How to kill bacteria with solar energy?
Question:
Answer:
Many Ultra violet wavelengths of light are deadly to bacteria. You can purchase high intensity bulbs that are focused energy of specific wl's or you can purchase high intensity bulbs and purchase optical filters to block certain wl's and pass the ones you are looking for
To add to the previous answer. The kill zone using UV is very small in water solutions. In commercial systems, the bulbs are literally touching each other. If the water is colored, you have an additional hurdle. What it means is that you just can't dig a ditch and have the sun shine on the surface.
