Testing the filter

The whole family has now gone back to Oz as Samuel attended the TropAg Conference in Brisbane.
We used this opportunity to bring two water filters to Australia. I've been hoping for more than 12 months to get the ceramic filter tested for its ability to stop bacteria getting through. After a number of attempts, I decided the best way was just to do it myself. Surprisingly, there do not seem to be many laboratories set up for this sort of thing.

Setting up the water filter in the lab

Richmond Water Laboratories in Lismore were willing to have a go and they were very helpful and friendly. I had to go down town, buy a plastic container and carve a hole in it to set up the filter. They will put in some highly contaminated water (like from a sewerage system) and run it through the filter. This is referred to as testing "total coliform" - or all the bugs in the water. Then they will take a sample after it has passed through the filter and incubate on petrie dishes to see if any colonies grow. I hope it works or else I'm back to the drawing board on water filtration for Timor.
