I have to make a water filter only using things from the kitchen. Will burnt toast particles work the same as charcoal filters if I put it in my design? Also will rice or oregano work as a possible filtration method? Any other inputs would be greatly appreciated.
P.S. I cant use any electronics

i want to know the step by step procedure on how to determine the microbial load of a certain water sample (purified water). i want to use the membrane filtration method to do this microbial load determination. i want to know how much volume of water is allowed to pass thru the filter. is it tested undiluted? or do i need to dilute it in a buffer solution? how to compute for the colony forming units (bacteria and molds) found on the filter after the incubation period. how to report the results? what is the allowable count for purified water? can you give any reference or literature for this?
