Ozone provides a safe, highly effective and energy efficient method of protecting pharmaceutical process water systems against microbiological activity in the water and biofilm contamination in the water system.
Ozone treatment ensures that the microbiological quality of the water and system hygiene are maintained within the most stringent water quality standards without the need for heat sterilisation or the use of chemical disinfectants.
The system can be routinely CIP cleaned and sterilised without draining down and with minimal disruption to production. With no chemicals being used, risk of product contamination is minimised. The process is both energy and time efficient, because there is no requirement to drain or flush the system during or on completion of the process. There is no wastage or loss of costly purified water.
Typical process water systems in the pharmaceuticals and cosmetics industries incorporate a water storage tank with recirculating ring main to distribute water to the process machines and applications.
Such systems, whether using purified or untreated water, are subject to biological activity with biofilm development on pipe walls and in the storage tank. Whilst UV units can control the bacteria levels in the water, bacteria such as Pseudomonas species will continue to develop, producing biofilm throughout the system and compromising the water quality. Control of such biofilm can only be achieved by circulating a disinfectant or biocide throughout the system. Ozone provides a safe and effective cleaning and biocidal treatment, replacing heat sterilisation and chemical processes previously used.
In normal operating mode, ozone injection into the recirculating loop return prior to the storage tank provides continuous disinfection of the tank and stored water. An ozone destruct UV on the output flow from the tank prior to the first point of use ensures that the residual ozone is destroyed providing high quality sterile water.
During periods when there is no production demand, switching off the UV lamp allows ozonated water to circulate freely throughout the system destroying any biofilm and disinfecting the complete system.
To resume production, the UV unit is switched back on, immediately destroying the ozone disinfectant in the recirculating water. This allows production to commence directly without the need for the system to be drained or flushed.
The level of ozone present in water can be readily and accurately monitored ensuring effective control of water quality.
In addition, Waterwise ozone systems, built to the high standards required for pharmaceutical processes, incorporate fault sensors to give immediate indication of fault or malfunction.
