ORGANICA
MM2100 WWTP Bekasi Fajar, INDONESIA
Detailed Case Study
© 2016 Organica Water 2
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 inthe country with high-profile multi-national tenant/resident companies
• Need for expanding WWTP capacityto 45 MLD which required additionalland
• Existing, traditional 27 MLD ActivatedSludge WWTP occupying prime realestate in the industrial park (1.6hectare site)
• Existing WWTP - large, unsightly, andemits bad odors thus anyneighboring tenants negativelyimpacted.
• Huge buffer zone (which is notavailable) required around WWTPdue 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 land requirement
• Lower energy consumption (by approximately 30%) for reducing operating costs (client responsible for operating plant)
• Lower sludge generation (byapproximately 30%) to avoid disposal issues

Demand Drivers
Additional Benefits
• No need for buffer zone due toodorless and aesthicallyappealing installation
• Lower energy consumptionresulting in significantly loweroperational costs, higher profitby maintaining the same tariff
• Client recovers completeinvestment in Organica facilityby selling land occupied byexisting plant

• 67% higher capacity in 30% lowerfootprint than existing WWTP = 138%improvement in capacity/area (twice thecapacity in less space - 1.2 hectares)
• No need for buffer zone due to odorlessand aesthically appealing installation
• Lower energy consumption and sludgegeneration resulting in significantly loweroperational costs and site issues
• New plant to be built on a small piece ofland already available resulting in:
• No disruption in wastewatertreatment
• Land utilized by existing plant madeavailable for sale/lease (offsets costsof 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 organisms
become predators for the simpler organisms.
• The result is enhanced removal efficiency and resiliency, while utilizing less energy and producing less sludge.
