Project Background

• MM 2100 is one of the leading industrial park

in Indonesia

• Located at Bekasi, West Java, Indonesia

• Founded in 1989 spread over a total Area

1,350 hectares• Tenants comprising 320 companies with a total

of 135,000 employees

• Existing centralized WWTP capacity of 27 MLD

operating at 20 MLD capacity

• Unhappy tenants in the neighborhood of the

WWTP as the existing facility is emitting bad

odor

• One of the leading industrial parks in

the country with high-profile multi-national tenant/resident companies

• Need for expanding WWTP capacity

to 45 MLD which required additional

land

• Existing, traditional 27 MLD ActivatedSludge WWTP occupying prime real

estate in the industrial park (1.6

hectare site)

• Existing WWTP - large, unsightly, and

emits bad odors thus anyneighboring tenants negatively

impacted.

• Huge buffer zone (which is not

available) required around WWTP

due to odors and negative aesthetics

Demand Drivers

6

• Increase WWTP capacity

• Remove need for buffer zone by

containing odors and improving

aesthetics

•

Small footprint to minimize landrequirement

• Lower energy consumption (by

approximately 30%) for reducing

operating costs (client responsible for

operating plant)

• Lower sludge generation (by

approximately 30%) to avoid disposal

issues

Demand Drivers

Additional Benefits

• No need for buffer zone due to

odorless and aesthically

appealing installation

• Lower energy consumption

resulting in significantly loweroperational costs, higher profit

by maintaining the same tariff 

• Client recovers complete

investment in Organica facility

by selling land occupied byexisting plant

•

67% higher capacity in 30% lowerfootprint than existing WWTP = 138%

improvement in capacity/area (twice the

capacity in less space - 1.2 hectares)

• No need for buffer zone due to odorless

and aesthically appealing installation

• Lower energy consumption and sludgegeneration resulting in significantly lower

operational costs and site issues

• New plant to be built on a small piece of 

land already available resulting in:

•

No disruption in wastewatertreatment

• Land utilized by existing plant made

available for sale/lease (offsets costs

of new plant)

Series Of Food Chain Reactor Zones

•   The biological process takes place in a series of cascade reactors, with standard pretreatment at the beginning,

and phase separation (via Organica Disc Filters or Secondary Clarifiers) and final polishing at the end.

•   As water flows through from one reactor zone to the next, different ecologies will grow and adapt to the

conditions in each stage. This configuration allows the “food

 chain effect”

 to develop, as higher level organismsbecome predators for the simpler organisms.

•   The result is enhanced removal efficiency and resiliency, while utilizing less energy and producing less sludge.
