Water filtration sand is the sand used in filters as a media along with filter gravel
, filter coal, etc. This needs to be graded and of uniform size for the filter to function well. Its filtration quality is because of its texture which wears out with time called as breakdown rate. Filter sands with slow breakdown rate are preferred by users.
What to expect from manufacturers?
When water filtration sand is supplied, it should be hard and durable which increases the life of the filtration unit. An exporter who puts a lot of importance in testing and cleaning the sand should be chosen. Suppliers of filtration sand who deliver on time are always popular. Specifying the size and amount of filter sand required should be mentioned in the order. Always order from a company which has exelent quality control as it is very important to have sand of uniform size. The sand must be washed and dried to remove impurities that it may contain.
Custom filter sand sizes
Very often new designs require sand and filter gravels of a specific size which differ from the standard graded sand. Not all manufacturers provide you with water filtration sand that is custom made according to your specifications. Providing the manufacturer with samples of the size that your filtration unit requires will also be sufficient for them to come up with the required sand. Most suppliers also supply gravel in different sizes.
Filter sand uses
Slow sand filters are used to convert surface water into potable water and dont need the help of chemicals. These filters also require the services of a water filtration sand manufacturer. A very common use is in the swimming pool water filter. Backwashing is the method used to flush out the blockage. The filter tends to get clogged by solid material which has to be removed to improve efficiency. Custom sized water filtration sands are necessary for custom made filter units and if the manufacturer is careful with the quality and meets the standards, the efficiency of the unit will be considerably higher.
