Abstract

Salinity in drinking water poses significant health risks and challenges for water sustainability. Although there are varieties of water treatment technologies are available, low cost, and efficient alternative of water treatment is always appreciable. This study explores the effectiveness of various adsorbents in removing salt ions from saline water. Wood waste being a source of natural biodegradable cellulosic fiber content has a potentiality to produce activated carbon under proper condition. Twenty samples from three selective wood waste have been produced using same activating agent at different activation temperature, activation period and these activated carbon samples were systematically analyzed to optimize removal efficiency in both batch and column adsorption at different rpm of analyzer, dosing of adsorbent, contact time of adsorbent and initial chloride concentration of water. It has been found that Swetenia Mehagony impregnated with H₃PO₄ acid (1:1) ratio at 900 ∘ C activation temperature for 2 h has shown the best result of removal efficiency of 56.56%. Another finding is that Gmelina Arboreaare and Acacia Auriculiformis impregnated with H₃PO₄ (1:1) at 800˚C activation temperature and for 2h activation period shows the maximum removal efficiency of 47.64% and 48.58% respectively. The controlling factor that affects the removal efficiency also analyzed such as adsorbent dosing rate was 4g/l, best rpm of the batch analyzer was found 120, initial concentration 500mg/l was more efficient and ideal adsorbent contact time was 180min. The results of equilibrium adsorption investigations have been fitted into various adsorption models including Langmuir and Freundlich.
