A novel cost-effective reactive adsorbent, WS/MgONPs, composed of walnut shells (WS) and magnesium oxide nanoparticles (MgONPs) prepared from magnesium acetate tetrahydrate, as verified by FE-SEM, EDX, BET, FTIR, and XRD studies. Was synthesized and shown excellent removal of tetracycline (TEC) from wastewater. The synthesized WS/MgONPs performed various batch and fluidized bed column studies to ascertain the optimal employed parameters. Results showed that WS/MgONPs adsorption capacity increases with the concentration gradient. A 0.07 g of the adsorbent was proven sufficient to remove >87.4% of TEC initial dose of 50 mg/L in 1000 mL of deionized water with an agitation speed of 200 rpm for 70 min. The adsorption isotherms conformed to both the Langmuir and Freundlich models, but the Langmuir model exhibited a more accurate fit to experi- mental data, with loading capacity determined to be 216.511 mg/g at pH 7 and 25◦C, while the pseudo-second- order model most accurately characterized the absorption kinetics, obtaining a rate constant of k2 = 0.0025 g/mg min. Fluidized bed columns with various operational conditions were used, the minimum fluidization velocity (Vmf) of the bed was influenced by flow rate (Q), bed height (HS), and initial concentration (Co). Experiments work revealed that decreasing flow rate and concentration of TEC, while enhancing the sorbent mass, sub- stantially extended the effective lifetime of the synthesis sorbent inside the fluidized bed column. The observed breakthrough curves were optimally fitted using the Thomas (TH) model, which yielded the greatest R² values with the minimal sum of squared errors (SSE). Finally, the results obtained highlight the novel synthesized WS/ MgONPs exceptional effectiveness and eco-friendly in addressing TEC in pharmaceutical wastewater, estab- lishing it as a viable option for sustainable and economical wastewater treatment solutions. This study provides significant insights into the creation of improved adsorption materials for pharmaceutical adsorption in waste- water treatment.

Methylene blue (MB) is a well-known dye that is used in many industries and is highly polluting to the envi- ronment. Therefore, this paper proposes using sunflower husks (SFH) through a coating with a nanomaterial made of silicon dioxide (SiO2) with a weight percentage (w/w) of 5:1 to produce (SFH-SiO2) nanoparticles for removing MB from aqueous solutions. This method, known as green synthesis, is characterized by being envi- ronmentally friendly and low-cost, as well as efficient in the removal process. The prepared composite was characterized by conducting analysis using Field emission scanning electron microscopy (SEM) with (EDX), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) were used to look at the samples. The optimal conditions for the removal process were found to be at a pH of 6, with 0.2 g/50 mL of dose adsorbent. At a temperature of 25 ◦C, the best time to remove the dye was 150 min. With a maximal adsorption capacity (qmax) of 70.16 mg g−1, the findings match the Freundlich model. The adsorption process follows a pseudo-second- order. The negative value of Gibbs free energy (ΔG◦ ) indicated the reaction was spontaneous. (SFH-SiO2) nanoparticles could represent a suitable method for removing cationic dyes from aquatic environments.

Antibiotics are one of the new contaminants that, if not effectively regulated, might have detrimental impacts on both human health and the aquatic environment. Trimethoprim (TRM) is one of the most often used antibiotics, and in recent years, its presence in aquatic environments has raised significant concerns because of its persistent actions. In this study, green synthesized nanoparticles consisting of walnut shells (WS) and zinc oxide nano- particles (ZnO) were used to produce walnut shells loaded with zinc oxide nanoparticles (WS/ZnONPs). Adsorption with synthesized WS/ZnONPs as an adsorbent to reduce TRM from aqueous solutions showed high TRM removal efficiency (84.6%) with a maximum adsorption capacity of 118.782 with the Langmuir isotherm model (R2 = 0.990). When optimal parameters are achieved, pH 5, dosage 0.2 g per 100 mL, particle size 63 μm, vibration speed 200 rpm, 110 minutes, and temperature 25 ◦C. This maximum adsorption capacity was seen at an initial concentration of 50 ppm. A pseudo-second-order model can accurately describe how TRM binds to WS/ ZnONPs. This is shown by the high coefficient of determination and strong agreement between model predictions and experimental adsorption. Furthermore, the results indicate that intra-particle diffusion is not the primary mechanism governing the adsorption process. Thermodynamic analysis showed that TRM adsorption onto WS/ ZnONPs was exothermic, spontaneous, and practicable. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) are used to describe how WS/ZnONPs are made. The results show that WS/ZnONPs serve as a highly effective adsorbent for removing TRM from aqueous solutions.

