The research is a study of some physical and chemical characteristics of three water
purification stations in Baladruze District , Diala Governorate, which are supplied with water
from Al-Ruze river a branch of Diala river ,The samples of the study are taken from the
surface monthly from January to December 2009, the results shows that the (pH)
concentration values are in the weak alkaline above the equivalent ratio of the (pH) for all the
stations during all the months of the year , the results also show that the water studies samples
contain salt ratio within the permitted ratios for drinking water in the most months of the year
, New Baladruze station recorded the lower ratio (235 ) ppm compared with the two other
stations, whereas the Old Baladruze station recorded the higher ratio in January (320 ) ppm ,
the electrical conductivity measures show that it increase with the increasing the quantity of
total dissolved solids in the water ,the ratio of dissolved oxygen approximate values (8-12)
ppm during the year ,the results of total hardness of water show that the studied water samples
were within the degree of hard water for the most months of the year , Baladruze water station
(Million Gallon) recorded less ratio of Total Hardness (164.3) ppm ,the magnesium and
calcium concentration ratio showed that the high ratio of calcium is ( 71.4 ) ppm in Baladruze
station (Million Gallon ) , and the low ratio was in New Baladruze water station (38.9 ) ppm ,
magnesium concentration values for all the months of the year was universal for calcium
concentration ratios in all the stations , as for water turbidity was between in congruent in
some months it recorded ( Turbidity > 5 NTU) and congruent with the permitted
qualifications for most months of the year in all water purification stations . |
