When a storm event shut down both Southern Iowa Rural Water Association pump stations, it caused authorities to scramble to move water to their customers. 

Duperon’s stormwater line of products was designed to address the unique challenges faced in screening stormwater during storms.

Here are tips for solving the most common challenges with SewerGEMS.

Maintenance professionals within Water and Wastewater Treatment facilities are as busy as ever. To keep up with growing demands on their time, they are always looking for ways to improve the reliability and maintenance requirements within their scope of responsibility.

The original plant in Green Lakes, WI, was built in 1983 and did not include grit removal. As a result, grit accumulated throughout the plant process tanks, particularly the aeration basin. This required periodic shutdown of the process tanks and hiring a contractor to vacuum the deposited grit from the tanks. The pending upgrade would include the use of an SBR treatment system as well as an upgrade to sludge dewatering. Plant personnel were concerned about grit settling in the process tanks, as well as grit wearing on the belts and rollers of the new belt filter press that would be used for sludge dewatering. The impact of these problems drove the plant to include grit removal in their upgrade project.

As with many of today’s aging plants reaching 30+ years of service, the outdated technology and in-efficiencies had placed a burden on a West Virginia town and its officials. The system was no longer able to accommodate the community’s growth or meet the effluent requirements on nitrogen and phosphorus.

Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

Publicly Owned Treatment Works (POTWs) are faced with the challenge of processing the effluent wastes of multiple sources: residential, industrial, and environmental. Under laws governing pretreatment, the ultimate responsibility in determining whether or not industrial effluent meets criteria for treatment belongs to the POTW. Once the POTW has the effluent waste within the confines of its treatment facility, it is accountable to the federal, state, and local regulations governing the quality of the wastewater it discharges into lakes and streams or injects underground.

Discover how implementing targeted operational strategies, advanced cleaning protocols, and innovative technological solutions, makes it possible to mitigate the impacts of fouling.

What does it actually cost to build climate resilience into a water treatment plant? The answer depends on the right analytical framework.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.

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.

Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gain an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas. This includes supply planning, maintenance, resource deployment, leakage detection and the overall environment.

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.
