Eliminating Sludge Islands In Your Wastewater Lagoon

Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons.

The Tip Of The Fatberg: How FOG Affects Our Sewer System

Fats, oils, and grease, commonly referred to as FOG, are one of the most prevalent contributors to sanitary sewer blockages and overflows. In this blog, we will explore the impact of FOG and what can be done to control it.

Case Study: Incorporating Innovative Stormwater Management Technologies Into A Sustainable Integrated Use System AquaShield, Inc. showcased a sustainable approach to water management using various stormwater treatment and water conservation technologies at their new corporate headquarters in Chattanooga, TN, with Congressman Zach Wamp as the keynote speaker for the event. Working with a blank canvas for a new building and site design, AquaShield decided to put into practice what many just talk about when it comes to implementing environmentally friendly practices.

Hydra-Stop Solutions Isolate Damaged Valve During Water Main Replacement

The Village of Covington, Ohio had an ambitious 90-day project to replace the water main, taps, sewer main, laterals, and storm sewer through the center of town. Unfortunately, on day one, an unknown water service line was snagged and the top half of an 8” valve blew off, causing water to shoot 10”–12” out of the street.

Nanobubble Ozone Technology – Advancing Mass Transfer Through Physics

Nanobubble physics enable higher ozone stability and mass transfer efficiency in water. Discover how the negative surface charge of these microstructures improves localized oxidation and penetration into difficult matrices.

Membrane Aerated Biofilm Reactor Technology Validated For Title 22 Compliance

Title 22 of California’s Water Recycling Criteria is among the strictest water treatment standards for water recycling and reuse in the United States. Fluence’s MABR demonstration plant was installed at the Codiga Resource Recovery Center (CR2C) in Stanford, California, in January 2018 for the purpose of third-party evaluation. The testing parameters included criteria to evaluate reliable enhanced nutrient removal in the form of Total Nitrogen, which is increasingly important across the United States and difficult and costly to achieve through conventional wastewater treatment.

Chemical Feeders: A Guide To Successful Start-Up And Operation

Disinfection is essential to municipal water treatment — for both producing a quality product and meeting environmental discharge limits — but the dosing process can be expensive and tedious if not administered efficiently. By carefully evaluating key factors in equipment selection and operation, water and wastewater management professionals can ensure their systems are running as efficiently and effectively as possible.

Meeting Strict TN Limits: ANITA™ Mox

The City of Durham, NC, completed a comprehensive wastewater master plan that evaluated different treatment techniques for meeting strict total nitrogen (TN) limits at the South Durham Water Reclamation Facility (SDWRF).
