Drinking Water Case Studies and White Papers

41. Replacement Of Gas Chlorination System: City Takes Advantage Of Special NaOCl Dosing Unit 4/5/2012

    Operations management for a municipal direct water filtration plant reports achievement of a reliable and cost-effective change in chlorination systems that has continued to provide for effective disinfection, while better meeting safety and efficiency criteria. By Cliff Lebowitz

42. Four Day Pilot Study For Iron And Manganese Does The Trick (Loprest) 10/2/2018

    The City of Southgate, California wanted to investigate the effect of replacing the existing media in their Well 27 treatment plant. The plant would not reduce the incoming manganese levels to below the 50 μg/l MCL. It has been theorized that the existing media has become fouled beyond cleaning during the one year plus of non-operation while contained in the filter tank full of water. That environment could produce a likely source of biological and other sources of fouling.

43. Energy-Efficient Blowers Help Clean Riachuelo River 9/14/2022

    Cleaning tannery effluent is an energy-intense process. The Curtidor Industrial Park (PIC) has found a way to keep energy usage and costs down while reducing pollution in the Riachuelo River.

44. Durable Screen Line Expanded To Meet Vertical And High-Flow Applications 11/18/2020

    Water and wastewater plant operators often encounter challenging screening situations that aren’t well served by conventional products. This includes deep channel applications, where space is very limited, as well as high-flow applications. To address these growing demands, Parkson recently expanded its Aqua Caiman® line to include the Aqua Caiman® Vertical and Aqua Caiman® HD.

45. Delivering Intelligent Connectivity To Prepare For The Next Decade 9/28/2020

    From aging infrastructure and coping with natural disasters, to an increased desire to incorporate renewables and optimize the network, utilities and communities continue to adapt to the macro effects in play today. Now more than ever, we have a collective opportunity to find new ways to innovate and demonstrate resiliency through technology.

46. FEDI Solution For Sohar Refinery Project 1/1/2016

    Orpic (Oman Oil Refineries and Petroleum Industries Company) required a thermal seawater desalination solution as part of its Sohar refinery improvement project to ensure an uninterrupted supply of fresh feed water to for its boilers.

47. On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank 5/7/2019

    Purissima Hills Water District (PHWD), a county water district, provides chloraminated water service to two-thirds of the town of Los Altos Hills, adjacent to the city of Palo Alto in Northern California. With remote tank locations, low population density (6,800 people) and low water demand (1.61MGD), PHWD is constantly challenged to maintain consistent disinfectant residual levels while simultaneously balancing the safe delivery of chemicals to its tank site at an affordable cost.

48. Setting The Standard for Effective Chromium-6 Treatment 6/26/2017

    When California capped chromium-6 in drinking water at 10 ppb in 2014, it became the only state to set a chromium MCL and, in so doing, created a challenge for water providers across the state.  WRT (Water Remediation Technology LLC) has met that challenge with the SMR™ (Selective Metals Reduction) Process.

49. City Of San Diego Water Plant Switches From Chlorine Gas To On-Site Hypochlorite Generation To Reduce Risks, Improve Safety And Decrease Costs 4/16/2019

    With virtually no local water sources available for use, the City of San Diego relies on water from the Metropolitan Water District, which imports its water from the Colorado River and the California State Water Project. The two massive water projects bring water from other watersheds and regions hundreds of miles to the north and east.

50. Digitization, Water Concerns, And Smart Meters 8/24/2017

    As our society continues to embrace digital technology, it’s fair to say that the world of water utilities will be, a major beneficiary of this revolution.
