Evaluation of the water quality of the drinking water from the chemical side of the area (Adri Alshati ) and the extent of its need for purification operations

Abstract

Due to the spread of desalination shops in many Libyan cities and the dependence of people on the use of desalinated water until it became the main source of use. Most of these stations are not subjected to calibration and evaluation, which leads to consumption of water which may lead to negative impact on the health of the community. This study, which was concluded after conducting tests and tests on drinking water samples in Adri region before and after treatment and obtaining the results, The well contains a few concentrations of (calcium - magnesium), which was less than the optimum and increased the decrease of concentration of these salts after the passage of The results showed that concentrations (sodium - potassium - nitrate) were within the permissible limits in both well water and networks and precipitation. The study showed that concentrations (iron - manganese - chlorides - sulphates - total dissolved salts) exceeded the limits Which are allowed according to the standard Libyan specifications in the well water. This is due to the geological nature of the area and the rise of the iron ore after the passage of the water And the treatment with precipitation decreased most of the concentrations until they were very close to the permissible limits. The natural properties of the water resulting from the precipitation treatment process which were tested were in accordance with Libyan standard specifications with some relatively acceptable differences. Any other treatment recommended this study to encourage the implementation of sedimentation and seek to develop the best and easiest ways that the population can apply and use.
