The global demand for clean and safe water is increasing rapidly, fueled by population growth, urbanization, and climate change. This necessitates a shift towards sustainable water management practices, and ozone technology is playing an increasingly significant role.
Ozone: A Powerful Tool for Sustainable Water Treatment
Ozone (O3) is a highly effective oxidant that can be used for a variety of water treatment applications, including:
Emery-Trailigaz: A Pioneer in Ozone Technology
Emery-Trailigaz, a leading supplier of ozone equipment, has been at the forefront of this technological revolution. The company's expertise lies in developing and delivering cutting-edge ozone systems tailored to specific water treatment needs.
Praxair-Trailigaz: Expanding Ozone's Reach
Recognizing the transformative potential of ozone technology, Praxair, a global leader in industrial gases and related services, acquired Emery-Trailigaz in 2008. This strategic acquisition created Praxair-Trailigaz Ozone Co., a powerhouse in the ozone industry.
The Benefits of the Acquisition:
Conclusion:
The acquisition of Emery-Trailigaz by Praxair has significantly boosted the adoption of ozone technology in sustainable water management. Praxair-Trailigaz Ozone Co. continues to be a driving force in the industry, developing innovative solutions and pushing the boundaries of ozone technology to meet the growing demand for clean and safe water worldwide.

Scenario: You are a water treatment plant manager responsible for choosing a disinfection method for your facility. You are considering using either chlorine or ozone.
Task:
This exercise requires individual research and analysis, so there is no single "correct" answer. However, a strong answer would include a clear comparison of chlorine and ozone disinfection, addressing factors like: * **Effectiveness:** Both chlorine and ozone are effective disinfectants but differ in their effectiveness against specific microorganisms and their residual effect. * **Cost:** Ozone systems are typically more expensive to install and operate than chlorine systems. * **Environmental Impact:** Chlorine has a higher environmental impact due to the formation of disinfection byproducts (DBPs). Ozone breaks down quickly in water, leaving fewer byproducts. * **Byproducts:** Chlorine produces DBPs, some of which are considered harmful. Ozone produces fewer byproducts, but the formation of bromate is a potential concern. The report should then explain the decision based on the specific needs of the water treatment facility, taking into account factors like water quality, budget constraints, and environmental regulations.
