Significant innovation had occurred in the 17 years since the TrojanUV4000™ was installed at the Murfreesboro Water Resource Recovery Facility. Advancements associated with system efficacy, simplified maintenance, and energy efficiency had been introduced, all of which correlate to cost savings. Such advancements can all be found in the TrojanUVSigna™ – the UV system that was selected for the upgrade.
After a 17-year run, a plant’s UV disinfection system was limping toward the finish line. The city needed to identify a replacement UV system that fit into the same channel, offered lower power consumption, and contained a practical ease of maintenance to reduce the amount of labor consumed on the equipment. The new system requires dramatically less power to run while simultaneously streamlining upkeep.
The water treatment plants (WTP’s) manager for the city of Midlothian, TX reports significant reduction in chemical costs, gaining new management control for their generation and feed equipment, and ending a pesky maintenance burden, by switching to three-precursor vacuum generator-feed, from batch-generator-pumping, for introducing chlorine dioxide (ClO2) into their 8 MGD plant #2. As a result, he plans to make the same change at their 12 MGD plant #1.
The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant’s management team became interested in pursuing the gas-to-energy power co-generation system for both environmental and cost reasons.
The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.
Fairmont, Minnesota, known as the City of Lakes, is located in Martin County in southern Minnesota. The city’s water treatment plant serves a mix of customers including approximately 3,900 residential taps, 500 commercial and 17 industrial customers. Looking to the future, Fairmont city leaders began to investigate upgrading the city’s water treatment plant in 2010. The existing plant had been in operation for well over 70 years and relied on gas chlorine for disinfection.

Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.
A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.
The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
