What is water quality? Water quality index? Water quality standard? Water quality refers to the comprehensive characteristics of water and water impurities. Water quality indicators refer to the standards and scales for measuring the quality of water quality. Water quality standards refer to the minimum quantity or concentration limits and requirements for impurities (specific impurities or contaminants) in water that meet certain specific requirements. What is the technical indicator of water quality? Natural water always contains a lot of impurities, which leads to the problem of good water quality. Since the water uses are different in different processes and the water quality requirements are different, the water quality indicators used in different processes are also different. This is due to technical requirements and represents the sum of certain compounds. An indicator that characterizes a certain performance of water quality is called a technical indicator. Tables 1-6 list various indicators for boiler water use in power plants, where self-suspending to stability is a technical indicator. How to determine the suspended solids content in water? The determination of suspended solids in water is a weighing value obtained by filtering a certain volume of water sample and drying the separated solid matter at 105 to 110 ° C to a constant weight, and the unit is mg/L. When measuring suspended solids, the following points should be noted: 1 Due to different filter materials, the results obtained are different, so when reporting the results of the analysis, the filter material should be indicated. 2 The volume of water sample obtained during the measurement is related to the suspended solid content in water. See Table 1-7. 3 When the suspended matter content of water is less than 25 mg/L, the difference between the total solid matter and the dissolved solid matter can be obtained. which is: Suspended solids = all solids - dissolved solids Floor Lamps
