The separation mechanism of proteins on a charged ultrafiltration membrane was analyzed using the extended NernstâPlanck (N-P) model. The model was solved numerically based on experimental data during ultrafiltration of bovine serum albumin/BSA and hemoglobin at various pH (between 5 and 8) to obtain the flux parameter (Jv). The flux parameter was used to determine the effective charge of the membrane (f) and the actual membrane porosity (Ak). These two parameters were then used to predict the transport mechanism of proteins through the charged membrane. Higher flux was obtained during the ultrafiltration of BSA compared to hemoglobin. The most effective separation of mixed proteins occurred at pH 5 (aalbumin= 5). In addition, the mobility of a single protein was lower than when it was mixed with other proteins that had different charges. The effective charges of the membranes were varied between 0.99996 to 1.0000, which means that the fixed charge on the membrane structure was higher than the concentration of proteins, thus the effective charge of the membrane was not influenced by the presence of protein charge at various pH. On the contrary, the value of Ak was influenced by the type and charge of the proteins. A decrease of negative charge along with an increase of solution pH increased the porosity of the membrane, thus reducing the rejection of proteins.

Cimahi Subdistrict in Cimahi City, Indonesia has two problems related to clean water and tempeh industry wastewater. The communities Cimahi Subdistric used groundwater that contains high concentration of organic compounds as well as dissolved minerals. Meanwhile, the liquid waste from tempe industry was not treated properly, and consequently, it polluted the river when disposed directly. This activity provided technology to solve the mentioned problems in Cimahi Subdistrict, namely ultrafiltration (UF) and integrated electrocoagulation - ultrafiltration (EC-UF) units. In groundwater treatment using UF membrane, the water product meet drinking water quality standards. The integrated EC-UF reduced the turbidity levels of tempeh industry wastewater to below 5 NTU and BOD by 60%. The EC units can be integrated with biological process as the second treatment to produce more clean effluent. This technology can be used as an alternative of green technology for water and industrial wastewater treatment

Fouling has become the main problem in long-term application of ultrafiltration (UF) membrane for water and wastewater treatment, significantly reducing membrane productivity. In this paper, fouling on polysulfone-based membrane was analyzed using Hermia’s model during textile wastewater treatment. The UF membrane has been prepared by blending polysulfone (PSf), acetone, and PEG400 in DMAc, with ZnO nanoparticles at a concentration of 1% by weight of polymers (PSf and PEG400). The influence of polysulfone concentration (18 and 20 wt.%) and PEG400 (0 - 25 wt.%) on fouling mechanisms was investigated. It was found that the increase of polysulfone from 18 to 20 wt.% reduced permeate flux from 54 to 25 L.m-2.h-1. Vise versa, the increase of PEG400 concentration enhanced the permeate flux. More stable flux was achieved when 18 wt.% of polysulfone was used to prepare the UF membrane. The fouling type in the UF membrane depends on the characteristics of the membrane. A significant flux decline occurred when used 20 wt.% of polysulfone without the addition of PEG400. Smaller membrane pore and higher hydrophobicity due to high polysulfone concentration induced cake layer of fouling on the membrane surface at the first 40 minutes of ultrafiltration. Further increase of operating time, internal fouling was formed due to the movement of pollutants to the permeate side caused by different concentrations. The highest color rejection (86%) was achieved when 25 wt.% of PEG400 was added in 20 wt.% of polysulfone solution.Keywords: fouling, hermia model, ultrafiltration, wastewater treatment.

Wastewater reclamation and reuse have become an alternative to saving operational costs while reducing the impact of waste pollution. In this paper, integration of electrocoagulation (EC) and polysulfone-based ultrafiltration (UF-PSf) membranes were used for the mentioned purpose. The EC unit equipped with 7 (seven) pieces of E-shaped of Al electrodes, which operated at a current of 3 (three) Amperes and a residence time of 2 (two) hours. The waste samples obtained from textile and oil palm industries. The experimental results were compared based on product quality and economic feasibility. When used for textile waste treatment, the integrated EC-UF units reduced TDS, TSS, BOD, and COD by 77%, 95%, 70 -80%, and 60-70%, respectively. While in palm oil waste treatment, the TDS and TSS reduced by 92% and 98%. The electrode loss rate in palm oil waste treatment was 2 (two) times greater than textile waste. By assuming that the waste production capacity of both industries was 400 m3/day, the water production cost in textile waste treatment was Rp. 4,000/m3. While in the palm oil waste treatment, the water production cost was Rp. 6,000/m3. These results showed that the EC-UF unit could be used as an economical and environmentally friendly alternative process for reclamation of industrial wastewater that meets the clean water quality standards.Keywords: electrocoagulation, industrial wastewater, ultrafiltration, reclamation, reuse water

The availability of healthy well water is still become a problem in several areas in Indonesia, including Cimahi City, West Java. In general, the well water is treated using sand filter and adsorbent (either activated carbon or zeolite). However, the conventional methods produced unsafe drinking water, which does not meet drinking water standards. This study proposed integrated polysulfone ultrafiltration (UF), activated carbon (KA), and ion exchange resin (IE), as an alternative technology. The UF membrane provided a permeate flux of 42 L.m-2h-1. Based on Hermiaâ€™s model, the fouling was dominated by total and standard fouling with R2 values of 0.8989 and 0.8952, respectively. During the 2 (two) hours of filtration, the permeate flux decreased by 19%. Based on data from the analysis of water products, the UF-KA unit reduced hardness, organic matter, iron, and other contaminants to below the threshold value for drinking water quality standards. However, the concentration of manganese compounds was still 0.601 mg/L above the standard threshold (0.4 mg/L). With the addition of the IE unit after the UF-KA process, the water products produced meet the drinking water quality standards. The removal of turbidity, iron, and manganese by the UF-KA-IE was 95.9%, 99.9%, and 72.5%

Mata air pegunungan merupakan sumber air yang digunakan oleh masyarakatyang umumnya tinggal di dataran tinggi, termasuk di Desa Terobosan, Kota Cimahi. Namunsumber mata air tersebut belum layak untuk dikonsumsi secara langsung karena kandunganpartikulat dan pathogen yang berbahaya bagi kesehatan. Kegiatan pengabdian masyarakatini fokus pada penyediaan air siap minum dari mata air di Desa Terobosan menggunakanteknologi ultrafiltrasi (UF). Mata air yang difiltrasi dengan membrane UF memenuhistandard sebagai air siap minum sesuai dengan Peraturan Menteri Kesehatan RepublikIndonesia No.492/MENKES/PER/IV/2010 tentang Kualitas Air minum. Untuk keberlanjutankegiatan, instalasi UF membran untuk penyediaan air minum tidak hanya dilaksanakan diDesa Terobosan saja namun juga di daerah lainnya di Kota Cimahi.
