Wastewater Application Notes

1. Flexible Expansion Joints Provide Protection For Pipelines Subject To Subtle Or Sudden Movement 12/7/2020

   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.

2. Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing 9/18/2017

   With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

3. Dissolved Oxygen Measurement In Wastewater Treatment 11/11/2013

   A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

4. VFD Energy Savings For Pumping Applications 4/6/2017

   In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

5. Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process 12/1/2019

   Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

6. Remote Monitoring And Maintenance Through Digitalization 3/17/2020

   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.

7. Bringing Efficiency And New Confidence To BOD₅ Analysis 2/4/2013

   Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

8. AquaSBR Sequencing Batch Reactor: Food And Beverage Industry 12/6/2023

   This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

9. Alcoholic Beverage Fusel Alcohol Testing With Static Headspace 9/2/2014

   A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

10. Reducing Total Phosphorus In Water Resource Recovery Facilities 9/10/2014

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.
