Sumitomo Electric Wins Record-Breaking Water Treatment Membrane Order for Indonesian Sewage Plant

The Republic of Indonesia has the world's fourth-largest population (approximately 270 million people), and while the economy continues to grow, the capital’s Jakarta Special Region, with a population of over 10 million, has a low sewage system coverage rate, which is causing serious water quality problems. To address the problems, the Jakarta Sewage Management Master Plan has been formulated, dividing the sewage treatment districts into 15 zones and promotes the development of sewage systems in stages.

In particular, in the first construction zone, which has a high population density and many commercial facilities, a sewage treatment plant is required, capable of treating a water volume of 240,000m3/day (planned population: 1.24 million) under severe site constraints. For this reason, the Membrane Bioreactor (MBR)* was selected as the sewage treatment process because it saves space and achieves high treatment performance. We have received an order for PTFE POREFLON™ hollow fiber membrane modules as equipment for MBR.

* Membrane Bioreactor (MBR) One of the "activated sludge methods" that are effective in purifying sewage and industrial wastewater. This method uses a filtration membrane to separate the treated water, in which microorganisms (activated sludge) have decomposed the organic matter contained in the wastewater, from the fine particles present in the wastewater and the microorganisms themselves.
