WASTEWATER
Resolving Odor Complaints With Targeted Solutions Restore Community Confidence
The South Dearborn Regional Sewer District in Lawrenceburg, Indiana, provides regional wastewater treatment services for three cities and an international distillery. The 6 mgd treatment plant is located in an area of high population growth and is surrounded by many retail operations and other commercial developments. In addition, a heavily traveled state highway runs by the treatment plant.

2nd Generation ATAD Provides Superior Treatment
In a bold move to modernize its wastewater treatment, Bowling Green, Ohio, installed the state’s first second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system—ThermAer—in 2004. The upgrade expanded the plant’s capacity from 6 to 10 MGD and replaced an inefficient, odor-prone coarse-bubble aeration system.

Are You On The Hook For U.S. EPA Effluent Limitations Guidelines?
While wastewater effluent standards mandated by the U.S. EPA and individual states eventually come down to a number, it pays to understand how those standards are established and the challenges of meeting them in real-world applications. Here is a look at the multiple pieces of that puzzle, including their wastewater treatment implications for industrial-scale meat and poultry processing operations.

Why Your Mixer's Motor Rating Matters
Most mixer manufacturers will say that newer-model equipment is generally more energy-efficient than older-model equipment. The question remains, however, just how much more efficient is the new equipment?

How To Predict And Prevent CSOs And SSOs
Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

Water Into Wine
As a young engineer on a farm in California's Central Valley grappling with the challenge of injecting fertilizer into irrigation water, Angelo Mazzei didn't consider how his career would ultimately turn his knowledge of water into a deep involvement in wine. But since he crafted first high-efficiency venturi injectors in the 1970s in his garage to help improve water, fate and business have pulled Angelo Mazzei toward wine from every direction.

Membrane Technologies In Containerized Units Allow For Installation In A Small Footprint
After an international tender process, the Israel Electric Company (IEC) chose Fluence to design, manufacture, and supply containerized ultrapure water production systems for use as makeup water for heat-recovery steam generators (HRSG) and for NOx emission reduction at recently upgraded power plants across Israel. More than 15 units of 20 m3/h production modules, each fitted in two 40-foot shipping containers, were provided to seven power plants. Their compact design allowed for ease of installation, operation, and maintenance while meeting the customer’s demanding engineering standards.

Biogas Measurement From Wastewater To Power Plant
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.

Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water
As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

Optimizing Air Flows To Aeration Basins
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.

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.

LATEST INSIGHTS ON WASTEWATER
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
