Facilities of the unique place, compact structure of the preset closely, functional diversification, superficial, filtering effect is good, can complete topped self-cleaning filtration, helps to reduce the suspended solids content of raw water, and the use of special material, use fixed number of year long survival.
Office principle, is to wash facilities: what are washing filtering that is normal.
Valve to change is to wash the azimuth, sewage through the booster pump to increase pressure on this later be sent to the sand filter valve, through multi-channel valve switch, water through the sand from the water after the hat, from its center to the upper, and finally from the discharge outlet.
Backwashing: backwashing is also very simple, only need to change the valve to the azimuth backwashing.
Basic operation process is the same as the above steps, the water from the bottom of the sand washed up, bone, the sand layer so you can put the accumulated pollutants washed away, finally from the discharge outlet.
Operation: principles and before washing, backwashing are the same, because they can complete the multi-way valve switch, the water will discharge from the outlet.
Filtering: first, turn the valve to the orientation of the backwashing water will pass through inlet core rod inside the facilities from down to up flush again, dirty water from the drainage outlet discharge.
15 minutes after this again to switch the valve to is the orientation of the washing, water will from the inlet, from the leadership of the filter material flowing downwards, so the rest of the dirty water from the discharge outlet.
The whole process takes 10 -
About 15 minutes, at the last turn the valve to work orientation, filter facilities running regularly and scour, principle and the previous description are the same.
