Abstract

Laundry wastewater is one of the contributors to domestic wastewater since laundry services have been increasing in urban living, especially in big cities. Laundry wastewater may contain phosphate compounds, and the concentration should be reduced before discharge into water bodies. One of the easiest and friendly methods for removing phosphate in laundry wastewater is by using the adsorption process. Adsorption is influenced by the adsorbent material, and fly ash has been implemented as adsorbent due to its high capacity to adsorb pollutants. This study aims to observe the effect of adsorbent height in the column and the effect of flow rate to treat phosphate in laundry wastewater. This study applied Thomas modeling to determine the model for fly ash capacity as adsorbent. The results showed that the highest flow rate, 15 mL/min, and the highest fly ash height 20 cm gave the optimum removal of phosphate, about 98.63-99.22%. Besides, Thomas model obtained the value of the linear regression coefficient of 0.5415.

Abstract

The increase in the electroplating industry resulted in a large number of heavy metal wastes that are harmful to the environment, for example, hexavalent chromium waste. The Bintaro which contains cellulose is considered as a potential adsorbent to remove heavy metals. Therefore, a comparative study on the adsorption capacity of continuous adsorption was carried out in reducing the concentration of heavy metal Cr6+ in electroplating wastewater. The characterization itself can be done by testing the moisture content and ash content and SEM testing. The study of the adsorption capacity in a continuous process is generally carried out with Thomas modeling, where this research is carried out by a continuous adsorption process with variations in the adsorbent mass of 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams. The best results were obtained to remove Cr6+ metal which was 94.4% in the Bintaro shell adsorbent type with a mass of 250 grams. The continuous adsorption process obtained the highest Thomas constant (Kth) value and the highest adsorption capacity (qo), namely using Bintaro shell activated carbon with a mass of 250 grams with an absorbance capacity value of 0.443mg / g. The results showed that the activated carbon of Bintaro shell showed that they were quite effective as adsorbents in the adsorption process to remove heavy metal Cr6+
