   The Thermo Scientific Orion AQUAfast® AQ3700 Colorimeter comes programmed with methods for testing nutrients. By Thermo Fisher Scientific
2. Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
   5/31/2011
   Total bound nitrogen (TN_b) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TN_b measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

3. Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
   12/15/2017

   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.

4. Underground Treatment Of Airport Deicing Fluid
   9/15/2011
   While keeping air flight safe, airports and airlines are also obliged to clean up after themselves and protect nearby streams and water bodies. And due to increasing chemical usage and looming regulations, some airports will need to invest in significant infrastructure upgrades to capture and treat stormwater contaminated with deicing fluid.

5. Optimizing Air Flows To Aeration Basins
   4/17/2014

   As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

6. Bristol-Myers Squibb Works Hard To Be A Good Neighbor
   4/18/2017

   Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.

7. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
   7/6/2017

   ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

8. 3M™ Liqui-Cel™ Membrane Contactor Technology Being Evaluated For Dissolved Gas Removal From Water In Many Hydrocarbon Processes
   6/28/2017

   The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. In many hydrocarbon recovery and water processes, degassing is necessary in order to minimize environmental impact, improve operating efficiency, avoid process issues and help protect system components.

9. Application Note: Building A Baseline In Florida
   5/25/2006
   The Florida Department of Environmental Protection (DEP) knows that establishing dissolved oxygen (DO) and nutrient criteria for the state’s water bodies is a challenge – both scientifically and politically
10. Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
    8/4/2011
    Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.
