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.

Abstract

The aim of this research was to determine the removal of Total Suspended Solids and fatty oils using the grease trap and filtration methods. Based on the results of experiments that have been carried out, the removal efficiency of Total Suspended Solid at various residence times reached 99.09% (12 hours), 97.89% (24 hours), 98.65% (36 hours), 98.89% (48 hours), 99.18% (60 hours), and 99.3% (72 hours). Fatty oil removal over a period of 12 to 72 hours reached 99.99%. The use of grease traps and filters with biochar rubber and sand media shows that this treatment has proven effective in reducing levels of Total Suspended Solids and fatty oils to meet domestic wastewater quality standards.

Abstract

This study aims to determine the effectiveness of B3 wastewater treatment using the steam distillation method applied by the wood industry of PT X Jambi Province. Observations were made during activities in the September-November 2024 period. The parameters observed include TSS, BOD5, COD, phenol, total ammonia, and pH. The WWTP consists of several main components: initial collection basin, distillation basin, condenser, distillate collection basin, reuse basin, and indicator basin. The water used in the process of washing and maintenance of the glue spreader machine is partly wastewater that has been processed through the WWTP (reuse) with a daily average of 1.408 m3 / day. The analysis results show that all parameters are below the maximum limit of quality standards according to Permen LH No. 5 of 2014. The distillation method is proven to be effective in reducing contaminant levels and producing water that is suitable for reuse in industrial processes.
