Sewage Treatment Plants

Sewage Treatment Plant - Green Connect
  • Ease of shipping and greater accessibility to remote locations
  • Easy, quick set-up requires very little assembly and takes advantage of unskilled or low skilled labour.
  • Can be ready for operation in as little as a day after delivery
  • Shipping and set-up costs are considerably less than for conventional wastewater treatment facilities
  • Operating costs are considerably lower than for other treatment systems
  • Power consumption is low
  • Low odour
  • Built-in multi-stage process takes advantage of naturally occurring microbes
  • A unique and self regulating process

Principle of Treatment

It works on the principle of Aerobic Treatment with the help of aerobic bacteria, which is most conventional and proven method throughout the world.

Treatment Steps

  • Equalization and Pre-Aeration.
  • Bio-Reaction in the Aeration tank.
  • Sedimentation.
  • Pressurized sand filter.
  • Activated carbon filter.
  • Ultra violet light.
  • Chlorine dozing.

Mixed Bed Bio Reactor [MBBR]

Designing and supplying of MBBR or FAB are basically for sewage & industrial wastewater treatment. MBBR system is an advanced high rate wastewater treatment process utilizing free-floating media which houses huge quantity of active Biomass in it. Essentially MBBR system is a hybrid reactor where attached growth and suspended growth activity takes place simultaneously. Fine Bubble diffusers are used with the MBBR media in suspension (specific gravity < water) giving a good air dispersal and low level of blockage due to growth of biological film. The technology is rugged and simple to operate and the units can be pre-assembled for rapid on-site installation.


The Mixed Bed Bio Reactor (MBBR) process works on the principle of attached growth system and uses rotating biomedia to retain an active biomass to reduce the influent BOD Levels.

Advantages over Conventional ASP

  • The MBBR system is a great improvement over Conventional Extended Aeration or Activated Sludge Plants, and provides a robust and compact unit in a fully enclosed design
  • No sludge re-circulation is required to maintain MLSS as in the case of conventional aeration system
  • Can be designed to any size to deal with larger flow and loads. Around- 10 m3 to 1000 m3/day
  • Fine bubble diffused aeration used generally reduces the energy requirements as compared to surface aerators
  • The tank does not need to be drained for access to the diffusers or media
  • MBBR system takes higher shock loads without reducing the plant performance because of large quantity of MLSS available inside the reactor
  • FAB supports low sludge generation, low Adour and low Visual impact
  • Maintenance requirements are simple
