Gases and Application Technologies for Water and Wastewater Treatment
Pure Water Knowledge - For Today's Treatment Challenges
Innovative Solutions for the Water Treatment Industry
Water
is essential for all life forms, yet access to clean, safe water is becoming
increasingly difficult in many parts of the world. All water used by humans and
industry must be treated to increasingly tight regulatory standards before it
can be safely reused or returned to the natural environment.
For decades, Linde has been working with Water Treatment plant operators and stakeholders worldwide to design and commission applications for gases such as oxygen, carbon dioxide and ozone in water and wastewater treatment processes. Our innovative and pioneering solutions help operators to cost-effectively meet challenges such as pH control, substitution of acids, permanent and seasonal capacity increases. Linde’s gas-dissolution equipment maximizes dissolution efficiency and minimize power costs.

Oxygen Instead of Air
The use of pure oxygen (O2) is more
effective than air in applications that require high capacity or high levels of
dissolved oxygen.
Neutralization and Remineralization with CO2
When
dissolved in water, carbon dioxide (CO2) forms carbonic acid. Neutralization with CO2 is often less
expensive than with other acids, and safer:
pH changes with CO2 are nearly linear at basic pH, which facilitate
precise pH control. Under atmospheric pressure, the minimum pH level achieved
with CO2 is around 6.5-7.0. Even with variable raw water characteristics, the
pH can thus be easily and precisely adjusted without the danger of
acidification.
The
application of CO2 and lime is required as the final stage after desalination
before water can be distributed in the municipal network to the consumer.
Pure Oxygen for Ozone Generation
Modern ozone applications
typically see a lower lifecycle cost when oxygen is used as the feed gas
instead of air. O2-based ozone
generation offers substantial power and capital savings compared to air.
