COMPARISION AMONG ASP, MBBR, SBR AND MBR

 

COMPARISION AMONG ASP, MBBR, SBR AND MBR 

 

Technology

ASP

MBBR

SBR

 MBR

Aeration Unit

Needs a Big Aeration Tank with surface aerators or diffused aeration.

Floating media is used providing a surface for microbial growth

Operates in batch where waste water is added to the reactor, treated and discharges.

Normal biological treatment like MBBR

Settling Unit

Uses a Common circular Settling Tank

A tube settler is used for high sludge removal rate.

NIL

Membrane filtration process in place of Settler.

Efficiency

Average Efficiency

High Treatment efficiency. Robust against fluctuation flow and load

Flexibility in Treatment. High Nutrient removal

Superior effluent quality due to membrane barrier.

Area

Largest Area

Most compact system

Requires less area than ASP

50% less area then SBR

Uses

Used in Municipal waste water treatment plant

Used in Decentralized waste water treatment plant and Industries.

Suitable for smaller STP. It has some constraints in Municipal waste water treatment plant

Used in Decentralized waste water treatment plant and Industries, especially when plant is to be designed for zero discharge.

Cost

Medium Cost

EASY TO MAINTAIN

Lowest capital and maintenance cost, EASY TO MAINTAIN

High maintenance cost

High Energy Load, Maintenance cost 20% lower than SBR
