| Abstract | Many industries have successfully used water recycling. Wastewater reuse for industrial processes, the use of industrial process water between consecutive processes within an industry, and agricultural reuse of industrial plant effluent are all examples of alternative industrial recycling and reuse solutions. The cost-effectiveness of using reclaimed water for industrial applications is determined by the distance between the reclamation facility and the point of usage. Many industrial effluents have been treated by primary treatment and acceptable for discharge to environment. Nevertheless, it is not reaching the reuse standard. Filtration is an efficient method of removing tiny organic and inorganic particles from wastewater. A filtration procedure can also be used to remove pathogens. It is accomplished by allowing influent to pass through filter media. Pollutants or contaminants are trapped in the media material as wastewater pass through it. One of the most effective methods for removing colors, smells, oils, and organic pollutants from waste effluents and processes is adsorption. In terms of the design simplicity, an initial cost of operation, and toxin resistance, adsorption was found to be superior to alternative water reuse technologies. As adsorbents, eggshells are eco-friendly and low-cost that can be used to treat pollution. Eggshell is a significant solid waste source that includes households, restaurants, and the food processing industry. For this study, the highest performing of media in filter column consists of bentonite powder, zeolite, and eggshells and the optimum HRT from BATCH experiment is 24 hours., the system is operated by varying the filtration rate including 0.2, 0.8, 1.4, 2.0 m3 /m2 d. The results from 8 reactors illustrate that media with 0.2 m3 /m2 d is the highest removal performance. R1-0.2 shows the best removal on color, COD, TSS, TDS, TKN, and NH3-N while R2-0.2 indicates the best performance in TP removal. Other reactors give very fluctuate results in all parameters. The desorption process using 1N NaOH solution can desorb the pollutants from adsorptive media especially color, COD and TKN. Although, the lowest amount of TP concentration can desorb. |
