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.

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?

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.

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.
-
Strategic flow monitoring helps wastewater utilities curb overflows, cut costs, and safeguard public health by turning accurate data into proactive action.
-
When seeking bids for a fair comparison, it’s important to evaluate the total cost of ownership.
-
Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.
-
As technology improves and becomes more accessible, outdated municipal wastewater systems are fast beginning to show their age. Today, water pumps come in a variety of designs that enable uses that previous generations could only have dreamed of.
