Wastewater Case Studies and Whitepapers

41. Advanced Grit Removal Resolves Plant's Combined Sewer Challenges 11/22/2016

    A Pennsylvania treatment plant upgraded its headworks to an innovative grit removal system that handles combined sewer storm surges, removes fine grit particles, and lessens maintenance on operations staff.

42. Using Master Controls To Enhance Aeration And Reduce Power Use 8/6/2019

    Precision management of dissolved oxygen (DO) allows wastewater treatment plant operators to maintain optimal biological conditions in their activated sludge basins. However, older blowers and a lack of advanced aeration oversight can sabotage that effort while substantially wasting money.

43. Maximum Security With The Space-saving SPIRALIFT® SLV 11/9/2020

    Due to the waste from the Northeast Correctional Facility, Alliance Water Resources, the wastewater treatment plant in Bowling Green, Missouri, was constantly having problems. The prison, which produces 300,000 gallons of water per day, was creating a deluge of problems for the pump station, including clogged and plugged pumps, excessive power draw and the need for continuous service and ultimate pump replacement. The inmates were flushing paper, jumpsuits, and all manner of debris – pretty much anything they could flush. It was costing the plant a lot of downtime and tons of money. Once the pumps started needing total replacements on a very frequent basis, costing the plant more than $30,000 each year, they knew they needed a solution.

44. How To Balance Dissolved Oxygen Levels For Maximum Efficiency 5/26/2020

    While dissolved oxygen (DO) levels are critical considerations in aerobic wastewater treatment processes, not every application maintains a consistent level of demand. How industrial wastewater treatment plants (WWTPs) track and fulfill those needs make a big difference in the optimum performance and cost-efficiency of their operations.

45. Valve Upgrades Reduce The Number Of Corrective Work Orders By 99% 12/4/2025

    A water treatment plant was using conventional electric actuators on valves across the facility, including the modulating Filter Effluent applications. A history of actuator problems prompted plant personnel to consider replacements.

46. How Ozone Treatment Tackles Pharmaceutical Residues In Wastewater 12/17/2024

    In this blog, we explore how ozone technology helps reduce pharmaceutical residues in wastewater, ensuring safer water for both the environment and communities.

47. How Flow Technology Can Ease The Inflow And Infiltration Headache 12/20/2024

    This article will explain why rain-dependent inflow and infiltration (RDI&I) measurement often fails and how to produce the level of data quality that can detect, understand, and manage it.

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

    The Prosonic S FMU90 and FDU92 ultrasonic system measures the difference in water level between two sides of a filtration system. By Endress+Hauser, Inc.

49. Bioloop Retrofit Reduces Energy Consumption By 43 Percent 3/31/2015

    When a broken shaft caused a malfunction in one of the brush aerators at the village of Liberty, NY, WWTP, the village worked with its engineers to develop a plan for repair and upgrade.

50. Why Municipalities Can't Afford To Do What They've Always Done, Choose Closed Vessel UV 1/9/2017

    Ultraviolet disinfection is now a standard feature in most wastewater treatment systems. UV has also been embraced by the drinking water community as an effective barrier against chlorine tolerant organisms such as Cryptosporidium and Giardia. The technology is widely favored in wastewater treatment due to its non-chemical nature, the fact that no subsequent dechlorination process is required and its ability to be unselective in disinfection performance.
