1. PRESENTATION ON MAR TYPE STP

2. WHAT IS “MAR”
“MAR”
MAR stands for Multi stage Aerobic Bio
Reactor type STP – 100% result oriented
treatment methodology
Developed with the main aim to overcome
problems associated with ASP,SBR,MBR &
FABBR technologies such as filter
clogging,wash out of microbes
MAR is a Hybrid reactor utilising the
specially cultured microbes resulting in
active microbial bio mass forming very
dense granules which are highly settable.

3. What is “MAR” - Contd
As a result Very high Concentration of
active biomass could be achieved per unit
working volume of reactor resulting in
reduced space and lesser blower air
requirements (lesser electrical energy)
Hence this reactor is operable with high
loading rates and excellent BOD, COD
removal with lesser HRT(hydraulic
retention time)

4. OBJECTIVE
“MAR” – was conceived to meet the
following requirements
Reduced space requirements
Reduced Power requirements
Easy to operate and maintain
Result oriented with water re-use possibilities
re-
Eco friendly system with Ground recharge
Reduced sludge
Eliminate the odour

5. Features of “MAR”
Odorless Operation with self Regulating
system.
Non – Clogging design, better oxygen
transfer efficiency.
Simple to operate with low maintenance.
Attached growth process – No sludge
recycle and no monitoring.
High Bio –Film surface area; compact
plant with high loading rates.
Removes E-Coli (Coli form).
E-

6. Simplicity in Erection, Operation
and Maintenance
Easy to operate and maintain under widely
fluctuating conditions
Options of both underground Civil
construction and over ground MS packaged
type
Easy to install and Dismantle in case of
packaged type
Enable easy operation – Even by
unskilled operator

7. Why New MAR type STP?
Conventional Activated Sludge Process Multi Stage aerobic Bio Reactor
Large Size Reactor size is small & compact
Suspended growth of bacteria process Attached growth of bacteria process
Close monitoring required Monitoring not required
High Maintenance & Skilled labour
Low Maintenance & Simple Operation
required
Efficiency is Maximum 65% only, Further
Treatment efficiency is >95%
treatment required
Widely popular & Old techniques Most advanced technology
Odour & Colour Removal not Guaranteed No Odour & Clear treated water

8. Advantages of “MAR” over “MBR”
MAR uses specially cultured microbes
1. High concentration of Bio mass achieved per unit
working volume of reactor – Results in 25% lesser
space requirements
2. High loading rates with lesser Holding Retention Time
(HRT) due to active microbiological process –Lesser
compressed air requirements per unit volume - Results
in 30% power savings
3. Fully a microbiological activity and does not involve any
mechanical separations such as membranes in MBR –
Results in lesser maintenance costs involved in
replacement of membranes
4. Due to active digestors very dense granules are
formed which is highly settlable – Results in very less
sludge formation and is easy to handle

11. No Disposal Problem
The MAR type STP system produces quality water.
After reuse, excess water will be recharged in earth.
