Wastewater Application Notes

  1. Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution
    9/24/2014

    Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

  2. Pipe Repair On A Budget
    3/7/2014

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  3. Mapping And Identifying The Source Of Water Quality Issues
    6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  4. Bringing Efficiency And New Confidence To BOD5 Analysis

  6. Non-Contact Radar Level Meter Improves Reactor Vessel Measurement
    7/4/2013

    A North Carolina-based specialty chemical manufacturer, a major producer of insect repellent, was looking for a better way to measure the liquid level in its glass-lined agitated reactor. The company uses a number of complex technologies to manufacture sebacates, adipates, isophthalates, catalysts, alkyds, and other natural and renewable chemistries based on castor and citrates.

  7. 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.

  8. 3M™ Liqui-Cel™ Membrane Contactors Are Widely Used In The Soft Drink And Brewing Industries To Control Dissolved Gasses
    7/10/2017

    Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product.

  9. Protecting Pumps From Dead Head Conditions
    4/6/2017

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

  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.
