  • Oil/water separator and oil skimmer companies work together to help power generation facilities

    Power generation facilities depend on oil/water separators to separate oil from its waste water. While oil/water separators are a helpful component to a plant’s wastewater system, oil/water separators traditionally do not provide an efficient method of removing oil once it has been separated from the waste stream. Knowing what his customers were faced with, Dave Goding, president, Mercer ...
