Skimming oily wastewater

Regardless of application, the primary reasons to recycle oily wastewater are economics and the desire to be a good environmental neighbor. Because economics plays such a pivotal role, the recycling method has to be cost effective over its entire life cycle. That includes original purchase price, installation costs, operating expense and maintenance costs. Cost effectiveness also is measured by the residual oil concentration in the wastewater. Oil skimming can be evaluated as a standalone treatment method, as well as a pretreatment method for more exotic oil/water separation technologies.
