Background/Description

Water is a key resource used in industrial manufacturing activities which generates large amounts of toxic wastewater. These wastewaters will pose a threat to the environment if not properly treated before discharging  into the water bodies. Effluents from chemicals, pharmaceuticals, and textiles with extreme pHs and solvents are difficult to treat and there is a need to adopt novel technologies to address this challenge.

Based in Singapore, the technology seeker is a medium sized enterprise operating in the environmental sector. Given the above opportunity, the technology seeker intends to partner with a technology owner to co-develop a membrane material such as polytetrafluoroethylene (PTFE) can be used for membrane processes such as membrane bioreactor (MBR), ultrafiltration (UF), nanofiltration (NF) and membrane distillation (MD). Preferably the proposed technology should be in hollow fiber form factor. The technology owner is expected to provide a suitable pH and solvent resistant membrane technology, technical expertise support, and transfer of essential know-how to the technology seeker for a pilot and eventual full-scale production in Singapore.

Depending on the collaborators’ preference and further negotiations, the modes of partnership that could be considered include R&D collaboration, technology licensing and IP acquisition. The technology seeker prefers technology owners with presence and available technical professionals in Singapore to support this pilot project. Overseas-based technology owners would be considered as well in a case-by-case basis.

Technology Specification

  1. PTFE membrane material preferred but other other possible membrane materials may include polyimide (PI), polyacrylonitrile (PAN), polybenzimidazole (PBI), polyethylsuflone (PES) and polydimethylsiloxane (PDMS).
  2. A hollow fiber membrane configuration is preferred over other form factors such as flatsheet, spiral wound and tubular
  3. Able to withstand extreme pH from 0 - 14
  4. Can withstand harsh organic solvents such as DMF, NMP & DMAc etc.
  5. Temperature resistance properties of up to 50oC.
  6. Excellent oil resistant properties 

WHAT WE ARE NOT INTERESTED IN

Conventional polymeric membranes in the market that is used for drinking or muncipal water treatment made from polyvinylidene difluoride (PVDF) or  polysulfone (PS).

Preferred Business Model

  • IP Acquisition
  • Licensing
  • R&D Collaboration
