mini LoP improved performance - Case Study
Meeting very stringent total phosphorous requirements is a challenge for a treatment plant that is receiving wastewater from a dairy process. With a total phosphorous limit less than 100 ppb, a reliable, precise, highly accurate ortho-phosphorous measurement is required to monitor and control the tertiary phosphorous removal process. Small town plants in the upper Midwest commonly encounter this ...

Accurately Measure Hydrocarbon (Oil/Grease) Levels in Produced Water in Under 15 Minutes
Determining total hydrocarbon or oil/grease levels to ensure compliance with regulatory permit requirements for discharging produced water is a worldwide problem facing the oil and gas industry. Ensuring compliance with these regulations and avoiding fines for non-compliant discharges requires more frequent wastewater measurements to determine the total hydrocarbon concentration. The portable ...

Doing it with data - Case Study
In 1994, the Bonnybrook Wastewater Treatment Plant in Calgary, Alta., completed the first phase of an upgrade to biological nutrient removal (BNR) after several years of testing. Bonnybrook was not the first treatment plant to upgrade bioreactors for nutrient removal: Other communities had struggled with the technology. Bonnybrook operators determined that real-time information on final effluent ...

AquaLab Analyzer provides real-time phosphorus measurement in Everglades
When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

Study about the influence of the pH and temperature in a biological wastewater trickling filter with beds of attached biomass to small stones case study
Preliminaries This service is carried out from the agreement reached by Surcis with an engineering company to conduct a study on the approach to analyze the influence of temperature and pH in a municipal wastewater treatment plant provided with a tricking filter process with small stones (as biomass carriers), where there is a very poor nitrification process performance. This biological process ...

TOC Analysis of 3% Hydrogen Peroxide (H2O2) Using the Teledyne Tekmar Lotix TOC Analyzer
Abstract Hydrogen peroxide (H2O2) is used in numerous industries and has a variety of uses including sterilization, wastewater treatment, bleaching and as a propellant. The analysis of hydrogen peroxide for total organic carbon (TOC) content is a quality control (QC) test used to ensure purity. This application note will demonstrate that the Teledyne Tekmar Lotix TOC analyzer is robust enough to ...

Real-time control optimizes extended aeration processes - Case Study
The population of Hillsborough County, Florida has doubled since the Valrico advanced wastewater treatment plant (AWTP) was built in 1990 to treat the sewage of several small communities west of the City of Tampa. When it began operation, the Valrico AWTP capacity was only 4 MGD; small when compared to Tampa’s 96 MGD Howard F. Curren AWTP located not far to the east. But Valrico serves as a ...

Research on a soft measurement model of sewage treatment based on a case-based reasoning approach
In this paper, the measurement of biochemical oxygen demand (BOD) in a wastewater treatment process is analyzed and an intelligent integrated prediction method based on case-based reasoning (CBR) is proposed in order to overcome difficulties. Due to the fact that there are many factors that influence the accuracy of the prediction model, the radial basis function, which is a neural network ...

WWTP installs new affordable ortho-phosphorus analyzer to help contain escalating chemical costs - Case Study
Wisconsin’s Department of Natural Resources recommended a reduction in the state’s phosphorus limit from 1 ppm to 0.05 ppm for inland lakes and streams (0.5 ppm for the Great Lakes) in efforts to improve water quality and reverse eutrophication of state’s lakes and rivers. These new limits when adopted will force many WWTPs to spend more on chemicals and invest in new equipment. ...
