Drinking water utilities face a critical challenge: how to dose chlorine accurately into already treated water to ensure microbiological safety—without compromising water quality or violating chlorate limits. Chlorination is essential to prevent pathogens like Legionella, but improper dosing or storage can lead to the formation of disinfection by-products such as chlorate.
The conventional approach: chlorine gas cylinders and bulk hypochlorite
Traditionally, drinking water utilities used chlorine gas or bulk sodium hypochlorite for disinfection. While effective, both have serious drawbacks. Chlorine gas is highly toxic, requiring strict safety infrastructure, trained staff, and continuous monitoring. Bulk hypochlorite degrades quickly, especially under heat or UV, forming chlorate — a regulated by-product with health risks. Over time, its effectiveness drops while compliance pressure rises. These conventional methods compromise both safety and water quality, making them less viable under today’s regulations.
The VDH solution: fresh and pure chlorine, generated on-site
VDH Watertechnology offers a safer and more sustainable approach to drinking water disinfection by generating fresh and pure chlorine directly on-site. This method eliminates the need for bulk storage and transport of hypochlorite or chlorine gas, both of which are known to degrade over time and contribute to the formation of chlorate—a regulated disinfection by-product.
The heart of VDH’s solution lies in its advanced Chlorinsitu® electrolysis systems. These technologies use either membrane or open-cell electrolysis to produce sodium hypochlorite at the point of use, ensuring the chlorine is fresh, stable, and effective.
