What is Water Purification?

WaterVelodyne Systems has manufactured top of the line chemical feed systems for more than 25 years. Utilizing chemicals to purify water dates back the late 1800’s. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Purifying water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi, as well as reducing the amount of a range of dissolved and particulate material derived from the surfaces that come from runoff due to rain.

The standards for drinking water quality are typically set by governments or by international standards. These standards usually include minimum and maximum concentrations of contaminants, depending on the intended purpose of water use.

Some Treatment types Velodyne is involved in:

  • pH adjustment: utilizing a lime, soda ash, or sodium hydroxide feed system to raise the pH during the process if the water is acidic.
  • Coagulation/Flocculation: utilizing polymer activation systems to aid coagulants, when the organic polymers are added to water with particulates, the high molecular weight compounds adsorb onto particle surfaces and through interparticle bridging coalesce with other particles to form floc.
  • Disinfection: utilizing chlorine tablets to create a solution for disinfecting and removal of bacterial pathogens which may be present within a water distribution system.  Providing a residual dose of disinfectant to inhibit bacterial growth within the processing equipment and  storage facilities.
  • Activated Carbon: commonly used to treat taste and odor issues.

Velodyne Systems strives to provide quality products that help bring safe drinking water to our community, state, natation and people all around the globe.
