First, let’s understand the basics of turbidity. 1. Introduction to turbidity Natural water and wastewater contain a variety of insoluble substances of different particle sizes, such as soil, fine sand, organic matter and microorganisms, which can cause turbidity. The degree of turbidity of the water sample can be expressed by the magnitude of the turbidity. …

Ammonia nitrogen refers to the nitrogen in ammonia or ammonium state in water, which is one of the important indicators of eutrophication and pollution of water bodies. There are many methods for the determination of ammonia nitrogen, and this article will introduce five commonly used methods, namely Nessler’s reagent spectrophotometry, salicylic acid-hypochlorite spectrophotometry, distillation-neutralization titration, …

According to the “Hygienic Standard for Drinking Water” (GB5749-2006), the residual chlorine content of the factory water is ≥ 0.3mg/L, and the residual chlorine concentration of the water at the end of the pipe network is ≥0.05mg/L, which is not harmful to the human body. Although the residual chlorine of the latter still has the …

What are the residual chlorine test methods? What are the pros and cons of each? Read More »

In the case of continuous use, on-line residual chlorine analysis will inevitably encounter zero drift, system contamination, and interference factors caused by changes in sample flow rate, pH, temperature, etc., especially the residual chlorine concentration at the end of the pipe network is very low, and the residual chlorine content in the water is only …

We can easily think about the oxygen in the air that we inhale; however, liquids around us also have oxygen. It is not that humans are the only organism that requires oxygen to lead a life. The use of oxygen is of utmost importance in the preservation of food, water management, and monitoring of the …
