WP3 Water efficient production lines including closed loop solutions

Promising scenarios for water savings and reuse obtained through new improved production equipment or innovation to conventional production lines through new closed water loops will be tested – in pilot scale or larger scale – by technology providers and end-users. With a view to strengthening the later commercialization of attractive solutions a strong focus will be put on solid documentation of technology performance and preparation of well-defined business cases. Further, sustainability assessments and eco-efficiency considerations for attractive technology solutions will be undertaken and eco-efficiency will be compared to benchmark production schemes.

Objectives for WP3

  • To develop, test and – where feasible – demonstrate new technology and solutions for increased water efficiency through introduction of new water saving production technology or new closed water loops within the four industrial sectors: dairy processing; brewery; marine ingredients; slaughterhouses and meat processing.

WP4 Cleaning technology and concepts – including CIP (Clean-in-place)

Cleaning processes often use large amounts of water. This WP investigates opportunities for reducing water usage during cleaning in a hygienic safe manner. Different scenarios will be investigated in pilot scale or even at larger scale for the different food sectors – an investigation done in close collaboration between technology providers, end-users and research partners. A benchmark case will be selected and form a point of reference for other technologies. The potential to apply process control and sensor technology to exploit actively on-line data streams will be evaluated with the aim of shortening and optimising cleaning procedures. The investigations will be supplemented with economic analysis as well as assessment of hygiene and food safety. Detailed documentation of all tests including microbiological and chemical parameters will create the data required for the preparation of a solid business case for the most promising technological solutions.

Objectives for WP4

  • To develop, test, and implement cleaning strategies for reduced water usage during the cleaning process within the four food sectors involved in the project using new and existing cleaning technologies, sensor technologies, and data treatment methods.

WP5 Wastewater treatment and reuse in utility functions or industrial symbiosis

Treatment of effluent or process water to achieve the quality needed for a specific reuse in utility functions like cooling water, boiler feed water, etc. will often be an attractive option since the reuse scheme is not subject to food safety regulations. Based on the water-fit-for-purpose concept a train of water treatment and separation technologies will often have to be applied in each case to achieve the desired water quality. Considering the diversity of the process water streams in the four involved food sectors these treatment solutions have to be custom made to some degree for the specific production process and the new and advanced technologies will be applied to achieve financially attractive and eco-efficient solutions. A focus in the technology development will be on cost-effective removal of carbon and nitrogen combined with membrane filtration and disinfection, and especially on the interaction between first stage biological treatment and second stage polishing. At the same time these solutions will most often prove to be very well suited for industrial symbiosis applications where treated effluent or process water is exported to nearby water consuming industry.

Objectives for WP 5

  • To develop, test and – where feasible – demonstrate, new technology and solutions for cost effective end of pipe process water treatment and reuse of treated water in utility functions of dairy processing, brewery, marine ingredients and slaughterhouses and meat processing or supply to other industries in a symbiosis partnership.
