Industrial wastewater and water quality testing
Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the pr...Read more -
How to choose solid, liquid, and reagent vials consumables of wastewater testing? Our advice is…
Testing water quality indicators is inseparable from the application of various consumables. Common consumable forms can be divided into three types: solid consumables, liquid consumables, and reagent vials consumables. How do we make the best choice when faced with specific needs? The following ...Read more -
Eutrophication of water bodies: the green crisis of the water world
Eutrophication of water bodies refers to the phenomenon that under the influence of human activities, nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, rivers, bays, etc. in large quantities, resulting in rapid reproduction of algae an...Read more -
Chemical oxygen demand (COD): an invisible ruler for healthy water quality
In the environment we live in, water quality safety is a vital link. However, the quality of water is not always obvious, and it hides many secrets that we cannot see directly with our naked eyes. Chemical oxygen demand (COD), as a key parameter in water quality analysis, is like an invisible rul...Read more -
Determination of turbidity in water
Water quality: Determination of turbidity (GB 13200-1991)” refers to the international standard ISO 7027-1984 “Water quality – Determination of turbidity”. This standard specifies two methods for determining turbidity in water. The first part is spectrophotometry, which is...Read more -
Methods for rapid detection of suspended solids
Suspended solids, as the name implies, are particulate matter that floats freely in water, usually between 0.1 microns and 100 microns in size. They include but are not limited to silt, clay, algae, microorganisms, high molecular organic matter, etc., forming a complex picture of the underwater m...Read more -
What problems does the COD instrument solve?
The COD instrument solves the problem of quickly and accurately measuring the chemical oxygen demand in water bodies, so as to determine the degree of organic pollution in water bodies. COD (chemical oxygen demand) is an important indicator for measuring the degree of organic pollution in water...Read more -
Application of ORP in sewage treatment
What does ORP stand for in sewage treatment? ORP stands for redox potential in sewage treatment. ORP is used to reflect the macro redox properties of all substances in aqueous solution. The higher the redox potential, the stronger the oxidizing property, and the lower the redox potential, the str...Read more -
Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen and Kjeldahl Nitrogen
Nitrogen is an important element that can exist in different forms in water and soil in nature. Today we will talk about the concepts of total nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen and Kjeldahl nitrogen. Total nitrogen (TN) is an indicator commonly used to measure the tot...Read more -
Development of BOD detection
Biochemical oxygen demand (BOD) is one of the important indicators to measure the ability of organic matter in water to be biochemically degraded by microorganisms, and is also a key indicator to evaluate the self-purification capacity of water and environmental conditions. With the acceleration ...Read more -
Development of chemical oxygen demand (COD) detection
Chemical oxygen demand is also called chemical oxygen demand (chemical oxygen demand), referred to as COD. It is the use of chemical oxidants (such as potassium permanganate) to oxidize and decompose oxidizable substances in water (such as organic matter, nitrite, ferrous salt, sulfide, etc.), an...Read more -
Determination of residual chlorine/total chlorine by DPD spectrophotometry
Chlorine disinfectant is a commonly used disinfectant and is widely used in the disinfection process of tap water, swimming pools, tableware, etc. However, chlorine-containing disinfectants will produce a variety of by-products during disinfection, so the safety of water quality after chlorinatio...Read more
