What types of water treatment sand filters are there?

There are various types of filtration equipment in the water treatment industry. There are many types of water treatment sand filters. For example, there are very common sand mechanical filters.

This kind of equipment uses sand as a filtering medium. Under a certain pressure, it can pass turbid water through a certain thickness. Quartz sand is used for filtration, which effectively removes all suspended or colloidal particles and heavy metal ions in the water.

In addition to sand filters, there are of course other types of water treatment filters. Multi-media filters can handle turbid water and, of course, soften water. This device uses two different media as filtration.

The medium, especially in the industrial circulating water treatment system, is very popular. It can not only clean up the impurities in the sewage, but also can absorb the oil and can effectively meet the requirements of recycling. The filtering effect of this equipment is still very good.

Yes, it can clean up the suspended colloid and impurities in the water and effectively remove the sediment, but it will not eliminate tiny particles and bacteria. In addition to this equipment, there is also an activated carbon sand filter. The principle of this filter is The use of granular activated carbon can pass the residual organic matter or impurities in the water through the mechanical sand filter, providing very good conditions for the subsequent reverse osmosis treatment.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .
Bigger is not always better when it comes to pool pumps. A pool pump that is too large can hinder filtration and can even damage a pool’s filter and/or heater. It is therefore very important to know the size of a pool before purchasing a pool pump. If there is additional equipment (such as water features) installed into the pool, it will have to be taken it into account when deciding what size pump is going to be purchased. The more equipment is installed into a pool, the more powerful the pump needs to be.
It is important to consult with a pool equipment expert, such as Poolking's Pumps, before buying a pool pump. The team at Poolking will be able to give our customers professional advice regarding the size of the pump they will need to purchase.
