Plaza Indonesia Shopping Mall - Jakarta, Indonesia

Black Water Treatment
MBR Ultrafiltration
Treated Water used for Roof Garden Irrigation & Cooling Tower Make up

Site Description

Plaza Indonesia is located in the centre of Jakartas’ central business district.
Since its expansion in 2008, the mall now provides around 70,000m² of retail area over 4 levels. There are over 250 retail units, food outlets and other typical retail mall services. The site also includes the Grand Hyatt Jakarta, which provides 450 hotel rooms and suites, 7 on-site restaurants & bars, 14 conference/meeting spaces.
This project presented some unique challenges for the HUBER team. The new wastewater treatment system had to be installed into the basement of the mall to replace the previous system. Hence access for the machinery was severely limited.

Huber Water Recycling System

HUBER designed, supplied, installed and commissioned a 2,200 m³/day Membrane Bioreactor (MBR) ultrafiltration system to treat the combined black and grey wastewater. This is compared to the 1,000 m³/d capacity of the original plant, which utilised the same space! The treated water is recycled as make-up water for the air conditioning cooling towers.
