A DE filter filters down to the smallest particle size of 2-3 microns. To put things in perspective, a human hair is about 50 microns. Backwash water sourceFilter backwashing is generally used to remove suspended solids that have been removed in the media bed. On the one hand, self-sourced backwash uses water that is filtered through service filters, while the external source uses an external water source as a storage tank. Instead, your system has a feature called a multiport or sliding valve that allows you to wash the filter media, which in this case is sand.
Finally, the clean water passes through the valve and returns to the pool. The sand filters the water from fine debris, as it is packed in the tank and around the internal pipe. Usually, the tank is filled with sand about 60% of the way, so the amount you need depends on the size of your filter aquarium equipment tank. We’ll talk a little bit more about which sand is better to use a little later. If your pump makes a grinding noise, the filter may have pushed some of the sand into the impeller. Functional sand filters improve pump performance by removing dirt and stimulating a steady flow of water.
The required effluent concentration in the process flow can help determine the size of the filter vessel. The diameter of the ship may increase as restrictions become stricter for discharge permits. For more tips on finding the right filter, check out my top guide to pool filters.
However, to prolong the use of a filter, we strongly recommend removing large residues from the pool. It is best to sift through the water for some time to avoid clogging in the pipes. You have to think about the particles that the sand filter can remove. Well, it has a high capacity because the sharp edges of the sand can catch almost anything. So whether it’s a leaf or dead skin cells, the sand filter goes through everything.

Once at the top of the sand filter tank, the pool water passes through a distributor to ensure it is evenly distributed over the sand bed. The great thing about sand filters is that they can run for years without much maintenance.
This layer of water protects the top of the sand and the biolayer from the power of dripping water. It also keeps the biolayer moist, the biolayer will die if it dries out. Through 4 to 6 cm of water, some oxygen can reach the biolayer. But if there is more than 6 cm of water, the biolayer can die from lack of oxygen.

This helps to separate debris from sharp corners of sand. Due to the high pressure, the water carries the waste away and drains it through the drain pipe. In addition to the sand filters, you also see the cartridge filter, but the sand filter is the easiest to maintain. As a fairly economical option, pool enthusiasts have endorsed these filters.
