Title: | Wastewater treatment using a novel pilot-scale membrane bioreactor | Authors: | Luong Tan Vu | Keywords: | Wastewater;Treatment process;Environment;Water-reuse system;Membrane bioreactor (MBR) technology;Lab-scale | Issue Date: | 2014 | Publisher: | Vietnamese-German University | Abstract: | Wastewater treatment process has become a significant issue for operation and environment in the industrial sector. Sustainable development in industry can be effective by highly appreciating the water-reuse system. The textile and laundry industries can be considered as intensive factories in water process because every day they release a high amount of wastewater. Membrane technology has been recently applied in wastewater treatment together with conventional treatment. Therefore, membrane technology can be regarded as a promising technology for waste treatment and reuse in textile and laundry industries [1]. Membrane bioreactor (MBR) technology is a combination of the conventional biological sludge process, a wastewater treatment process characterized by the suspended growth of biomass, with a micro- or ultrafiltration membrane system [2]. The advantages of MBR are its ability to biodegrade the waste compounds and separate the treated water from the mixed liquor due to the small pore diameter of the membrane. The bacteria and suspended solids can be kept out of the effluent with the membrane having a pore diameter from 0.01 to 0.1μm. The target of this thesis is to revamp an existing MBR system from a single to a double membrane module. Then, trials using a lab-scale MBR were carried out with a model textile wastewater. The general aim of the follow up research is to further optimize the bioreactor process and the ability to compare the performance of two commercial membrane modules. In long term, commercial and novel nano-scale membrane also can be compared. |
