Factoring Temperature Into Water Chemistry Reading Accuracy
Factoring Temperature Into Water Chemistry Reading Accuracy

In water testing, readings that we believe to be reliable indicators are not always what they seem. Water that exhibits certain chemical or electrical characteristics at laboratory temperatures can provide entirely different readings in the field. Here is a quick review of what to look for in common water tests and why to consider automatic temperature compensation in the instruments used to collect them.

  • Organics Aren’t Invisible: A Guide for Simple Online Monitoring
    Organics Aren’t Invisible: A Guide for Simple Online Monitoring

    Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on turbidity for monitoring and process control.

    Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

  • Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

  • Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results
    Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

    When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

    Sounding The Alarm On Silent Noncompliance

    Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.

    Fine Tune Your Lab Testing Accuracy With Compliant Proficiency Testing (PT)

    Proficiency Testing (PT) is the name used by the International Standards Organization for a procedure also known as “inter-laboratory study” or “external quality assessment” or “ring test”. Proficiency testing, in simple terms, comprises a sample sent to a group of laboratories for measurement. The labs know what might be in the sample, but they don’t know exactly what is there or the concentration. Their results are compared with the known or true value and the lab is assigned a “Z” score to show how closely their result came to the target.
