A Nostalgic Moment

In a box attached to our dressing table lot of miscellaneous things were kept away.Recently,I found from them two Important items of personal importance which i thought I had lost.looking at them brought a flood of memories.

The card shows that I attended a session of UN General Assembly as a member of Indian delegation in 1975.Not everybody is fortunate to get a chance to attend such a prestigious meeting. At that time i was serving in the External Affairs Ministry ,New Delhi.

The other photo exhibits a medal of excellence. It is the prestigious Pratibha Davi medal awarded to me by the Gauhati University (it was then the only university in the entire state of Assam)for securing the highest marks in B A Hons exam of1960 in the entire university.

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
