Water Treatment Tablets

Understanding Water Treatment Tablets

Water treatment tablets are commonly associated with disinfection, but they also serve a critical role as dechlorinating agents—neutralizing residual chlorine and chloramine in treated water. This function is especially important in applications like municipal hydrant flushing, wastewater discharge, and environmental protection, where chlorinated water could harm aquatic ecosystems. Dechlorination tablets, such as those made with sodium sulfite, sodium ascorbate, or ascorbic acid, effectively break down chlorine compounds, making the water safer for release or further use. These tablets are compact, easy to apply, and dissolve quickly or slowly depending on the formulation, providing controlled chlorine neutralization without introducing harmful byproducts. Ideal for public works, construction, and emergency response teams, dechlorinating tablets offer a simple, NSF-approved method for maintaining compliance with environmental discharge regulations and safeguarding natural water bodies.

EnviroREDI Sodium Sulfite Dechlorination Tablets

EnviroREDI Sodium Sulfite Dechlorination Tablets offer a powerful, eco-friendly solution for neutralizing chlorine in water systems, especially during hydrant flushing, pool drainage, and wastewater discharge. Each tablet contains 92% sodium sulfite and 8% proprietary dissolve-rate control additives, ensuring fast, consistent dechlorination down to non-detectable chlorine levels. One tablet can treat up to 19,000 gallons of water with 1 ppm chlorine, helping protect aquatic life and meet environmental compliance.

Enviro-C® Dechlorination Tablets

Enviro-C® Dechlorination Tablets are NSF-certified water treatment tablets made with 75% ascorbic acid, designed to safely and effectively neutralize chlorine and chloramines in municipal, wastewater, and process water applications. These eco-friendly, non-toxic tablets are 100% organic, fully soluble, and safe for aquatic life, making them ideal for environmentally conscious dechlorination.

Bio-Sanitizer® Slow Dissolve Disinfecting Tablets

Bio-Sanitizer® Slow Dissolve Disinfecting Tablets are EPA-registered, high-efficiency water purification tablets made with calcium hypochlorite, offering a minimum of 70% available chlorine for powerful, consistent disinfection. Designed for use in commercial, industrial, and municipal water and wastewater treatment systems, these slow-dissolving tablets ensure uniform chlorination and adapt to flow rates for optimal performance. Their bevelled-edge design reduces wicking, while the environmentally responsible formula helps prevent bacterial regrowth.

FAQs

1. Can I use regular drinking water treatment tablets to remove chlorine?

No, tablets designed for disinfection (e.g., iodine or chlorine dioxide tablets) are not suitable for removing chlorine or chloramine. Instead, use dechlorination tablets specifically formulated for neutralization, such as those made with ascorbic acid or sodium sulfite.

2. What is the difference between dechlorination tablets made from ascorbic acid and sodium sulfite?

Ascorbic acid tablets are more environmentally friendly and safe for plants and aquatic life, while sodium sulfite tablets are highly effective and commonly used in municipal and industrial applications. Both work well, but the choice depends on environmental sensitivity and intended use.

3. How fast do dechlorination tablets work to remove chlorine or chloramine?

Most dechlorination tablets act quickly—often within a few minutes—depending on water volume, temperature, and flow conditions. Proper mixing is essential to ensure even distribution and complete neutralization.

4. Do these tablets also remove other contaminants besides chlorine and chloramine?

No, chlorine-neutralizing tablets are designed only to target disinfectants like chlorine and chloramine. They do not remove bacteria, heavy metals, sediments, or organic pollutants and should be used alongside other treatment methods when broader purification is needed.

5. How should dechlorination tablets be stored to maintain their effectiveness?

Store them in a cool, dry place in a sealed container to prevent moisture exposure and premature breakdown. When properly stored, most tablets maintain potency for 1–2 years, but always check the manufacturer's expiration guidelines.
