Categories Related to Water Quality Measuring Instruments
Water quality measuring instruments are used to measure the contamination of general environmental water, industrial wastewater, oceans, lakes, rivers, and so on.
Tap water, rivers, factory wastewater, etc. must meet specified standards for use and discharge, and the specified items vary depending on the purpose of use. Water quality measuring instruments are used to measure the specified test items. In addition to simple instruments, there are also instruments that specialize in a single measurement item and are used for purposes other than water quality testing, as well as instruments that specialize in multiple items of water quality testing.
In the 1950s, industrialization and urbanization caused pollution from wastewater. Therefore, wastewater discharged by business operators that does not conform to the standards is strictly prohibited, and the recording and preservation of inspection results is also mandatory.
Living organisms and water are closely related, including tap water, rivers, lakes, factory wastewater, swimming pools, hot spring facilities, and septic tanks. From the drinking water that humans consume to wastewater, from use to disposal, is controlled.
The reason why standards are required not only for what people take into their bodies but also for wastewater is that water is circulating. Pollution in rivers and groundwater is released into the atmosphere through evaporation, and after being purified, is returned to people as drinking water.
When water is stored in a cistern, such as in an apartment building, the cistern must be managed by the building owner. When cleaning the cistern and inspecting the management of the cistern water supply, or for cisterns with a capacity of 10 m3 or more, the color, odor, turbidity, and taste must be tested daily, and the residual chlorine must be tested once a week. Water service providers are required by the Water Supply Law to test 51 items of tap water.
Specific examples of measurement items are listed below.
There are various types of water quality measuring instruments. These include moisture meters, conductivity meters, pH meters, refractometers, and residual chlorine meters.
Simple kits that can easily measure residual chlorine and pH are often used in swimming pools and hot spring facilities. Water quality testing kits for daily drinking can measure residual chlorine, pH, turbidity, color, conductivity, etc.
Electric moisture meters can measure water in paper, wood, mortar, and other materials. Since each material has a unique electrical resistance value, the electrical resistance can be used to measure the water content in the material.
Conductivity meters measure the ease with which electricity flows. It can be used to check the quality of water in rivers and lakes as well as to control pure water and boiler water.
Refractometers use the refraction of light to measure the concentration of solutions and include densitometers and saccharimeters. A few drops of sample are dropped onto a prism surface and checked through an eyepiece.
Residual chlorine meters can measure the residual chlorine concentration in tap water, cooking water, swimming pools, and bathhouses. The water is disinfected by chlorine-based chemicals and is measured for confirmation.
The pH meter can measure the properties of aqueous solutions, such as acidity and alkalinity. pH measurement is necessary to control the chemical properties of substances and chemical reactions.
