Abstract

The Alhagi Maurorum (AM) is used as a coagulant aid to support the action of coagulant factor in grey water treatment; alum could be accounted as the mean chemical coagulant and Alhagi Maurorum (in two separated forms: powdered and extracted liquid) as the coagulant aid. A series of experiments were managed to find the optimum dosage of AM and optimum pH condition so as to achieve higher removal efficiencies for the contaminants such as turbidity, chemical oxygen demand (COD) and total suspended solids (TSS) originated in synthetic grey wastewater. Using AM as an extracted liquid was better than the powdered form. The results showed that the combination of 40 mg/l of alum and 1.0 ml/L of extracted liquid AM achieved reduction efficiency for (Turbidity, COD and TSS) by (98%, 92%, 95%) at pH=10. The results showed the possibility of the application of AM as natural coagulant. The positive impact or possibility of the application of AM as natural coagulant
