Conventional methods for the removal of metal ions from water are expensive and inadequate. Hence, other cheaper and easier to handle methods are required. Consequently, the use of agricultural waste materials of no economic value is currently gaining wide acceptance. In this study, Delonix regia pods and leaves were ground, examined and used to remove nickel (II) and copper (II) ions from aqueous solutions. The results show that this agro-waste effectively removes these metals from solution.

In this study, we investigate numerically, using EPANET code, the leaks in a water distribution network (WDN). The old part of Casablanca (Morocco) is used as a case study. The first episode is based on a simulation of artificial leaks on the MATLAB platform using EPANET. The second was a real simulation of artificial leaks. The results obtained are compared with those of a real simulation of artificial leaks caused by the opening and closing of hydrants.

Access to clean and safe drinking water is a basic human right. Poor quality of drinking water is directly associated with various waterborne diseases. This study found that people in rural areas, with older household heads, and large family sizes are significantly less likely to utilize safe drinking water sources. Households with media exposure, education, women empowerment in household purchases, and belonging to the rich segment of society are more likely to utilize safe drinking water.

One of the crucial aspects of developing a forward osmosis (FO) process is making a suitable membrane. In this work, an FO membrane was synthesized by making a polyamide selective layer on an electrospun nanofiber support layer. The prepared thin-film composite (TFC) membrane showed good performance in terms of water flux and salt rejection compared to the commercially available membranes. Also, it showed other good properties, namely porosity, hydrophilicity, and mechanical strength.
