Sulfur Block System
Get Clean & Refreshing Water
Get the clean, refreshing water you deserve with the Watershield™ Sulfur Block System. Innovative in design, the Watershield™ Sulfur Block System provides a simple, effective solution requiring no chemicals or salt for regeneration. The blend of media used effectively removes sulfur, hydrogen sulfide gas, heavy metals, bacterial growth, and other taste-affecting contaminants. The Watershield™ Sulfur Block System is a single tank solution, taking up much less space than the unsightly contact tank and aerator tank solutions. Also, being a closed system, it does not have the unsanitary and algae growth problems that come with open-air aerators. For a total soft conditioned water solution, team up the Watershield™ Sulfur Block System and a Watershield™ Gold water conditioning system and get great, soft, and odor-free water today.
This advanced system takes efficiency and convenience to the next level. It features an intuitive, backlit screen and an energy-saving display that only regenerates when needed to maximize efficiency.
While our standard Sulfur Block System easily handles everyday well water, extreme “rotten egg” odors and iron bacteria require a more aggressive approach. By integrating a Proportional Hydrogen Peroxide Injection System, we neutralize the toughest water issues before they even reach your filter.

Key Features & Capabilities
On-Demand Regeneration: Minimizes waste by only cycling when actual water usage requires it.
Color-Coded Interface: Quick-glance visual displays make system status easy to understand.
Diagnostic & Maintenance Alerts: Built-in error notifications and automated service reminders keep your system running smoothly.
Lithium Battery Backup: Extended power protection ensures your settings are saved during outages.
Dual Relay Outputs: Built-in connectivity to easily control external chemical pumps, auxiliary alarms, or peripheral equipment.
Flexible Configurations: Available in both space-saving cabinet designs and high-capacity twin-tank models.
- Instant Odor & Bacteria Destruction: It oxidizes hydrogen sulfide (“rotten egg” smell) on contact and cleanly eliminates slimy iron bacteria before it can stain your fixtures or clog your filtration system.
- Eco-Friendly with No Chemical Aftertaste: Unlike traditional chlorine systems, hydrogen peroxide breaks down completely into pure water and oxygen ($H_2O$ and $O_2$), leaving behind zero chemical residues, odors, or chemical tastes.
