Contingency planning for sewer system failures is often overlooked. Learn why a successful contingency plan can reduce costs, save reputations, and protect public health.

Hollywood, Florida’s 55.5 MGD Southern Regional Wastewater Treatment Plant (SRWWTP) treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 MGD of additional reuse on an annual basis.

The benefit from the simple automation capability of the Huber Technology Q-Press^® began for Contentnea MSD WWTP shortly after installation. Staff was able to focus elsewhere as little attention was required for the system’s operation. The end-product dryness levels vastly improved which radically reduced their haul off costs. Read more.

The air foil bearing, allowing operation without the need for lubrication and maintenance, provides minimum life-cycle costs for the entire unit. Filtration is the only preventive maintenance which is necessary. The production costs of the complete assembly are very low due to the less expensive bearing technology in comparison to turbo compressors made with magnetic bearing this is a significant benefit in addition to reduced cost of eliminating necessary ancillary components such as bearing controllers, additional electrical filters and uninteruptable power sources.

The sky is blue, grass is green, and, someday, your pumps are going to clog. It’s just another fact of life — or is it? 

The West Central Conservancy District (WCCD), located in Hendricks County, IN, was formed to resolve sewer issues that the service area was experiencing with the local utilities company in the mid- ’80s.

Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

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.

Wastewater constituents are getting more plentiful and complex, requiring more advanced tools to maintain regulatory compliance.

Conventional activated sludge wastewater treatment plants (WWTP) operate with solids (mixed liquor suspended solids ­– MLSS) concentrations ranging from approximately 1500 to 5000 mg/L. In membrane bioreactors (MBRs), typical MLSS concentrations are even higher (10,000 to 12,000 mg/L). 

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.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

A non-toxic, advanced oxidation (AOP) formula of minerals chelated with oxygen and stabilized in an aqueous water solution. It is a viable option in industries and applications requiring a solution to challenging situations where high level effective sanitization and oxidation is required. Read more to learn how the Genclean advanced oxidation treatment solutions can be used in different applications.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

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.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.
