Excerpt from Journal of the New England Water Works Association, Vol. 15: September, 1900, to December, 1901
He states that when impure water is treated with ozone, its quality is greatly improved. The dissolved ammonia is partly converted into nitrates, iron, when present, is precipitated in the form of hydrate, and the water is sterilized.
Frolich was not a biologist or chemist, and beyond pronouncing his opinion of the germicidal action of ozone and its power to mineralize organic impurities in water, he made no attempt to establish the usefulness of the process he proposed.

Paperback. Condition: New. Print on Demand. This book explores the development of water supply sanitation during the 19th century, focusing on the role of microbiology and the rise of public health awareness. The author argues that the improvement of water supplies was not simply a matter of technological advances, but also involved social and cultural changes that led to a new understanding of the causes of disease and the importance of sanitation. The book focuses on the work of Louis Pasteur and other scientists who identified the role of microorganisms in disease, and examines how this new knowledge led to the development of water treatment methods such as filtration and chlorination. The author also discusses the challenges and controversies that arose as these new methods were adopted, and how the development of water supply sanitation became an important part of public health policy.
