1. INTRODUCTION General Description The MG110 is a sophisticated yet easy to operate automatic filter with a self cleaning mechanism driven by a hydraulic turbine It is designed to work with various types of screens in filtration degrees from 800 to 50 micron and is available in 10 inlet outlet diameter The MG110 filter is configured to meet your specific needs according to flow rates and water quality The filter can be installed as a stand alone unit for low flow rates or assembled in a group on a manifold when high flow rates and or a large screen area are required The filters are delivered fully assembled requiring simple connections to the inlet and outlet and to the drain Basic Filter Operation Waiter enters the filter from the inlet pipe and passes through a coarse screen which protects the automatic cleaning mechanism from any large particles or debris The coarse screen is not cleaned automatically and should not accumulate large quantities of solids The water then flows through a fine screen which filters out the smaller particles Water that has passed through the fine screen is clean and passes into the outlet pipe Particles of dirt accumulate on the fine screen and form a filtration cake which starts to restrict water flow As the restriction or clogging increases the pressure in the outlet pipe becomes lower than in the inlet pipe When the pressure differential reaches a pre set value a self clea2.
