يهدف هذا البحث إلى:
تحديد قيم الpH المثلى للوصول إلى أعلى كفاءة لإزالة معدن الكروم الموجود
في مياه الصرف الصناعية الناتجة عن المدابغ و ذلك بالترسيب الكيميائي.
الوصول إلى تركيز قريب للتركيز المسموح به للكروم في مياه صرف المدابغ
المعالجة حسب المواصفة القياسية السورية رقم ( 2580 )\2002 جدول ( 1 ).
This research aims to:
Determination of optimal pH values to reach the highest
efficiency of chromium removal in industrial wastewater from
tanneries by chemical deposition.
Access to close concentration of the permitted
concentration of chromium in treated tannery wastewater
according to Syrian Standard No. 2580/2002 (Table 1).

The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The
