As their availability, the interests of convertingeggshell waste to low-cost and green adsorbent had been growing for treating thecontaminated water sources. The present study investigated the adsorption performanceof CE with different pre-treatment approaches by means of calculation of removalpercentage and adsorption capacity of total nitrogen (TN), total phosphorus (TP),biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspendedsolids (TSS) from river water. The quality of water sample before and after treatmentprocess are classified based on the Interim National Water Quality Standard for Malaysia(INWQS) and Chemical water quality classification for nutrients developed by WorkingGroup of the Federal States on Water Issues. Adsorption kinetics models and adsorptionisotherms are exploited to test the experimental data. The result revealed that both UTCEand VTCE experiment showed a decrement in pollutants concentration level. Owing tothe presence of acetic acid offers development of larger pore opening on the surface ofeggshell, VTCE presented better percentage pollutants removal and adsorption capacitycompared to the UTCE. For UTCE experiment, TP, TN and TSS has 35.63%, 44.69%and 69.74% of removal percentage. As for VTCE experiment, the percentage of TN andTSS eliminated was 47.21% and 91.67% respectively. 28.57% and 17.5% of BOD andCOD also eliminated by VTCE. The kinetic adsorption follows the pseudo second ordermodel for both UTCE and VTCE adsorbent which the highest regression coefficient is0.9033 and 0.9898 respectively. The adsorption isotherm for both UTCE and VTCE ismore satisfactorily fitted with Freundlich model respectively with maximum correlationcoefficients of 0.9939 and 0.996 respectively. The study demonstrated the efficacy of CEand proved that it as VTCE as viable cost effective adsorbent than UTCE for river waterdecontamination.
