ABB has won a $30 million contract to automate Singapore’s Tuas Water Reclamation Plant, the world’s largest membrane bioreactor.
Run by PUB – Singapore’s National Water Agency, the Tuas WRP has a treatment capacity of 800,000m³ per day, enough to fill over 300 Olympic-size swimming pools.
The plant is integral to Singapore’s growing population of 5.69 million. The island nation is considered to be one of the most water-stressed countries in the world with no natural water sources.
With a 30% more compact footprint than conventional plants, the Tuas WRP is a key component of the second phase of Singapore’s $4.8 billion Deep Tunnel Sewerage System (DTSS).
Tuas WRP will receive used water flows from the western part of Singapore via two separate deep tunnels and apply its Membrane Bioreactor (MBR) technology to treat and purify 650,000m3/day of domestic used water to generate NEWater.
NEWater is a high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, making it ultra-clean and safe to drink.
ABB’s role in this endeavor will be to deliver a complete site-wide plant monitoring and control system for the Tuas Water Reclamation Plant (WRP).
Leveraging its ABB Ability 800xA control platform and Supervisory Control and Data Acquisition (SCADA), ABB will deploy process control systems across multiple facilities at the site.
The overall system will integrate over 100,000 input/output signals from different assets including pumping stations, a wet weather facility, biosolids, domestic liquid and industrial liquid modules and product water storage, into one unified control platform, providing complete visibility of operations across the plant network.
ABB has announced that it will also deliver advanced process control solutions to improve plant performance and efficiency. It will allow operators to monitor ventilation and air conditioning systems and, critically, manage energy utilization across the site.
Alarm monitoring and security systems will be further deployed to help ensure industrial control, including cyber security solutions that assess threats and test vulnerability, meeting Singapore’s stringent cyber security requirements.
