Sonitec's Vortisand water filtration system uses centrifugal force (vortex effect) in combination with sand filtration to treat water used in cooling towers and chilled or hot water water loops in HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. systems. It can also be used in graywaterWastewater from a building that does not include flush-water from toilets and (as most commonly defined) water from kitchen sinks or dishwashers. In some places, graywater can be collected and used for subsurface irrigation. recycling systems and for rainwater polishing for toilet flushing and other applications. The Vortisand spins untreated water above the sand media, forcing large suspended solids to accumulate on the wall of the tank. With these larger particles removed, finer sand can be used in the filter media, improving filter performance and longevity. The Vortisand removes more than 90% of suspended solids to 0.45 micron, filters up to 20 gpmGallons per minute. Measure of liquid (usually water) flow./ft2 of filter media surface, and reduces backwash water usage by 25-50% over typical down-flow filters, according to the manufacturer. The silica sand in the filter needs replacing every seven years if properly maintained. The filter system vessel has a five-year warranty and the filter manifold and external equipment a one-year warranty. Sonitec's U.S. facility is located in Holyoke, MA.
