The current study aimed to evaluate two groups of drinking water they are (Commercial Reverse Osmosis ROc, Home Reverse Osmosis ROh) in Al-Muthanna Governorate , Samples were collected (100) water samples from Home Reverse Osmosis ROh and,(100) water samples from Commercial Reverse Osmosis ROc from December 2022 to June 2023.
The study includes the measurement of some physical Parameters such as (Turbidity, Electrical conductivity, Total dissolved solids, Total suspended solid) and some chemical Parameters (pH, Total hardness, Calcium hardness, Sodium, Potassium, Calcium ,Chloride , Phosphates, Nitrites, Nitrates), Indicators of bacterial contamination are also studied, which includes (Total bacterial count), The results showed that the pH values were recorded between(6.2 – 9.2).
The Turbidity values were ranged between (0 – 3.4 NTU), The Electrical conductivity values were recorded between (20-760 μS/cm), the values of Total Dissolved Solids were studied, their values ranged between (14-725 mg/l), while the values of Total hardness were recorded between (75 - 580 mg.CaCo3/l), Sodium values (2.4-327.2 mg/l) ,Potassium values (0 – 9.7 mg/l), Calcium values (19.9-431.4 mg/l) ,
The chloride concentration ranged between (9.9-356.9 mg/l), As for nutrients, the current study recorded of nutrients, as Phosphate values ranged between (0.02-0.62 mg/l), while Nitrite levels ranged between (0.005-0.066 mg/l) and Nitrate values ranged between (1.5-19.2 mg/l) As for the bacterial examination, the total number of Total bacterial count ranged between (0-4000 CFU/ml). .
From the results conclude, that the physical and chemical parameters for ROc , ROh drinking water showed that is no exceeded permissible limits for parameters (electrical conductivity, turbidity, TDS, TH, , Na+, K+, Ca++, Cl¯) , and low concentrations of chemical parameters (No2¯,No3¯, Po4-3) for ROc , ROh drinking water.
