Officials at the Jefferson Parish Sewerage Department approached the team at Digital Engineering to find a long-term solution for the odor and corrosion issues throughout the East Bank Wastewater Treatment Plant. 

A Chicago stormwater diversion tunnel designed to correct a chronic flooding problem that has plagued the city’s Albany Park neighborhood over the past decade has been recognized for its effectiveness and ingenuity.

In 2017, a municipal water treatment plant was commissioning a new elevated tank. The tank had been cleaned, flushed and disinfected, but initial test results indicated unacceptable water quality. After a second cleaning, the tank was refilled and water samples were sent to the lab for follow-up testing.

Pneumatic conveying applications are critical to many facilities – when you can’t move material you can’t make or sell your product. Because of a historical lack of availability of specialized rental blowers and compressors for pneumatic conveying, plants often ether accepted the production outage or rented a more readily available 2 stage oil-free rotary screw compressor designed for 90-150 PSIG plant air service that is very inefficient at the reduced pressures needed for pneumatic conveying.

A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation.

It’s common for wastewater treatment plant operators and design engineers to get comfortable with one type of blower for aeration. However, multiple blower technologies are available to consider when designing a new system. Understanding the difference between them, as well as the pros and cons of each based on the specific application, is critical to the decision-making process.

By providing valuable data and insights, pilot tests enable facilities to make informed decisions, optimize their operations, and mitigate risks associated with new technologies.

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.

Explore why he Hach Ultra Mag is a fan favorite in numerous industries such as municipal water and wastewater, amongst others.

Read about a utility that sought alternate disinfection process options to replace equipment that had reached the end of life. 

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.

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

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.

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.

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

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.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.
