The OXAQUA system

HSD Water, offers OXAQUA, a reliable and sustainable inline water disinfection technology.

Based on the water electrolysis principle, OXAQUA can sanitize flow rates up to 10 m³/h (and bigger in custom applications) without any addition of chemicals nor precursors such as sodium chloride and create a safe residual of oxidizer up to the end-user’s point of use.

OXAQUA uses the chlorides naturally present in the water to be treated (concentration has to be above 20 ppm Cl-) to generate on site and on demand up to 2 ppm of free chlorine under the form of hypochlorous acid, a strong oxidizer known for the prevention of the proliferation of bacteria, viruses, algae and molds in drinking and hot water systems. It is also efficient against many pathogens, such as E. Coli or Legionella Pneumophila.

Key applications of the system are:

Primary drinking water disinfection (Private Wells, Municipal Supplies)
Chlorine boosting stations on drinking water networks
Top-up chlorination on private networks (hotels, resorts, hospitals)

In-line water disinfection

Although it is generating a sanitizer, OXAQUA does not require any handling of chemicals, ensuring a minimum manpower and an extremely low carbon footprint.

The core of OXAQUA, the electrolysis cell, has a lifetime of up to 8,000 hours of operation, and the power consumption of less than 500 Watts for 10 m3/h of treated water allows its installation not only on small to mid-size water supplies but also in remote locations such as islands, mountain sides or isolated communities.

OXAQUA is available in different versions depending on the flow rates to be treated (1 – 2 – 3 – 5 – 10 m³/h and bigger for custom applications) and can optionally be equipped with a communication modem and a chlorine sensor to adapt the production to the exact need of the water to be treated.

Implementing & operating OXAQUA

OXAQUA is a compact system, easy to install and to control, even on existing pipework for retrofitting or replacement of obsolete disinfection systems.

It is easily operated through an intuitive control panel and monitoring of the performance can be done through the built-in data-logger (optional).

Maintenance operations are limited and do not require specific skillset or personal protection equipment.

The equipment can be used indifferently for primary disinfection or for inline re-chlorination (boosting stations).
