Does the use of diatomaceous earth in a sand filter destroy the sand's ability to filter?
huh...i'd try using sand in the sand filter and DE in a DE filter for optimum results. A: Yes, D E can interfere with the sands ability to to it's job.

Diatomaceous earth is the fossilized exoskeletal remains of tiny diatoms. When the filter pressure rises, the filter is backwashed like a sand filter, It then has to be "recha…rged" with more DE powder. Normally it is poured in a slurry into the skimmer which then coats the filter grids.
No, it'll blow right back to the pool which will then make it hardto remove. Sand filters REQUIRE a #20 grid pool filter sand. Thereis also another product possible called zeo…lite for sand filters...it will filter finer than sand.
It depends on how large the filter is.
You can use silica sand in a sand-type filter (only).
The most common sand used in pool filters is #20 silica sand.
Many, many things. It, used in livestock feed, for pest control in lawn... but mostly in feed.
Basically in a nutshell, diatamaceous earth is a very fine powder that is derived from ground up fossilized remains of extinct animals. Inside a d.e. filter(short for diatamac…eous earth) it consist of devices we call grids. These grids can be various lenghths and widths depending upon the manufacturer. A common filter, for example, is a 48sq ft made by Pentair. In this particular set up, there are 7 full grids and one partial grid. Each grid is 24" high and is slightly curved. The width is about 10 to 12 " counting the roundness of the curve and 6 to 7 " for the partial grid. Each grid has a ribbed skeleton of plastic and is covered by a web of cloth, similar in consistancy with cheese cloth. The powder coats this cloth making each grid a filter in and of itself. The water is pushed thru this powder and cloth by the pump, goes into the inside of the grid and is forced out of the top of the grid thru a hole that is attached to what we call a manifold in the top of the filter. Then the water returns to the pool filtered. After a while of collecting dirt and debris you have to do a process called backwashing. You know its time to backwash when the pressure gauge reads too high. (consult the manufacturing specs on your system to know what that reading should be) When you backwash, you typically change a valve setting and let the system run for a couple of minutes then return the valve setting back to its normal filtration mode. ALWAYS shut off the pump each time you change the valve setting. In backwashing, it reverses the flow of water thru the grids and drives the dirt out of the filter thru a bottom drain built into the plumbing. Most cities have ordinances that make the drain to be plumbed into your sewer system, however in some rural areas some people let it run out into the back yard. after backwashing you have to recharge the system with fresh d.e. This can be acomplished by taking a scoop or two of the powder and pouring it into your skimmer that is closest to the pump while the pump is running. What happens then is the d.e goes into the filter and recoats the grid with new, clean d.e pwder. Exactly how much d.e you put in, depends on the size of your specific filter.
It is important to use the right size sand for a sand pool filter. It is usually a .45 to .55mm sand which is available at any pool store or pool service company.. Do not use… play sand from as it is too fine and will not work well and will most likely just end up in the pool. Sand has to be big enough not to go through the filter laterals. This is the part of the filter that stops the sand but allows the water to flow.
Most definitly. I had a salt water system installed in March of 2008. and still use my sand filterit works great. No problem at all. I use inexpensive water softener salt, 40l…b bag, I try and keep a record of my system reading and keep it within the original settings that was in use when it was set up. The water is like smooth diamond. Crystal clear. The only thing I had to do was backwash to clear out the pollen and leaves. After that I added salt, about 2 bags, after I shut the generator off for about 24hrs. Then turning it on and checking the readings. WoW This is a great thing. Less work and more Play. Let me know how you come out. Enjoy.
\n. \n. \nThe instructions for the amount of sand to use with your filter should have come with your filter. If you threw those instructions away and removed the sand from y…our filter to replace it, there may or actually should be a mark on the inside of your filter to indicate the level for the top of the sand. It will be fairly near the top. You should only need to remove the top two inches or 5 centimeters of sand about once a year, and then replace it. Otherwise you should backwash your filter. That means, you use the outlet as the inlet and wash the stuff in the filter out the drain or into the yard until it runs clear.
This is a bad idea. Diatomaceous earth (de) will go right through a sand filter. It will end up back in the pool and then it is almost impossible to get out. Sand goes in sand… filters, de goes in de filters.
\nThis will absolutely not work.
In Science Experiments
Diatomaceous Earth is used as an organic insecticide, as a flea treatment, and as a wormer.
In Food Science
Of course it can, it is one of the best oil filters available. Do not use the oil for anything other than fuel in your bio-diesel vehicle. After you filter the oil you can… use the diatomaceous earth in your mulch pile, it will help in the breakdown of the fibrous vegetation.

Sand can be used in a filter that is made up of a box, with an "in" and an "out" pipe connected to it. Inside the box, there could be 2 bits of filter paper, similar to that f…ound in a coffee maker (to stop the sand escaping), one covering each pipe. The sand would be between these 2 filters and, due to the porous properties of sand, and the fact that it lets very little solid particles through, it would filter the water to some degree, however, carbon is more commonly used, as it can filter out much smaller particles.

Diatomaceous earth is a fossilized skeleton that dehydrates organisms such as parasites, and insects that come into contact with it. Chickens will use it to give themselves du…stbaths to kill lice. Most often humans use it to deter or kill pests pests from a dwelling or to keep insects out of or away from produce containers. . It can be used along baseboards to keep centipedes and coach roaches at bay. It is used commercially in agriculture around boxes of produce to prevent insects from infesting boxes of produce. Diagomaceous earth can be added commercially to flour to prevent insect eggs from hatching.
