Current water disinfection solutions problems
Traditional solutions for water treatment
especially in developing countries
just don’t fit:
Boiling
time-consuming
and not scalable
Chemical-based
(e.g. chlorine) dependent on ongoing supply, affects taste, requires a trained operator. May leave toxic by-products.
Filter-based
Micro/ultra/nano-filtration or Reverse Osmosis - require high energy and high maintenance. The RO requires an expensive infrastructure.
Mercury UV
Effective disinfection, However- have a short lifetime (10X less than LED) ; requires high energy ; toxic disposal.
