Centralised Industrial Wastewater Park, Indonesia
Indonesia Industrial Wastewater Park Reuse 85% Effluent with Supratec MicroClear® MBR
Challenge
One industrial wastewater park in Indonesia is building a centralized wastewater treatment plant to treat wastewater from various industrial factories in the industrial zone. Due to fresh water source restriction and stringent effluent discharge standards, MBR was chosen to be the preferred technology. One of the design objectives is to reuse up to 85% MBR effluent for downstream RO treatment to generate potable water and augment fresh water supply for the factories in the industrial park.Solution
A local Contractor was engaged as the main contractor for the MBR treatment plant. Supratec MicroClear® MBR was chosen as the Ultrafiltration (UF) membrane supplier utilising flat sheet membranes for the MBR plant. Construction of the MBR plant is carried out in 2 phases, with each phase catered for 2,500 m3/d. Phase 1 was started in 2018 and completed in 2019. Phase 2 will be built in the future when the plant exceeds its capacity. The treatment process consists of two Supratec MicroClear® MBR trains with 6 x MB4-4 modules in each train, so a total of 12 x MB4-4 modules.Results
The plant was successfully built over 9-month period, making it the one of the largest industrial MBR plants in Indonesia. The plant has managed to reduce the fresh water supply to the industrial park by reusing up to 85% effluent from the MBR plant. Effluent from the plant also meets stringent effluent discharge standards set by Indonesia government, which in turn has reduced the impact on the local marine ecosystem.
