81. Top 10 Considerations When Converting To On-Site Hypochlorite 12/26/2013

    Transporting pure salt - the raw material needed to generate sodium hypochlorite onsite – is more cost effective, stable, and safer, than transporting and storing bulk sodium hypochlorite, or gaseous/liquid chlorine cylinders from local chemical suppliers. The conversion to on-site hypochlorite generation can be achieved by adhering to these design guidelines.

82. Boston Harbor Overhaul: A Water Cleanup Success Story 5/15/2017

    Boston Harbor used to be an icon of water pollution in the U.S. But a massive cleanup effort — one of the biggest restoration feats in the nation’s history — has revived the harbor in the last three decades.

83. How To Execute A Combined Control Strategy For Dissolved Oxygen 3/30/2019

    Maintaining dissolved oxygen levels by pairing smart controls with multiple blowers is emerging as a desirable method to address airflow requirements. Selecting the proper system and avoiding unnecessary complications are critical to successful implementation.

84. Trenchless Technology Poised To Advance Infrastructure Resiliency 11/23/2020

    As one of many ripple effects of COVID-19, capital investment in water and wastewater infrastructure is expected to see some setbacks due to reductions in revenue and cash flow during the pandemic. But a recent report highlights a brighter picture for the growth of trenchless technology in pipeline repair expenditures, thanks to its cost-effective approach for meeting pent-up demand.

86. What You Need To Know About Mixed Oxidant Solution 8/28/2019

    The main component of mixed oxidant solution (MOS) is chlorine and its derivatives hypochlorite and hypochlorous acid (ClO−, HClO). It also contains trace amounts of other chlor-oxygen species which work synergistically with the hypochlorite/hypochlorous acid to improve efficacy and performance. MOS is made from brine (salt) and energy, and is used for disinfecting, sanitizing and reducing the risk of infection due to pathogenic microorganisms in water and in other applications. It is particularly useful for customers who have specific challenges such as controlling biofilm or reducing disinfection byproducts exacerbated by biofilms.

87. HeadCell Eliminates Chandler, AZ's Punishing Grit Problem 2/1/2021

    Rapid population growth created the need for a plant initially designed for 5 MGD to expand four times over two decades to treat 27 MGD today. With no grit removal the plant struggled with grit since start-up, spending hundreds of thousands of dollars on contractors to remove accumulated grit every 2-3 years. The plant wanted to eliminate their grit problems once and for all. Tired of wasting money, time, and effort on this futile but necessary task, the plant hired Wilson Engineers to evaluate various grit removal technologies to determine which type of system would be capable of eliminating their grit problem.

88. Case Study: FMU90 Transmitter And FDU92 Sensor Provides Filter Control In Wastewater 8/10/2011

89. Refinery Expands Production While Meeting Discharge Standards Quality 8/5/2016

    Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

90. Corrosion In Wastewater Systems: More Than One Bug 8/31/2012

    The role of various bacteria in the destruction of concrete in wastewater systems has been recognized since 1945. Already susceptible to old age, wastewater infrastructure systems are also threatened by corrosive bacteria — but they needn't be. By Heather Ramsey, John Davis, and Gary Hall
