Harmsco WG WaterGuard Filtration System combines several filtration technologies with Ultra Violet (UV) sterilization providing a fail-safe unit that continuously improves the water supply by acting as a multi-layer filter, adsorber and sterilizer. This product is designed with a patented Up-flow technology which prevents the accumulation of air inside the filter housing keeping the filter operating at 100%. The family of Harmsco's Waterguard™ Water Filters consists of three models, 4, 8 and 12 gpm , and selection is based on the flow requirement. For example, the 4 gpm model, HS-4, is intended for a single bedroom, single bathroom application. The 8 gpm model, HS-8, is for a two bedroom/two bathroom application, and the 12 gpm, HS-12, for a three bedroom/three bathroom. The filters can be plumbed parallel for greater flow rates. All three WaterGuard™ models incorporate Harmsco's patented Up-flow technology to evacuate the chamber of air and maximize the cartridge's effectiveness. Briefly described, water enters the housing and must first flow through all layers of the cartridge, rise to the top of the cartridge chamber, and then into a standpipe that leads downward to the UV reactor. Each model consists of a pressure vessel with two chambers , an upper cartridge filter and a lower UV reactor, that are internally plumbed together. The upper filter chamber contains an advanced filter cartridge element, and is accessed through a secure closure. The lower compartment contains two UV lamps∗ inside quartz sleeves that are seal mounted to the housing's sidewall. The lamps are accessible through simple fittings that engage the quartz sleeve mounts. |

Pressure drop shown is for housings with Flow Restrictor and Cartridge in clean water. The Flow Restrictor (installed in outlet) is responsible for 70% of pressure drop and is a requirement of NSF 53.
ULTRAVIOLET LIGHT AND MICROORGANISMS
Ultraviolet light has been used and accepted as a disinfectant for years. Microorganisms, such as Escherichia coli, Salmonella typhi, and Hepatitus A virus, are lethally affected when exposed to UV. However, not all species react to the same extent, and conditions vary depending on the UV intensity and time (UV Int. x Time = dose). Some microorganisms require such a very high dose of UV to be effective that filtration is still the recommended and most feasible means to disinfect. It is for these reasons that Harmsco has developed the WaterGuard Water Filter that utilizes a multi-technology, flow-through barrier cartridge filter, and a powerful ultraviolet disinfecting reactor, in one convenient appliance.

Layer 1 The first layer is a pre-filter to catch any sediment or scales that may have migrated downstream from the water source. Layer 2 The second layer consists of high quality activated carbon which is considered by many to be the world's best adsorber of unwanted chemicals, such as disinfection by-products. It also reduces chlorine while improving taste, smell, and the overall aesthetics of the water. Layer 3 The third layer is a cyst rated filter∗media which provides a barrier to cysts. The fine filtration ability of this media also reduces the turbidity of the water prior to the UV application.
