What is Organic Contamination And How To Remove It

Removing Organic Contamination

Organic contaminants include pesticides, herbicides,, decayed plant and animal tissues, gasoline (centuries old decayed plant and animal tissue), and plasticizers (made from petroleum products). Plasticizers leach out of plumbing lines, fittings and storage tanks, so ironically, the purification system itself can contaminate the water if it is not properly constructed.

The absence of organic substances is especially important in research that involves tissue cultures, and also in HPLC (high performance liquid chromatography), gas chromatography, electrophoresis, and fluoroscopy.

Organics are removed using a combination of Activated Carbon, Ultrafiltration, Reverse Osmosis, Organic Scavenging Filters and Ozone Injection.

Organic levels are measured in p.p.b. or p.p.m or TOC (Total Organic Carbon)
