6. Advanced Treatment Technologies
Overview
• Biological Treatment
Using microorganisms to break down pollutants, converting them into harmless substances, a
natural and sustainable approach to wastewater treatment.
• Membrane Bioreactors (MBR)
Integrating membrane filtration with biological treatment, efficiently removing contaminants,
and producing high-quality effluent suitable for various applications.
• Sequencing Batch Reactors (SBR)
A batch process for wastewater treatment, combining biological treatment stages in a single
reactor, offering flexibility and efficiency.
7. Advanced Treatment
Technologies Overview
• Chemical Treatment
Employing chemicals to alter properties of water/wastewater, including
disinfection, pH adjustment, and precipitation, crucial in achieving desired
treatment outcomes.
• Advanced Oxidation Processes (AOPs)
Employing chemicals to alter properties of water/wastewater, including
disinfection, pH adjustment, and precipitation, crucial in achieving desired
treatment outcomes.
• Coagulation/Flocculation
Aggregation of particles through chemical agents (coagulants) followed by
gentle mixing (flocculation), aiding in the removal of suspended solids
from water.
8. Technical Comparison
• Membrane Bioreactor (MBR):
• - Utilizes a combination of biological treatment and membrane filtration.
• - Features submerged membranes which act as physical barriers to separate solids from the
treated water.
• - Operates continuously with a constant flow of influent and effluent.
• - Requires a relatively smaller footprint compared to conventional treatment systems due to
higher treatment efficiency.
• - Offers excellent effluent quality with low turbidity and suspended solids concentration.
• - Typically higher initial investment costs due to membrane installation and maintenance.
• - Prone to fouling of membranes, necessitating regular cleaning and replacement.
• - Suitable for large-scale applications where space is limited and stringent effluent quality
standards must be met.
9. • Sequential Batch Reactor (SBR):
• - Operates in batch cycles, including fill, react, settle, and decant phases.
• - Utilizes a single tank for multiple treatment processes, including biological degradation, settling,
and decanting.
• - Offers flexibility in operation and can accommodate fluctuations in influent flow and
composition.
• - Generally requires a larger footprint compared to MBR due to the need for multiple tanks and
settling periods.
• - Provides good removal efficiency for organic matter and nutrients.
• - Effluent quality can vary depending on the operational parameters and settling characteristics.
• - Lower initial investment costs compared to MBR, but operational costs may be higher due to
periodic maintenance and monitoring requirements.
• - Suitable for small to medium-sized treatment plants where space is not a significant constraint
and operational flexibility is desired.
10. • Comparison:
• - Treatment Efficiency: MBR generally provides higher effluent quality with lower turbidity and
suspended solids compared to SBR.
• - Footprint: MBR typically requires a smaller footprint due to its continuous operation and
compact design, while SBR may need more space due to batch processing and multiple tanks.
• - Flexibility: SBR offers operational flexibility to handle fluctuating influent conditions, while MBR
operates clower compared to SBR in the long term.
• - Maintenance: MBR requires regular membrane cleaning and replacement to prevent fouling,
while SBR may have lower maintenance requirements but may need periodic adjustments for
optimal performance.
• - Suitability: MBR is suitable for large-scale applications with stringent effluent quality
requirements and limited space, while SBR is suitable for smaller to medium-sized plants with
varying influent characteristics and space availability.
• continuously and may be less adaptable to variations.
• - Cost: Initial investment costs are usually higher for MBR due to membrane installation, but
operational costs may be
