Understanding Sand For Sand Filters

At any time wondered if the fine sand in your sand filtration systems for the pool is equivalent to sand in a sand play package for children? Well the answer may surprise you. And is there a positive change between an above-ground or an in- ground filtering method for a pool? These are generally all good questions and we will cover them here in this article. Additionally, we will cover a few maintenance questions that arise from time to time as well. Silica Sand Malaysia

Hopefully we can shed some light on this subject of sand and see if we can clear some things up for you.

A fine sand filter works similar to how Mother Nature would it on her own by filtering out water that percolates through the surface. Rather than allowing drinking water to just percolate through the sand or surface to get clean as with Mother Nature, somewhat, water is forced through a cleaning system made up of sand to accomplish the job. 

The sand in a filtration system is not simply any sand that you can make up at the sand pile; it is created specifically to stop any particulates that are above a certain size. This is completed by the uniform gekörnt size of a pool sand filtration system.

Normally the average size of the sand particles is between 45 millimeters and 55 millimeters. Studies have shown that with this uniform size the yellow sand is able to acquire debris as small as 20 microns. And anything at all over 100 microns will cause problems with a sand filtration device so there are larger monitors generally found prior to the sand filter to keep them away from this portion of the system.

So if you have ever wondered where all this collected material moves because of this , that you, or a maintenance person, will have to back remove the system. This allows for the collected dirt that must be considered out of the yellow sand filter also to clean away the system. Over time the sand, just like on a beach will wear down and become too fine to do its job and will have to be substituted. In addition, if there is a lot of debris in a pool, from leaves or a harsh environment, such as a mud storm, oils, hair, the sand might not exactly manage to clean itself properly after back again flush and will must be replaced.

Careful notes of water pressure should be kept indefinitely so it is possible to discover subtle changes over time. When the sand filtering device becomes clogged, pressure will increase. Then a backwash will be required. If after completing a backwash process the pressure does not return to normal, then replacement of the sand media will most likely be required.

Consult with the manufacturer for the recommended pressure parameters. And keep an easy journal so that as time passes you will easily have the ability to see the changes that should come as the sediment transforms into a problem in the system.

In addition the periodic backwashing helps the program to operate at maximum efficiency. If the system is half blocked up then the efficiency goes way down. This kind of would be like generating around with the brake systems on, mileage suffers greatly.
