As a sterilizer áFor ponds up to 4400 gallonsá Flow rate up to 3675-gphAs a clarifier á For ponds up to 9000 gallonsá Max flow 4500-gphUV is versatile technology used for disinfecting water, other opaque liquids, hard surfaces, and air. Using the same germicidal rays as the sun, but hundreds of times stronger UV offers a reliable, cost effective, environmentally friendly alternative to chemicals and their resulting bi-products. UV Sterilization is a purely physical process, not a chemical one, so it doesn't alter water's chemistry, taste, smell, or pH.Aqua Ultraviolet manufactures UV sterilizers for medical facilities, pharmaceutical production, municipal reclaimed water, aquaculture, and drinking water. We also produce a full range of units for residential and commercial aquariums, swimming pools, and ponds. As an innovator in the industry our designs result in a maximized UV dosage allowing for equipment with a smaller footprint that efficiently treat higher flow rates.
