We make wastewater clean
Air Liquide India is a leading global water & wastewater tech company.
What is it for?
Air Liquide provides innovative, scalable, limiting carbon footprint and most importantly sustainable solutions to address toxic hard COD, sulphides, turbidity & sludge for a variety of effluents using pure oxygen and/or ozone.
Water Treatment in India at a glance
Our excellent state of the art design-build-operate capabilities help industries comply with pollution norms. We started our Indian operations in 2012 supporting pulp & paper industries in the North and slowly penetrating into other parts of India.
Water treatment consists of several mechanical and chemical processes that aim to remove water contaminants or reduce their concentration to make water more acceptable for a desired end-use. Contaminants can be solid or dissolved and include metals and minerals, organic substances, viruses, bacteria, fungi.
Gases used for Wastewater treatment
DO enrichment Capacity enhancement COD/BOD removal Sludge reduction

Biological and activated sludge treatments
Our expert teams implement the solution on site to ensure the expected performance is met.
One label, many treatments
For drinking water
NEXELIA™ for drinking water covers gas applications and equipment used for treating potable water and ozone oxidation for disinfection.
For waste water treatment
NEXELIA™ for biological treatment relates to the use of pure oxygen to boost biological basins performance with in-house gas injectors, instead of using the traditional air blowing technology. In addition, advanced oxidation treatments with ozone can be implemented to destroy micro-pollutants and harmful chemicals.
For tertiary treatment
NEXELIA™ for Tertiary Treatment is an all-in-one gas solution, using ozone (O3) to remove pathogenic organisms or pollutants which are difficult to biodegrade like micro-pollutants (pharmaceutical and personal care product residues), surfactants, inks, etc.
Gas Control Cabinet
Regulates the concentration of a dissolved gas into a liquid.
The required sensor sends a signal to a motor valve that supplies the proper gas quantity.
Treats wastewater by injecting oxygen (O2) into deep static biological basins.
Solubilizes different gases (O2 and O3) into water at saturation limit. This technology is very efficient in process water where the gas solubility
is limited by operating conditions.
A powerful and compact floating oxygen-transfer system, the OXY INJECTOR-TURBOXAL delivers high-performance oxygenation of wastewater in biological
basins and lagoons.
A dynamic gas-injection device designed to significantly increases the mass-transfer rate to reach high oxygen dissolution, and it integrates seamlessly with all types of wastewater basins.
