MBR

Membrane technology has advanced significantly in the past 20 years for both water purification and wastewater treatment. Today, membrane-based systems have become the preferredt echnology for most of water purification and wastewater treatment applications: cod,bod removal,Cryptosporidium and Giardia control, color or suspended solids removal, etc.
The combination of membranes with the activated sludge process has redefined basic sewage & wastewater treatment approach, optimizing the biological treatment operation and yielding a treated effluent that is ideal for reuse. Key advances in membrane technology are at the leading edge of this trend:

Uncoupling HRT and SRT

A significant advantage of the membrane bioreactor process is that the sludge solids are completely retained in the bioreactor.  This means the solids retention time (SRT) in the bioreactor can be completely controlled separately from the hydraulic retention time (HRT).

This is different from the CAS process, where the flocculant solids that make up the biomass have to be allowed to grow in size to the point where they can be settled out in the secondary clarifier. In a CAS, the HRT and SRT are therefore coupled, since the floc size and thus its settlability relate to the HRT.

High quality effluent

Membrane’s pore size (0.03 or 0.1 µm) ensure that the treated effluent is of very high clarity and significantly reduced pathogen concentration. MBR processes provide a substantially clarified and disinfected effluent of high enough quality to be discharged to sensitive receiving bodies or to be reclaimed for applications such as urban irrigation, utilities or toilet flushing. 

Small footprint

The retention of the solids and the increase in SRT to generate higher biomass solids concentrations also impacts on the plant footprint. The increased concentrations mean that the same total mass of solids is contained in a smaller volume, such that the footprint is smaller.

Better biotreatment

Lastly, the longer solids retention times tend to provide better biotreatment overall. The conditions encourage the development of the slower-growing microorganisms, specifically nitrifiers. MBRs are especially effective at the biological removal of ammonia (nitrification).

Automatic simplest operation

A STP/WWTP with MBR can be run continuously with PLC control system. To get the most simplest operation. We have launched standard SIEMENS PLC system and SCADA System and SMS alarm etc. You can control and monitor system at anywhere and anytime only with a internet service.
