Reducing energy requirements for sand filtration in microirrigation: Improving the underdrain and packing

Energy consumption in pressurised irrigation systems has become a major issue, even when microirrigation is used. Although the emitters used in microirrigation operate at low pressures, their filters require higher pressures and there is therefore no reduction in energy consumption. Part of the pres...
