About the Physical Methods Applied by Underground Water Treatment in Food Industry

The modern food industry requires high quality processing water at greater flow rate. The actual paper presents an original computer controlled pilot equipment in multiple stages: fresh air treatment in the underground pipe, treatment in pulsating electric filed, water softening in electromagnetic field and the disinfection in ultraviolet (UV) ray. The high-level water purification is ensured in two additional stages: biologic nitrification and filtration with active coal. The main advantage of the proposed method consists of the avoidance of the usual chemicals, expensive and problematic by further filtration. The whole process, with interconnected variables, is computer controlled, achieving an optimum mode of operation
