Water Contaminant Treatments

TOC

Drinking Water Sources of TOC

TOC (Total Organic Carbon) is a measurement to track the overall organic content of water. The organic content of the water will appear on the water analysis as C (carbon). The TOC test is the most common test performed to obtain an indication of the organic content of the water.

Treatment of TOC

Activated carbon is generally used to remove organics, color, and taste-and-odor causing compounds. The contact time and service flow rate dictate the size of the carbon filter. When removing organics, restrict flow rates to 2 gpm per square foot of the filter bed. Reverse osmosis will remove 98 to 99% of the organics in the water. Ultrafiltration (TJF) and nanofiltration (NF) have both been proven to remove organics. Anion exchange resin also retains organics, but periodically needs cleaning.
