Analysis of water treatment equipment replacing filter material need to pay attention to
Analysis of water treatment equipment to replace what need to pay attention to when 1, replace, quartz sand, activated carbon required 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 the customer to clarify, and record the running parameters, especially of quartz sand, activated carbon, feed water pressure.
3, 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, all the water to soak activated carbon.
4, 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 abundant moisture, air cleaning and internal gaps between the granular, make carbon granule not float in water, is also in order to save time.
Mainly in the charcoal filter at the bottom of the pot to put a few of the water, then put the active carbon into.
5, equipment shutdown: first of all, have a reverse osmosis to stop the reverse osmosis host pump, stopped the original water pump again, then closed the original water pump into the water.
6, admit quartz sand washed clean, original clean water pump activated carbon, is to wash first, then backwashing, wash to bright water colorless, no fine particles can be put into use.
Should be closed when activated carbon cleaning water softener.
After the 7, quartz sand filling, from the installed equipment.
Wash quartz sand, whether to admit that the valve opens before wash right is on the inlet valve and valve, inlet valve closed activated carbon.
Then the original water pump, is washed in the wash.
Then the positive and negative wash to replace.
Until the water make clear for waste water valve to come out.
8, in quartz sand before should also injected a few water in the sand tank, according to the large sand below, the order of the little sand in the above loading quartz sand, quartz sand filling volume is about 80% of the sand tank.
All the above is to introduce the content, hope to be of help.
