f. Ultraviolet radiation sterilizer and terminal water pump inter-lock and will start and stop in-phase.
e. PH adjust metric pump and the second step high pressure pump inter-lock. They will in-phase start and stop.
in phase.
d. Flocculant filling metric pump and raw water pump interlock. The two pump start or stop
c. The first step and second step reverse filter are all collocated with pressure switch. When the pressure is too high the corresponding pump will stop.
b. High pressure pump is collocated with pressure switch at in-let and our-let. When the pressure is too high, the pump will stop. And when the pressure is too low, the pump will automatically running.
a. Raw water tank, middle water tank, terminal water tank collocating with liquid position controller which can send the signal to water pump to prevent the water height is too much and prevent the pump from absorbing air.
1.3.3 Other Automatic control scheme
c. The second step reverse filter. There also is conductance meter at in-let and out-let which can observe the conductance of water at any time.
b. The fist step reverse-penetrating. There is conductance meter at in-let and out-let which can observe the conductance of water at any time.
a. The system has relevant flow-meter and pressure gauge. They can show the working water volume and pressure immediately.
1.3.2 Instrument scheme
b. Reverse filter device use PLC program controller. Need to wash the film every 2 hours in order to prevent the surface of film from polluting. This measure can effectively prevent the film from polluting and can prolong the lifespan of film. The reverse filter device has a set of chemical washing system. Please wash the film of reverse filter termly by this washing system.
a. Precision sand filter, active carbon filter have a set of UPVC material manual operation valves which control running and reverse washing.
1.3.1 Running and operation mode
The pure water system is half-automatic running and the reverse filter device is automatic running. Details as following:
