    ( bactericide , virucide , fungicide , sporicide ,algaecide , amoebicide    and   biofilms)

  - Huwa-San is stable for a long period of time so it has long term     effectiveness against all  types of micro organisms in case of post     contamination

3. Why is Huwa-San environmentally friendly?

Simple composition (H2O2 + Ag+)

H2O2 is completely biodegradable to H2O+O2

The silver content in Huwa-San is only 5% of the permissible limit by countries worldwide for drinking and hence has no effect on human health.

Non corrosive for all types of surfaces in the recommended concentrations.

Non toxic

Not harmful even on long term use

4. Why do we need to disinfect when the water is already clean?

Disinfection is different from cleaning

a. Cleaning: The activity of making things clean, in a domestic or commercial environment

5. What is the effect of Huwa-San on the bacterial culture in fermented milk industry     (Yoghurt) & Vaccines in poultry farms?

The recommended concentration of Huwa-San, will effectively kill all germs from the media, and thereafter the bacterial culture will grow assuring that no germ will affect the bacterial culture or the vaccines.

The bacterial culture and the vaccines can be affected by chemical hazards from any other chemical disinfectant but not by Huwa-San due to it’s natural, non toxic, environmentally friendly components.

6. There are a lot of hydrogen peroxide products in the market, why Huwa-San?
