### action | chemical action:

Chlorination
* also oxidizes iron, manganese and hydrogen sulfide so they can be filtered out
  - removes soluble iron, manganese and hydrogen sulfide from water
  - treats for organically-related taste, color, and odor problems
* can disinfect and destroy harmful bacteria and other organisms.
* causes the light-absorbing properties of solutions to change.
* common method of disinfecting drinking water.
* destroys all animal and microbial life, leaving no trace of itself afterwards.
* disinfects the water and finally makes it safe for distribution
  - water, killing bacteria, viruses and protozoa that transmit disease
* is an alternative to powdering medical gloves, so that they can be donned.
* is an effective measure against microbial activity
  - treatment for both types of clogging
  - apparently as natural a biological process as blood clotting or salivation
  - chemical processes
  - currently a standard method of pool and spa disinfection
  - effective in killing the parasite, as is boiling water
  - imperative to keep public water supplies free of most deadly pathogens
  - important to improving several treatment processes
  - more effective as water temperature increases
  - necessary for two reasons
  - particularly effective in preventing recontamination during distribution
  - presently the most common treatment for zebra mussels
* is the final step for most wastewater treatment plants
  - injection of chlorine gas into the water and assures potability
  - most common disinfection method
* is the most common method for treating bacterial slimes
  - of disinfecting potable water
  - of chemical intermediate reactions in the chemical process industry
* is the most widely used method for disinfecting drinking water
  - for purifying municipal water supplies
  - recognized and accepted method of treating water supplies throughout the world
  - standard by which other disinfection procedures are judged
* is used almost universally in U.S. public water supplies
  - extensively by municipal water treatment plants to disinfect water
  - to maximize the efficiency of fine filtration processes
* kills any remaining microorganisms
  - the microorganisms and keeps the filter going longer
* means the addition of a chlorine compound or chlorine gas to water.
* procedure used to disinfect a water well contaminated with bacteria.
* process that constitutes purification of water.
* produces chlorinated organic materials including a very small amount of dioxins.
* provides disinfection of viruses and residual maintenance for the distribution system.
* uses liquid chlorine bleach to kill microorganisms.

### action | chemical action | chlorination:

Shock chlorination
* introduces very high levels of chlorine into a water system.
* is recommended when coliform bacteria are detected, or after system repairs.
* is the preferred method for eliminating bacterial contamination in wells
  - procedure for cleaning and sanitizing a well or spring with chlorine
  - used to control bacteria in water wells
* way to protect a private well from coliform, iron, and sulfur bacteria.

Decarboxylation
* occurs during Glycolysis.
* requires electron shift away from the carboxylate.

### action | chemical action:

Desalination
* are chemical processes
  - separatings
* is also effective in removing other chemicals like fluoride, arsenic and iron
  - an experiment that is neither necessary nor appropriate
  - more expensive than most other methods of obtaining fresh water
* is the process of making salt water fit to drink
  - removal of salt from seawater
  - very energy intensive
* makes a significant contribution to Saudi Arabia's overall power generation.
* process by which salts are removed from seawater.
* scientifically simple process.
* takes place in the channel centre where electroneutrality is present.
* turns salt water from the Gulf of Mexico into drinking water.
