Tubular membrane MBR (ultrafiltration) technology is an external type, through the pump will be pumped into the membrane tube, membrane separation under the pressure drive, the effluent through the me......
The product principle
According to the location of membrane components, solid-liquid separation membrane bioreactor can be divided into external membrane bioreactor and built-in bioreactor.
External ultrafiltration membrane is a kind of membrane made of polymer material. The pore size of the external ultrafiltration membrane is very small, so the bacteria in the water and the colloid, rust, suspended matter, sediment, macromolecular organic matter, which are much larger than the bacteria, can be intercepted by the ultrafiltration membrane when they pass through, thus realizing the purification process.
The working principle of
The external UF is separated from the membrane module and the bioreactor. The mixed liquid in the bioreactor is pressurized by the circulating pump and hit to the filter end of the membrane module. Under the action of pressure, the liquid in the mixed liquid passes through the membrane and becomes the system treatment effluent. The solids and macromolecules are retained by the membrane and returned to the bioreactor with the concentrated solution.
The membrane filtration system consists of: UF inlet water pump, inlet water filter, membrane assembly, circulating pump, cleaning pump.
The characteristics of
Stable and reliable operation;
Membrane is easy to clean, replace and add;
Membrane flux is larger;
However, under general conditions, in order to reduce the deposition of pollutants on the membrane surface and prolong the cleaning cycle of the membrane, a circulating pump is needed to provide a higher cross flow velocity on the membrane surface, and the energy consumption is high.
The process parameters
The operating pressure is 0.11 ~ 0.6MPa;
When the temperature is less than 60℃, the membrane flux of the ultrafiltration membrane is 1 ~ 500.
