Differential Pressure Automatic Backwash Filter For 100 Micron Irrigation System
Automatic Backwash Filter Filtration Process
1, The discs are compressed together by both the spring and the pressure difference on the tightening cap, forming a sturdy filter element preventing solids breakthrough.
2, Inlet water flows into the filter through the filter element
3, The suspended solids in the water are trapped on and between the discs
Automatic Backwash Filter operating system:
Cooling circulating water system, agricultural irrigation system,
steel high pressure descaling system, fire sprinkler system, UF/RO
membrane system protection filtration, seawater desalination RO
protection filtration, high concentration wastewater treatment,
river, river, lake process water treatment, aquaculture Filtration,
water/rainwater reuse treatment, wet electric dust removal ash
water treatment, spray paint wastewater treatment, automobile
assembly test, cutting fluid circulation filtration, tire rubber
cooling water filtration, oil recovery water injection filtration,
marine press water reuse, water source heat pump Cooling water
filtration, waste heat utilization filtration.
