The cost-effectiveness of MBR in the wastewater field has been greatly improved
The cost performance of MBR technology in the field of sewage treatment has indeed been significantly improved, mainly reflected in the following aspects:
1. Excellent treatment effect:
MBR effluent quality is very good, COD < 50mg/L, BOD5 < 10mg/L, SS < 10mg/L, ammonia nitrogen < 5mg/L, E. coli count < 3/L, can directly meet the water reuse standard.
It has a high treatment efficiency for various pollutants, including organic matter that is difficult to biodegrade.
2. Small covering area:
The MBR process has a compact structure and occupies only 1/3-1/2 of the traditional process.
It eliminates the need for secondary sedimentation tanks and other structures, greatly saving space.
3. Flexible operation:
The process can be flexibly adjusted according to the influent water quality, with strong adaptability.
High degree of automation, easy to operate and maintain.
4. Low sludge production:
Due to the high concentration of biological phase and long sludge age, the residual sludge production is low.
5. Improved technical maturity:
After years of development, MBR technology has been widely used at home and abroad.
The performance of membrane materials and membrane components has been continuously improved, and the service life has been extended.
6. Cost reduction:
With the development of technology and the expansion of application scale, the construction and operation costs of MBR are gradually reduced.
Although it is still higher than traditional processes, considering factors such as effluent water quality and land occupation, the cost performance has been greatly improved.
7. Wide range of applications:
It can be used in many fields such as urban sewage treatment, industrial wastewater treatment, and purification of slightly polluted drinking water.
In general, MBR technology has obvious advantages in treatment effect, covering area, and operational flexibility. With the continuous advancement of technology and the gradual reduction of costs, its cost-effectiveness in the field of sewage treatment has been greatly improved, making it an increasingly competitive sewage treatment technology.
