Coagulation process was conducted using different dosage from date stone powdered (0.2-10 g/L) and different pH values (5-10) using orbital shaker at 200 rpm. The treatment efficiency was evaluated by examine the removal for chemical oxygen demand (COD), total suspended solids (TSS), ammonia-nitrogen (NH3-N), manganese (Mn), iron (Fe), zinc (Zn), alu-minum (Al), and nickel (Ni). The maximal removal for COD, TSS, NH3-N, Mn, Fe, Zn, Al, and Ni were 59.4%, 99%, 92.1%, 87.1%, 97.7%, 94.8%, 65.8%, and 80.3%, respectively. Date stone powder has enormous promise as a plant-based natural coagulant for industrial effluent wastewater treatment and might be used to treat effluent from the iron and steel industries.eninfo:eu-repo/semantics/closedAccessNatural coagulantIndustrialWastewaterTreatmentRemovalCoagulation-flocculationArticle10.5004/dwt.2023.293932-s2.0-8515814207045Q339287WOS:000982607500005N/A
