Water quality testing methods
Overview
Water is one of the most abundant resources in nature, a common and precious substance, but it is also a valuable resource for humansDirectly utilized and easily accessible freshwater resources only account for a fraction of the total water volume3%,Very limited.
Water is an excellent solvent, and natural water obtains a large amount of substances during industrial cooling cyclesThese substances exist in a dissolved, colloidal, or suspended state in cooling water, thus formingThe main components of industrial cooling water.
Industrial water requirements
原料用水：Require water to be colorless, odorless, turbidity free, and have a salt contentappropriate
nCooling water:Water should be controlledhardnessSuspended solids, dissolved gases, oilOther organic matter, algae, microorganisms, etc
Analysis of Water
Analysis of water to analyze itshardnessMainly alkalinity. Industrial cooling waterhardnessMainly determined by calcium and magnesium content, industrial divisionAnalysis usually requires testingTotal HardnessHardness and temporary hardness.
