Turbidity in surface water
What is the turbidity? Turbidity refers to the degree of obstruction of a solution to the passage of light, which includes the scattering of light by suspended matter and the absorption of light by solute molecules. Turbidity is a parameter that describes the number of suspended particles in a li...Read more -
What is residual chlorine in water and how to detect it?
The concept of residual chlorine Residual chlorine is the amount of available chlorine remaining in the water after the water has been chlorinated and disinfected. This part of chlorine is added during the water treatment process to kill bacteria, microorganisms, organic matter and inorganic matt...Read more -
Summary of analysis methods for thirteen basic indicators of sewage treatment
Analysis in sewage treatment plants is a very important operation method. The analysis results are the basis for sewage regulation. Therefore, the accuracy of the analysis is very demanding. The accuracy of the analysis values must be ensured to ensure that the normal operation of the system is c...Read more -
BOD5 analyzer introduction and the dangers of high BOD
The BOD meter is an instrument used to detect organic pollution in water bodies. BOD meters use the amount of oxygen consumed by organisms to break down organic matter to assess water quality. The principle of the BOD meter is based on the process of decomposing organic pollutants in water by bac...Read more -
Overview of various commonly used water treatment agents
The Yancheng water crisis following the blue-green algae outbreak in Taihu Lake has once again sounded the alarm for environmental protection. At present, the cause of the pollution has been initially identified. Small chemical plants are scattered around the water sources on which 300,000 citiz...Read more -
