Product Detail of membrane for MBR system wastewater treatment

Membrane bioreactor MBR sewage treatment - membrane filtration 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 of we these mbr membrane manufacturers 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 for mbr sewage treatment

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 MBR system wastewater treatment

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 sewage treatment plant/wastewater treatment plant 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.

The wastewater membrane filtration technology is the most popular system in industrial application. It is being used for several years in the industrial field to purify the polluted water come from industries. It is considered the most important part of the industry in order to waste the water after processing into the lake.
Why Wastewater membrane Filtration Technology is used?
We all know that industries use different kind of chemicals and harmful substances that are severe for human health. These chemicals can easily cause dreadful diseases to anybody if they get into their stomach or their internal body system in any case.
During the production or any other process of the item in an industry takes place, then these chemicals are highly utilized on it. These chemicals remain in a particular store in the form of water that is discharged into the lakes and rivers after the process is being done.
Here is the time where wastewater membrane filtration technology is being used. Before discharging the wastewater containing chemicals into lakes and rivers, it is perfectly filtered so that water does not pollute because of it. All of these chemicals and harmful substances are extracted from the water by wastewater membrane filtration technology and then disposed into the lakes. In this way, the water in lakes remain safe to drink and also the wastage of industries is discharged.
Working of wastewater membrane filtration technology
Wastewater membrane filtration technology includes the utilization of membrane technology for the division of biomolecules and particles for the centralization of procedure liquids. During division, a semi-porous membrane goes about as a particular obstruction holding the atoms/particles greater than the pore size, while enabling the littler particles to saturate through the pores. Wastewater membrane filtration procedures can be recognized based on the kind of power driving the device through the membrane, and are named by the measure of the pores in the filter.
There are 3 basic kinds of wastewater membrane filtration process-based pore sizes and particle sizes. All of them are as follows:
• Microfiltration
Microfiltration membranes are very cost-effective to use because of low energy utilization. They additionally have the benefit of wiping out the successive substitution and transfer of the cartridges and different consumables utilized in conventional impasse filtration. Microfiltration is utilized on feed streams where the point is to expel little breadth scattered solids, for example, microorganisms, oil globules and fat without influencing the parity of the parts broke up inside the stream.
• Ultrafiltration
Ultrafiltration utilizes membranes in which the pores are fairly littler, with a slice off range from 1,000 to 100,000 Molecular Weight, and where the connected weight is generally low. Sugars, salts, natural acids, and littler peptides go through the pores of the membrane, while fats, proteins, and polysaccharides don't. Utilizing proper ultrafiltration membranes additionally makes it conceivable to isolate a feed stream into two particular streams. Each contains broke up segments with various molecular weights.
• Nanofiltration
Nanofiltration utilizes membranes with pores that are considerably littler. Working at heights of up to 50 bar, little particles go through, while bigger particles and most natural components don't. These nanofiltration components are utilized for the high return focus and demineralization of items like ultrafiltration permeate and whey. These extraordinary membranes are utilized for sifting through huge salts with a valence more than 2, while little monovalent salts go into the saturate. They can likewise be utilized in creating low-liquor drinks, on the grounds that the liquor components go through the membrane, while the fragrance and color stay in the retentate.
