead, chromium), radioactive contaminants, PFAS, trihalomethanes (THMs), microplastics, ammonia, and microbial contaminants.

Is COMBI-MIX™ suitable for both residential and commercial use?

Yes. It is designed for both residential drinking water and commercial water treatment systems.

How does the regeneration process work?

COMBI-MIX™ uses a single-step regeneration process with just 80 grams of salt per liter of Cationix media. All four media regenerate simultaneously, reducing maintenance and operational costs.

How much water waste does COMBI-MIX™ produce compared to traditional systems?

Its proprietary design drastically reduces wastewater compared to conventional filtration systems.

What makes AquaRedox unique in COMBI-MIX™?

AquaRedox enables powerful redox reactions that both oxidize and disinfect water while removing a wide range of organic and inorganic contaminants. Its sustainable self-regenerating redox cycle ensures consistent performance and long-term effectiveness.

How does Cationix improve water quality?

Cationix removes calcium and magnesium by ion exchange (replacing them with sodium or potassium), preventing scaling and improving water quality.

Can COMBI-MIX™ remove chlorine and chloramines?

Yes. Its Catalytic Carbon with Zero Valent Iron (ZVI) efficiently removes chlorine and chloramines, unlike standard activated carbon.

What is the lifespan of COMBI-MIX™ media?

Each media component has an expected service life of 5 years under recommended operating conditions.

Is COMBI-MIX™ environmentally friendly?

Yes. COMBI-MIX™ minimizes salt and wastewater consumption, making it more sustainable than traditional systems.

Does COMBI-MIX™ require frequent backwashing?

No. COMBI-MIX™ uses a proprietary blend of media with optimized granule sizes, which minimizes channeling and makes backwashing more efficient. This reduces water use and lowers maintenance compared to conventional systems.

What are the operating conditions for COMBI-MIX™?

 It works in a temperature range of 5–80°C. The pH range varies by media, from 5.0 to 10.5 overall, and it supports both upflow and downflow configurations.

How is COMBI-MIX™ packaged?

 It comes in 25 L bags (22 kg each). The standard pallet quantity is 40 bags with a gross pallet weight of 905 kg.

How do I install COMBI-MIX™ in my system?

 Installation should follow Watch Water®’s system configuration guidelines, ensuring the proper order of media layering for optimal performance.

How does COMBI-MIX™ compare to traditional water softeners?

Unlike conventional systems, COMBI-MIX™ combines softening, filtration, oxidation, and adsorption in a single step, reducing salt usage, water waste, and maintenance needs.
