Water levels explained.
TDS Levels indicate impurity levels but how does this information help with the management and filtration of water for cleaning?
0 - 100 TDS
Soft water is generally ideal for human consumption and while impurity levels are still low, use of water for cleaning can still produce streaks and spotting. TDS readings generally over 8ppm will leave residue on your surface.
Slightly Hard Water101 - 200 TDS
Slightly Soft water is generally ideal for human consumption and while impurity levels are still low the use of water for cleaning is not recommended without filtering. DI resin systems will have very limited life within this range and have high running costs. Reverse Osmosis within these levels will provide extremely low running costs.
Moderately Hard Water
201 - 300 TDS
Moderately Soft water is generally ideal for human consumption and while impurity levels are still low, use of water for cleaning requires filtration. Within this range Resverse Osmosis filtration with added pre-softeners will provide an exonomical way to produce pure water. DI resin systems within this range is not recommended due to high running costs.
Hard water while still able to be used for consumption will generally require some level of filtration prior to usage, through the use of an inline water filter. These levels are only suited to Reverse Osmosis filtration. Depending on the water quantity produced, single or multiple softeners may be required prior to filtration.
