Water supply in small communities - Lenntech

Head loss in CMF is small, usually a few centimetres, with a maximum value around 0.30 m. Since the CMF units in small water supplies systems deal with low flow and low pressure values, some simplified valves, gates, and weirs can be used together with more commercial hydraulic devices.
