In the framework of liquid treatment processes, with the aim of ensuring public health security for drinking water or to prevent economic damage, when safeguarding important production processes, major investments have been devoted to research, study and design of innovative products able to respond to market demands, that offer nowadays several solutions. The present work focuses, specifically, on the filtration of drinking water with filter cartridge systems, with the aim to investigate the effect of their introduction into a hydraulic system in terms of head losses. The problem is particularly important when the cartridge is installed in hydraulic plants characterized by low pressures, in which its insertion can make the pressure levels fall below the minimum limit recommended to ensure the smooth operation of domestic devices. Specifically, the behavior of seven different commercial filter cartridges was analyzed through an experimental analysis conducted in a pilot circuit at the Laboratory of Environmental and Maritime Hydraulics (LIDAM), University of Salerno. Experiments have been performed here in different operating conditions, detecting pressure data in different points through piezometric gauges. The analysis provided some information useful in the choice of the proper cartridge in low-pressure distribution systems.

The problem is particularly important when the cartridge is installed in hydraulic plants characterized by low pressures, in which its insertion can make the pressure levels fall below the minimum limit recommended to ensure the smooth operation of domestic devices.
