| چکیده مقاله |
| Given the challenge of water scarcity, addressing the water crisis necessitates the utilization of unconventional water sources or waters of suboptimal quality. The textile industry, one of the largest water-consuming sectors globally, generates and discharges substantial volumes of wastewater. Due to various pollutants, this wastewater is considered highly hazardous and impactful when released into the environment. This study aims to treat unconventional water (textile wastewater) using polyaluminum chloride (PACL), with a survey on the effects of chlorine (Cl) and lime (CaO). This experimental study involves a real effluent sample from a textile dyeing factory. After sampling the effluent and transferring it to the laboratory, parameters such as TSS, COD, pH, EC, TDS, turbidity, and color were measured. The study then analyzed the effects of three doses (1, 1.5, and 2 gr/L) of PACL coagulant in the presence and absence of Cl and CaO on these parameters. The findings indicated that adding 1.0 gr/L of PACL, along with Cl and CaO, reduced the concentration of pollutants such as COD and TSS in raw wastewater by about 94% and 98% respectively. Therefore, the coagulation process with the aid of CaO and Cl can be effectively used to improve the quality of textile effluent, making it a viable unconventional water source for water resources management. |
