Penelitian ini bertujuan untuk memanfaatkan adsorben sebagai pengolahan awal sebelum proses ultrafiltrasi untuk pengolahan air sumur bor menjadi air layak konsumsi. Air umpan yang digunakan berasal dari sumur bor yang berada di areal Fakultas Teknik Universitas Sriwijaya Indralaya. Dua jenis adsorben yang digunakan adalah fly-ash dan zeolit dengan ukuran partikel masing-masing 20 mesh. Masing-masing adsorben ditempatkan dalam tabung FRP (Fiberglass Reinforced Plastic) yang dikombinasikan dengan membran UF (ultrafiltrasi) komersial tipe HM90UF (50,000-150000 Dalton). Variabel proses yang diteliti adalah waktu operasi mulai dari 15 sampai 90 menit laju alir air umpan menuju membran ultrafiltrasi yang diatur dari 4, 6 dan 8 L/menit. Parameter kualitas air yang menjadi fokus adalah pH, turbiditi, kadar nitrat, besi, dan mangan serta bakteri e-coli dan coliform. Pengukuran parameter analisis air dilakukan menurut Standar Nasional Indonesia (SNI), kandungan bakteri menurut metode APHA dan kadar ion logam menggunakan AAS (atomic absorption spectroscopy). Hasil yang diperoleh menunjukan bahwa kombinasi fly-ash dan ultrafiltrasi dapat meningkatkan pH air sumur bor dari 5,43 menjadi 7,0-8,1 dengan persentase penurunan turbiditi mencapai 99,48% sedangkan kombinasi zeolit dengan ultrafiltrasi dapat meningkatkan pH sampel menjadi 7,1 sampai 7,3 dengan penurunan turbiditi sebesar 99,71%. Air yang dihasilkan memenuhi syarat air bersih bahkan air minum karena bebas bakteri e-coli dan coliform. Penggunaan adsorben sebelum membran ultrafiltrasi dapat meningkatkan kualitas air sumur bor sehingga menjadi memenuhi syarat air bersih.

The purpose of this research is to investigate the performance of bentonite,hybrid of ultra-filtration and reverse osmosis (UF-RO) in improving the quality of liquid waste produced by pulp industry. The parameter used in this research is pH, turbidity, and Chemical Oxygen Demand (COD). The variable examined is operating time and feed water flow rate. The results show that the hybrid of UF-RO is able to produce permeates with optimum pH of 7,23 at 60 minutes operating time and reduce the turbidity almost 99% of the COD to 18 mg. L-1. It is suggested that the Bentonite and hybrid of UF/RO can be applied in the treatment of pulp and paper industries.

Hybrid UF – RO membrane technology is one of the new technologies of separation wastewater from the rubber industry to decrease turbidity and heavy metal contents such as iron and zinc. This technology is being used to replace the conventional installation process of wastewater treatment. Processing wastewater treatment from the rubber industry with the hybrid UF – RO membrane can produce permeate with quality standards, making it possible to be recycled as domestic water for water process in the industry. The technology of wastewater treatment from the rubber industry in this experiment involved the pre-treatment stage, using sand filter and adsorption using calcium carbide residue. The operating variables by flow rate into the UF and RO were 7 and 14 L.Min-1 and operation time were 15 to 90 minutes. The results of this study showed that the percentage reduced were 62.73% for turbidity, 83.28% for iron and 88.89% for zinc, respectively. Finally, it can be concluded that calcium carbide residue was potential to reduced turbidity and heavy metals such as iron and zinc from rubber industry wastewater.

The study aims to utilize Hybrid Membrane Technology (UF-RO) in reducing turbidity, iron and zinc in the liquid waste of the rubber industry. The pre-treatment process used was filtration and adsorption. The filtration process used filter columns containing silica sand and activated carbon, while the adsorption process used an adsorbent column containing bentonite. After the pre-treatment process, it was continued with the application Hybrid Membrane (UF-RO). The variables of the study were operation time of 15 to 90 minutes and flow rates of 7 and 14 L/min. The results showed that the optimum removal percentage of iron and zinc in the Reverse Osmosis Membrane was 84.86% and 96.29% at the feed flow rate of 14 L/min. The optimum removal percentage turbidity of 99.70% was achieved at the feed flow rate of 7 L/min in the Reverse Osmosis Membrane. Finally, rubber industry wastewater treatment using Hybrid Membrane (UF-RO) was able to reduce turbidity, iron and zinc content, and the results were accordanced with the quality standards regarding Water Quality.

This research was conducted to treat rubber industry wastewater by using fly-ash as an adsorbent and hybrid membrane UF-RO to produce clean water. In this research was analyzed the effect of flow rate of wastewater treatment to remove turbidity, zinc, and iron. The applied flow rate of membrane separation was of 7 L/min and 14 L/min and the operation time was of 90 min respectively. The rejection concentration of turbidity, zinc, and iron decreased with increasing the flow rate at adsorbent fly-ash. Whereas at the hybrid membrane UF-RO, the rejection concentration of turbidity, zinc, and iron increased with increasing the flow rate. The maximum rejection of turbidity was 24.26%, 95%, and 67.89% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of zinc was 91.67%, 59.70%, and 14.81% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of iron was 62.24% and 21.62% for adsorbent fly-ash, UF membrane respectively. The pollutants concentration in the permeate was met the quality standards of the Indonesian health department through the decision of the Minister of Health number 907 of 2002 concerning supervision of the quality of drinking water.
