地下水供应应经过全面水质检测，以确保适合饮用水和乳制品生产用途。对从Buraydah Al-Sag含水层提取的地下水中去除污染物的化学特征和微生物质量进行了评估，Qassim地区进行了研究。经测试的井源和污水水样的溶解固体总量、电导率和浊度值均在沙特标准和世卫组织准则的可接受范围内。乐动KENO快乐彩当然，由于采用的处理工艺，EC和TDS的浊度降低率相同(58.6 ~ 93.6%)，但浊度降低率为0.0 ~ 100%。总碱度、氯化物、硝酸盐和硬度等化学特性也在沙特标准和世卫组织指南的允许范围内。乐动KENO快乐彩所采用的处理工艺的有效性使处理后地下水中这些化学参数的百分比分别降低了约54-82.9,56.9-82.6,29.0-95.8和7.9-98.2%。此外，原水和处理后的地下水中铁和镉等矿物质含量均低于检出限。地下水含氟量低于当地和国际标准所规定的容许限度;因此，饮用时必须考虑氟化工艺。处理后的水锌含量在沙特标准和世界卫生组织准则所要求的允许浓度范围内。乐动KENO快乐彩 While, nickel and lead contents in three groundwater sources were found to be higher than those postulated and recommended by the Saudi standards and WHO guidelines. However, water treatment at all studied stations was fair enough to remove these hazards and secure water. In regards to microbiological quality, the treated groundwater was found to be totally free from coliform organisms with almost undetectable level of viable count rendering them quite safe for drinking use and dairy-food processing.
