Innovations in Water Treatment: The Legacy of Wallace & Tiernan Disinfection Equipment

In the realm of water treatment, ensuring the safety and purity of our water supply is paramount. Among the pioneers in developing cutting-edge disinfection equipment, Wallace & Tiernan has left an indelible mark on the industry. This article explores the legacy and innovations of Wallace & Tiernan disinfection equipment, which has played a crucial role in safeguarding global water sources.


A Legacy of Innovation

Founded in 1914 by Charles F. Wallace and Charles A. Tiernan, Wallace & Tiernan quickly established itself as a trailblazer in the field of water treatment. The company’s commitment to innovation led to the development of groundbreaking disinfection technologies that revolutionized water treatment practices.


Chlorination Advancements

One of the most significant contributions of Wallace & Tiernan to water treatment is in the field of chlorination. The company pioneered the development of gas chlorinators, devices that efficiently introduce chlorine gas into water for disinfection purposes. This innovation marked a departure from earlier, less precise methods of chlorination, allowing for more controlled and effective water treatment processes.


Gas Chlorination Systems

Wallace & Tiernan’s gas chlorination systems became synonymous with reliability and precision in water disinfection. These systems allowed water treatment facilities to maintain optimal chlorine levels, ensuring the elimination of harmful microorganisms without compromising water quality. The ability to precisely control the dosage of chlorine gas revolutionized the disinfection process, contributing to the improved safety and efficacy of water treatment.


On-Site Hypochlorite Generation

In addition to gas chlorination, Wallace & Tiernan played a pivotal role in advancing on-site hypochlorite generation technology. This innovation allowed water treatment plants to produce sodium hypochlorite (bleach) on-site, eliminating the need for the transportation and storage of hazardous chlorine gas or commercial bleach. On-site generation provided greater control over disinfection processes and improved safety for operators.


Modern Analytical Instruments

As water treatment technologies evolved, so did the need for precise monitoring and control. Wallace & Tiernan responded to this demand with the development of modern analytical instruments. These instruments, equipped with advanced sensors and monitoring capabilities, allow water treatment professionals to continuously assess water quality, ensuring compliance with regulatory standards and maintaining the effectiveness of disinfection processes.


Legacy of Safety and Reliability

Wallace & Tiernan’s commitment to safety has been a defining aspect of its disinfection equipment. By providing water treatment professionals with tools that enhance precision, control, and safety, the company has contributed to the reduction of health risks associated with waterborne contaminants. The legacy of Wallace & Tiernan disinfection equipment is a testament to its enduring impact on public health and the safety of water supplies.


Global Reach and Ongoing Innovation

Through the years, Wallace & Tiernan’s disinfection equipment has achieved a global presence, with installations in water treatment facilities around the world. The company’s commitment to ongoing innovation ensures that its solutions remain at the forefront of water treatment technology, adapting to emerging challenges and contributing to the sustainability of water resources.



Wallace & Tiernan’s contributions to water treatment, particularly in the realm of disinfection equipment, have left an indelible mark on the industry. From pioneering gas chlorination to advancing on-site hypochlorite generation and modern analytical instruments, the company’s legacy is one of innovation, safety, and reliability. As communities worldwide continue to prioritize access to safe and clean water, the innovations introduced by Wallace & Tiernan continue to play a vital role in shaping the future of water treatment.
