On-Site Hypochlorite Generation (OSG): Design Essentials & Benefits

This presentation introduces On-Site Hypochlorite Generation technology, a proven approach to producing sodium hypochlorite on-demand using just salt, water, and electricity. Attendees will learn why facilities worldwide are moving away from bulk chemical delivery and gaseous chlorine toward a safer, self-sufficient disinfection method. The session will cover the underlying process chemistry and how a generator converts salt, water, and electricity into a low-strength hypochlorite solution. As well as what makes this technology both safe and efficient compared to conventional disinfection alternatives.

The presentation then transitions into practical system design and sizing, covering the major components like electrolyzer cells, brine saturators, water softeners, storage tanks, and hydrogen mitigation. A dedicated safety and operations discussion will address hydrogen gas management and the built-in interlocks that keep generation rooms operating safely. 

Finally, the session will provide an economic perspective, including operating-and-maintenance life-cycle cost analysis and return-on-investment comparisons against bulk sodium hypochlorite and chlorine gas. Attendees will leave with a clear understanding of where on-site generation fits, how to evaluate it for their own applications, and best design practices for these systems.
