Activated carbon filters speed up the pace of sewage treatment

2023-03-24

Poolking

In recent years, lake water pollution accidents have occurred frequently in our country. Many chemical, petrochemical and other heavily polluting enterprises are built along the banks of major rivers, near urban drinking water sources and in densely populated areas. At present, these companies have completed the preliminary debugging of activated carbon filters, and also hope to more effectively improve the living environment throughout the day and speed up the pace of sewage treatment.

The design of the activated carbon filter is very simple, and the principle adopted is relatively common, but it has a very powerful sewage treatment function. The activated carbon filter uses stainless steel sintered mesh, which has strong corrosion resistance and pressure resistance, so the activated carbon filter can clean and filter a large amount of corrosive sewage at one time, protecting other equipment Corroded by sewage. Now the sewage discharged by factories and people around the lake must be cleaned and filtered by activated carbon filters before being discharged or reused.

The activated carbon filter can treat the polluted water resources of the lake, and it is also treating the source of the polluted lake. It can be said that it has achieved the goal of treating the symptoms and completely protecting the water resources. We all know that the outbreak of blue-green algae is caused by the eutrophication of water bodies due to the wanton discharge of industrial wastewater. Therefore, the chief culprit of blue-green algae outbreak is the discharge of industrial and domestic sewage.

Treatment of sewage can completely solve the problem of blue-green algae outbreaks, and the emergence of activated carbon filters has more efficiently protected the water bodies of lakes in our country.

9. What is the frequency to replace the silica sand of a sand filter?

----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.

1 .Why no water comes out when the pump is working ?

a. Power failure or motor protection tripped
b. Pump doesn't vent
c. Pump doesn't fill the water
d. Suction line/hose leaking
e. Transparent cover not properly installed - check filter basket - even bolts
f . Inlet suction process is too large g.) Total resistance loss exceeds the allowable range of the pump - recalculate the required pressure
h. Mechanical shaft seal leakage

5.Does a sand filter can use both silica sand and activated carbon together?

----Yes, they can. Silica sand is mainly used for filtration, while activated carbon is mainly used for adsorption. Silica sand is effective for higher water quality requirements. When use them together, silica sand should be placed on the bottom layer, and then activated carbon should be filled on the sand, but the cost of using two media is much higher.
