1. After the system has been shut down for a long period of time, when it is reopened, it is necessary to wash the filter material for about 5 minutes, and rinse it until the water is clear.
2. When the system runs for the first time or after a long-term outage, use a spring washer to vent the equipment: Open the exhaust valve, the inlet valve, and then fill the water until the exhaust valve V8 discharges water without air. (Part of the small filter There is no spring washer to set the exhaust valve separately, you can use the outlet to exhaust.)
3, for large filters, air scrubbing can be used to enhance the effect of backwash, generally open into the compressed air (intensity 10-18 l / s.m2), and then gas-water backwash.
4. When the equipment is backwashed, the pneumatic valve should be controlled to make the backwashing strength, and it should be avoided that activated carbon leaks out of the system.
5. According to the condition of the influent water quality, the active fuse carbon filter should be replaced at regular intervals, and it should be changed once every 3 to 6 months.
