Anthracite is a very effective and excellent density media filter. When compared to equivalent filter sands, it has longer filter run and service flow, reduced backwash rates. Because of its unique density, it can be easily combined with other filtration media.


Sand and Gravel water filter sand is composed of hard, durable, and dense grains of siliceous material. Our Sand and Gravel ’s physical properties make it among the finest available in the world for filtration applications.


Glass filter media is more efficient: Saving on backwashing and the resultant water, energy and chemical treatment costs. - It generally removes finer particles from water than the equivalent grade of silica sand. -With superior permeability, back washes take less time, saving water/sewer charges, and energy and chemical treatment costs. - Glass filter media keeps cleaner: It's less susceptible to bio-fouling as, unlike silica sand Glass media's particles have a smooth surface area, so bacteria can't get trapped in any cracks or flaws, which translates to less remedial action and again less chemical treatment to kill pollutants. Glass filter media requires less material: It's less dense than sand, requiring 10% less media to fill the equivalent filter. Glass filter media doesn't degrade: It therefore has a longer file span and may not need changing even when the filters are due for refurbishment.


Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment. Adsorption is both the physical and chemical process of accumulating a substance at the interface between liquid and solids phases.
