Waste water treatment  [ Return towards  Our offer  ]

We know you are focused on your production processes. But we also know you are committed to responsible care of the environment and to comply with your local legislation. Air Liquide can help you to find the best solutions in the field of waste water treatment.

Injecting carbon dioxide is an easy, cost-effective and very safe way to control pH in your effluent. Whenever alkalinity is too high, a simple injection of CO₂ will take you to the neutral zone while avoiding over-acidity. Moreover, CO₂ is much less troublesome to handle than most chemicals!

The use of oxygen in a biological basin not only greatly enhances the efficiency of your water treatment unit but also increases the settlability of the sludge, radically cuts your energy consumption, and substantially reduces foul-smelling substances.

Key to our contribution to your success is our extensive experience gained over more than 20 years in many countries, and in most industries.

We have also developed state-of-the-art gas/liquid transfer systems, which allow you to minimize your de-pollution costs:

• VENTOXAL™
  is our 500-times referenced oxygen transfer device. Oxygen flows of up to 240 kg/hr can be injected through a single unit to deliver maximum yield!          

• TURBOXAL™
  has been specifically developed for shallow basins (less than 4 meters deep), where a floating device optimizes the oxygen bubble plume in such a way that O₂ will be optimally dissolved in water.

Whenever your waste stream needs discoloration of hard COD abatement, think about ozone! Air Liquide has the ozone production capabilities as well as application technologies for water purification and waste water treatment. We also know how to couple between ozone injection, oxygen-rich off gas recovery and its re-use in a biological basin. This enables you to benefit from a fully integrated solution.

At Air Liquide, we keep working on wastewater treatment in a broad range of new technology development projects. Our experts will find a solution to any problem you may encounter.
