Drinking Water

Mains, reservoir and well-fed systems share the same problem: water that is clean at the source picks up microbiological load along the line before it reaches the user. Standing time in reservoirs, dead legs and biofilm create a risk layer invisible at the measurement point.

Disinfection layer

The Aquamirus E.C.A. system applies demand-based hypochlorous acid dosing at reservoir inlets and outlets or on the network pumping line. Free-chlorine measurement on the line continuously corrects the dose; over-chlorination and the associated taste-and-odour complaints and trihalomethane formation are minimised. The penetrating power of hypochlorous acid on biofilm also lowers the network’s long-term microbiological load.

The second output: caustic

The cell in the Aquamirus E.C.A. system produces sodium hydroxide (caustic) at the cathode alongside the hypochlorous acid used for disinfection. Caustic is a familiar chemical in water facilities: where the process and the applicable regulations allow, the catholyte can be used for pH correction or for alkaline cleaning of tanks and equipment, rather than being bought in separately. How it is used is set during the site assessment.

Typical installations

Municipal drinking-water reservoirs, drinking-water bottling plants, hotel and residential water tanks, and campuses and production sites with their own supply. The system is sized to the facility, from a single reservoir to network scale; Skytech Water designs, installs, commissions and services it on site.
