Reverse Osmosis is the mechanism whereby water is pressurised through a membrane to exclude contaminants. 

Originally developed by the U.S. Navy to remove the "salt" from salt water so that the missions on which warships were sent could exceed the amount of fresh water that could be carried. 

Hydrogen sulphide is a gas which readily dissolves in water. When released by say turning on tap the disolved gas escapes from the water to become a gas again.  

The first indication of the presence of Hydrogen sulphide is the noxious odour. In most cases Hydrogen sulphide or the “Rotten Egg” smell will be greatly depleted, or even absent by the time the sample arrives at the lab. For this reason it can be quite difficult to quantify the problem. 

If you have any issue with your water, the best place to start is with a water treatment professional.

When we say that we mean someone who has invested in achieving true water treatment credentials.
