Abstract:
The surface water contains some dissolved contaminants such as iron and manganese salts where the ground water contains ammonia besides the two mentioned ions; hence they are unsuitable as drinking water without appropriate treatment. This study was carried out during the period from February to December 2019. The aim of this work was to make a comparison between certain physicochemical and microbial parameters at two different ground water plants Dalaton (River bank filteration) and Meet Khaqan (conventional ground water plant) in Menoufia Governorate, Egypt. Confirming to data of the physicochemical parameters, the treated water at these treatment plants proved a remarkable enhancement as compared with raw one mainly with the value of TDS, conductivity, turbidity, total alkalinity, iron, manganese and ammonia but treated water for Meet Khaqan plant showed high turbidity ranged from 0.7 NTU to 1.0 NTU compared with Dalaton plant (ranged between 0.16 NTU and 0.65 NTU). For Meet Khaqan plant TDS had high values ranged between 772 and 915 ppm while for Dalaton it ranged from 214 to 270 ppm. Regarding biotic component, it was proved that both total and fecal coliform and algea disappeared more or less completely at the end of the water treatment process in both plants. On the other hand algal examination showed that, there wasn't any phytoplankton in ground water in Meet Khaqan water while Dalaton water plant (River bank filtration) showed anumber of phytoplankton populations in both raw and treated water belonging to three groups namely: Bacillariophyta, Chlorophyta and Cyanophycta. Bacillariophyta represented the most abundant group accounting 76.8 % of total annual crop. Chlorophyta ranked as the 2nd group with 13.8%. Finally, Cyanophyta ranked as 3rd group with 2.7% of total annual crop. From the practical and statistical point of views, it could be possible to conclude that the river-bank filtration (Dalaton) was the most effective method to obtain better potable water.
