AFP Non-Contact Disinfection
Dry Lamp Design
AFP™ Non-Contact Disinfection systems by ENAQUA are diametrically opposed in design to every other municipal UV disinfection system on the market. Unlike traditional systems, the ENAQUA systems do not have their UV lamps surrounded by fragile and fouling-prone quartz sleeves. AFP™ Non-Contact systems have their water flowing through the inside of Activated Fluoropolymer™ tubes, with the lamps on the outside – always dry. In traditional quartz UV systems, water flows through an open channel with the UV lamps submerged within the channel. AFP™ Non-Contact systems feature banks of “dry” UV lamps surrounding water conveying tubes, such that each tube gets exposed to ultraviolet light from all sides. This eliminates the need to interrupt or remove any hydraulic seals during any lamp maintenance. In fact, the AFP™ tubes need never be replaced or removed from the system.
AFP™ Non-Contact Disinfection systems do not flow water in a typical “channel”. The flow takes place in a series of circular tubes, leading to a very smooth internal surface. Also, unlike traditional channels, they are naturally turbulent and plug flow in nature. This design makes it easy to predict and monitor the systems performance as well as provide for scale up – all designs are modular.
The UV lamps in ENAQUA’s systems are outside the flow of water. This allows for the use of conventional Low Pressure High Output lamps instead of the proprietary and expensive “Amalgam ”lamps used in traditional quartz-based UV systems.
Easy Upscaling
The modularity and simple design of the AFP™ Non-Contact Systems enable simple scale up from as small as 0.028 MGD (1.26 l/s) to as high as 31.68 MGD (120,000 m3/day) in a single reactor with little or no flow variation between the tubes. This feature, unlike traditional channel based systems, make ENAQUA’s AFP™ Non-Contact systems unique and without peer in the industry. The basic system designs are also the same whether installed in a channel or as an in-line piped system.
