A sand water filter has different functions. It is a filter made out of sand that helps to get contaminants out of water (H2O), including sand itself and particles similar to it. They are composed of many levels of gravel and sand that ultimately become more fine. It is ironic that sand is one of the substances that the filter takes out of drinking sources. The technology employed to make these items is over one hundred years old, and the filters are more commonly used in less developed nations today.
These filters are known for removing solid particles out of drinking supplies. People who get their water from municipalities do not need these items, as city departments already perform this function. It is people who get their supply from a private source, such as wells, who would get the most use out of a sand filter. If a homeowner’s well H2O supply is thoroughly tested to be free of debris, then a sand filter would in fact be all that he or she needs.
Sand filters are not constructed to clean water that is tainted with tiny particles. These are the types that can not be seen within a clear container of liquid. Other than in the situation of a natural drinking source, this type of filter would need to be used in conjunction with another one. In a lot of cases, the second filter also needs to take out particulates, which are tiny particles not visible to the human eye.
One of the best uses of a sand filter is for a swimming pool. They are a lot less costly than cartridge filters are. Nonetheless, while some money will be saved when the initial purchase of the filter is made, having a sand filter can very well result in a higher bill for water each month. This is since it takes more H2O to clean and wash such a filter than it would otherwise.
For homeowners with pools which are near trees, a sand filter is their best bet. The dirt from the surrounding area can more easily block up cartridge filters. This would require cleaning the filters a few times each week, which can get both tedious and expensive after a while.
In conclusion, sand filters have been around for over a century. They are ideal for filtering out contaminants from wells and swimming pools, though they can lead to bigger H2O bills where pools are concerned.
