As a rule, companies in the food-processing sector have to deal with large streams of waste water. Laws and regulations, as well as economical and sustainability motives are increasingly leading to the controlled purification of these waste-water streams. Industrial automation will ensure the controlled and documented closed process, whereby water can be used over and over again. We can realise this for companies in the food-processing industry as well as the maritime and offshore sectors. One of the challenges professionals like Van den Pol Industrial Automation are faced with is to limit energy consumption during these processes. Optimisation by means of automation will lead to a higher availability, reduced costs, and a better compliance.
