Water used for drinking and food production purposes is often microbiologically unsafe. There is a continuous risk of infectious disease outbreaks. Contemporary investigations show that safe food and drinking-water production is going to be a big global problem in the coming period. Gaseous chlorine is used for water disinfection in many countries today. Due to potential hazards and incidents the transportation and storage of gaseous chlorine are prohibited in EU since chlorine is a poisonous gas. Incidents can particularly involve storage tanks from which chlorine is dosed into water supplies. The objective of this paper is to develop a device for the generation of active chlorine as a disinfectant using harmless raw materials and an environmentally friendly technology that will not cause and adverse health effects in workers involved in the production. The device uses a dilute sodium chlorine solution (salty water) as a raw material and electrical energy to generate a dilute disinfectant (hypochlorite) solution. Hazardous chlorine tank are replaced with harmless table salt depots through the use of these devices. The devices can have different capacities and can be used for large municipal and small rural water supplies, rural wells for swimming pool water disinfection etc. They can also be used for wastewater treatment, food industry facility and equipment disinfection, textile bleaching, in the leather and pharmaceutical industries. In situ generated active chlorine, the solution of which is neutral, can be widely used in primary agricultural production (for disinfection of seed and livestock facilities). Optimum cell construction and optimum technological parameter values of the production processes have been defined. This comprehensive research has resulted in the construction of different types of automated remotely-controlled devices for active chlorine generation.
