Wastewater Analysis White Papers & Case Studies

  1. Five Years Of Post-Aeration At A Wastewater Treatment Plant
    5/28/2015

    To protect the environment, wastewater treatment facilities across the country are required to deliver dissolved oxygen (DO) into the treated effluent, with most DO permits ranging from 2 to 10 mg/L.

  2. Rumors, Half-Truths, And Truths About Temperature And pH
    4/6/2015

    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.

  3. How Automated Real-Time Controls Can Provide More Consistency In Wastewater Treatment Operations
    3/19/2015

    Within a wastewater treatment plant (WWTP), operators typically face an extremely wide range of different variabilities.

  4. Coal Yard Runoff Compliance Using Actiflo® Technology
    3/6/2015

    Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

  5. Measure And Control Cyanide With The CNSolution 9310
    3/2/2015

    The CNSolution 9310 analyzer is used in precious metal processing to measure and control cyanide used in the hydrometallurgical leaching of gold and silver from the ore.

  6. Color, Turbidity And Philosophy
    1/28/2015

    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.

  7. Pilot Testing Potassium Sulfate Crystallization
    1/13/2015

    ICP’s Ochoa Mine Project is projected to produce approximately 714,000 tons per year of SOP (K2SO4) from polyhalite ore for greater than fifty years as concluded in a feasibility study.

  8. Calculated pH By Differential Conductivity Measurement In Mixtures Of Alkalizing Agents
    10/21/2014

    Proper measurement of pH is a key factor of corrosion risk surveillance in water-steam cycles.

  9. Case Study Of Swan Turbiwell Quarterly Calibrated Unit Versus Quarterly Verified Unit
    3/14/2014

    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.

  10. Smart Wireless Technology Solves Environmental Monitoring Challenge
    10/31/2013

    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.
