Smarter measurement supports safer, more efficient and more sustainable operations, improving uptime and extending servicelife, whatever the industry sector.

Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.

Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

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.

Here are several important considerations for getting maximum value from produced-water RO treatments at minimal total lifecycle costs.

Toward the end of the 1980s, Professor Kazuo Yamamoto from Tokyo University gave a lecture to a skeptical crowd. His topic? Immersed hollow fiber membrane bioreactors. Since the day that first audience listened to the possibilities of MBRs, much work has been done to make membrane bioreactors a common step in the wastewater treatment process.  

This bulletin describes the restrained length calculations for dead ends, valves, reducers, and sleeves with a discussion of several situations where economics and other factors may favor an alternate restraint method. 

To comply with new EPA rules and handle additional flow, the City of St. Charles Missouri WWTP required a capacity increase, and the landlocked plant needed a solution that would fit within its existing footprint. Brush aerators and boat clarifiers were replaced with 12 VLR-mounted disc aerators to fulfill the oxygen requirement while allowing for the treatment of higher organic loading. The solution provided increased nutrient-removal capacity and improved efficiency without increasing tank volume.

Septage disposal requirements have come a long way since the days when haulers could simply discharge their loads into an open pit at a sewage treatment plant or off-load them into a field or lagoon. This process was often neither regulated nor monitored. Haulers submitted their own estimates of what and how much they dumped for billing purposes. This practice created a very real threat of ground water, lake and stream contamination.

In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large consumer of both energy and operational costs. The Aire-O₂ Triton aerator/mixer is a process aeration technology that addresses both of these aspects and is environmentally friendly, which is a winning formula to help achieve long term sustainability.

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

The 2000PV is a restraint for PVC pipe and the standardized mechanical joint. This product is the result of years of testing and evaluation and its performance has been proven by thousands of hours of proof tests, as well as third-party evaluations. This report describes the 2000PV through the 12" size.

Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.

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

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 Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.
