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.

Creating Reusable Water From Municipal Sewage
Al Shamal is the capital city of the municipality of Madinat ash Shamal in Qatar. With the majority of the town's population not yet connected to a sewer network, there was an immediate need to provide a wastewater treatment plant to treat wastewater generated from the towns' population and small industries. Ashghal, the Public Works Authority of Qatar and its end user, decided to install a tanker discharge facility with a compact sewage treatment plant to produce effluent suitable for reuse in irrigation.

How The Franklin Miller Dimminutor® Became An Olympic Winner
The Franklin Miller DIMMINUTOR was selected for the state-of-the-art sewage system infrastructure project built to accommodate the Olympic Winter Games in Sochi, Russia. After an intensive construction project, multiple Model DM36XF DIMMINUTOR® open channel comminutors were employed throughout the new sewage system. Each unit has the capability of 29 million gallons of raw sewage per day.

Protecting Pumps From Dead Head Conditions
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.
-
VFD Energy Savings For Pumping Applications
In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.
-
Reduce SBR Maintenance Costs With Jet Aeration
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.
-
Dissolved Oxygen Measurement
One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

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.

Mapping And Identifying The Source Of Water Quality Issues
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.

Sewage Pump Station Level Application
The most common level application in the water and waste water industry is the infamous wet well. With its line-of-sight measurement technology, rugged sensor, narrow laser beam and virtually nonexistent maintenance requirements or on-site calibration, ABB’s LLT100 laser level transmitter answers most concerns related to wet well level measurements and makes it easy to calculate what could amount to a substantial return on investment.

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.

Scrubber Application
This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.
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.
