News Releases 2021Meiden Singapore to supply ceramic membranes for world’s largest ceramic membrane bioreactor project to treat industrial used water at Singapore’s Tuas Water Reclamation Plant

Meiden Singapore Pte. Ltd. (Meiden Singapore), a subsidiary of Meidensha Corporation (President: Takeshi Miida, Meiden) has clinched a contract from Koh Brothers Building & Civil Engineering Contractor (Pte.) Ltd. to supply and implement its patented ceramic membranes at the Tuas Water Reclamation Plant (WRP). In October 2021, Koh Brothers was appointed by PUB, Singapore’s national water agency to install the mechanical, electrical, instrumentation, controls and automation (MEICA) equipment for the first of Tuas WRP’s two Industrial Liquids Modules (ILM1), which will house the world’s largest ceramic membrane bioreactor (MBR) facility when completed.
Meiden’s ceramic membranes, which are highly durable, more resistant to chemical damage and have a longer life span, also contribute to greater energy savings. The membranes will have a treatment capacity of 97,500m3 per day.

Meiden has also been working with PUB to conduct a feasibility study, using ceramic MBR technology to treat industrial used water at a demonstration plant located in the existing Jurong WRP. This partnership is based on a Memorandum of Understanding (MOU) signed with PUB in 2010 for the joint development of water treatment technology. The plant (treatment capacity: 4,550m3/d) has been in operation since 2014 and proved that ceramic MBR can treat high-strength industrial used water for reuse.

Meiden Singapore’s core base is in Southeast Asia and Middle East. Through its work with PUB, Meiden continues to make every effort to contribute to ensuring a resilient water supply for Singapore, as well as cementing the country’s status as a global hydrohub.

Moreover, through its manufacturing initiatives, Meiden is committed towards achieving a more sustainable future. Meiden makes utmost effort to realize sustainable value creation and resolve a variety of social issues, including meeting the UN’s Sustainable Development Goals (SDGs) such as “Clean water and sanitation” and “Life below water”.

Ceramic flat-sheet membrane

— The ceramic flat-sheet membrane has a myriad of fine holes (pores) that cannot be seen by the naked eye. When used water passes through the holes, impurities are filtered out, producing clean water.
— The 6-millimeter-thick ceramic flat-sheet membrane has a hollow structure; filtered clean water is gathered via water-collecting channels and transported out of the membrane.
