— water purification from nitrates — salts of nitric acid. Nitrates are widely used as fertilizers; most of them are processed by plants into harmless compounds, but unused residues can enter the water, and such substances are harmful to the human body. Purification can be carried out both by reverse osmosis (see "Purpose"), and chemically — due to substances that bind nitrates and do not allow them to pass the filter.
