A new wastewater treatment plant with an average daily flow (ADF) of 0.25 MGD was constructed in 2010 for the Heard County Water Authority to replace its existing plant.

The AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) process is a biological wastewater treatment process that utilizes specialized plastic carriers to create a surface on which a biofilm can attach.

When it comes to pH measurement in water and wastewater treatment, there are two focal points for the word ‘standard’ — one is a compliance-related state or federal water quality specification; the other is a specific fluid used as a calibration reference point to ensure pH instrumentation accuracy. Here is why both are important and how they affect the best pH measurement outcomes in both areas.

In an era of increased scrutiny for delivering efficient and sustainable industrial practices, the maxim “you can’t manage what you don’t measure” is well known to anyone, particularly those whose daily role revolves around monitoring and improving water quality.

Located at 10,400 feet in the Uintah Mountains of Utah, Camp Steiner is the highest Boy Scout camp in the United States.

A phase-activated sludge system (PASS) reduces energy consumption by combining the aerobic and anoxic tanks and alternating diffusers between the on and off position based on a preprogrammed schedule.

Diverse wastewater flows from mixed-use projects strain conventional systems. Learn how advanced biological treatment stabilizes unpredictable loads, ensures compliance, and delivers high-quality water suitable for reuse.

If the wastewater treatment plant serving Reading, PA, and 11 surrounding municipalities has a mission statement for its day-to-day operations, it couldn’t be simpler or more critical: “95°F.”

Jet aeration retrofits modernize aging wastewater tanks with minimal downtime, integrating easily into existing basins while delivering long-term reliability, higher oxygen transfer efficiency, and significantly lower lifecycle costs.

The use of chlorine to treat and disinfect drinking water and wastewater has been in practice for decades, with the earliest recorded attempt dating all the way back to 1893. Since then, it has come a long way.

This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

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

The need for 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.

Read an overview and maintenance tips for chain and scraper systems. 

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

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

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.
