MBR

MBR Process:

 

 

Conventional Process:

 

 

■ Features and benifts

 · The effluent quality is better than the first level A criteria of the national discharge standard

 · High concentration sludge is easy to culture dominant microflora; has excellent resistance shock

   loading ability

 · Compact design; small occupation area

 · Technological parameter is easy to control ;can let Hydraulic retention time(HRT),and suspended

   sludge retention time(SRT) completely separated

 · Sludge production decrease. The cost of sludge disposal is reduced too.

 · Full process can be auto-control

 

 

■  Application

·Upgrade existing sewage treatment plants

·Treatment of industrial wastewater containing high concentration,poison,refractory like    pharmaceutical

  wastewater,chemical waster water,

·Reclaimed water reuse regions or places: residential landscape recirculating water, power plant recirculating

 cooling water.

·No drainage network regions wastewater treatment: tourism scenic area, highway service area ,traveling resort

·Small scale sewage treatment plants: residential area, hotels,office buildings

·Disposal sites for treating sludge

·Treatment and recycle of Landfill Leachate

Construction 

Requirements

Not easy to achieve modular design. 

It is better to build all system in one time.

Modular design. It is suit for stage 

construction, save cost.

Site 

Requirements

Restrain to site

No restrain to site. Can make ground type, 

semi-ground type and under ground type.

EffluentQuality

Reach the first level A criteria of the 

national discharge standard

 

Better quality than the first level A criteria

Large

Small

Water 

Productivity

Sand filter tank or actived carbon tank 

need to backwash frequently. Process

 itself will consume water, so producing 

water rate is low.

Backwashing is not required. Producing 

water rate is high.

Excess 

Activated 

Sludge 

Suldge production is high, the cost of 

sludge disposal is high too.

Sludge production decrease , the cost of 

sludge disposal is reduced too.

Chemical 

Sludge

Need to add many chemical reagent 

and produce chemical sludge. Easy 

to make secondary pollution.

No need to add chemical reagent, no 

chemical sludge.

Operation

Management

It is easy to have breakdowns because 

of complex mechanical structure. Need

professional person to maintain the system.

Simple mechanical structure and operating 

process. Full process can be auto-control. 

Operator only need a simple training.

Effluent 

Application

Limited application: water for toilet flushing , 

roadsprinkler and City green.

The effluent quality is good which can be 

widely used in toilet flushing water, roadspinkler 

water, city greening water, automobile washing, 

Construction site water and scenic environment 

water and so on.
