Pool Info: Chitosan Water Treatment

Chitosan Water Treatment



Chitin (pronounced kite-in) came into being in the 1970's when the EPA ordered fishing companies to stop dumping the shells of crabs and lobsters back into the ocean. Researchers discovered that the chitin contained in the shells had properties that could be applicable in a variety of industrial uses. Similar to cellulose, chitin is a naturally occurring polymer. It is also the only naturally occurring polyelectrolyte.

The combination of chitin's remarkable properties makes it an extremely versatile pool chemical. Chitin is natural, non toxic, non allergenic, anti microbial, and bio degradable. It has a strong positive charge, which allows it to bind easily with negatively charged surfaces or materials; including metals and any microcontaminants in the pool water.

For pool & spa use, chitin is produced in a patented formula by the Vanson company, marketed under the name Sea-Klear. The properties of chitin enable it to attach itself to a variety of organic contaminants, minerals, metals, and oils. The result is clearer, cleaner water with less staining and scaling. Vanson also notes a beneficial effect on the filtering medium, whether sand, D.E., or cartridge. The efficiency of your filtering improves with regular use as chitin's natural coagulants help the filter to trap more dirt and debris.

Sea-Klear is added as a liquid directly to the pool. It's touted as an all in one replacement for clarifiers, filter aids, stain & scale magnets, and enzymes. The pool janitor has used Sea-Klear with great result, and can recommend it. Sea-Klear is compatible with all types of pool chemicals, and is a great addition to any sanitizing program.
