Development of intelligent chlorination system for improving water safety and decreasing operation cost

To develop a smart electrochlorination system by optimizing the required chlorine dosages. The decreased and optimized chlorine dosage system will improve the organoleptic properties of the drinking water while maintaining the low risk water quality.

The proposed electrochlorination system is able to adopt to the diurnal and seasonal changes of water flows and water quality distributed in the water network. Seasonal and long-term changes in raw water quality e.g. (Danube bank filtration systems) are also effecting the water quality and organoleptic properties of the water served. All of these factors are required to take into account when chlorine dosages are determined. The intelligent chlroination system is based on the detailed hydraulic model of the distribution system with an integrated water quality modul. Compared with the traditional chlorination method the development of the intelligent electrochlorination system envisages the following main advantages: 1. The savings on chlorination costs by dosing only the required amount of disinfectant at the points where needed. 2. Stable free chlorine concentrations within the whole system due to strictly regulated chlorine production (regulated by water flow and quality) 3. Increased water safety and security (stable operation under emergencies, such as sabotage, or natural catastrophies). 4. Improved labor and health safety (no need to store and manage large volumes of chlorine gas) 5. Decrease of corrosion problems in pipelines. 6. Adoptability to water quality changes (plus diurnal, seasonal changes of raw water quality). The establishment of the new adaptive and intelligent chlorination system requires a series of investigations related to the oepration of the present water production techhnology and distribution network - water transport to consumers. The required studies and experiments are the followings: • The adoptation of the hydraulic model system of the distribution network for the determination of the exact residence times of the water at different points of the network (water ages). • Determination and prediction of the residual free chlorine concentrations on the operating distribution network. • Laboratory and pilot scale experiments for the determination of the boundary conditions of the operation of the electrochlorination units. The consortium members are representing one major potential user (Budapest Waterworks) of the disinfection technology to be developed by the SMARTCHLOR EUREKA project. The further R&D members of the consortium (Eotvos Jozsef College in Baja and Israeli SMEs - Mekorot and CQM) have different competence fields that will complement each other – piloting and technological expertise in Baja and technical design capacities in Israel. The lead partner (Inno-Water Inc.) has been in business relations with both of the Hungarian partners (Budapest Waterworks and Eotvos Jozsef College) and excellent professional records in developing water treatment technologies. These skills and capabilities make the consortium ideal for achieving the project objectives.
