Farm dam water filter – the results are in!

On our farm we require good quality water for jobs like cleaning in the dairy. We built a water filter that would be capable of treating a large volume of dam water so that it could be used to top up our rain water tank through dry periods.

For a discussion of alkalinity and hardness please see Water test interpretations. Lime softening… Continue reading Reducing water hardness by lime softening

Reverse osmosis filters work by pushing water against a very fine membrane. Only a proportion of the water, usually 1/4 to 1/3 gets through, leaving behind most salts… Continue reading Boosted reverse osmosis filter for farms
