Exchange 106, Kuala Lumpur, Malaysia
ASEAN Tallest Building, Exchange 106 in Malaysia Chooses Supratec MicroClear® MBR to Meet Green Building (GBI) Gold Certification
Challenge
The Exchange 106 is the tallest building in Malaysia as well as South East Asian Nations (ASEAN), with a height of 492 metres. With a height equivalence of 112 floors, this modern icon nestled within the prestige Tun Razak Exchange (TRX) area, comprises 106 floors of expansive column-free floorplates inclusive of 8 amenity floors and 6 basements. The tower have a net lettable area of 240,000 square metres and is benchmarked against similar buildings in large international financial centers, such as London’s Canary Wharf and The Shard, New York’s Freedom Tower, and Shanghai IFC.
Designed to the highest specifications it is environmentally sustainable and certified under the Green Building Index (GBI) Gold Certification as well as the Leadership in Energy and Environmental Design. Water reuse is one of the key criteria to help the tower Owner meeting GBI Gold Certification. As such, the project proponent decided to choose MBR technology coupled with RO for water reuse in its own tower cooling system as well as make up water for toilet flushing and irrigation.
Solution
OCNED Sdn Bhd won the competitive bid for the construction of the MBR system in the tower basement, utilising MicroClear® MBR technology. Ultimate design capacity for the MicroClear® MBR system is 1,500 m3/d, with a current design capacity of 1,000 m3/d, with domestic wastewater constituents only.
The treatment train consists of odour removal, coarse screen, grit removal, oil and grease removal, 2mm rotary fine screen, EQ, anoxic, aerobic, MBR trains and aerobic sludge digester. All major equipment and biological process tanks, except the MBR, are designed for the ultimate design capacity of 1,500 m3d. There are two (2) MBR trains, with each train populates to handle current design capacity of 1,000 m3/d, with an allowance for additional membrane modules installed for the ultimate design capacity of 1,500 m3/d. MBR effluent is being sent to an effluent storage tank where it will be pumped to a RO system for final treatment before reuse.
Results
The Exchange 106 manages to meet GBI Gold Certification with water reuse feature using Supratec MicroClear® MBR technology and RO technology.
