Abstract

The methods of microbial cells preservation were already known by liquid drying, freeze-drying, and freezing. Those methods could preserve bacteria cells in a long period of time but its survivability was relatively low and used relatively high energy during preservation. Immobilization was known as entrapping, attaching or encapsulating bacterial cells in a suitable matrix. This research was conducted to know the suitability of zeolite as immobilization carrier and also as preservation matrix of two halophilic archaea Haloferax chudinovii and Haloferax lucentense. Variable of this research was the type of the carrier which was raw zeolite, 110oC and 300oC heat-activated zeolite carrier, parameters measured in this study was physical and chemical of zeolite such as chemical content, Si/Al ratio, surface area and pore volume, and biochemical assay, bacterial cells numbers after immobilization and bacterial cells after preservation as bacterial response to the immobilization and preservation. Heat activation was significantly affecting the chemical composition, carrier surface area, and pore volume. Highest surface area, pore volume, and Si/Al ratio were obtained in 110oC pretreated zeolite followed by 300oC pretreated zeolite. The bacterial cells obtained after immobilization process was 1,8x107 cfu/g, 3,0 x 107 cfu/g, and 2,1x107 for raw zeolite, 110oC pretreated zeolite and 300oC zeolite respectively. After 4 months preservation, the slight reduction of the bacterial cells was observed. Immobilization halophilic archaeae using zeolite as carrier was proven as low cost and effective preservation method due to relatively simple process and unspecific preservation temperature requirements.

Abstract

Pengendapan merupakan suatu cara yang paling sederhana, murah, dan banyak digunakan dalam proses pengolahan air limbah. Kinerja dari suatu design bak pengendap sangat spesifik untuk setiap jenis limbah, oleh sebab itu jika suatu peralatan sedimentasi dirancang tanpa suatu eksperimen, kinerja yang dihasilkan sering tidak memuaskan. Metode grafis merupakan salah satu cara dalam menentukan desain bak sedimentasi. Metode grafis dapat menghasilkan suatu desain bak pengendap yang tepat sebagaimana sistem komputasi karena ditentukan dengan eksperimen namun dengan cara yang lebih sederhana dan biaya yang murah. Tujuan dari penelitian ini adalah merancang bak pengendap air limbah dari proses lumpur aktif dengan metode grafis disesuaikan dengan kriteria dasar-dasar perencanaan bak pengendap. Penelitian secara laboratoris dilakukan melalui pengamatan proses pengendapan dalam tabung kaca tinggi 150 cm dan luas penampang 100 cm2. Parameter yang diamati adalah tinggi endapan vs waktu pengendapan. Dengan perhitungan secara grafis didapatkan hasil sebagai berikut. Untuk mengendapkan lumpur dengan kandungan TSS awal 4325 mg/L menjadi 18.000 mg/L dengan debit 300 m3/hari diperlukan HRT (Hydraulic Retention Time) 1,87 jam, Luas area pengendapan 20,83 m2, Volume bak pengendap 31,24 m3. Perkiraan lumpur yang dihasilkan adalah sebesar 98,61 kg TSS/hari.

Abstract

Biogas is a renewable energy sources that could replace the role of fossil fuel. Biogas could be produced from biomass or agro-industrial wastewater. Sugarcane vinasse has potential of biogas production due to its high BOD concentration (10–65 g BOD/l). However, the biogas production from sugarcane vinasse has several drawbacks that hinders the maximum biogas yield, such as: acidic pH (pH 3.5 – 5.0), high temperature (80–90°C) and high concentration of sulfuric acid (> 150 mg/L). Theoretically, the methane potential per gram COD is 0.35 L/gr COD, containing of 60% methane. However, up to date, the maximum biogas production from vinasse was less then its theoretical value. To get the full potential of biogas production from vinasse wastewater as well as to reduce the capital cost for full scale application, combination of suitable pre-treatment, selected microorganisms and bioreactor design-configuration are the most important parameters to be considered. This paper aims to explore the potential of sugarcane vinasse to produce biogas, by elaborating the aforementioned key parameters. In this review the basic characteristic and the potency of sugarcane vinasse wastewater will be elaborated.  Furthermore, the effect of key parameters such as pH, temperature, and organic load to biogas production will also be discussed. The biogas technology will also be explored. Lastly, conclusion will be determined
