For many decades chlorine gas has been the predominant
chemical for the disinfection of water.
The most economic
disinfectant is available as gaseous or liquid chlorine
supplied in cylinders or ton containers. Using a remote
vacuum operated gas feeder a chlorine solution is prepared
on site from chlorine gas and water. This solution is
used as disinfectant.
Wallace & Tiernan chlorinators operate to the all-vacuum
principle, this means there is vacuum from the cylinder
up to the injector.
The full vacuum gas feeder V10k and the other models can also be used
for metering carbon dioxide (CO2)
for lowering the pH and for hardwater conditions of potable water. The
full vacuum gas feeders are also suitable for sulphur dioxide (SO2) for dechlorination applications and for ammonia (NH3).
The gas feed system V10k is designed for capacities up to 15 kg/h of
chlorine gas and the gas feed system S10k comprising of a vacuum
regulator, a gas control unit and an injector for capacities up to 10
kg/h.
