Advanced Treatment of Effluents by Simultaneous Powdered Activated Carbon Adsorption and Flocculation

Abstract

In this research, an advanced tertiary treatment of municipal sewage treatment plant effluents, utilizing a simultaneous combination of adsorption on powdered activated carbon (PAC) and flocculation with aluminum sulfate, or ferric chloride, performed at the same reactor, was investigated. In order to understand the advantages of the two treatments together, the adsorption on PAC and the flocculation were studied separately, and subsequently, a simultaneous combination of both treatments was investigated. In the combined simultaneous PAC adsorption and flocculation in effluents, the optimal combinations of PAC and flocculant doses were established, generating very high quality water, and suitable for reuse of different goals.
