MBR (Membrane Bioreactor) is a water treatment system which uses biological treatment in membrane filtration technology. Compared to conventional sludge treatment systems, the Chempure Compact MBR is more compact and makes it possible to product high-quality treated water.

What is MBR (Membrane Bioreactor) ?

Combining activated sludge treatment and submerged membrane filtration process makes highly concentrated activated sludge treatment possible. Our low-cost system is easy to maintain, save space, and is suitable for small-scale sewage treatment to obtain high quality treated water.

A typical configuration is depicted below. Air generated from air blower is diffused into the bottom of the reactor vessel. The oxygen supply is automatically adjusted to maintain the proper dissolved oxygen level in the vessel. A high concentration of biomass develops because of the large media surface area, abundant oxygen and optimized mass transfer conditions. Excess biomass is automatically sheared at the discharge point for removal.

Submem is based on the conventional biological wastewater process, but the separation of micro organisms is performed by submerged membrane filtration. Wastewater is pumped into the bioreactor and oxygen is dissolved into the bioreactor by means of fine bubble aerators located at the bottom of the reactor.

The submerged membranes are located in a separate tank beside the bioreactor where the aerated sewage is pumped to the MBR tank. The permeate pumps draws the filtered water through the modules. It goes into the back flush mode based on a timer sequence. The concentrated biomass in the MBR tank flows back to the aeration tank during back flush and maintains a high MLSS in the aeration tank. Excess sludge is withdrawn periodically.

CrossMem is based on the conventional biological wastewater process, but the separation of micro organisms is performed by cross flow filtration. Wastewater is pumped into the bioreactor. Oxygen is dissolved into the bioreactor by means of fine bubble aerators located at the bottom of the reactor. The mixture of biomass is continuously circulated through a membrane filtration unit. The filtration unit consists of series of several ultra-filtration membrane modules.

A membrane module contains several hollow membranes which form the filter unit. The biomass mixture is pumped at high velocity through the membrane tube. High velocity is required for the constant cleaning (by turbulence) of the wall of the tube, which is the actual filtering membrane. The membrane is permeable to water and dissolved compounds, but retains the biomass and other suspended matter. The pressure on the feed of the biomass mixture is the driving force for filtration.
