Operation The water to be filtered enters into the filter and flows through the slotted tube elements from inside to outside. Impurities or sediments particles are retained on the smooth inner side of the filter elements. The particular design and shape of filter element guarantee an even flow resulting in a low pressure drop and equal loading of the filter area. As the loading of the filter area increases steadily during the filtration process, the differential pressure between the contaminated and the clean sides of the filter element also increases. When the differential pressure reaches its pre-set values, the back-flushing process starts automatically. During back-flushing a geared motor rotates the flushing arm under each filter element in succession and the back-flushing valve opens briefly. Due to a pressure differential between the filtrate side (clean water) and to open back-flushing line, a small volume of the filtrate is flushed back through the filter elements. The impurities or sediments which may collected on side of the filter elements is loosened and flushed out of the filter via the flushing arm. When all elements in the filter have been cleaned, the back-flushing cycle is complete. When one filter element is under back-flushing other elements continue the filtration and therefore filtration process do not stop and it is continuous.

ApplicationsPower station: Treatment of industrial water for cooling generators and filtration of cooling water, as side stream filterProcess industry: By filtration of cooling water, protect the surface of heat exchangers and other equipment from coating. Improve the heat exchanger capacity. Reduce the time and cost.Steel industry: Protection of nozzles and pumps during high pressure discaling, water treatment for cooling blast furnace and rolling millsSewage treatment plant: During production of industrial water, filtration of take-off of the clear run can be used to save valuable drinking or well waterEnvironmental technology: Back flushing filters before waste water treatment plant (UV treatment, reverse osmosis, membrane filtration) Extends the lifetime of cartridge filters elements by several monthsMining: By filtering underground water of even quality is assured. This results in more reliable operation of pumps and disc cutting machinePaper industry: The protection of spray nozzles for screens of paper cutting machines. This results in fewer failures causes by clogging and wear.Automatic industry mechanical engineering machine tools: Cooling lubricant emulsions can be kept much longer in circulation. This eases the pressure on the environment and reduces waste-disposal and repurchasing costs. Filtering of cooling and service water protects cooling channels and pipelines from clogging.
