TECHNOLOGY OVERVIEW

In light of the increasing global population, growing demand for food security, outbreak of COVID-19, as well as on-going government initiatives for better water and wastewater treatment, the global UV disinfection equipment market size is projected to reach approximately S$14 billion by 2027, at a CAGR of over 14%. However, the current UV disinfection systems suffer from multiple constraints due to the ineffectiveness and inefficiencies of existing systems. Hence, there is a need for a more robust and efficient UV disinfection system to address these existing issues.

This technology offer is a dual wavelength UV LED disinfection system. By supplementing the traditional UVC with UVA (makes microbes more susceptible to UVC), the disinfection spectrum is broadened and the overall effectiveness of the system can be improved by up to 50%. This further translates into higher energy efficiency and longer life span of the UV system. Furthermore, this technology is modular which allows for easier maintenance and lower cost of ownership compared to existing products in the market. Lastly, the bulbs in this UV system are mercury-free which reduce personnel and product safety.

The technology owner is looking for partners and collaborators in the disinfection, water treatment, and aquaculture industries to do pilot studies and further co-develop this technology.

TECHNOLOGY FEATURES & SPECIFICATIONS

This technology offer is a dual wavelength UV LED disinfection system. The features and specifications of the technology are as follows:

  • Patented dual wavelength UV (UVA and UVC)
  • Broader disinfection spectrum (Kills bacteria/parasites/viruses e.g., Vibrio alginolyticus, Escherichia coli, MS2 etc.)
  • Higher disinfection efficiency (99.5-99.99% removal)
  • Modular (Easy to use, maintain, and replace)
  • Mercury-free

POTENTIAL APPLICATIONS

The use of this technology is for industries that require disinfection treatments such as aquaculture, medical, food and beverage, baby products etc. The potential applications include (but are not limited to):

  • Water disinfection (Aquaculture industry etc.)
  • Air and surface disinfection (Different form of sterilisers such as air sterilisers, surface sterilisers, portable sterilisers, baby bottle sterilisers etc.)

Market Trends & Opportunities

The global UV devices market is sized at S$6.53 billion with a CAGR of over 14%. Comparing to current dominant products in the market, the product is able to:

  • Kill more types of microbes with higher disinfection effectiveness
  • Have much longer life span
  • Be installed and maintained easily

Unique Value Proposition

Compared to existing dominating mercury UV system, the product is mercury-free and is able to deliver:

  • 50% higher disinfection effectiveness.
  • 3 times longer life span.
  • 4 times less frequent maintenance.
  • 3 times lower cost of ownership.
