220V MBR Wastewater Treatment Plant

Product Description

220V MBR Wastewater Treatment Plant

Membrane Bioreactor (MBR) type packaged sewage water treatment plants

FEATURES

• Pre-assembled, skid-mounted system reducing installation time and costs.
• Space saving, compact design.
• Advanced nitrogen and phosphorus removal.
• Hollow fiber/Flat-sheet membrane modules delivering greater filtration performance and reducing aeration energy.
• Pre-programmed, user-friendly controls for reliable operation and minimal operator attention.
• Title 22 approved ensuring high quality effluent (<0.2 NTU).

Technological Process:

Sewage → Grille → Regulating pond → MBR Bioreactor → Discharge(reuse)

1. Temperature: 5ºC~45ºC, average membrane aperture 0.10 μm.

2. PH: 2~12, membrane thickness: 40μm.

3. Outlet water turbidity: <1 NTU , outlet water SS <1mg/L.

4. Membrane area: 8m2, advised gas-water ratio: 25:1~30:1.

5. Operating pressure: -0.01 ~ -0.03MPa.

Membrane Bioreactor (MBR) type packaged sewage treatment plants are designed to treat domestic strength sewage, to achieve “Class A+” treated effluent, suitable for reuse in “risk category high” applications or for discharge to sensitive environments.

 

The standard treatment process includes influent screening, balance tank mixing, anoxic & aerobic treatment, flat sheet membrane filtration with air scouring and CIP system, and effluent disinfection (hypochlorite dosing). Membrane bioreactors are constructed of corrosion resistant FRP, and are self-contained, modular systems for easy deployment to remote locations.

More features:

1. Because of the high-efficiency solid-liquid separation, it can efficiently remove the SS, colloidal material and dead microbe in the sewage, no need sedimentation tank, or filter device, nor other solid-liquid separation device.

2. The MBR can make the biomass in biological treatment unit maintain high concentration, thus highly improve the volume loading. Meanwhile, the high efficient membrane separation can shorten the HRT. The device is with a compact structure and small space occupation.

3. MBR can filter out bacteria, part of the harmful material such as virus, it can obviously save dosing disinfection dosage, greatly improve the quality of the output water and reduce the operating cost and widen the scope of application of water.

4. Due to the strong interception function of MBR, it can keep the microbe in the reactor to avoid the loss of all kinds of microbe groups, which is good for the growth of the bacteria (such as the nitrifying bacteria), at the same time, it can lengthen the residence time of difficult degradable macromolecule organics to improve the decomposition so as to make the metabolic system process smoothly. The system has a strong impact resistance and wide suitability.

5. It can realize the completely separation of HRT and SRT. By the extended aeration, it can consume the organics, it can theoretically achieve the effect of no excess sludge emissions, thus reduce the surplus sludge treatment costs significantly.

6. The unique mode of operation makes the membrane surface no blocking, and the cleaning interval time is long. The way to clean the membrane is easy, since the membrane module can be separately cleaned, thus, the maintenance is convenience and simple.

The module design make the machine flexible, it is easy to expand the volume.

Advantages:

1) can save 50% area compare with the traditional process

2)Can treat high MLSS waste water (<10g/L), with long residence time for sludge(less30 days)

3)Steady Producing water quality for different water quality

4)Output Sludge value is low , lower the treatment sludge fee

5)Low consumption , cleaning easy ,and low operation cost

6)The equipment is carbon steel Integration , biological oxidation and membrane reaction and back wash operate in same integration sewage treatment plant

(7)Compare the concrete structure , MBR Integration system /Package Sewage treatment Plant low occupy

area , and construction is easy . Only need do a base

(8)Can put underground , and surface can do greening
