24 hours Continuously Filtration Automatic Backwash Filter
Automatic backwash filter applied to a variety of water supply systems, process water systems and industrial cooling water system, especially for a 24-hour non-stop operation system, you can filter impurities in the water all kinds of machinery, equipment, systems to ensure safe and reliable operation
Technical feature
1.A high filtration precision, water quality and stability.
2.Through its own retrieval and response function, automatic backwash can cope with the instability of the water quality fluctuations, without human intervention.
3.Control system is responsive, precise operation, differential pressure and time setting function can be flexibly adjusted according to different sources of water and filtering accuracy backwash pressure or time settings.
4.Cleaning efficient and thorough, the filter could completely restore the initial state, and thus life, without replacement.
5.Backwash without interrupting the normal production of water in continuous operation, stable and reliable.
6.The backwash short duration, backwash water consumption is only 0.001-0.002% of the normal water production, water-saving, energy saving, energy conservation.
7.The structural design of reasonably compact, small footprint, flexible installation of mobile.
8.Equipment vulnerable small, no supplies, low operation and maintenance costs, simple operation and management.
9 wide applications, suitable for different raw water quality and water requirements.
Water enters the filter through the "Inlet" . The water then reaches the fine screen, which purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen.
As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen and its external section.
Cleaning Process
When the difference in pressure reaches the preset value on the electronic control unit, a series of events is triggered while water continues to flow to the system units. The flushing valve opens, pressure is released from the hydraulic piston, and water flows outside. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered, and the dirt collector nozzles begin a suction process. The water flows through the hydraulic motor, which rotates the dirt collector around its axis. The pressure released from the piston and the high pressure inside the filter, cause linear movement of the dirt collector. The combination of the linear movement and rotation significantly cleans the whole internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle and the increased water pressure returns the system to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the "Outlet".

Application Fields
Application
Power Plants : Treatment of Industrial Water for cooling generators and filtration of sealing water to increase the service life of the Turbine Shaft sliding-ring seals in Hydro-Electric Power Stations.
Steel Industry: Protection of nozzles and pumps during high-pressure descaling, water treatment for blast furnaces, rolling mills, cleaning, quenching applications.
Chemical Industry : Improvement of product quality by filtering process media. Filtration of White water, Black Liquor, Starch, Fuel oils, Caustic Solutions, Cooking oils, brackish/salt intake water etc. For filtration of water used for cooling, process, fire protection applications.
Pulp & Paper Industry : Removal of fibers from white water filtrate, Protection of spray nozzles for screens of paper making machines. This reduces frequent failures caused due to clogging and wear.
Mining : By filtering underground, spray water of even quality is assured. This results in more reliable operation of pumps and disc cutting machines
Environmental Technology. Used as pre-filters before waste water treatment plants, UV Treatment, Reverse Osmosis, membrane filtration etc.
Sewage Treatment Plants : During Production of industrial water, filtration of a take off of the clear run can be used to save valuable drinking or well water.
Heat Transfer / Heat Supply : Protects heat Exchangers from clogging & wear
