The Treatment of Saline Wastewater Using a Two-Stage Contact Oxidation Method

Abstract

This paper introduces the treatment of saline organic wastewater using a two-stage contact oxidation method. The experiment was carried out to explore how several factors affect the results of the treatment such as salinity, organic loading and organic ingredients in influent. The experiment revealed the organic loading ranges within which the salinity had less effect on the treatment efficiencies when influent salinity was 25,000 ppm and 35,000 ppm respectively. Moreover there is a theoretical discussion on the effect of organic ingredients on the removal of organic substances from wastewater.
