Aerobic Submerged Membrane Bioreactor for the Treatment High Strength Wastewater

    Project Code: 135
    MBR is a technology in water and wastewater treatment, effective in treating a variety of strength ranges and compound of wastewater. MBR is a hybrid system, consists of biological treatment and filtration. MBR is also known as an alternative for conventional activated sludge (CAS) treatment where clarifier is removed and substituted with membrane to overcome settleability problem when undesired biomass is formed
Project Overview

Industries are facing a critical issue in complying with the stringent water discharge requirement. Generally, wastewater comes from a variety of streams, for instance, from production line, cooling tower or boiler that content diverse substances (i.e. organic and inorganic compounds, virus, bacteria and toxic compound). These diverse substances challenge the ability of a conventional biological treatment method to treat those substances due to low biomass body strength.  High strength industrial wastewaters have a big impact on pipelines and equipment for boiler, cooling water, irrigation, maintenance and environment. These contaminants lead to clogging, corrosion, scale formation, biological growth and foaming in the pipelines and equipment, which require high maintenance cost.

Membrane bioreactor (MBR) is not a new technology in water and wastewater treatment but the capability in treating wastewa- ter cannot be disputed. MBR gives high performance in treating water besides having small footprints compared to con- ventional activated sludge where clarifiers are eliminated.  Generally, MBR produces high quality effluent, is good in removing organic and inorganic contaminants, capable of resisting high organic loading and generates less sludge.
