Self-cleaning filter for cooling water

Self-cleaning filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water body, reduces turbidity, purifies water quality, reduces system dust, algae, rust, etc., so as to purify water quality and protect other equipment in the system from normal Precision equipment for work. When the pressure difference of the self-cleaning filter reaches the preset value, the automatic cleaning process will begin.

During this time, the supply of clean water will continue to flow, the cleaning valve will be opened, and the water pressure in the cleaning chamber and the sewage suction device will drop significantly. The pressure difference of the pipe produces a suction force between the sewage suction pipe and the cleaning chamber through the suction nozzle, which constitutes a sewage suction process. The combination of the axial movement and the rotational movement of the dust collector cleans the inner surface of the entire filter screen.

The blast furnace gas cooling water of the steel plant has high impurity content and large flow rate, and the filtering effect is not good, which not only causes the wear of the slag flushing water pump and the heat exchange water pump to increase, but also has a serious impact on the operation of the cooling tower equipment behind, resulting in huge losses.

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.
Poolking’s sand filter warranty is 3 years for fiberglass filter,2 years for plastic filter.During the warranty period,if the filters parts have any damage,we can judge the factors according to the photos or videos, then we can offer free parts to replace. If the filters are damaged badly,we will provide a new one.
The pumps and lights are 1 year warranty,the method is same as filters.
---Poolking has a professional Quality Control team to guarantee each product is 100% inspected before packing. For example when the filter inner tank comes out, they will make a first water testing before bobbin wounding. After installation all the connections or manhole & sightglass, they will make the second water testing. During the packing procedure, QC team will inspect all the details like wounding, neck, internal resin and so on to make sure no leaking and without flaw.
----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.
