How to kill bacteria with solar, more details provided?
Question:
I plan to take the water from a commercialy available waste water treatment plant, pump it into a 200 litre holding tank, gravity feed for toilet flushing in the house.
To do this safely and meet governemt rules, i need to be sure of killing bacteria. I'd like to conserve power also, so it looks like UV light is the go, I have learned that the water needs to be at least 55 celcious for these to occur.
How many light globes are needed for no more then 50 litres per hour treatment? Is 55 degrese enough? Is Polyethylene a suitable material for UV lights.
I have in mind running the water through a container exposed to this light source before the 200L storage.
Thanks for you help with this, I have been weeks on it, and 5 mins here I have made some ground.
Answer:
Considering that you eliminated; solid waste, toxic waste, and inter-reactive chemical waste, at the beginning. UV filtration is most effective when liquid is continuously circulated by exposing to UV waves. UV exposure would eliminate certain types of bacteria, however, wouldn’t be enough to total disinfection. Heating method requires 350F for at least 20 minutes.
I am not sure but good thinking dude! for all you knowyour idea could be the next big hit in town.
to kill bacteria you need to autoclave it (120ºC+), kill it with UV lights, or a host of other mechanisms including fire. PE will degrade under UV light so you'll have to change your plastic
