Vitreous filter medium GLASS

· Filter media environmentally friendly made from glass recycled. 25 kg bag. ·Glass filter media is more efficient: Saving on backwashing and the resultant water, energy and chemical treatment costs. -It's angular to sub-angular particle shape and bound silica content provides a 30% improvement in turbidity removal over silica sand. -It generally removes finer particles from water than the equivalent grade of silica sand. -It's non porous composition means its less likely to ''clump'' or channel than 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.
