Generally the operational definition is that the solids must be small enough to survive filtration through a sieve the size of two micrometer. Primary sources for TDS in receiving waters are agricultural and residential runoff, leaching of soil contamination and point source water pollution discharge from industrial or sewage treatment plants. The most common chemical constituents are calcium, phosphates, nitrates, sodium, potassium and chloride, which are found in nutrient runoff, general stormwater runoff and runoff from snowy climates where road deicing salts are applied. Total dissolved solids (TDS) are differentiated from total suspended solids (TSS), in that the latter cannot pass through a sieve of two micrometers and yet are indefinitely suspended in solution. The term “settleable solids” refers to material of any size that will not remain suspended or dissolved in a holding tank not subject to motion, and excludes both TDS and TSS. Settleable solids may include larger particulate matter or insoluble molecules.The two principal methods of measuring total dissolved solids are gravimetry and conductivity. Gravimetric methods are the most accurate and involve evaporating the liquid solvent to leave a residue that can subsequently be weighed with a precision analytical balance (normally capable of .0001gram accuracy). Electrical conductivity of water is directly related to the concentration of dissolved ionized solids in the water. Ions from the dissolved solids in water create the ability for that water to conduct an electrical current, which can be measured using a conventional conductivity meter or TDS meter. 1) What are the gravimetric methods of measuring total dissolved solids?2) What is TDS?3) What are primary sources for TDS?4) What is TSS?5) What are different between TDS and TSS?.7 Give the best proper term in English after considering the terms listed in the following table carefully, each is 1 point and total points are 10.Technical terms in ChineseTechnical terms in English完整井地下水动态弱透水层地下水径流不透水层储水率越流补给给水度承压水地下水均衡10 / 10文档可自由编辑打印
