Ozone Treatment in Dairy Production

Ozone treatment in dairies

Dairies have since long used chemicals and hot water as a standard solution for disinfection. However, today there is a realistic option: ozone. With an efficient and reliable ozone system you can lower overall costs, simplify handling and reduce environmental impact.

Of all the unique advantages of ozone there is one that stands out. Ozone is produced on site from air – a free of charge natural raw material. No transport, no handling, no waste, no residues and extremely low environmental impact. Below we have gathered five processes in your dairy where our ozone treatment would give you great benefits. We have also made a table comparing ozone with chemicals and hot water.

Installation and validation are simple and do not affect your normal processes. Thanks to monitoring of the ozone concentration, a reliable and qualified sanitation can be achieved every time. Our high-performance system RENA Vivo - Dairy solutions has a footprint of only one quare meter. To summarize, implementing an ozone system in your dairy is easy.

Five ways to reduce costs and risks in your dairy with ozone

Efficient Clean-in-Place disinfection with added product quality

Dairy equipment ozone treatment

Utilize the unique properties of ozone as a disinfectant in CIP-processes. The strong oxidation potential along with its short half-life provides advantages that creates significant values for a dairy. Since no chemicals or heat are required the savings are easy to evaluate. Having no need for a last rinse increases up-time and reduces water usage. As a bonus a better product quality can be achieved.

Reduce handling and costs for cooling water control

Keep the cooling water in control with only a small amount of ozone in the water. Ozone can replace the standard biocides (and corrosion inhibitors) used at the dairies to keep the cooling water safe from microbial growth. Eliminate the cost for and handling of chemicals. Due to residual-free ozone technology, the need for bleed-off water treatment can also be significantly reduced.

Dairy bacteria control with ozone treatment

Increased potential for water recovery

Large amounts of water can be saved if evaporator condensate or membrane permeate is recovered. This water can be used for less critical applications such as rinsing or cleaning instead of fresh water. However, BOD levels often lead to microbial growth which effectively can be prevented by ozone. Naturally, ozone treatment involves no chemicals or residuals that can affect the hardware or environmental impact of the plant.

Quality assurance of process water

Improve the microbial standard in your dairy by using ozone treated water for critical applications such as final rinsing of equipment or flushing of product between batches. These actions can not only enable a better shelf-life but also enhance the run-time of the plant.

Prolonging brine life time

Retaining water, salt and proteins in the brine, without microbial growth, is often desired for efficient cheese production. With ozone, mould, spores and bacteria are reduced in an innovative and efficient 

manner. Ozone treatment has a number of benefits, for instance low maintenance and energy costs, compared to more traditional techniques.
