�� Developed with the main aim to overcome Developed with the main aim to overcome problems associated with problems associated with ASP,SBR,MBR &ASP,SBR,MBR &FABBRFABBR technologies such as filter technologies such as filter clogging,wash out of microbes clogging,wash out of microbes

�� MAR is a Hybrid reactor utilising the MAR is a Hybrid reactor utilising the specially cultured microbes resulting in specially cultured microbes resulting in active microbial bio mass forming very active microbial bio mass forming very dense granules which are highly settable.dense granules which are highly settable.

What is “MAR” What is “MAR” -- ContdContd

�� As a result Very high Concentration of As a result Very high Concentration of active biomass could be achieved per unit active biomass could be achieved per unit working volume of reactor resulting in working volume of reactor resulting in reduced space and lesser blower air reduced space and lesser blower air requirements (lesser electrical energy)requirements (lesser electrical energy)requirements (lesser electrical energy)requirements (lesser electrical energy)

�� Hence this reactor is operable with high Hence this reactor is operable with high loading rates and excellent BOD, COD loading rates and excellent BOD, COD removal with lesser HRT(hydraulic removal with lesser HRT(hydraulic retention time) retention time)

Advantages of “MAR” over “MBR”Advantages of “MAR” over “MBR”

�� MAR uses specially cultured microbesMAR uses specially cultured microbes1.1. High concentration of Bio mass achieved per unit High concentration of Bio mass achieved per unit

working volume of reactor working volume of reactor –– Results in 25% lesser Results in 25% lesser space requirementsspace requirements

2.2. High loading rates with lesser Holding Retention Time High loading rates with lesser Holding Retention Time (HRT) due to active microbiological process (HRT) due to active microbiological process ––Lesser Lesser (HRT) due to active microbiological process (HRT) due to active microbiological process ––Lesser Lesser compressed air requirements per unit volume compressed air requirements per unit volume -- Results Results in 30% power savingsin 30% power savings

3.3. Fully a microbiological activity and does not involve any Fully a microbiological activity and does not involve any mechanical separations such as membranes in MBR mechanical separations such as membranes in MBR ––Results in lesser maintenance costs involved in Results in lesser maintenance costs involved in replacement of membranes replacement of membranes

4.4. Due to active Due to active digestorsdigestors very very densedense granules are granules are formed which is highly formed which is highly settlablesettlable –– Results in very less Results in very less sludge formation and is easy to handlesludge formation and is easy to handle
