AFS Cooling Tower Automatic Filtration System
AFS series self-cleaner, the advanced Automatic Filtration System design to stably and effectively control suspended solid in cooling tower circulating water in the effort of minimizing legionnaire’s disease, especially useful for the dusty environmental, and further reducing chemical usage needed for the system, saving energy and resources.
Working Principle
When the AFS filtration system is in operation, it will pump out a portion of the circulating water for filtration without disturbing the main circulation line. The impurities in the system are filtered through gradual and multiple cycles of interception, and finally removed from the system through necessary backwash. This design can effectively reduce the burden on the filter, improve filtration efficiency, and reduce operating costs.
1 Turbulator nozzles speeds up the water circulation, prevent impurities from settling and keep basin clean.
2 Filtered outlet water is distributed via turbulator nozzles into water basin.
3 Basin drain outlet connected with AFS for collecting sewage water into filtration system.
Benefits
Improve water quality and reduce energy consumption
Effectively remove suspended matter, impurities and some dissolved substances in water, significantly improve water quality.
Reduce scaling and corrosion, improve heat transfer rate and reduce energy consumption.
Equipment protection, prolong the service life
Further preventing algae blooms, bacterial growth and other problems in the water system.
Ensuring the stability of the water quality in the cooling tower can also prevent equipment failure and shutdown caused by the deterioration of water quality.
Reduce operating and maintenance cost
Reduce chemicals dosage of water treatment, reduce frequency of heat exchanger cleaning and prevent the failure and shutdown of equipment to reduce operating and maintenance cost.
Environmental protection, energy conservation and emission reduction
Reuse of recycled water and sewage pretreatment can save total water consumption, improve water quality and reduce the pollution of the environment caused by the direct discharge of sewage.
Features
Power Source
Centrifugal pump with stainless steel impeller, Large flow, high head, stable operation for driving fluid circular flow.
Solenoid Valve
Precisely controls the opening and closing of the filter pipeline, as well as the flow, direction and speed of the circulating water.
①The Primary Filter is an excellent pre-filtration device, efficient and stable solid-liquid separator which can be used in conjunction with ②The Secondary Filter that is large flow, high capacity for removing trace fine impurities in the liquid, to obtain better overall filtration performance, reduce filter material consumption and material emissions.
Control Center
Siemens PLC controller， automatically receiving, processing and executing various control instructions to ensure the normal operation and efficient filtration of the filtration system.
