Transform water chemistry. Enhance every cup.
CARBONATE X-MG® is a specialty dealkalization and magnesium-enrichment media developed for coffee, tea, drinking water and food-and-beverage applications.
Developed by Watch Water® GmbH in Mannheim, CARBONATE X-MG® is designed to reduce carbonate alkalinity, convert carbonate species toward bicarbonate conditions and release magnesium into treated water. By adjusting alkalinity and mineral composition, the media helps protect coffee machines, vending equipment and household appliances from carbonate-scale accumulation while creating a water profile suitable for balanced beverage extraction. Selected configurations also incorporate HydroSorb® adsorber for additional contaminant reduction.
Dealkalized. Magnesium-enriched. Engineered for exceptional beverages.
The complete water recipe for coffee, tea and premium drinking water.
One specialty media.
Multiple beverage-water applications.
CARBONATE X-MG® is designed for systems where alkalinity, magnesium content, scale protection and beverage extraction must be managed together.
Coffee Machines and Espresso Systems
Helps manage carbonate alkalinity, protect equipment and create a suitable mineral profile for coffee extraction.
Tea and Hot-Beverage Systems
Supports balanced mineral content and reduced carbonate-scale formation in hot-water equipment.
Household Drinking-Water Filters
Suitable for cartridge and point-of-use systems designed to produce magnesium-enriched drinking water.
Vending Machines
Supports scale control and consistent water chemistry in commercial beverage-vending equipment.
Restaurants, Cafés and Hospitality
Provides application-specific water conditioning for cafés, restaurants, hotels and food-service operations.
Food and Beverage Production
Suitable for beverage processing and specialty-water systems requiring controlled alkalinity and mineral composition.
Four water-quality functions engineered into one treatment concept
Carbonate-Alkalinity Control
CARBONATE X-MG® reduces carbonate alkalinity and shifts carbonate chemistry toward bicarbonate conditions, helping manage scale potential and beverage-water buffering.
Mineral Adjustment for Beverage Extraction
The magnesium-containing component releases magnesium ions into the treated water, helping create a mineral profile suitable for coffee, tea and drinking-water applications.
Protection for Coffee and Vending Equipment
Reduced carbonate alkalinity helps lower the potential for carbonate-scale accumulation in coffee machines, heating elements, vending systems and connected appliances.
Optional Reduction of Selected Contaminants
When HydroSorb® is included in the system, its adsorptive component is intended to reduce chloramines, organics and selected micropollutants. Performance depends on the HydroSorb® quantity, influent conditions and contact time.
Science &
Technology
CARBONATE X-MG® combines dealkalization, hydrogen-ion activity, magnesium release and optional adsorption to adjust water chemistry for beverage preparation and equipment protection.
- Carbonate-to-Bicarbonate Conversion – Carbonate ions react with hydrogen ions to form bicarbonate.
- Dealkalization and pH Adjustment – The brochure describes an increase in hydrogen-ion content during treatment, producing a lower service pH and reduced carbonate alkalinity.
- Magnesium-Ion Release – Magnesium-loaded media releases magnesium ions into treated water. Magnesium can influence coffee extraction and the sensory profile of prepared beverages.
- Optional HydroSorb® Adsorption – HydroSorb® may be incorporated to provide additional adsorption of chloramines, organics and selected emerging contaminants.
