Abstract

Population growth and depletion of high quality fresh water supplies have led to an increased interest in wastewater reuse to augment potable water supplies either directly or indirectly so this paper presents a simple experimental set-up was used to study the treatability aspect of synthetic waste water. Three types of systems: i) conventional anaerobic baffled reactor (ABR (A)), ii) anaerobic baffled reactor with sponge bio-film (ABR (B)), iii) anaerobic baffled reactor with fiber bio-film (ABR (C)), where experimented under different COD (0-5000 mg/l) in the first steps, with flow rate 38 l/d and pH value 8.5. pH effect on treatability was also investigated. The main objective of this study was to investigate the behavior of three reactors and verify the use of bio-film in improving treatability, to promote theses the use of two types of bio-film sponge and fiber. Many significant factors were considered such as: temperatures, number of baffled in reactor, shape baffled and location of reactor to avoid lighting. For all tested reactors, influent COD concentration, influent pH, temperature in the reactor, effluent COD concentration, effluent pH and flow rate, in the start-up stage. Test results revealed the ABR C scenario gave the highest COD % removal comparing with the other two scenarios. Results showed that decreasing pH value had an adverse effect on treatment efficiency for all cases.
