Combining blower and process controls to regulate dissolved oxygen levels can make a lot of sense in plants where conventional methods are failing to get the job done.

The Insta-Valve 20-24 provided a targeted shutdown to remove and replace inoperable valves without causing a substantial wastewater facility shutdown.

Explore some of the most common beliefs currently being sold about radar in the environmental market. 

There are many ways to monitor and control ozonation and biologically active filtration systems and operators need to know which one will work best for the intended application.

After years of relying on an inflexible tracking process, A.P. Nonweiler introduced cloud-based remote monitoring technology to increase inventory transparency, save valuable man-hours, and minimize the risk of costly shutdowns.

Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

The Cadiz street Pump Station in Dallas, Texas collects wastewater and pumps it across the Trinity River to the Central Wastewater Treatment Plant .

A Leopold filter system helped save the North Columbus Resource Facility approximately 1,000,000 gallons of water per day that was previously used for backwash purposes.

‘Sonicating’ sludge proves to be a sound method for handling biosolids. By Bryen Woo, aerobic digestion product manager and James Goldhardt, anaerobic digestion group manager, Ovivo

In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

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

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

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.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.
