Top 10 Dissolved Oxygen Suppliers in China
Nov 19, 2025| Introduction to Dissolved Oxygen
Dissolved oxygen (DO) refers to the amount of oxygen that is present in water. It is a crucial parameter in various fields, especially in environmental monitoring, aquaculture, and wastewater treatment. In environmental monitoring, DO levels are used to assess the health of water bodies such as rivers, lakes, and oceans. Adequate DO is essential for the survival of aquatic organisms, as they rely on it for respiration. In aquaculture, maintaining appropriate DO levels is vital for the growth and well - being of fish, shrimp, and other aquatic species. In wastewater treatment, DO is used to support the growth of aerobic bacteria that break down organic matter.
