Reusing final effluent wastewater for applications such as irrigation of crops and even potable drinking water is now becoming a necessity for many water stressed locations around the world. atg UV Technology have invested in validating 9 multi lamp, ultra-high output low pressure amalgam UV Systems for water reuse.
Using the NWRI Water Reuse validation protocols, the world’s first validation standard for wastewater and water reuse, atg UV can now offer a range of solutions that will treat final effluent wastewater to an ultra-high standard, allowing for the safe and control rejection directly into the head of the drinking water works, without any environmental barrier.
The validated UVLW series features the very latest in low pressure Amalgam UV lamp technology and optimised UV chamber design to deliver amazing performance at a fraction of the size and operational power compared to standard low pressure UV systems.
Designed for municipal drinking water, the UVLW design is centred on the market leading 800 Watt Amalgam UV lamp that provides significant advantages over standard 200 Watt, 325 Watt and 330 Watt UV lamps.
Enhanced Variable Power: The 800 Watt Amalgam UV lamp features a specially design secondary control circuit that allows the UV lamp to run at operational powers of only 30% power. Compared to 330 Watt lamps which can become unstable and extinguish below 60% power, the 800 Watt Amalgam lamp will safely operate between 100% power and 30% power (70% turndown), providing significant flexibility to operators wishing to match the operational power of their UV plant to varying flow rates and seasonal water quality parameters.
Increased Lamp Life: The 800 Watt UV lamp includes a guaranteed useable lamp life of 16,000 hours minimum. Compared to the industry standard of 12,000 hours for Amalgam UV lamps, this feature allows operators installing the UVLW range to run their UV plant for around 6 months longer before scheduled maintenance is required. This extended lamp life makes the UVLW range one of the most OPEX competitive designs in the world.
Asymmetric Lamp Positioning: Through extensive CFD analysis and field testing, the UVLW chamber design matches hydraulic flow profiles with UV lamp intensity fields inside the UV reactor, eliminating the requirement for baffle plates and flow modifiers. This unique concept has allowed for significant improvements in disinfection efficiency, increasing treatment capacities by up to 30%, whilst using significantly less power and reducing head loss.
