The ADLF automatic disc filter is composed of a group of plates with grooves on two sides. The intersection points formed by the edges of the grooves can intercept the solid matter in the water，then effectively remove organic and inorganic matter from the raw water. The intersection points also can highly catch soft impurities and fiber soft impurities. The filtration effect is greatly improved because of the functions of surface interception and deep condensation. At the same time, the disc filter has the characteristics of efficient backwash effect, automatic continuous operation, low water consumption, small covering and reliable operation, the backwash process of the filter system can alternately run in turn. It can automatically shift between working and backwash. In this way, it ensures continuous effluent, decreases system pressure loss. 

Doctor of philosophy, School of agriculture, Manica Institute of technology, Mozambique ，my customer , he is starting his own new farm now . At present, the farm has 180m ³/ H's pump is driving . Compare to sand filter high cost and difficult delivery , we suggest 100m³/h automatic back wash disc filter for drip irrigation system  , 50μm，inlet & outlet pipe size 4’’ , drain pipe size 3’’ , working pressure ≤1.0Mpa . Our customer is considering this solution , Next step our Aida will help him check cheap shipping way and cost .
