Wastewater Disinfection Resources

81. 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.

82. 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.

83. 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.

84. 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.

85. 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.

86. 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).

87. 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.

88. Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility 5/1/2017

    A Leopold filter system helped save the North Columbus Resource Facility approximately 1,000,000 gallons of water per day that was previously used for backwash purposes.

89. Compact Footprint And Flexible Hydraulics Ease Initial Expansion, Leave Room For Future Growth 4/11/2017

    When Plainfield, IN, needed to double their permitted capacity from 2 MGD to 4 MGD at their South wastewater treatment plant, they faced a dilemma. Like most treatment plants, space is at a premium, and compact design was needed not only for the current expansion, including the addition of a post aeration structure, but to preserve as much room as possible for projected future expansions.
