Use of Membrane Bioreactor Process for Wastewater Treatment: Case Study

Carlos A. Ortiz, Ph.D., Alma Manga Civil Engineering Technology Southern Polytechnic State University

Abstract

Paulding County in the State of Georgia has experienced approximately a 96% population increase in the last decade [1]. As a result of this population growth the need for increasing wastewater treatment capacity and improving effluent quality have become one of the main priorities for the Public Works Department (PWD). In an effort to improve the existing capacity of one of the existing wastewater treatment plants, the PWD approached the Civil Engineering Technology (CET) program at Southern Polytechnic State University to conduct a pilot-scale evaluation of an immerse membrane system (or membrane bioreactor) for municipal wastewater treatment.

A three-month study was conducted to evaluate the efficiency of a membrane bioreactor. This work was conducted on a 918 L/h pilot plant comprised of an anoxic tank, an aeration tank and four membrane modules. This pilot system was operated in parallel with the full-size wastewater treatment plant to determine and compare removal efficiencies for BOD, COD, TSS, TKN, NH3, NO3, PO4 and fecal coliforms. With the exception of nitrates, phosphates and fecal coliforms, all the analyses were performed at the CET environmental laboratory. The pilot system produced an effluent containing BOD concentrations less than 1.0 mg/L and turbidity readings below 1.0 NTU.

Introduction

Trussell [2] and Adham [3] have reported that membrane bioreactor systems can produce high quality effluent with respect to BOD, TSS and fecal coliform count. The objective of this study was to evaluate the efficiency of the membrane system under two different mixed liquor conditions and determine the best operating conditions; while comparing the performance of the pilot system with the existing treatment facility.

The pilot system designed by US Filter and used in this study, consisted of a 3028-L (800 gal) anoxic tank, a 6814-L (1800 gal) aeration tank, and four membrane modules with a surface area
