High quality reuse water by chemical-physical wastewater treatment.

Abstract

In recent years more communities are finding that their demand for water is overextending or approaching the limit of their existing water sup ply. As a result, the need for new water sources has increased. One method that can be used to augment conventional water sources to meet these community needs is wastewater reclamation. The sequence of treat ments usually followed to reclaim wastewater for reuse is made up of biological, chemical, and physical proc esses. The terminal unit process usu ally is activated carbon adsorption be cause it has been found to be an excel lent choice in terms of adequacy and economic feasibility. Since the waste water reclamation treatment is a se quence of pretreatments before acti vated carbon adsorption, the emphasis of this research was to optimize the activated carbon adsorption step by determining the proper pretreatment process. In this way the wastewater reclamation process could yield high quality water at maximum efficiency. This study, started in 1966, was di vided into two distinctly different ap
