Salt electrolysis

Salt electrolysis is an advanced on-site generation technology that produces sodium hypochlorite (NaOCl) or hypochlorous acid (HOCl) by electrochemically splitting a saturated brine solution (NaCl) in high-efficiency membrane cells.

This proven method—embodied in VDH’s CHLORINSITU® and DULCO®Lyse systems—yields an ultra-pure disinfectant with exceptionally low chloride and chlorate levels, ensuring maximum efficacy, safety and sustainability in water treatment.

Membrane technology

Membrane technology is the cornerstone of modern water disinfection. At VDH Watertechnology, we leverage high-performance membrane cells to generate pure sodium hypochlorite (NaOCl) or hypochlorous acid (HOCl) directly on-site.

By selectively separating ions, our membrane systems keep unwanted byproducts such as chlorates and chlorides to an absolute minimum—delivering a safer, more effective and environmentally sustainable disinfection solution.

Customization is our expertise.

very application—whether it’s process water in a dairy plant, wastewater reuse in the paper industry or hygienic rinse water in food production—comes with its own set of challenges. At VDH Watertechnology, we design truly bespoke water disinfection systems that align perfectly with your specific requirements.

From on-site chlorine generation via membrane electrolysis to tailor-made system layouts, we factor in flow rates, salt quality and spatial constraints right from the start. This precision engineering prevents chemical overdosing, eliminates degradation of reagents and minimizes environmental impact—delivering a reliable, future-proof installation that maximizes safety, efficiency and sustainability.Ask ChatGPT
