Recently heavy metal pollution is consider among the most essential environmental issues. Due to their impact, the removing of heavy metals from the environment is a high demanding concern. Heavy metals adsorption is a new technology for wastewater treatment that contain different selected heavy metals types. This study aim to adopted adsorbents with low cost application, in this technique a pine cones used as plant wastes adsorbents in Industrial wastewater treatment by implemented batch technique adsorbent dosage and adsorbate initial concentration). The plant waste sample of (pine cone) was used to test its efficiency which that provide the optimum performance in removing heavy metals and other pollutants (Turbidity, TSS and TDS). Activated carbon produced from Pine cones Turkish Pine (ACPC) was adopted as an adsorbent for the Zinc ions removal from wastewater with industrial pollutants. Surface analysis was preform to measure the pore size distribution and specific surface area of the activated carbon produced from pine cone. Optimal parameters, pH, equilibrium time, adsorbent dosage, temperature and mix speed were investigated. Using Langmuir, Freundlech and Elvich isotherm models, equilibrium data were evaluated. Langmuir isotherm model provided the highest fit to the equilibrium data.

The primary goal of this study was to use low-cost adsorbents, this achieves by using pine cones as plant waste adsorbents in the treatment of industrial wastewater. In the experimental work of this study, a system of PVC horizontal pipes of 15cm diameter and 600 cm length without membranes was used. The polluted water values discharged in the system were 20, 40, 60, 80, and 100 L/hr. The effect of many hydraulic parameters (contact time, flow discharge, length of the pipe, and pressure) with environmental parameters (pH, TDS, TSS and electrical conductivity) was investigated in this continuous flow system. The sample of plant waste (pine cone) was treated and activated by ozonation, to manufacture new media with high porosity, activated carbon developed from pine cone (ACPC), and to determine the activity that produces the best results in the removal of heavy metals. To remove Fe+2 and Zn+2 ions from industrial wastewater, activated carbon was used as an adsorbent. Adsorption tests result in an exhibit that, the ACPC adsorbent had remarkable heavy metals removal efficiency. The most effective removal efficiency of 95% of Zn+2 was recorded at pH 7, 20 l/hr, and 5hrs. The higher removal efficiency of 96.67% of Fe+2 occurred at pH 6, 20 l/hr, and 5hr. The study also revealed that activated carbon devolved from pine cones can be adopted as a low-cost alternative for removing metal ions.

The industrial and agricultural waste water contains many contaminants; one of them is the food carmoisine dye E112, which causes a series problems for the environment. Adsorption using porous media is one of the solutions to this problem. In the present work, activated silica sand (ASS), activated carbon (AC), porcelanite, silt and composite porous media, were prepared and used to remove the E112 from waste water using adsorption technique. It was predicted that the removal efficiency was affected by many factors such as time, pH, dose and ozonation of media. These factors were studied and analyzed to investigate the best media which is the activated carbon with the highest removal efficiency than the other porous medias. The results showed that: • The best removal efficiency of carmoisine dye E-112 was by activated carbon (AC) that reaching to 76% under specific conditions (7 of pH, 20g of AC and 10 mg/l initial concentration of dye) which were selected after several attempts until reaching the best results of removal efficiency. • Ozonation (ozon pumping to the porous media) was the effective reason of removal efficiency increasing. • The best one of porous medias according to the removal efficiency was: AC> ASS> composite> porcilanite> silt.
