Higiena procesu płukania
Głównymi zadaniami pojawiającymi się przy zachowaniu higieny procesu płukania są dezynfekcja butelek lub puszek oraz dalsza sterylizacja wody płuczącej. Klienci firmy ProMinent używają od lat rozwiązania opartego na dwutlenku chloru, jak i ozonie.
Disinfecting with Chlorine Dioxide
Chlorine dioxide is without doubt, among the best solutions for this application. Second to ozone, chlorine dioxide is the most effective and quickest way of killing bacteria. It can be easily and quickly rinsed through and is permitted for the treatment of drinking water. This means it can be used without any danger of interactions in the rinsing water.
For the after-rinse (last injection), sterile water of drinking quality is used with less than 0.2 ppm chlorine dioxide. The rinse water is captured in a nearby tank and concentrate is added for bottle disinfection (1st injection) at a concentration of approximately 1.5-2 ppm. Because the water is used several times over, there are significant savings to be realized.
This process is achieved using ProMinent technology for the production and distribution of chlorine dioxide with appropriate ProMinent controllers, probes and dosing pumps. The freshly produced chlorine dioxide is stored as a solution of around 1,000 ppm in a secure chemical tank with fill level monitoring and then dosed using Beta, Gamma or Sigma pumps. Pump control for drinking water treatment is proportional to volume while the pump for adding concentrate to the swimming pool is controlled using a D1C controller for chlorine dioxide.
Disinfecting with ozone
Ozone is one of the most important disinfectants. It has an exceptionally broad spectrum of treatment areas, such as bacteria, viruses, spores and parasites. Disinfecting bottles with water containing ozone in the rinser is a very effective pre-treatment process. Ozone kills more germs than any other disinfectant in a shorter time.
The picture shows a compact ozone plant OZVs for producing and dosing ozone for disinfecting injection water in the rinser as well as for PET bottles and glass bottles. The plant incorporates
- Ozone generator
- Measured value control
- Ozone monitoring
- Storage tank
The OZVa ozone plant can be used in all standard types of rinser and subsequent addition of parts to existing rinsers is possible at any time. The plant has a particularly compact design and is easy to install. Typical application concentrations are 0.5 – 1 ppm ozone. The volume of injection water to be treated is on average 1 - 3 m3/h. The purification rinsing water concentration levels can be increased and then used for pre-injecting.
