Flow-based DO control and advanced blowers help stabilize aeration, reduce energy consumption, and improve treatment performance, turning a major wastewater cost center into an efficiency opportunity.

Quechan Casino Resort, a gaming facility located on Native American owned land in Winterhaven, California, began its wastewater treatment operations in January 2009.

From ragging and grit to odors and cost constraints, wastewater operators face persistent challenges. Proven headworks technologies and preventative maintenance help utilities improve performance, reduce downtime, and control costs.

Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading to tertiary treatment and the removal of BOD, TSS and Total Nitrogen.

As the Coronavirus pandemic is upending life across the country, it is also putting a major strain on the nation’s wastewater systems.

Thermal mass flow meters do a good job of measuring gas flows in water treatment and wastewater treatment applications. Measuring digester gases, which can contain moisture ranging from vapor to droplets, however, makes the job a bit tougher for all gas flow measurement technologies. Identifying the right solutions to deliver accurate, repeatable and reliable readings without having to reengineer the piping system becomes much easier and more economical by following these helpful guidelines.

When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

Each season brings expected changes to the weather. But with climate change and the warming of the atmosphere, weather patterns are becoming less predictable with more heat waves, and increased severity of super- and local- storms. 

The ROVVER X SAT II lateral launch crawler allows Pittsburgh Water & Sewer Authority (PWSA) to traverse steep pipe inclines with ease, which previously posed challenges for the team.

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

Precise pH control is critical in biomanufacturing processes to ensure product quality, consistency, and safety. This application note explores the challenges of pH management across bioprocessing stages and introduces Pulsafeeder’s NextStep pump as a reliable solution for accurate chemical dosing and process stability.

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.
