What is water solid?

All impurities in water are called solids except dissolved gases. Solids in water can be divided into dissolved solids and suspended solids. The sum of the two is called the total solid content of water. Dissolved solids refer to various inorganic salts, organic substances, etc. Still dissolved in water after filtration. Suspended solids refer to suspended substances such as mud, sand, clay, organic matter and microorganisms that are insoluble in water. The total solid content was determined by evaporating water and weighing. Therefore, the evaporation temperature has a great relationship, and it is generally controlled at 105~ 1 10℃.
