What is the most cost-efficient solution for drinking water disinfection?

Published by

As we know water disinfection (deactivation or killing of pathogenic microorganisms) is the most common issue we have to deal with these days.

What are the most adopted solutions for the water disinfection?

Does any one has any comparison for both Chemical and Physical methods?

Please share your experience, cheers.

Erich, I agree with Bruce`s ...

Erich, I agree with Bruce`s answer below, to many variables for a definitive answer. Depending on the quantity required, one of the most effective basic solutions is an SSF (slow sand filter) which is easy to construct and maintain. It combines many elements of more advanced methods such as biological treatment and can render water safe to drink.

This is an excellent question ...

This is an excellent question that can only be answered with "it depends". Every water disinfectant chemical or physical like UV, has specific effectiveness on target pathogens. Some work better on certain types of microrganisms and at certain doses. The best approach is a multiple barrier approach - use more than one type of disinfectant. Can you provide any specifics on the pathogens of concern? Also affecting efficacy is the water quality, Some chemcials will interfere with certain disinfectants. I am sorry there is no single disinfectant to solve all pathogens.

The water sterilization unit that we take to market not only sterilizes but kills, destroy and removes bacteria and viruses in the water, providing the end-user with safe, clean drinking water at very low cost, without the addition of any Chemicals or Chlorine. There are additional options available for removing Toxic metals such as Arsenic and Mercury from any water source. We have conducted various tests in South Africa through an accredited testing laboratory. Please contact me should you require more information.
