Water disinfection is only as reliable as the supply behind it.
Recent events in South Africa have highlighted the risks that can arise when municipal water treatment depends heavily on delivered chlorine or hypochlorite.
Supply interruptions can result from price escalations, contract disputes, late deliveries, transport disruptions and stock-outs. Bulk hypochlorite can also lose strength while in storage.
On-site HOCl generation offers a different approach.
Hypochlorous acid can be generated at the treatment plant using salt, water and electricity, reducing dependence on a single chemical supplier and avoiding the need for bulk hazardous chemical deliveries. Systems can also provide continuous controlled dosing, with online monitoring and alarms to flag dosing failures.
Independent laboratory testing has demonstrated over 99.4% bacteria reduction at 8 ppm HOCl, outperforming conventional hypochlorite at ten times the dose.
For municipalities, water utilities and treatment facilities, supply security isn't simply a logistics issue — it is part of protecting reliable water disinfection.
Safe water shouldn't depend on a supplier's price list.
