Nitrate minerals can be found in water depending on agriculture, stock raising or settlement.

Harmful elements are removed from spring water or water from its original source through soil naturally but nitrate stays in water that´ s why ratio may be too high.

Machines and installations that work with water has to be protected from water that has nitrate minerals.  They could be harmful to the devices and installations if the ratio is too high.

I order to remove nitrate minerals automatic nitrate filters are used.
