Abstract : The work presented in this paper describes the results of a treatability study of wastewaters originating from a benzol plant in an upflow biotower (UBT). The wastewater constituents are the same as for coke oven wastewater, except that most of the constituents are present in some-what lower concentrations. The biotower used in this study is a biological treatment process developed by the Leopold Company and operates more or less like a reversed flow trickling filter. The tower is packed with random plastic medium, the influent flows upward and air is supplied by aeration through a filter underdrain system. This paper will present the results of the treatability of benzol plant wastewater in this reactor. The main purpose of this study was to determine the loading at which the phenol was virtually completely removed from the influent. The data obtained in this study will be compared with studies performed by other researchers with similar wastewater in activated sludge and with other types of fixed film reactors.
