Water disinfectant generator manufacturing. Technician building a generator used to dose a water supply with chlorine dioxide for disinfection purposes. The generators supply chlorine dioxide (ClO2) by the use of precursor chemicals. The ClO2 has the effect of disinfecting the water and making it safe to drink or use in a range of applications. This is the Alpha generator from Scotmas, used to deliver ClO2 continuously to water storage tanks. This manufacturing is taking place at the Scotmas company in Scotland. Photographed in 2016.
