Wastewater Treatment Case Studies and White Papers

  1. WEDECO UV Disinfection Produces Highly Purified Water In Silicon Valley

    With diminished rainfall, a depleted aquifer basin, near-empty recharge ponds, and an earthquake-vulnerable aqueduct system, the Santa Clara Valley Water District (SCVWD) in San Jose, CA, required additional water supplies to maintain regional economic vitality for its growing community.

  2. Desalination Serves Coastal Argentine City

    When a series of water crises in 2014 disrupted conventional utility services in the coastal Argentine city of Caleta Olivia, the city needed a way to ensure an uninterrupted water supply.

  3. Lift Station Reduces Clogging, Lowers Operating Expenses With Self-Cleaning Pumps

    Aging pumps at Jackson Energy Authority’s Rolling Acres Lift Station (Jackson, Tenn.) resulted in frequent clogging and outages that required costly maintenance and repair.

  4. A Midwest Wastewater Plant Identified VigorOx WWT II As Disinfection Solution To Meet New Regulatory Requirements

    The City of Hannibal, Missouri, sought a cost effective disinfection technology to meet upcoming National Pollutant Discharge Elimination System (NPDES) permit. Read the full case brief to learn how the full-scale test confirmed that VigorOx WWT II is a cost effective solution for this plant to achieve the disinfection goals.

  5. Headworks' MS Series Bar Screen Is The Equipment Of Choice For The Puerto Rican Sewer Authority's Caguas Wastewater Treatment Plant

    Even though it is a small island, Puerto Rico has historically had big issues with sewage treatment. Due to its tropical location in the Caribbean, heavy storms can create unusually large peak flows at the treatment plants.

  6. Changxing Power Plant Debuts The World’s First Forward Osmosis-Based Zero Liquid Discharge Application

    Desalination Technology Transforms 650 m3/day of Abused Industrial Wastewater

  7. Three Wastewater Treatment Issues That Can Be Improved With High-Purity Oxygen

    Wastewater facilities in various industries face challenges in day to day operations. Some of these treatment issues can be addressed by incorporating high-purity oxygen into the wastewater treatment process. Below are three common wastewater treatment issues and how oxygen may help.

  8. Measuring Tube Construction Affects The Long-Term Stability Of Magnetic Flow Meters

    Electromagnetic flowmeters, also known as mag meters, are popular and proven devices for flow measurement of electrically conductive process fluids and for volumetric filling machine applications. Of prime importance to a mag meter’s accuracy and long term performance is the condition of the metering section of the flow sensor. By Dipl.-Ing. F. Hofmann and Dipl.-Ing. B. Schumacher, KROHNE Messtechnik GmbH Co KG Duisburg, Germany

  9. New Developments In Thermal Dispersion Mass Flow Meters

    This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments

  10. Waste Lagoon Rehabilitation A New Look At An Old Problem

    Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons. By Jim Dartez, RELIANT Water Technologies
