A wastewater plant in Florida originally had one Parkson Aqua Guard® Self-Cleaning Moving Media Screen in operation for approximately 19 years. When the city expanded, a new headworks plant was built in 2009. At this time, two (2) new screens were purchased from a competitor based on cost through a bid process to contractors.

The key to a successful water treatment or vapor extraction project is to understand the elements that can impact the treatment process, as well dispelling key myths about temporary treatment systems.

Despite their higher upfront cost, ceramic membranes deliver a notable return on investment while providing the same if not better water quality results as polymeric membranes.

Significant innovation had occurred in the 17 years since the TrojanUV4000™ was installed at the Murfreesboro Water Resource Recovery Facility. Advancements associated with system efficacy, simplified maintenance, and energy efficiency had been introduced, all of which correlate to cost savings. Such advancements can all be found in the TrojanUVSigna™ – the UV system that was selected for the upgrade.

For private utility owners and operators, legacy infrastructure isn’t a sunk cost. It’s an opportunity. And with the right retrofit strategy, that aging wastewater treatment facility can become a stable, revenue-generating asset.

As municipalities worldwide look to reuse water for agriculture, industry, and tertiary treatment such as filtration and disinfection prior to discharge or reuse for irrigation or industrial purposes, one inconvenient truth continues to lurk in the pipes: chlorine.

In July 2009, a group of more than 70 leading nutrient removal experts gathered at the Blue Plains Advanced Wastewater Treatment Plant in Washington, DC. The Water Environment Research Foundation (WERF) brought the group together for a workshop to assess the status of our battle to keep excessive nutrient levels from claiming the health of our natural water resources. This gathering of "nutrient warriors" couldn't have come at a better time. Landmark nutrient management activities are already underway.

This article delves into the six most prevalent wastewater treatment issues in industrial treatment plants and explores how jet aeration and jet mixing technology can effectively mitigate them.

A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. By Dale Klussman

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Industrial power plants or co-generation power plants utilize steam for industrial purposes other than power production.

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.
