The Aquamerik filtration sands and gravels are composed of whole grains silica crystalline of a great hardness. They are durable and dense, which enables them to be resistant to degradation and gives efficient results. Used for building observation wells, pumping wells, extraction wells and other installations with PVC screens.
All sand grades are washed, dried and classified according to the most strict SPC quality control programs and QIP quality insurance program. Moreover, our sands and gravels meet AWWA B-100, ANSI and NSF-61 standards for filtration medias. These sands can also be used in the systems of industrial and municipal drinking water filtration. Shipped in 50, 55, 88 and 100 lbs bags, 3000 lbs available upon request.
