Facts about water quality
Poor water quality raises your operating cost through accelerated wear on components, which results in an increase frequency of maintenance. There are two important factors when monitoring water quality: suspended solids and total dissolved solids.
Suspended solids refer to small solid particles which remain suspended in water. Removal of these solids is generally achieved through use of filtration found on most waterjets.
TDS (total dissolved solids)
Total dissolved solids (TDS) refers to sub-molecular particles or ions found in solution in water. TDS can include hard elements like iron, silica, and calcium that can precipitate out of the water as scale on the inside of high-pressure plumbing. This scale can break off the inner walls and damage downstream valve components and orifices.
||TDS < 50 ppm
||Must be brought up to the acceptable range of between 50 and 250 ppm (usually done via mixing)
||50 ppm < TDS< 150 ppm
||Contact local specialist
||150 ppm < TDS < 250 ppm
||Soften or TDS removal
||Specialist or RO system
||TDS > 250 ppm
Silica > 15 ppm
||Soften & RO system
Moderate amounts of TDS are controlled by using water softening. Softeners remove the hard ions that can scale and replace them with soft ions, usually salt, that stay in solution.
High levels of TDS are addressed first by softening and then with reverse osmosis(RO). RO removes the hard ions and lowers the TDS to acceptable levels.
