ABSTRACT:
Large volumes of waste water stream containing oil, greases, sometimes ferric ions, and dissolved contaminant hydrocarbons such as BTEX are rapidly treated in two stages. Initially, the oils and greases are separated, then the dissolved contaminant hydrocarbons are removed by countercurrent adsorption on powdered resinous polymeric adsorbents in an exchange zone, preferably in the absence of ferric ions. The contaminant laden adsorbents are regenerated and continuously recycled to the exchange zone.
