Nitric Acid

Nitric Acid (HNO₃) is a strong, highly corrosive mineral acid widely used in water treatment for pH adjustment, chemical cleaning, and regeneration of ion exchange systems. Known for its powerful oxidizing properties, it effectively dissolves scale, biofilms, and metal deposits in piping and treatment units. Its precise dosing capability and rapid reactivity make it a critical agent in industrial water purification processes. Strict safety protocols are essential due to its reactivity.HNO₃7697-37-2 (CAS Number) Chemical Formula: HNO₃ Chemical Code: 7697-37-2 (CAS Number)

pH adjustment in industrial water treatment

pH adjustment is a fundamental step in industrial water treatment, involving the increase or decrease of water’s hydrogen ion concentration to achieve desired pH levels.

Regeneration of cation exchange resins

Cation exchange resins are used in water softening and demineralization to remove positively charged ions (cations), such as calcium (Ca²⁺), magnesium (Mg²⁺), sodium (Na⁺), and iron (Fe²⁺). Over time, these resins become saturated with the exchanged ions and must be regenerated to restore their functionality.

Cleaning of RO membranes and pipelines

RO systems are widely used for water purification and desalination. Over time, membranes and pipelines become fouled or scaled by impurities, reducing water flux, increasing pressure drop, and compromising water quality.
