Chlorine Dioxide
Disinfection
Chlorine dioxide is a specialist oxidizing biocides that offers a number of advantages for water disinfection compared with other disinfectants such as chlorine:
- 7 times stronger oxidant than chlorine
- Selective oxidant and so does not react with many process contaminants, organics
- Extremely effective biofilm dispersant
- No dangerous by products e.g. THM’s
- Low impact on corrosion
Wide range of applications:
- Disinfection of drinking water
- Disinfection of wastewater
- Phenol destruction in wastewater systems
- Effective control of legionella in cold and hot water systems
- Water disinfection in air conditioning system cooling towers
- Disinfection of product and service water
- Bottle cleaning, rinser and pasteurizer
- Cold sterile bottling
- Disinfectant in CIP systems
- Condenser water treatment (condensate) in the milk industry
- Disinfection of wash water for fruit, vegetables, seafood, fish, poultry
- Cooling water treatment
- Seawater cooling control of mussels and planktonic organisms
- Combating legionella in cooling circuits
- Disinfection of process water
- Removal of odorous substances in air scrubbers
Specialist Generation Techniques
Chlorine dioxide is an extremely reactive gas, which because of its instability – cannot be stored, and must only be produced in the required quantities in special generators on the site where it is to be used.
The ZI-CHEM® technology is based on a new generation of chlorine dioxide generation systems that utilize both two and three chemical pre-cursor processes.
This compact unit produces clean ClO2 on demand by mixing controlled amounts of 25% sodium chlorite with either gaseous chlorine, or sodium hypochlorite and hydrochloric acid.
Chlorine dioxide is generated in the revolutionary new dual ZI-OX reaction columns. The chlorine reacts in milliseconds with the chlorite stream to produce chlorine dioxide which is immediately diluted into the motive water stream.
ZI-CHEM ZI-OX Chlorine Dioxide Generators- Key Features-
- Multi-level safety features
- High efficiency reaction up to 95%
- Simple rapid installation
- Simple to operate & maintain
- Small footprint for maximum space utilization
- Option for auto control of feed rate proportionate to demand using on-line instrumentation that measures residual Low cost Proven technology in many applications
