WASTEWATER ANALYSIS WHITE PAPERS & CASE STUDIES

Rumors, Half-Truths, And Truths About Temperature And pH

A few months ago I received a call from an angry user who was using one of our differential probes and a controller. Embedded in the probe is a thermistor that measures temperature.

  • Color, Turbidity And Philosophy
    Color, Turbidity And Philosophy

    When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.

  • Case Study Of Swan Turbiwell Quarterly Calibrated Unit Versus Quarterly Verified Unit
    Case Study Of Swan Turbiwell Quarterly Calibrated Unit Versus Quarterly Verified Unit

    This paper presents the field data collected over a twelve month period at a municipal surface water treatment plant employing traditional clarification and filtration.  The final effluent turbidity was monitored by the third party compliance turbidimeter, a Swan Turbiwell (Protocol Turbiwell) was calibrated quarterly just as the compliance turbidimeter, and a second Swan Turbiwell (Non-protocol Turbiwell) that was not calibrated.

  • Smart Wireless Technology Solves Environmental Monitoring Challenge
    Smart Wireless Technology Solves Environmental Monitoring Challenge

    Faced with the challenge of meeting environmental monitoring legislation, Korsnäs Gävle needed a way to monitor water from their heat exchangers for contamination before discharging it to the sea. Additionally, the board and paper manufacturer required new sensors for continuous monitoring of pH, dissolved oxygen, and water temperatures from effluent emissions in their basins and ponds. In this case study, learn how Korsnäs Gävle implemented a wireless sensor network to quickly  achieve compliance and meet its monitoring needs.

  • How To Control Activated Sludge With Online Sensors
    How To Control Activated Sludge With Online Sensors

    The goal for domestic wastewater treatment in the 21st century should be to have a minimal carbon footprint and to be 100% self-sustainable with regards to energy, carbon, and nutrients – while achieving a discharge or reuse quality that preserves the quality of receiving waters (Water Environment Research Foundation (WERF), 2009). Sustainability with respect to energy requires both conservation and production. By Dr. Robert Smith, Ph.D., P.E., BCEE, YSI, a Xylem brand

  • Low WWTP Operating Costs And High Water Quality -- It's Possible
    Low WWTP Operating Costs And High Water Quality -- It's Possible

    Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. By Patrick Higgins

  • Case Study: Continuous Online Monitoring Of Nitrate And Sludge Using UV/VIS Spectroscopic Sensor Monitoring nitrates, total suspended solids and sludge volume concentrations ensures effluent quality, which is critical for meeting water quality standards for various regulatory agencies. By Endress+Hauser, Inc.
  • Case Study: YSI Multiparameter Instruments Assist In Storm Water And Combined Sewer Overflow Monitoring The city of Indianapolis, Indiana has been monitoring surface water quality of the White River and its tributaries since 1991. Each year the Indianapolis Office of Environmental Services (OES) collects nearly 6,000 samples from 27 locations. Two specialized programs, Continuous Dissolved Oxygen and Critical DO, are designed to collect data during periods when the potential exists for dissolved oxygen problems
