Nitric Acid – The Vital Ingredient in Industrial Water Treatment

Introduction

Nitric acid, a colorless and highly corrosive mineral acid, plays a pivotal role in various industrial applications, particularly in water treatment. Its chemical versatility and reactivity make it an essential component for wastewater management and purification processes. This article delves into the properties, uses, and safety considerations of nitric acid while highlighting its relevance in the water treatment industry.

Properties of Nitric Acid

Nitric acid (HNO₃) is characterized by its sharp, acrid odor and strong oxidizing properties. It is commonly available in concentrations ranging from 68% to 70% and can dissolve most metals, making it highly reactive.

Key Properties:

• Corrosive and oxidizing agent

Applications of Nitric Acid in Water Treatment

Nitric acid serves as a critical chemical in industrial water treatment processes, contributing to effective purification and waste management.

1. pH Control

   • Nitric acid is used to neutralize alkaline wastewater, maintaining the desired pH levels for safe discharge or reuse.

2. Metal Precipitation

   • It helps in the removal of heavy metals from wastewater by forming insoluble compounds, facilitating easier separation.

3. Cleaning and Descaling

   • Nitric acid is widely employed to clean industrial equipment, removing scale and deposits to ensure efficient operation.

4. Oxidation Processes

   • It acts as an oxidizing agent in advanced treatment processes, breaking down harmful organic compounds.

Safety and Handling of Nitric Acid

Given its corrosive nature, handling nitric acid requires strict adherence to safety protocols.

• Storage: Store in acid-resistant containers away from heat and incompatible substances.
• Protective Gear: Always use gloves, goggles, and acid-resistant clothing.
• Spill Management: Use neutralizing agents like sodium bicarbonate to safely manage spills.
