MBBR — Moving Bed Bio-Reactor

A compact, low-power alternative to conventional activated sludge treatment

MBBR (Moving Bed Bio-Reactor) technology is a better alternative to conventional wastewater treatment plants that are large-sized, power intensive and require constant monitoring. It offers an effective option where space and power are scarce.

Sewage passes through an equalization tank into the MBBR reactor, where free-moving biofilm carriers under constant aeration host the bacteria that break down organic load. A tube settler / clarifier separates treated water from biomass before it moves to tertiary treatment.

Supplied from 10 KLD to 2 MLD and above.

Advantages

Advantages of MBBR

  • Odourless operation with a self-regulating system.
  • High biofilm surface area — compact plants with high loading rates.
  • Reduced power consumption compared with conventional activated sludge.
  • Simple to operate, with low maintenance requirements.
  • Non-clogging design and better oxygen transfer efficiency.
  • Attached growth process — no sludge recycling, high MLSS maintained.
  • Easy to monitor; removes E. coli and coliform.
  • Capacity from 10 KLD to 2 MLD and above, in prefabricated or civil construction.
  • Recycling for gardening, flushing, car wash and cooling towers.
  • Tertiary PSF, ACF and optional UF for consistent CPCB reuse quality.
