WASTEWATER

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

  • Decentralized Wastewater Treatment In A Housing Development

    Young’s Cove is a masterfully planned exceptional waterfront community situated in pristine Prince Edward County, on the shores of Lake Ontario. It has panoramic views, a children’s waterpark, miles of pathways, green spaces. It covers 7,000 feet of shoreline and fronts protected wetlands and preserves hundreds of acres of forest with birds and wildlife everywhere.

  • Municipality Looks To Expand Plant Capacity While Reusing Existing Systems

    Sharjah Municipality of the Untied Arab Emirates (U.A.E.) was requiring to treat more and more flow despite having very little space for new treatment systems. They were looking at wanting to expand their plants No. 4 & No. 5 plants to meet new total nitrogen limits and try to do so by having to reuse the existing systems. This type of upgrade would save on cost as well as space at the plant.

  • Answering Aeration's Big Dilemma — Repair Or Replace?

    In wastewater treatment plants (WWTPs), repair vs. replace considerations are an ongoing dilemma. How much money is it sensible to spend repairing an older piece of equipment vs. upgrading to the best overall replacement option for current operating conditions? Even if the underlying hope is for a quick and easy repair, the answers are not always cut-and-dried. Before making the default decision to repair, evaluate key points that can pay dividends both immediately and over the long run.  

  • McCrometer's Startup Service: An Overview

    Sometimes, a meter installation isn’t as straightforward as we’d like it to be. Many flow monitoring projects can start out simple and evolve to be very complex, especially when the meter is meant to solve a challenging measurement issue. To prevent potentially time-consuming and frustrating delays and issues, McCrometer offers a startup service. So, what does this service include, and should you book this service for your next meter project?

  • Orbal® System for Biological Nutrient Removal

    Discover how a fast-growing community's new WWTP meets new tighter limits on ammonia, phosphorus, and nitrogen for future growth.

  • Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem

    The Howard County, Maryland, Bureau of Utilities completed a project at the Little Patuxent Water Reclamation Plant to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay.

  • Reassessing The Value Of Water Reuse In Process Efficiency

    In many industrial applications, water is not part of the final product but an important process facilitator — for cooling, cleaning, etc. Like energy, it can quickly become a major expense and, therefore, an important target for cost control. As potable water supplies tighten or become increasingly expensive, reuse is becoming a more attractive alternative. Here is some of the information needed to evaluate the opportunities it offers.

  • Changxing Power Plant Debuts The World's First Forward Osmosis-Based Zero Liquid Discharge Application

    Desalination Technology Transforms 650 m3/day of Abused Industrial Wastewater

  • Testing Better Paths To Contaminant Control

    As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. 

  • New Money Flowing Into U.S. Water And Wastewater Infrastructure

    Highways and bridges are the most noticeable examples of the United States’ crumbling infrastructure, but there are other, less visible infrastructure systems that are equally in need of fixes and funding -- including water and wastewater treatment.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

With more than 60 years’ experience supplying dewatering pumps to some of the most demanding sites around the world, Xylem has designed the Flygt 2600 series to stand up to the toughest conditions.

Aerzen’s AERprocess Dissolved Oxygen Control is an integrated solution for controlling the dissolved oxygen (DO) concentration in the activated sludge treatment process and the blowers used to generate the process air flow requirement.

Each aerator shall be capable of producing 3.0 lbs. of oxygen per nameplate horsepower per hour under normal conditions during aeration. Each 15 HP aerator shall be capable of pumping and mixing approximately 4,032,000 gallons per day under normal conditions and continuous operation

With increasingly stringent regulations and adoption of membrane filtration, the pressure is on for all stages of pretreatment — chemical feed, flocculation, sedimentation, and filtration — to act in concert. In response, Meurer Research, Inc. has developed MRI Flocculation Systems™ — integrating turbine, horizontal, and hydraulic flocculators into multi-stage systems with a self-cleaning hydraulic final stage, maximizing versatility and performance.

Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.

For the toughest debris conditions, the Duperon® Self-Cleaning Trashrack easily handles heavy vegetation, large refuse, logs and other harsh, rugged debris. The front-clean, rear-return technology is able to stand idle for long periods, yet still reliably start whenever a storm or rain event occurs. Independently operating chain strands offer built-in redundancy and continuous operation when it’s most critical.
