Which applications require certification?

Applications related to municipal potable water and health care water treatment (hot and cold water systems in hospitals and aged care facilities) require NSF/ANSI 61 & 372 certification for chemical generators. Dioxide Pacific has obtained this certification to ensure the above-mentioned generators can be installed and operated in these applications.

What is NSF/ANSI 61 & 372?

The aim of NSF/ANSI 61 is to ensure that the generator does not add any undesired health related compounds to the water via the chemical it generates. NSF/ANSI 372 ensures that no lead is added to the generated ClO2 solution.

Note: NSF/ANSI 61 addresses health effects only and does not address the disinfection efficacy of the product

Why is it important?

Many States in the US require NSF/ANSI 61 & 372 certification for chlorine dioxide generators. Even if it is not peremptory, this certification is reciprocal in other countries as recognition of high chemical generation purity and therefore lowest risk for potable water and water for use as an ingredient in food products or for washing.

How do the generators work?

The Electricide® electrochemical chlorine dioxide generators produce 2,000 ppm chlorine dioxide solution which can be dosed and controlled to 3 dosing points. The generator PLC/HMI  automatically measures ClO2 residual and controls dosing of ClO2 solution to ensure accurate disinfection. Generators are equipped with secure remote access capability to view, operate and receive email alarm notification.

Chlorine Dioxide for CIP Sanitization

Dioxide Pacific has supplied Electricide electrochemical chlorine dioxide systems for CIP sanitization in food and beverage applications with great results. In many cases, chlorine dioxide has replaced peracetic acid mixes. Typically, chlorine dioxide is applied at 1-3 ppm and can be dosed into the sanitisation rinse (flow paced) or made up as a 1-3 ppm solution (PID controlled) and pumped to through the system. Peracetic acid is typically used at 50-100 ppm.

One such food ingredient producer has been using the Electricide CDE10 generator for 3 years. They were using peracetic acid dosed from a tote (IBC) using a metering pump and paying $80k per year for chemicals. During connection of a tote, an operator came into contact with the chemical. Peracetic acid has a pungent vinegar smell which aggravates eyes and burns the skin (peroxide ingredient). Management decided to look around for an alternative and decided chlorine dioxide should be trialed. After 3 months of successful operation, the system was purchased and installed. Current yearly running costs are around $10k and the capital purchase was paid back in less than 1 year. The customer is happy with the improved safety aspects of chlorine dioxide as Electricide-P1 (the chlorine dioxide precursor) has no vapor and is easy to connect to the Electricide generator. Chlorine dioxide solution at 2,000 ppm is pumped to a CIP make-up tank where 3 ppm solution is made-up and controlled. The 2,000 ppm solution is safe to pump through UPVC pipe and the 3 ppm solution has no corrosion issues in stainless steel tanks and pipework. One benefit of the Electricide electrochemically generated chlorine dioxide is the purity of the solution produced – no chloride and close to neutral pH. Other methods of chlorine dioxide generation produce chlorine dioxide with low pH and high chloride which increase the risk of stainless steel corrosion.

Chlorine dioxide can be used as a final rinse as it will not react to form any odor or taint producing by-products in food and beverage products. This aspect will save a lot of water and energy. Usually, peracetic acid requires a lot of water as a post-rinse to remove the chemical. Chlorine dioxide does not require this post-rinse.
