Microfiltration
The Microfilter is the first stage of the treatment process. Raw untreated water is pumped through the Microfilter's 48 filters at up to 300 gallons per minute. The filters have a pore size of .2 microns or about 200 times finer than a human hair. The Microfilter is unique because it does not require chemical pretreatment. Every 30 minutes the filters are backwashed with high pressure air and water to flush the accumulated buildup from the filters' membranes.
Nanofiltration
The Nanofilter treats the water (filtrate) after the Microfilter. The Nanofilter is a 3-stage system that is 85% efficient. The 12 filters are able to remove molecular size contaminants such as salts, viruses, and large organic molecules that cause color in the product water. This configuration is becoming more popular in the water industry in meeting stricter water quality standards.
