The industrial gas business plays a critical role in water treatment and purification, ensuring safe and clean water for municipal, industrial, and environmental applications. Industrial gases such as oxygen (O₂), carbon dioxide (CO₂), nitrogen (N₂), ozone (O₃), and chlorine (Cl₂) are widely used in disinfection, pH control, aeration, and wastewater treatment to improve water quality, remove contaminants, and support sustainable water management practices.

Aeration in Wastewater Treatment

• Oxygen is injected into biological treatment tanks to promote the growth of aerobic bacteria, which break down organic pollutants in sewage and industrial wastewater. The purpose of this process is to reduce sludge buildup, improves water quality, and enhances efficiency in municipal and industrial wastewater treatment plants.

Desalination Plant Protection

• Nitrogen is applied in Applied in reverse osmosis desalination plants to prevent biofouling and corrosion in membranes and pipelines.

pH Control in Water Treatment Plants

• CO₂ is used as a safer alternative to acids in adjusting the pH of drinking water and industrial wastewater, helping prevent scaling in pipelines.

Enhanced Algae Growth for Biofuel Production

• CO₂ is injected into algae cultivation systems, accelerating biomass production for renewable biofuels.
