FAQ

To assist your engineering and procurement teams in their technical evaluation, we have compiled answers to the most critical operational questions regarding our MBR technology.

• Q1: How does the MBR system handle fluctuating inlet water quality and sudden shock loads?
  A: The system maintains an exceptionally high Mixed Liquor Suspended Solids (MLSS) concentration (up to 15 g/L). This dense, active biomass acts as a powerful biological buffer. When a shock load of high-concentration organics enters the reactor, the robust microbial community rapidly absorbs and degrades the excess pollutants, ensuring the final effluent quality remains completely stable and unaffected.

• Q2: What is the expected lifespan of the PVDF membrane modules under continuous industrial use?
  A: Our membranes are manufactured using a premium PVDF alloy with a reinforced inner structure. This design provides extreme mechanical strength and chemical resistance. With proper adherence to our recommended gas-water scouring ratios and routine chemical cleaning protocols, the membrane modules typically deliver a reliable operational lifespan of 5 to 7 years, even in challenging industrial wastewater environments.

• Q3: Can this MBR machine be retrofitted into our existing wastewater treatment facility?
  A: Absolutely. The highly modular and compact nature of our equipment makes it ideal for retrofitting. It can be seamlessly integrated into existing aeration tanks or deployed as a standalone containerized unit to instantly boost the capacity and effluent quality of an older plant, all without requiring additional land acquisition or major civil construction.

• Q4: How exactly does the system achieve near-zero excess sludge emissions?
  A: The MBR process completely separates the Hydraulic Retention Time (HRT) from the Sludge Retention Time (SRT). By maintaining a very long SRT (up to 60 days), the microorganisms enter a phase of endogenous respiration, where they consume cellular material to sustain themselves. This biological cannibalization drastically reduces the net yield of new sludge, cutting your sludge dewatering and disposal costs by a significant margin.

• Q5: What are the specific power requirements and energy consumption metrics for this unit?
  A: The system is engineered for maximum energy efficiency. The membrane suction pumps operate at a very low trans-membrane pressure (-0.01 to -0.03 MPa), requiring minimal electrical draw. Furthermore, the optimized aeration system serves a dual purpose: providing oxygen to the biomass and simultaneously scouring the membranes to prevent fouling. This synergistic design ensures the overall kilowatt-hour per cubic meter (kWh/m³) treated remains highly competitive.
