These Ascorbic Acid Dechlorination Tablets are 100% organic, soluble, and non-toxic to fish and other aquatic life.
They provide a consistent reduction of chlorine residual without impacting dissolved oxygen levels.
The product is safer to handle than sulfur-based dechlorination chemicals.
Tablets can be repeatedly immersed and dried without loss of integrity or performance.
Enviro-C® offers a reliable and economical method for chlorine neutralization.
Performance is maintained at a uniform application rate regardless of flow, temperature, or humidity.
How Enviro-C® Dechlorination Tablets Work
Vitamin C Chemistry
Enviro-C® products utilize the unique chemistry of ascorbic acid (Vitamin C) to safely and effectively neutralize chlorine. This process provides a stable and consistent method for dechlorination that is also environmentally friendly.
Chlorine Neutralization Mechanism
The ascorbic acid acts as a strong reducing agent. It reacts quickly with chlorine and chloramines, converting them into non-harmful components. This reaction occurs without affecting the water's dissolved oxygen levels or releasing dangerous treatment chemicals into the environment.
Dosing Ratios
For proper dosing, one gram of ascorbic acid is required to neutralize 1 mg/L of chlorine per 100 gallons of water.
