Introduction

The Membrane Bioreactor Laboratory (MBR) was inaugurated in January 2016 as a pilot-scale plant as an advanced wastewater treatment technology. Combining biological treatment processes with membrane filtration, this state-of-the-art facility is capable of reclaiming up to 50 m³ of wastewater per day.

Major research activities

  1. .Membrane Bioreactor Laboratory (MBR):
  • Application: Utilized for domestic and residential wastewater treatment, recycling and reuse for horticulture, landscaping, and other non-portable purposes.
  •  Components:
    Biological Reactor: Microorganisms degrade organic matter in the wastewater.
    Membrane Tank: Ultrafiltration membranes separate treated water from activated sludge
Advantages
  •  Water Quality: Meets stringent standards, producing effluent with less than 1 Naphalometric Turbidity Unit (NTU).
  • Reusability: Suitable for reuse in horticulture and landscaping, meeting 100% of NUST campus horticulture demand in winter and 50% in summer.
  • Research Demonstration: Represents the most advanced wastewater engineering applications.
  • Space Efficiency: Requires significantly less land than natural treatment systems like wetlands.
  • High-Quality Reclaimed Water: Produces non-restricted reclaimed water, ideal for landscaping and horticulture.
  •  Compact Design: Requires less space than conventional treatment systems.
  • Lower Sludge Production: Generates less sludge compared to conventional treatment methods.
General Working Principle
  1. Influent Wastewater: Wastewater enters the bioreactor and mixes with activated sludge (microorganisms).
  2.  Biological Treatment: Microorganisms break down organic pollutants in the wastewater.
  3. Membrane Filtration: The mixture is filtered through membranes, retaining the biomass (sludge) while allowing treated water to pass through.
  4.  Effluent Discharge or Reuse: Clean water is either discharged or reused, and the sludge is recycled or disposed of.
