Activated Sludge Process – Extended aeration

Sequential Batch Reactor (SBR)

Moving Bed Bio-Reactor (MBBR)

MBBR/FBBR

• Compact and Modular MBBR/FBBR
• Being used where space is a real constraint
• Attached growth process utilizes special plastic media for retaining more biomass in the attached form.
• The units shall be either in MS or in RCC based on customer need.
• Reduced power consumption
• Low sludge production
• High organics loading is possible
• Compact Tube / Inclined plate settlers used in place of huge clarifiers.

Membrane Bio-Reactor (MBR)

• Superior Treated water quality
• Improves down stream RO performance ( longer life for RO membranes, higher flux, fewer cleaning)
• Best suited for plant capacity augmentation where space is a constraint.
• Unlike ASP it does not require clarifier, and filtration system
• Increase volumetric loading
• Easy sludge handling (Less sludge wasting due to higher Sludge age),Removal of micro nutrients possible.
