Abstract
Usually, drinking water quality is required for water to be used in food industry. However, the drinking water is very often transformed right after the entrance in the food manufacturing factory by e.g. softening, cooling, heating, filtering, or addition of chemicals.
At this background it seems inappropriate to use drinking water quality as a standard for an appropriate water quality when upcycling water for reuse. An alternative approach is the Water-Fit-For-Purpose concept, based on identifying the needed water quality for a given purpose, and then treat the water to reach this quality.
To achieve this, treatment technologies have to be considered, as well as food safety, eco-efficiency, resource and economic issues. It is also crucial to consider all the essential parameters, and being aware of the weaknesses of a given technology since although e.g. membranes may be considered as efficient barriers, some small molecules such as organic micro pollutants, ammonia or trace metals may pass the membrane.
The Water-Fit-For-Purpose concept and its implementation is the foundation for the Danish DRIP partnership between food manufactories, technology providers, knowledge institutions and authorities – and this partnership has demonstrated that water efficiency can be improved by 20-30% in food and beverage industry
