WOL_south-dearborn_385x250 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.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • The Selection & Use Of Sludge Muncher Grinders & Wastewater Munchers

    Sludge grinders are inline processors that play an important role in the successful operation of wastewater treatment plants by reducing oversized solids that can causing jamming and damage to pumps and process equipment. Franklin Miller grinders are known for their heavy-duty capabilities and innovative designs with models available for a variety of application requirements.

  • Retrofitting Water Systems With The Best Meters For The Job

    Although not every water, wastewater, or industrial design engineer or operations manager is familiar with the advantages of the V-Cone differential-pressure (DP) meter design, they are certainly familiar with the problems it can solve. Here is a step-by-step description of how V-Cone meters with + 0.5 percent accuracy offer better alternatives in applications currently being failed by other metering technologies.

  • ATAD Provides Increased Capacity With No Odors

    Faced with persistent odor complaints and limited space, Douglas County Sewer District #1 in East Wenatchee, Washington, turned to the ThermAer second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system to modernize its biosolids treatment.

  • Igudan's Water Reuse System Saves Millions In Irrigation Costs

    Learn how a WWTP overcame the challenge of encountering unidentified wastewater events from unknown sources that impact its processes.

  • Microfiltration Membranes Lead The Way In Water Filtration

    For water treatment professionals prioritizing precision and efficiency, hollow-fiber microfiltration membranes are revolutionizing the way industries and municipalities treat water.

  • Decoding Ozone Disinfection Revisited

    Late last year we published an extremely popular article on understanding the ozone disinfection process. Based on the response, we’ve updated this year’s article with a bit more information to illustrate how powerful these simple tools can be to operations staff.

  • Abbottstown Retrofitted A Flow-Through System With An AquaSBR® System To Meet Stringent Effluent Requirements

    The Abbottstown-Paradise Joint Sewer Authority was incorporated in 1973 and utilized a continuous flow activated sludge system with an average daily design flow of 0.21 MGD. At that time the plant was only required to reduce total suspended solids (TSS) and effuent ammonia to required levels to serve the area population of about 2000. Due to urban growth and increased storm flow runoffs, the plant was in need of an expansion and upgrade by the late 1990s. 

  • Phosphorous Solutions For Wastewater Treatment

    This paper presents a comprehensive overview of technologies for phosphorus removal and recovery, including chemical and biological processes, ballasted clarification, filtration, and nutrient recovery.

  • Crusher Takes Its Lumps, Minimizes Elbow Grease

    CCP, Inc. in West Paterson, N.J. makes over 1,000 product formulations under private labels for the cosmetics industry, using materials such as persulfates, alkali silicates, phosphates, sodium chloride, and magnesium chloride.

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

Remove more, finer grit to protect downstream treatment equipment, increase plant efficiency and cut maintenance and repair costs. The HeadCell® is a stacked tray grit, sand and solids separator that captures and retains 95% of all wastewater grit 75 micron (µm) and larger. With a small footprint, no electrical requirements and no moving parts the HeadCell® delivers exceptional and economical solids removal for small, medium or large wastewater treatment plants.

Tekmar’s newest addition to the TOC analyzer product line, the Torch, utilizes a patent Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion.

Tube settlers and parallel plates increase the settling capacity of circular clarifiers and/or rectangular sedimentation basins by reducing the vertical distance a floc particle must settle before agglomerating to form larger particles.

DO2E Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices that are unique in several ways. DO2E’s patented products are designed to pull water from significant depths for aeration and mixing. By operating with low-pressure (<1.85 P.S.I.) high-volume airflow, these devices maximize energy efficiency. Our patented products are scalable and multi voltage.

The OPTIFLUX 4050 is an electromagnetic flowmeter (EMF) for chemical applications in non-hazardous areas. It provides cost-effective measurements with good accuracy and standard diagnostics and communication options. The extra isolation of the electronic device and housing makes this EMF particularly suitable for use in areas with extreme humidity and chances of flooding.
