Control for Legionella in small buildings

A new chlorine dioxide generator with a capacity of up to 15 g/h has been introduced by ProMinent Fluid Controls as part of a new Bello Zon series for protection against Legionella bacteria

A new chlorine dioxide generator with a capacity of up to 15 g/h has been introduced by ProMinent Fluid Controls as part of a new Bello Zon series.

The new low capacity unit is ideally suited to use in small establishments such as retirement homes, where the inhabitants may be particularly susceptible to the Legionella bacteria.

Chlorine dioxide is a highly effective disinfectant and secondary dosing into both cold and hot water systems has been proven to be highly effective for the control of Legionella.

Chlorine dioxide dis-infection is also used to control Legionella in cooling towers, heat exchangers and other re-circulating pipes in buildings.

The new Bello Zon CDVb range extends from the 15 g/h generator to a top capacity unit capable of delivering up to 130 g/h.

Bello Zon CDVb generators use dilute solutions of hydrochloric acid and sodium chlorite to produce chlorine dioxide on demand, thus avoiding the problems of storing this highly reactive chemical.

The new series features new designs in the pre-mixer, reaction vessel and flow meter.

Chlorine dioxide is used for dis-infection in a host of other water treatment applications in a variety of industries including food, beverage and brewing.

It is particularly popular for its dis-infection efficiency, its residual disinfectant properties, its effect on bio-films and the fact that it does not impart any taste or odour to the water being treated.

Chlorine dioxide prevents the formation of chlorophenols, which can result in residual smells and flavours and will also remove any traces of them if they are present from other sources.

It does not react with amines to form chloramines and it does not form harmful trihalomethanes.

Chlorine dioxide is approved for use in potable water by the Secretary of State for the Environment at levels below 0.5 ppm.
