Abstract

Zeolite as an adsorbent has been widely used. Zeolite activation was carried out to increase the absorption. This study aimed to determine the characteristics of the active zeolite and apply it as an adsorbent. The activation process was carried out by adding acid and calcining at 4500C for 6 hours. Remazol Yellow FG is a dye that is widely used in the textile industry. In this study, the adsorption process was carried out on the Remazol Yellow FG solution, then analyzed the effect of changes in pH (5, 6, 7, 8, 9), contact time (30, 60, 90, 120, 150 minutes) and the concentration of Remazol Yellow FG solution ( 50, 100, 150, 200, 250 ppm) on the adsorption of Remazol Yellow FG dye. From the analysis of the sample solution of Remazol Yellow, the values of Ce and qe can be calculated. These values were then used to calculate KL and KF in the Langmuir adsorption isotherm and Freundlich adsorption isotherm models. From the experimental results, it could be seen that as the contact time increased, the adsorption capacity would be greater. However, when the zeolite was already in the saturated phase, the adsorption capacity would tend to decrease. In the Langmuir adsorption isotherm, the KL value was 0.0274 L/mg and in the Freundlich adsorption isotherm model, the KF value was 29.25 L/mg. Remazol Yellow FG adsorption tended to follow the Langmuir adsorption isotherm model with an R2 value of 0.998.

Abstract

This study aimed to treat tofu wastewater using electrocoagulation and filtration methods with tamarind seed media. This study was conducted on a lab scale with a capacity of 2 liters, using Al-Al electrodes with a voltage of 13 volts. The variables studied were EC time (20, 30, 40, 50, and 60 minutes) and electrode plate area (90 cm2 and 99 cm2) with a thickness of 1 mm. The parameters measured were COD and TSS of tofu wastewater before and after treatment. The results showed that the electrocoagulation and filtration methods with tamarind seed media could reduce the COD and TSS levels of tofu wastewater significantly. The optimal condition was achieved at EC time of 50 minutes and plate area of 99 cm2, with COD removal of 78.7% and TSS removal of 88%. This was due to the production of metal ions (Al3+) as destabilizing agents at the anode, the formation of flocs by protein and tannin in tamarind seeds, and the pH reduction by ascorbic acid and citric acid in tamarind seeds. This method had the advantage of not using synthetic chemicals and producing a more environmentally friendly final product.