The present research deals with the impact of the quality of water sources as an alternative to tap water on the hardened and fresh characteristics of self-compacting mortar. Laboratory chemical tests were car- ried out for water samples collected from four sources- non-potable well water, Tigris river water, untreated wastewater from local factories, and tap water. Water from the four sources was used to pour self-compacted mortar specimens in presence of ground granulated blast furnace slag (GGBFS) as poz- zolanic materials up to 30% with 10% increment which replaced with cement by weight. Slump flow diameter, V-shape flow time, compressive strength, flexural strength, and water absorption ratio tests were performed for self-compacted mortar specimens. The experimental results showed a slight improvement in slump flow of self-composted mortar mixtures using non-potable well water in the pres- ence of 10% GGBFS. There is a significant improvement in slump flow for mixtures that used Tigris River water as an alternative to tap water. The compressive strength of self-compacted mortar at 7 and 28 days using Tigris river water, in the presence of10%, 20%, and 30% GGBFS were developed better than non- potable well water and untreated wastewater.

This paper studied the effect of waste Polyethylene Terephthalate (PET) on the workability and mechanical properties of the produced cement based mortar. However, five different waste PET weight fractions of 0, 5, 15, 25 and 50% were replaced with river sand in cement mortar mixtures with constant cement content and water to cement ratio of 525 kg/m3 and 0.48, respectively. The workability of the mixtures is enhanced by increasing the replacement level of plastic waste PET. On the other hand, the dry density, compressive and flexural strengths were reduced as waste PET incorporation increased except the mix contained 5% of PET which improved the compressive and flexural strengths. As a result of the dry density and compressive strength results, it was determined that the mixture containing 25% waste PET is considered as a lightweight mortar and suitable for structural purposes.

In this research, an experimental laboratory plant was constructed in order to evaluate the effect of nitrogen and phosphorus loadings and recirculation ratio on the nutrient removal efficiency of trickling filter. The plant consisted of four biological trickling filter similar in shape, each with a volume of (35 liters). Synthetic wastewater was used to operate the plant. To study the impact of recirculation ratio on the system, three of these plants (first, second and third) were operated on recirculation ratio of (100%, 200% and 300%) respectively, whereas the fourth operate without recirculation. The study program was divided into nine stages, in the first three stages the nitrogen loading was (0.12 kg/m3.day) then increased to (0.17 kg/m3.day) and (0.21 kg/m3.day) and the phosphor loading was (0.02 kg/m3.day) then in the fourth, fifth and sixth stages the phosphor loading was (0.03 kg/m3.day) increased to (0.04 kg/m3.day) in the seventh, eighth and ninth stages respectively while the nitrogen loading still increased in the same ratio rate. The results of the study revealed that; the removal efficiency of the biological trickling filter increase when the recirculation was applied, and the efficiency increased with recirculation ratio increase. The result also showed that; increasing each of the nitrogen and phosphorus load leads to an increase of the effluent concentration of ammonia and phosphorus for all of the applied recirculation ratio at the research .

In this research, an experimental laboratory plant was constructed in order to evaluate the effect of recirculation ratio, organic loading and suspended solids loading on the removal efficiency of trickling filter with plastic media. The plant consisted of four biological trickling filter which were similar in shape, each with a volume equal to (35 liters). Synthetic wastewater was used to operate the plant. To study the impact of recirculation ratio on the system, three of these plants (first, second and third) were operated on recirculation ratio of (100%, 200% and 300%) respectively, whereas the fourth operated without recirculation. To study the effect of increase organic loading, the study program was divided into nine stages, in the three continuation following stages the organic loading rate was steady then increasing in the three suffix continuation following stages thus until ultimate ninth stage, beginning with (1.5 kg COD/m 3 .day) then (2.1 kg COD/m 3 .day) and up to (2.7 kg COD/m 3 .day). The results of the study revealed that; the removal efficiency of the biological trickling filter increase when the recirculation operation was exist, and the efficiency increased when increase recirculation ratio, so the average efficiency of first stage removal of organic loading was in the trickling filters (first, second, third and fourth) (84.5%, 86.3%, 87.5%, 80%) respectively. The results also showed that; increasing organic and suspended solid loading decreases removal efficiency of organic matter, ammonia and phosphate.‬
