Abstract

Microplastics (MP) can pose a serious threat to the environment and human health because of their tiny size and ability to spread easily in water. One of the alternative treatments to remove MP from water is the rapid sand filter (RSF). The objective of this study was to analyze the effects of filter media size and loading rate on RSF performance in removing MP. The applied filter media was silica sand with effective sizes (ES) of 0.39 and 0.68 mm. The loading rates of filtration were 4; 6; 8 and 10 m3/m2-h. The MP samples were made from plastic bags and torn tires (artificial samples: 10 to 800 µm). This study showed that the MP removal percentage was up to 96.6% (MP size larger than 200 µm). The head loss increment for loading rates 4; 6; 8; 10 m3/m2-h was 0.16; 0.35; 0.34; 0.25 m (ES 0.39 m) and 0.10; 0.18; 0.18; 0.19 m (ES 0.68 m)), respectively. Meanwhile, the filtration cycle for loading rates 4; 6; 8; and 10 m3/m2-h was 5, 2, 2, and 1 days (ES 0.39 mm) and 9, 4, 3, and 3 days (ES 0.68 mm), respectively. The result of this study showed that the smaller the filter media size, the higher the head loss of the filter media bed. Furthermore, there is an increased head loss of the filter media bed when the loading rate is greater.

Abstract

Indonesia is a country that has considerable coal reserves with coal resources of 149.01 billion tons. One of the problems of coal mining is turbidity. The turbidity is caused by the excavation of the open pit mine so that rainwater contact with the main wall. So that mud is formed, which can increase turbidity levels. The concentration of Total Suspended Solids (TSS) due to this phenomenon reaches 5,400 mg/L. Aim: This study aims to set aside TSS by electrocoagulation processing method using a batch system with eight pairs of iron electrodes arranged monopolarly. Methodology and Results: Comparisons using statistically independent t-tests showed that there was no significant difference between the iron and aluminium electrodes in the pH parameter. Conclusion, significance, and impact study:There were significant differences between iron and aluminum electrodes in the parameters of TDS and TSS. In the measured TDS and TSS parameters, the electrocoagulation process using iron electrodes has a higher value than aluminum electrodes. In the TSS removal, there is no significant difference between the two electrodes (iron and aluminium).

Abstract

This research studied the synthesis of immobilized TiO2 microparticle and nanoparticle catalyst materials and evaluated its photocatalytic activity on the decolorization of Acid Red 4 (AR4) azo dye solution. TiO2 microparticles were immobilized on an acrylic plate, while TiO2 nanoparticles were immobilised on a glass plate. TiO2 nanoparticles were embedded in a nanofiber support layer to enhance photocatalytic performance, forming a nanofiber-nanoparticle composite on the glass plate. In the catalyst load 2.0 g/l, the performance of the photocatalytic layer of immobilized catalyst (k '= 0.013/min) was better than that of the suspended catalyst (k' = 0.008/min). Photocatalytic decolorization efficiency of TiO2 immobilized catalysts of nanoparticle sized reached 82.3% in irradiation time of 2 hours, which was higher than microparticle sized catalysts (77.8%). The technique of TiO2 nanofiber–nanoparticle composite showed improved photocatalytic kinetics (k’= 0.018/min) compared to a single layer of nanoparticle catalyst (k'= 0.015/min). Immobilized TiO2 catalysts remain effective with repeated use despite a slight decrease in processing efficiency.

Abstract

The presence of antibiotics in aquatic environments has been known to lead to the development of bacteria with resistant genes. One type of antibiotic that has been found in the environment is trimethoprim, necessitating methods to remove this substance from the environment. Adsorption is a process that has been extensively studied in the field of water remediation. This study aims to investigate the adsorption of trimethoprim by granular activated carbon (GAC). Experiments were conducted by creating artificial wastewater containing distilled water and trimethoprim, which was then contacted with the adsorbent with variations in pH and trimethoprim concentration measured periodically up to the 3rd hour. Trimethoprim detection was performed using a UV-Vis spectrophotometer. The contact time required to reach equilibrium increased with the initial concentration of trimethoprim. The variations in initial trimethoprim concentrations of 5, 10, 20, 35, and 50 mg/L reached adsorption equilibrium after a contact time of 180 minutes with a GAC mass of 3 grams. All the percentages of trimethoprim removal after the contact time of 180 minutes at various concentrations used in this study were above 98%. The pH level has been proven to affect the trimethoprim removal process. The pseudo-second-order kinetic model has a high correlation with the adsorption process of trimethoprim by GAC. The isotherm model suitable for the interaction between trimethoprim and GAC was the Freundlich model.

Abstract

The development of time and technology triggers significant challenges in preserving the environment. Large-scale industry that uses a large quantity of energy and clean water is the main reason environmental management due to industrial activities needs to be considered properly. In addition to liquid wastewater, waste in the form of sludge used in wastewater management is also a new problem that requires special attention. Sludge-based activated carbon (SBAC) is one of the options for utilizing WWTP sludge in low-cost adsorbent materials. The development of SBAC is a promising solution to solving two-way environmental problems. The most used activation method combines thermal and chemical compound impregnation. This paper aims to prove that Palm Oil Mill Sludge (POMS) can be applied as an adsorbent after chemical and thermal activation. KOH 4M was used with a ratio of 1:1 (weight/volume) with pyrolysis heating at 700oC injected with nitrogen gas (N2). Fourier Transform Infrared Spectroscopy (FTIR) test shows SBAC has hydroxyl and carboxyl functional groups, Pore Size Analyzer (PSA) classified SBAC as microporous with 1.7 nm size of SBAC, iodine number is about 821 mg/g, 23.63% of ash content, 62.96% of fixed carbon, 11.5% of water content, and 15.37% of volatile content.
