Abstract

Recent studies have explored various adsorbent materials that are low-cost, available in quantity, and effective for heavy metal removal, one of them is the Water Treatment Plant (WTP) sludge. The study aimed to investigate the potential of recycling Water Treatment Plant sludge into an adsorbent for Cu (II) removal. The sludge adsorbent was carbonized by using a furnace at 600°C for 2 hours. This study was conducted in batch. The adsorbent effectiveness was analyzed by varying the dosage, contact time, and activation of the sludge adsorbent on Cu (II) removal. The adsorption isotherm was analyzed using the Langmuir and Ferundlich models, and the kinetic study used pseudo-first-order and pseudo-second-order model. The results showed the removal efficiency of Cu (II) for both activated and non-activated sludge adsorbents reached 98.6–99.9%. The addition of dosage did not affect the increase in Cu (II) adsorption capacity. Activation of the adsorbent increased the adsorption capacity of Cu (II) with the equilibrium time at 60–90 min, shorter than the non-activated adsorbent at 90–120 min. The adsorption isotherm model for both adsorbent types fitted well to the Langmuir model, indicating the adsorption process occurs in a single layer on a homogeneous surface. The adsorption kinetics followed pseudo-second-order with a high correlation coefficient. Water treatment sludge, an industrial by-product, has the potential to be an effective and low-cost adsorbent material for Cu removal.

Semakin tinggi kecepatan pengadukan, semakin baik efisiensi penghilangan merkuri. Hasil penelitian menunjukkan efisiensi penyisihan sebesar 95%, dan efektivitas lumpur IPA PDAM sebagai adsorben sangat baik dengan aktivasi (TAVB) terlihat pada efisiensi penyisihan hingga 95%, karena aktivasi adsorben meningkat. daerah pori daerah adsorpsi. Model isoterm yang cocok untuk penelitian adsorpsi lumpur IPA PDAM adalah Isoterm Langmuir. Rata-rata persentase penurunan pengaruh ketiga dosis, waktu kontak, dan kecepatan adsorben terhadap sisa lumpur aktif mempunyai kemampuan menyerap merkuri sebesar 93%, sehingga hasil tersebut dapat menunjukkan bahwa lumpur limbah PDAM IPA dapat dimanfaatkan sebagai bahan baku. Adsorben dalam pengolahan limbah logam berat seperti merkuri. Hal ini dimungkinkan karena lumpur PDAM IPA dengan aktivasi telah menyerap merkuri sehingga permukaannya tertutup dan pori-porinya mengecil.

Abstract

Carbon monoxide (CO) is a compound that has no smell, taste or color. The compound carbon monoxide (CO) originates from vehicle exhaust emissions from incomplete engine combustion, when exposed it will have an impact on disrupting the path of oxygen binding to hemoglobin in the blood. The Mendalo Darat road is one of the busiest roads in Jambi Province, so it is prone to traffic jams due ti the dense mobilization of motorized vehicles. This can result in a decrease in ambient air quality due to the concentration of carbon monoxide (CO) compounds. This study aims to determine the quality of ambient air in the parameters of carbon monoxide (CO) on the Mendalo Darat highway and the resulting emission rate. Based on the research results for 3 days, namely Sunday (Weekend), Monday, and Tuesday (Weekday), it shows that the highest density is on Tuesday morning which is 17,994 units. Meanwhile, the lowest vehicle volume was on Sunday afternoon point III with a vehicle volume of 6.576 units. The results showed that the highest carbon monoxide (Qco) emission rate on Sunday was at point I in the afternoon of 97.114 µg/m.s, at point II in the afternoon that was 52.665 µg/m.s, and point III in the afternoon wa 52.644 µg/m.s. on Monday, the highest emission rate of carbon monoxide (Qco) was at point I in the afternoon of 106.830 µg/m.s. followed by point II in the afternoon, which was 86.795 µg/m.s on Tuesday, and point III, which was 86.749 µg/m.s. on Tuesday, point I with the largest carbon monoxide (Qco) emission rate was 114.290 tn the morning, followed by point I, which was 109.601 in the afternoon

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.
