Opis:: The Basrah province (southern of Iraq) was interested in establishing desalination plants to provide drinking water due to the high levels of salinity in its water resources. This work was carried out in order to evaluate and simulate the functionality of the reverse osmosis plant in the Al-Maqal port. From the field and laboratory measurement, this study concluded that the considered parameters of product water by reverse osmosis (RO) plant were within the Iraqi standard (IRS) limits. The calculation of operation indices showed that the recovery rate of plant (72%) and the permeate flux of plant (20 lmh) was within for limitation of brackish surface water. In turn, the plant has a low salt rejection (90.1%) and a high pressure drop (5 bar); therefore, the membranes require backwashing or chemical cleaning. Then, the performance of RO membrane was simulated by the Winflows software. The best operating parameters were identified. The coefficient of determination (R2) between simulated and measured TDS was 0.83. Therefore, the simulated TDS of permeate multiplied by 5.3 was given a good estimation for actual TDS within acceptable an error rate of 17%.

Opis:: Shatt Al-Arab River in Basrah province, Iraq, was assessed by applying comprehensive pollution index (CPI) at fifteen sampling locations from 2011 to 2020, taking into consideration twelve physicochemical parameters which included pH, Tur., TDS, EC, TH, Na+, K+, Ca+2, Mg+2, Alk., SO4-2, and Cl-. The effectiveness of multiple linear regression (MLR) and artificial neural network (ANN) for predicting comprehensive pollution index was examined in this research. In order to determine the ideal values of the predictor parameters that lead to the lowest CPI value, the genetic algorithm coupled with multiple linear regression (GA-MLR) was used. A multi-layer feed-forward neural network with backpropagation algorithm was used in this study. The optimal ANN structure utilized in this research consisted of three layers: the input layer, one hidden layer, and one output layer. The predicted equation of the comprehensive pollution index was created using the regression technique and used as an objective function of the genetic algorithm. The minimum predicted comprehensive pollution index value recommended by the GA-MLR approach was 0.3777.

Opis:: Water pollution has increased due to human activities; consequently, it is essential to treat both surface water and ground water so they are suitable to meet the needs of the population. This study will discuss water treatment intended to remove antimony. Antimony (Sb) is classed as a high-priority toxic pollutant because of its adverse effects on ecosystems and human health. There are several methods for removing antimony from water, including adsorption, coagulation, ion exchange, and electrochemical treatment. This study focuses on the adsorption method as researchers have, in recent times, been seeking adsorbents that are environmentally friendly and cost-effective and that do not leave a residue. The study investigates the use of orange peels treated with acetic acid as an adsorbent to remove antimony ions from a simulated aqueous solution. The results revealed that 5 g of treated orange peels is 98.5% effective at treating water at a pH of 6, for a contact time of 150 minutes, at a mixing speed of 450 rpm.
