Safety And Quality of Drinking Water: Assessment of Physico- Chemical and Microbiological Parameters in Kru Prishtina

Session

Agriculture, Food Science and Technology

Description

This study shows that water treatment methods have been effective in improving the quality of drinking water. After treatment, physicochemical and bacteriological parameters have improved significantly, including the reduction of turbidity, color, metals and nitrogen pollutants, as well as the elimination of pathogenic bacteria. Electrical conductivity has increased slightly after treatment, while the concentration of phosphates has decreased significantly. Overall, the water treatment has met the required standards for drinking water, ensuring a high quality and safe for consumption. The parameters included are turbidity, pH, chlorides, ammonia, nitrates, nitrites, total hardness, iron, manganese, phosphates, residual chlorine and fecal coliforms. The values are given according to standard methods and the corresponding units, as well as the permitted limits for each parameter. The results show that the treatment has affected the improvement of water quality, significantly reducing the concentrations of pollutants and bringing them within the permitted limits. For example, turbidity decreased from 2.35 NTU before treatment to 0.47 NTU after treatment, while pH decreased from 8.2 to 7.59. These changes indicate the effectiveness of the treatment process in improving water quality. Parameters included free chlorine, coliform bacteria, fecal bacteria, fecal streptococci and total viable bacterial count in physiological conditions. The values are given for specific dates, showing the changes in bacterial concentrations before and after treatment. The results show that the treatment significantly reduced bacterial concentrations, bringing them within the permitted limits. The number of coliform bacteria decreased from 50 CFU/100ml before treatment to 0 CFU/100ml after treatment, while the total viable bacterial count decreased from 17 CFU/ml to 2 CFU/ml. These changes indicate the effectiveness of the treatment process in reducing bacteriological contamination and improving water quality.
