COMPLETE SYSTEM SCOPE
What an Industrial Ozone System Must Coordinate
Generator output is only one selection input. The surrounding gas, cooling, dosing, off-gas and control systems are project-specific.
Feed Gas and Ozone Generation
Generator selection depends on feed-gas source, required ozone concentration and output range.
Cooling and Power Control
Cooling conditions, utilities, power supply and control requirements must be defined with the generator.
Dosing and Off-Gas Treatment
Dosing, contact, distribution and off-gas treatment are selected for the treatment process and site layout.
Project Data for Selection
Flow, water or gas conditions, treatment objective and available utilities are needed before final sizing.
PROJECT REFERENCES
Documented Municipal Water Project References
The supplied catalogue identifies ozone-system references at water plants in Kunshan, Wujiang, Jinan and Shanghai.
Kunshan, Jiangsu, China
Kunshan Water Group 3rd Plant
Landmark project — first time a Chinese ozone supplier won a 200,000 t/d municipal water plant against incumbent international brands (OZONIA, WEDECO). Broke the situation where municipal water relied entirely on European ozone systems.
