Sumitomo Electric Industries has announced that it has received an order for water treatment membrane filter modules from OWJJ joint venture led by Japan's Obayashi Corporation for construction of a sewage treatment plant in Indonesia.

 

The order for Jakarta Sewage Improvement Project is the largest ever received by the company in the water treatment business.  

 

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 sewerage 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 240,000 cu ㎥/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. 

 

Sumitomo Electric said it had received an order for PTFE Poreflon hollow fiber membrane modules as equipment for MBR.

 

"Large sewage treatment plants are required to save space and reduce energy costs during operation. To meet these needs, in 2017 we developed and introduced to the market a larger product with 1.5 times the product length of our PTFE Poreflon hollow fiber membrane module, which is made of PTFE with high strength and flexibility," said an official spokesman. 

 

"This product has been highly evaluated by customers, and the features of this product were also evaluated in this project, leading to the order," he added.-TradeArabia News Service
