Wastewater Disinfection Resources

  1. Water Resource Recovery Facility Replaces Its Aging UV System - Murfreesboro, Tennessee 6/14/2018

    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.

  2. UV System Saves Energy And Reduces Maintenance 2/21/2018

    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.

  3. Emerging Trends In Disinfection: Peracetic Acid 1/24/2018

    As regulations on chlorinated disinfection byproducts and total residual chlorine become increasingly stringent, peracetic acid (PAA) is gaining in both interest and usage as a water reclamation disinfectant. Here’s what you need to know.

  4. Change To 3-Precursor Vacuum Generator-Feeder For ClO2 In WTP, From Batch Generator Pumping, Cuts Chemical Costs, Gains Plant Management Of Equipment 1/22/2018

    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.

  5. Wastewater Plant Relies On Thermal Flow Meter For Co-Gen Power Gas Blending Process 12/18/2017

    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.

  6. Fluence's MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs 10/26/2017

    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.

  7. Treatment Plant Upgrade Includes Conversion To On-Site Sodium Hypochlorite Generation To Ease Operations And Increase Safety 9/15/2017

    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.

  8. Need More Water? Think Ozone-BAC For 'One Water' Resolution 8/25/2017

    If you thought reverse osmosis was the one and only choice for potable water reuse, think again. Ozonation followed by biological activated carbon (ozone-BAC) is more suited to inland communities and may be better at removing chemicals of emerging concern (CECs).

  9. Why India Needs More Wastewater Treatment Plants 8/3/2017

    As India hurtles towards a more developed economy, one of the casualties has been the deteriorating state of our environment. Rapid industrialization has, unfortunately, hiked up the number of pollutants in our surroundings. One of these pollutants is wastewater. Management of wastewater through wastewater treatment plants in India has become an imperative of our cities today.

  10. Packaged Wastewater Treatment For Uneven Terrain 7/31/2017

    Storey County, NV, just southeast of Reno, needed to replace an outdated wastewater treatment plant that serves the historic communities of Virginia City and Gold Hill. The new site was on the side of a hill, presenting challenges for the design of the plant and the orientation of its processes. Also, the new plant area was entirely within a district on the National Register of Historic Places. Read the full case study to learn how the new modular design allows for an efficient wastewater treatment solution.
