We have a wide variety of materials for water filtration and treatment, for domestic and industrial uses, and very diverse applications ranging from sediment retention to iron oxidation. Among these are sand, silica gravel, anthracite, garnet and activated carbon, resins and others for more specific applications, such as removal of certain contaminants.
Sediment retention
Zeolite: A high-surface, irregular aluminosilicate mineral that provides exceptional sediment removal, improving the capabilities of traditional multimedia (or deep bed) technology. It provides filtration down to 5 microns, operates at velocities up to 15 gpm/ft2, and is capable of retaining up to 80% more sediment before requiring backwashing. It can be used in pressure tanks and gravity filters. It is sold in 1.0 ft3 bags.
Anthracite: Very hard mineral coal used for many years in water treatment, especially in municipal plants, combined with silica sand to form dual beds. It is also the first component of multimedia (or deep bed) filters. It is sold in sizes #1 and #1.5 in 1.0 sq. ft. bags.
Silica sand: This is one of the first filter materials used. It is still the standard in pool filters and the second component of multimedia filters (or deep bed). It is sold in 50 kg bags.
Garnet: mineral of very high density and hardness, characteristics that allow it to be used in very fine granulometries, remaining in the lower part of the multimedia filters after backwashing. It is the third component of multimedia filters. It is sold in 22.7 kg (50 lb) bags.
