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.

Discover the solution that has helped a global miner experience improved reliability and reduced spending on spare parts and maintenance.

Unlock improved HVAC system performance by implementing modern pump retrofit strategies. Upgrading to high-efficiency pumps and smart controls significantly reduces energy use, lowers TCO, and enhances long-term reliability.

HRSD, the regional wastewater treatment utility in southeast Virginia, had been experiencing high pressures in their Williamsburg area force main network during wet weather events.

Here are some links and guidelines designed to help utilities change their perspective on water as a low-cost resource of virtually unlimited supply. 

Pump oversizing drives hidden costs through energy waste, reduced reliability, and increased wear, making proper sizing and modern controls critical for long-term efficiency and performance.

The pulp mill at Veracel Celulose was commissioned in mid-2005. The HPD® black liquor evaporation system, designed by Veolia Water Technologies and installed by Confab Equipamentos S.A., was considered successful at start up.

It’s just past 10:00 on a Friday night, and the phones start ringing in the pockets of the on-call collection systems operators. It’s an alarm for another pump clog at one of your sewage lift stations — the second one this week.

The AVT EZ Valve provided an efficient solution at the Sellafield Nuclear Site in Europe, saving valuable time and keeping a multi-million-pound project moving on schedule.

Electromagnetic (mag) meters are a desirable metering choice for their incredible accuracy and low to no maintenance required over its lifespan. Operating with no moving parts, the appeal is high – however, the ability to troubleshoot in-field is challenging and time-consuming. Luckily, there’s a major contributing factor in installing an effective mag meter that can set you (and your operations) up for success: grounding.

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

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.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

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

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.

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

Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.
