Material and methods
Demonstration activities will focus on three key sub-sectors: dairy products, brewery and winery.
The planned tasks are:
A. Preliminary actions. In order to get the necessary multidisciplinary background different
specific studies and reviews are produced: BAT documents, ozone technologies, CIP
techniques, environmental diagnosis of cleaning operations in collaborating food industries
B. Ozonecip prototype. A prototype will be created at AINIA’s facilities to simulate conventional
CIP processes and essay alternative processes based in ozone
C. Demonstration activities. Simulation of protocols comparing the environmental results
obtained when performed with and without ozone.
D. Evaluation. Water and chemicals consumption, hygienic results, wastewaters
E. Dissemination www.ozonecip.net
The tasks finished so far are task A and B: One of the key issues of the project is the pilot plant
where the demonstration trials will be performed. Experimental results are necessary so that ozone
CIP environmental benefits can be demonstrated. A number of variables will be controlled,
measured or analysed. Collected data will allow the definition of environmental indicators and
representative values and reach conclusions about the environmental benefits. The prototype allows
simulating industrial CIP processes carried out at food plants and assay processes based on ozone.
The prototype system consists of three subsystems: CIP pilot system, ozone generation and
injection system and the target equipment to be cleaned (Figure 2). Non-environmental factors that
can affect the applicability of the ozone CIP alternative will be considered.
