Physico-Chemical Analysis

Physico-Chemical Analysis

Risks in drinking water are physical, chemical and microbiological risks. Physical risks include exposure to heat and radiation, chemical risks include organic substances, toxic minerals and toxins, and microbiological risks include bacteria, pathogenic viruses and parasites. These are critical factors that affect water quality and pose a threat to human health. In particular, microbiological risks are the most risky and most difficult to improve. Therefore, in order to determine the microbiological quality of drinking water, it is necessary to check the water at frequent intervals.

The main physical analyzes in water are:

  • Determination of color and odor of water
  • Determination of taste
  • Determination of pH
  • Determination of electrical conductivity
  • Determination of oxidability
  • Determination of evaporation residue

The main chemical analyzes in water are as follows:

  • Determination of the amount of ammonium
  • Determination of nitrite content
  • Determination of sulphate content
  • Determination of iron content
  • Determination of chloride content
  • Determination of total chlorine content
  • Bacteriological analysis

The physico-chemical properties of the waters are different in terms of Turkish Standards Institute (TSE), European Union Countries, World Health Organization (WHO), American standards (EPA) and German standards (DIN).

Arsenic, chromium, cadmium, mercury and lead chemicals which are risky for human health should not be included in the water content. In addition, substances such as nitrate, barium, ammonium and chloride, as well as radioactive substances, should not exceed the limit values. These are all chemicals that harm human health. Likewise, the detection of these chemicals is an indication that some pollutants are mixed into the water.

Hardness of water is the result of the presence of ions such as calcium, iron, manganese and magnesium dissolved in water. Magnesum and calcium ions are more common in natural waters. Therefore, the sum of these ions is expressed as the hardness of water.

 

Our organization From ÖSAS Accreditation Agency, Based on the accreditation authority it receives in accordance with TS EN ISO / IEC 17025 standard, it performs physico-chemical analyzes within the scope of water analyzes in line with the needs of the enterprises.
