Key points for water quality testing operations in sewage treatment plants part two
13.What are the precautions for measuring CODCr? CODCr measurement uses potassium dichromate as the oxidant, silver sulfate as the catalyst under acidic conditions, boiling and refluxing for 2 hours, and then converts it into oxygen consumption (GB11914–89) by measuring the consumption of p...Read more -
Key points for water quality testing operations in sewage treatment part one
1. What are the main physical characteristics indicators of wastewater? ⑴Temperature: The temperature of wastewater has a great influence on the wastewater treatment process. The temperature directly affects the activity of microorganisms. Generally, the water temperature in urban sewage treatmen...Read more -
The practicality of wastewater detection
Water is the material basis for the survival of Earth biology. Water resources are the primary conditions for maintaining the sustainable development of the earth’s ecological environment. Therefore, protecting water resources is the greatest and most sacred responsibility of human beings....Read more -
Definition of Turbidity
Turbidity is an optical effect that results from the interaction of light with suspended particles in a solution, most commonly water. Suspended particles, such as sediment, clay, algae, organic matter, and other microbial organisms, scatter light passing through the water sample. The scattering ...Read more -
Total Phosphorus (TP) Detection in Water
Total phosphorus is an important water quality indicator, which has a great impact on the ecological environment of water bodies and human health. Total phosphorus is one of the nutrients necessary for the growth of plants and algae, but if the total phosphorus in the water is too high, it will ...Read more -
Simple Process Introduction of Sewage Treatment
The sewage treatment process is divided into three stages: Primary treatment: physical treatment, through mechanical treatment, such as grille, sedimentation or air flotation, to remove stones, sand and gravel, fat, grease, etc. contained in sewage. Secondary treatment: biochemical treatment, po...Read more -
Turbidity Measurement
Turbidity refers to the degree of obstruction of the solution to the passage of light, which includes the scattering of light by suspended matter and the absorption of light by solute molecules. The turbidity of water is not only related to the content of suspended substances in the water, but a...Read more -
Biochemical Oxygen Demand VS Chemical Oxygen Demand
What is Biochemical Oxygen Demand (BOD)? Biochemical Oxygen Demand (BOD) Also known as biochemical oxygen demand. It is a comprehensive index indicating the content of oxygen-demanding substances such as organic compounds in water. When the organic matter contained in the water is in contact wit...Read more -
Six treatment methods for sewage high COD
At present, the typical wastewater COD exceeds the standard mainly includes electroplating, circuit board, papermaking, pharmaceutical, textile, printing and dyeing, chemical and other wastewater, so what are the treatment methods for COD wastewater? Let’s go and see together. Wastewater CO...Read more -
What are the harms of high COD content in water to our lives?
COD is an indicator that refers to the measurement of the content of organic substances in water. The higher the COD, the more serious the pollution of the water body by organic substances. Toxic organic matter entering the water body not only harms organisms in the water body such as fish, but a...Read more -
How to quickly judge the concentration range of COD water samples?
When detecting COD, when we get an unknown water sample, how to quickly understand the approximate concentration range of the water sample? Taking the practical application of Lianhua Technology’s water quality testing instruments and reagents, knowing the approximate COD concentration of the wa...Read more -
Accurately and quickly detect the residual chlorine in water
Residual chlorine refers to that after chlorine-containing disinfectants are put into water, in addition to consuming a part of the amount of chlorine by interacting with bacteria, viruses, organic matter, and inorganic matter in the water, the remaining part of the amount of chlorine is called r...Read more
