Lagoon-Based Extended Aeration System Meets Effluent Requirement For Year-Round Ammonia Reduction In Stoddard County, MO, the sewer district required a new wastewater treatment facility to service residential growth in the community. By Environmental Dynamics, Inc.

How To Avoid The Biggest Wastewater Aeration Mistake

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.

Riviera Utilities WWTP Upgrades To State-Of-The-Art Aerobic Granular Sludge Technology

Instead of taking the traditional approach of adding an additional oxidation ditch to increase treatment capacity, Riviera Utilities had the desire to “future-proof” the plant and prepare to meet more stringent effluent requirements.

Efficient Blower Selection At WWTPs

In general, the term blower is a machine used for moving gas with a moderate increase of pressure, but it is easier to answer the question if we compare the fan, blower, and compressor. An air compressor has a high pressure-to-volume ratio, whereas an air blower has a low pressure-to-volume ratio.

EPA Researchers Develop Tool To Assess Onsite Non-Potable Water Reuse For Buildings Across The U.S.

Increasing pressure on water resources has led to greater water scarcity and a growing demand for enough clean water. Many communities across the country have initiated, or are in the process of developing, centralized systems for planned water reuse. Water reuse is the concept of intentionally recycling, treating, and reusing alternative water sources. Federal government agencies and the water user community are coordinating their efforts to advance the adoption of water reuse and ensure the security, sustainability, and resilience of water resources. The National Water Reuse Action Plan (WRAP) describes these collaborative actions.

How To Boost Industrial Plant Capacity By Retrofitting Aeration Tanks

As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.

The Fine Points Of Headworks Screening (Part 2 Of 3)

Protecting wastewater treatment facilities requires operators to think strategically about their unique challenges and identify the best solution for their specific requirements. Specifying the appropriate headworks system for the plant’s needs is arguably one of the most important design decisions a public works engineer will make.

How Industrial Facilities Can Achieve Compliance And Prevent Downstream Contamination Using Advanced Oxidation Processes

Read about how advanced oxidation processes can offer exceptional benefits in preventing contaminants from leaching into groundwater and surface water. 

Aeration And Mixing Bring Hussain Sagar Lake's Ecosystem Back To Life

Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community.

Process Optimization For Flow Measurement

The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water. 

Simplify And Optimize Your Process With Level And Pump Control

Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

Why Measuring Hydrogen Sulfide In Wastewater Matters

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.

Reducing And Reusing Water In Steel Manufacturing

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.

FLEX-TEND® Flexible Expansion Joints, Features And Specifications

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

MEGA-STOP Bell Protection System Aids In Pipe Joint Assembly

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

Nitrogen-Reduction Treatment Systems For Long-Term Operations

The need for of 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.

Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

Sewage Lift Station Pumping System

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Dissolved Oxygen Measurement In Wastewater Treatment

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