Closure, the advantages   The chlorine dioxide advantage Chlorine dioxide displays superior performance over other biocides by effective penetration of biofilms with an associated increased antimicrobial effect. Whilst chlorine dioxide needs to be generated on site, its neutral or acidic dilute aqueous solutions are stable if kept cool, well sealed and protected from sunlight. Chlorine dioxide is a good antimicrobial agent at very low concentrations (<1 ppm), has good virucidial and sporicidal properties and is also effective against biofilms. Chlorine dioxide is a more selective oxidant than other options, effectively cleaning protein molecule disulfide bonds. Chlorine dioxide doesn't hydrolyze into electrical current carrying ions that accelerate corrosion. • Effective against the broadest range of microorganisms • More effective than chlorine and other antimicrobials at inactivating viruses, bacteria, spores, yeast and mould and protozoa • Controls taste and odours caused by algae and decaying vegetation • Less affected by soil than other biocides • The bactericidal efficiency is relatively unaffected by pH values between 4 and 10 • Chlorine dioxide is superior to chlorine in the destruction of spores, bacterias, viruses and other pathogen organisms on an equal residual base • Required contact time is lower than alternative options • Chlorine dioxide has better biofilm penetration ability than other biocides • There are minimal corrosion concerns associated with CloSure generated chlorine dioxide • No THM formation • No chlorination of phenols • Efficient oxidation of iron and manganese • Less affected by organic load than chlorine • More advantages for direct contact food disinfection application - poultry, red meat, fish, vegetables • Approved for many applications - including with drinking water • Approved for no-rinse application - FDA • Only drinking water disinfectant able to remove Legionella biofilm without system shutdown A chlorine dioxide installation will revolutionise operational performance at your plant.     Closure: chlorine dioxide on demand While there are many methods for generating chlorine dioxide, most require either mixing very reactive materials together or waiting for a reaction process to complete. JohnsonDiversey's approach is to simply provide chlorine dioxide on demand. Closure dispenses safe and secure chlorine dioxide, ready-to-use at the point of application. Closure is an antimicrobial which is produced on site through a unique generating and dispensing mechanism, providing chlorine dioxide that is suitable for use in all food, beverage and dairy industries. Closure is a differentiated approach to the generation of chlorine dioxide solutions, making this technology inherently safer and more secure to distribute, dose and control for a wide range of applications, at varying volumes and concentrations. While based on acidchlorite reaction, the system does not require direct mixing of concentrated chemical precursors. • Safe, secure and simple • Easily integrated into current cleaning programmes • Wide range of applications • Risk free • Improved quality and productivity • Safety of generation and handling and versatility of use • Safety at higher level compared with other generation systems • More cost-effective than other water disinfection options • Technology is consistent and reliable • Consistent antimicrobial efficacy achievement • Overall rinse-water quality improvement   A complete service programme from JohnsonDiversey JohnsonDiversey offers a complete service package for the application and maintenance of a CloSure installation. Only JohnsonDiversey can offer the level of expertise and commitment to ensure the successful application of chlorine dioxide applications, taking into account all local regulations, application, safety and environmental issues. JohnsonDiversey offers a commitment to the safe, secure and simple application of chlorine dioxide onsite, providing: • Chlorine dioxide needs analysis • Full project management, from design to installation • Outsourced supply and maintenance • Benefit development • Complete financial package Customer requirements and expectations can reliably be met with a dedicated Closure engineering support for proper installation.   Where can I apply CloSure technology? Water Treatment Unlike chlorine or ozone, chlorine dioxide does not oxidize bromide, therefore water treatment with chlorine dioxide will not transform bromide ion into hypobromite and will not give rise to the formation of bromoform (CHBr3) or bromate. A common application of chlorine dioxide in drinking water has been for control of tastes and odours associated with algae and decaying vegetation. Chlorine dioxide is also effective in destroying taste and odour producing phenolic compounds. Chlorine dioxide can also be used to oxidize and remove both iron (II) and manganese (II). CIP Sanitation A 2-4 ppm disinfectant solution can be circulated safely through CIP circuits to give consistent microbial results with the advantage of removing processbiofilms too. Solution can also be reclaimed to save the residual chlorine dioxide and to prevent wasting active disinfectant solutions. Track Treatment Ability to use the same general rinse-water concentration (0.1-0.3 ppm), as is used throughout the plant, or to enhance bio control and hygiene on packing lines by using higher concentration. Track Treatment Vegetable Washing and Bottle Washing/ Rinsing Ability to use the same general rinse-water concentration (0.1-0.3 ppm), as is used throughout the plant for potable water rinsing, or higher concentrations where greater antimicrobial activity is required.     • MEDIUM TO LARGE SIZE BREWERIES & WINERIES • DAIRY PRODUCTION PLANTS • POULTRY PROCESSING PLANTS (WITH WATER CHILLERS) • LARGE SIZE BEVERAGE PLANTS (>5 FILLING LINES) • FISH & SEA FOOD PROCESSING FACILITIES (INCL.
