Process Modeling of Pulp and Paper Wastewater Treatment Ponds

Abstract

A new commercially available pond model was used to develop and dynamically calibrate a process model of a pulp and paper mill wastewater treatment facility. The process consists of primary treatment and four treatment ponds operated in series prior to discharge. The model showed very good calibration of carbonaceous material, nitrogenous parameters, and dissolved oxygen and was used to predict and optimize treatment performance, aeration demand, and help with aeration equipment sizing.

Treatability Testing and Design of Unique Bioreactor for Leachate Odor Control

Abstract

As a prerequisite for discharge to the City of Dayton's wastewater collection system, the Stony Hollow Landfill located in Dayton, Ohio is required to provide pretreatment of its leachate to prevent increased odors within the City's collection system and at the City's Water Reclamation Facility (WRF). Leachate and other liquids produced at the Stony Hollow Landfill contain relatively high concentrations of organic compounds, including some that may contribute to odors such as volatile fatty acids, acetone, methyl ethyl ketone, and phenol. Several technologies were identified and evaluated initially. Two technologies were ultimately selected for further evaluation on a laboratory scale: advanced oxidation using Fenton's reagent and hydrogen peroxide to generate hydroxyl radicals for the oxidation of odor causing compounds; and biological treatment using biologically active aerated treatment (BAAT). BAAT is a continuous flow, aerobic suspended growth biological treatment process. The technology is unique because biomass is not separated from the effluent; therefore, the bioreactor solids retention time (SRT) is the same as the hydraulic retention time (HRT).
