ORGANICA MM2100 WWTP Bekasi Fajar, INDONESIA Detailed Case Study
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 2
Project Background Project Population Served Project Type Municipal WWTP; design, build 200 000 equivalent Greenfield Contract Award March 2013 Hydraulic capacity 45 000 m 3 /day Design Completion October 2013 Construction Begins January 2014 Expected Commissioning September 2015 3

Original Situation One of the leading industrial parks in the country with high-profile multinational tenant/resident companies Need for expanding WWTP capacity to 45 MLD which required additional land Existing, traditional 27 MLD Activated Sludge WWTP occupying prime real estate in the industrial park (1.6 hectare site) Existing WWTP - large, unsightly, and emits bad odors thus any neighboring tenants negatively impacted. Huge buffer zone (which is not available) required around WWTP due to odors and negative aesthetics 5
Demand Drivers 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 (by approximately 30%) to avoid disposal issues 6
Demand Drivers WWTP Options Existing Plant (Conventional Approach) Ultimate Capacity Required (Conventional) Organica Solution (under construction) Capacity (MLD) 27 2.0 Land Occupied/ Required (in Hectares) 45 4.0 4.5 * 45 1.5 ** Additional Benefits No need for buffer zone due to odorless and aesthically appealing installation Lower energy consumption resulting in significantly lower operational costs, higher profit by maintaining the same tariff Client recovers complete investment in Organica facility by selling land occupied by existing plant * Land Available for additional capacity Only 2.0 Hectares ** Land Savings obtained by client by choosing Organica 2.5 hectares 7
Organica Solution 67% higher capacity in 30% lower footprint 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 sludge generation 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 wastewater treatment Land utilized by existing plant made available for sale/lease (offsets costs of new plant) 8

Paradigm Shift The Paradigm Shift 10
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. 11 11
