The solids that can be filtered in water are called dissolved solids. Whatever contaminated water is found, all contaminated water is damaging to human health and environmental conditions, and the determination of dissolved solids is therefore an important issue. Accredited laboratories carry out these measurements within the scope of water and wastewater measurements.

New production technologies developed in various sectors also carry some environmental problems. These developments are important for the development of industry, but it is also an important fact that environmental conditions are not affected negatively. In various sectors, unused materials of factories, plants, workplaces and large industrial enterprises are called industrial wastes. Some of these wastes are solids and some of them are mixed with wastewaters. Leaving these wastes untreated to nature constitutes industrial pollution. Acids, detergents and toxic metals that cause industrial pollution are mixed with streams, rivers, lakes, sea and underground waters and pollute nature. If industrial pollution exceeds the absorption capacity that nature can accept, this situation is dangerous for human health and environmental conditions.

Acids, zinc, lead, arsenic, copper and similar metals in industrial wastes have toxic effects. These industrial wastes and pollutants, which are mixed with air in the form of steam, gas and fine dust, pollute surface waters, groundwater and soil in the form of precipitation and acid rain.

 

The total amount of dissolved solids determines all solids dissolved in water. To determine the amount of dissolved solids, laboratories must first find a suitable solvent for the water to be analyzed. If the solids do not dissolve in water, dilute acids, concentrated acids and alkali solutions are used respectively. When the solvent is added to the water, gas dissipation in the water or any other action is observed, the sample is heated to accelerate the dissolution process.
