What are your main sources for process water, and how do you treat it? We get our raw process water from industrial water supply, ground water, and surface water sources. We treat our process water using reverse osmosis (RO), to make it suitable for use in manufacturing processes and equipment cleaning, as well as for drinking water. The RO reject is of high-enough quality - below 2100 mg/L total dissolved solids (TDS) - that we can use it for non-process applications such as landscaping.
