With our Inquiry about water we had a visit from Katherine from Water Care again today talking about water use and filtering water. It is amazing to think that individuals use 170 litres of water per day and only 2-3 litres of that is what we are required to drink.
The water was yucky, and we had mixed results for the filtering systems. From the systems I have seem before the water passes through the course objects first like bark and then sand, as you don’t want the dirt or sand going throught hole into the water tank. Then it should go through the cotton balls and then the paper last. We learnt that the harder the filter is packed the slower the water will run through.
