Water treatment equipment replacement filter material need to pay attention to the problem
Water treatment equipment replacement filter material need to pay attention to the question 1, replacing quartz sand, activated carbon needed tools: tongs, sand suction tube, tape.
2, replace the quartz sand, activated carbon, first to the equipment to conduct a comprehensive inspection, to see if the customer's equipment have already found no bad parts, if any should be timely to customers, and record the operation parameters, in particular, quartz sand, activated carbon water pressure.
Before 3, in quartz sand should inject a small amount of water in the sand tank, according to the large sand, below the little sand in the above order loading quartz sand, quartz sand filling volume is about 80% of the sand tank.
4, after the quartz sand filling, installed equipment.
Wash quartz sand, before washing to confirm whether the valve opening on the right is fill valve and valve, inlet valve closing activated carbon.
Then the original water pump, is washed in the wash.
Then the positive and negative wash alternates.
Until the waste water valve of water clarification.
5, equipment shutdown: first of all, have a reverse osmosis to stop the reverse osmosis host pump, stopped the original water pump again, then close the water pump into the water.
6, activated carbon loading volume is about 60% of the carbon filter tank volume.
In order to leave enough space of backwashing.
After loading the carbon carbon pot into the water, making water can fully soak activated carbon.
7, in sand carbon is generally: first in carbon again in sand, because, just loaded activated carbon, first to be soaked in water for, make its full wet, ruled out carbon granule and internal gap between air, make the granular not float in water, is also in order to save time.
First put a small amount of water at the bottom of the carbon filter, and then put the active carbon into.
8, confirm the quartz sand has been washed, the original water pump clean activated carbon, is to wash first, then backwashing, wash to water colorless, no fine particles can be put into use.
Washing the activated carbon to shut off the water softener.
All the above is to introduce the content, hope to be of help.
