            The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration. The coarser sand in the rapid filters has larger voids that do not fill as easily.
            The gravel installed under the sand layer(s) in the filter prevents the filter sand from being lost during the operation. The under-gravel also distributes the backwash water evenly across the total filter. This under-gravel supports the filter sand and is usually graded in three to five layers, each generally 6-18 inches in thickness, depending on the type of underdrain used.
            The Anthracite Filter Media is thoroughly selected from anthracite which yields the highest percentage of carbon. It is then hydraulically classified to reduce mineral matter and ash to a minimum, and finally screened and washed to ensure suitability for filtration purposes.
            The Activate Carbon adsorption has numerous applications in removing pollutants from air or water streams both in the field and in industrial processes such as:
Spill cleanup
Groundwater remediation
Drinking water filtration
Air purification
Volatile organic compounds capture from painting,
dry cleaning, gasoline dispensing operations, and other processes.
            Light yellow to golden global granule, used in water purification, extracting uranium, metal separation and purification.
