The MBR Plant The MBR systems are one of the fastest growing water treatment technologies in the world. In many instances they can replace conventional filtration plants. WEC Projects (Pty) Ltd MBR Plants incorporate biological treatment technologies with submerged membrane technologies. These technologies can be utilised in potable, waste water and industrial applications. Definition: Membrane Bio-Reactor Treatment Plants are those which remove dissolved and suspended organic and chemical constituents through biodegradation, as well as suspended matter through physical separation where effluent is treated through a series of submerged membranes. Increasingly stricter legislation with regard to waste water treatment especially in industrialized nations has pushed the boundaries of activated sludge treatment plant design. Improved treatment process are required for the removal of higher percentages of nutrients, suspended solids and bacteria etc. WEC Projects MBR systems include process advancements from typical activated sludge treatment plants and produce better quality treated effluent. Membrane Bioreactors combine biological process steps as well as submerged membrane technology. They replace the aeration and settling components of a traditional biological system with one process step. The size of the membrane pores significantly affect the quality of the treatment. Micro-filtration membranes effectively remove particles while RO membranes eliminate macromolecular fractions. They offer the following advantages: Smaller footprint The membranes are highly effective for removal of suspended solids Reduced hydraulic retention times Modular expandability Less susceptible to flow variations Less odour Simple but hi-tech Absolute dependence of disinfection is reduced Less frequent cleaning More consistent high quality effluent The submerged membranes are housed within a biological reactor with the effluent drawn through the membranes via high pressure vacuum. Suspended solids remain behind in the biological reactor. In the past membrane technology was not commonly utilized in the treatment of sewage. Today however it is becoming more common. Through increased research and development you now find MBR installations treating incoming effluent of up to 13,000m3/d Membrane failures have reportedly been low and capital and operational costs have reduced over time and will probably continue to do so. The MBR option is becoming a more realistic option each year WEC Projects is a proud pinoneer. Top	Interesting Facts "Raindrops are not tear-shaped.
