WASTEWATER ANALYSIS WHITE PAPERS & CASE STUDIES

Microbiological Monitoring Of Paints Using 2^nd Generation ATP

A paint manufacturer produces a wide range of paint products for industrial, commercial, and residential applications. The products are manufactured in large batches of up to 10 tons. Before each batch is packaged and shipped, a number of tests are performed to ensure that the product meets strict quality control requirements. 

• Using ATP To Reduce Risks From Legionella In Cooling Towers
• Rapid Microbial Assessment Following A Case Of Legionellosis

• Troubleshooting A Sudden Fecal Coliform Non-Compliance Event

  A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.

• FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?

  Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

• Are You Experiencing Deviation Alarms In Your High Pressure Process Vessels?

  In this white paper, learn how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.

• Starch Mill Anaerobic & Aerobic WWTP Monitoring Program

  Over the course of a 1.5-month field experiment at a Canadian starch mill biological wastewater treatment process, LuminUltra Technologies demonstrated the benefits of using 2nd Generation ATP® monitoring technology. ATP (Adenosine Triphosphate) monitoring technology is an accurate biomass measurement that can rapidly monitor all types of biological wastewater treatment processes, aerobic and anaerobic alike.

• Bulk Emergency Chlorine Vapor Scrubber System Restored For Oklahoma City

  As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.

• Biological Water Treatment: Only The Best Instruments Are Good Enough

  Vallviks Bruk AB, located about 200 km (125 miles) north of Stockholm, produces softwood kraft pulp and chemical pulp for export. Some years ago, increased environmental requirements led to a major investment in a biological treatment plant. Read the full case study to learn why ABB instrumentation was an obvious choice when the Swedish pulp producer Vallviks Bruk AB built a new plant for biological water treatment.

• Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China

  The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

• Carbon Dioxide For pH Control Of Landfill Leachate

  A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

• Improving Sludge Dewatering Process Control
  With RTC-SD

  A WWTP sought solutions to improve process control, as high centrate solids caused plant inefficiencies such as high wasting rates, inefficient capacity and loading, and stress on centrifuges. Read the full case study to learn how the RTC-SD solution controlled polymer dosing in real time, allowing the WWTP to improve solids capture and increase throughput.

• VTScada And OpWorks Provide Advanced Wastewater Reporting And Analysis

  Rapid City is the second-largest city in South Dakota, serving over 72,000 residents. Their Water Reclamation Department treats nearly 3.5 billion gallons of wastewater annually.

RTC‐ST Reduces Polymer And Increases Biogas Production

Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.

The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)

A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

Continuous Analyzer Integrated Data Validation

Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.
