These systems may be purchased in standard configurations, or may be custom designed to meet the specific needs of a customer.

Frexes is prepared to tackle the toughest water problems, such as the removal of heavy metals from a volcanic lake, or solidified organic waste in the settlement lagoon of a chicken processing plant, or the manure by-product of a pig farm. All of these projects, and others, have been addressed successfully. The latest scientific methods are incorporated into Frexes systems - ozone treatment, sophisticated bacteria cultures, and advanced filtration.
