Drinking Water Application Notes

  1. Preliminary Assessment Of Water Quality In Riviera Grise Near Port-Au-Prince, Haiti 10/17/2012

    The Riviera Grise drains water from the Cul-de-Sac watershed, Haiti, which covers most of the rural areas along the flood plains and areas that extend into steep hillsides. It also covers urban areas of Port-Au-Prince, the capital city of Haiti.

  2. The Role Of Zeta Potential In Water Treatment Process Control 5/27/2020

    Physical processes such as sedimentation, flotation and filtration remain at the heart of most process trains for the treatment of water and wastewater flows.

  3. Dissolved Oxygen Measurement 11/11/2013

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  4. Flow Meter Enhances Chlorination System Performance For Municipal Water Department 12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.

  5. How To Install A Submersible Pump In Discharge Tubes 11/28/2012

    In the fields of water and waste water technology, submersible pumps represent a viable economic and technical alternative to conventional, dry-installed pumps. In particular, they offer a number of handling advantages during maintenance and installation work.

  6. Groundwater Remediation 12/1/2020

    Good quality groundwater is an important natural resource. It provides drinking water for the public as well as process water for industrial applications. Groundwater can become contaminated through a number of ways including improper handling of process chemicals or disposal of wastes.

  7. Biofouling Control In Cooling Towers With A Halogen Stabilizer 10/22/2020

    Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

  8. Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCA 2/19/2014

    The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.

  9. Determination Of Hexanal In Foods Utilizing Dynamic Headspace 4/9/2015

    Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

  10. Application Bulletin: Reverse Osmosis 3/19/2008

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
