PENGARUH PENAMBAHAN GLUKOSA SEBAGAI CO-SUBSTRAT DALAM PENGOLAHAN LIMBAH MINYAK SOLAR MENGGUNAKAN SISTEM HIGH RATE ALGA REACTOR HRAR

ABSTRAK

Kandungan minyak dalam air limbah umumnya relatif sulit untuk diuraikan oleh mikroorganisme pada pengolahan air limbah secara biologis. Sistem alga dalam High Rate Alga Reactor HRAR telah banyak dikembangkan dan digunakan sebagai pengolah air limbah domestik dan industri. Aplikasi sistem alga dalam HRAR ini dicoba untuk diaplikasikan dalam pengolahan air limbah minyak solar. Penelitian dilakukan untuk mengkaji kemampuan HRAR dalam menurunkan kandungan minyak solar dengan penambahan glukosa sebagai co-substrate. Penambahan co-substrate diperkirakan dapat mendorong bakteri untuk memberikan suplai karbondioksida pada mikroalga. Penelitian ini dilaksanakan menggunakan 8 reaktor dengan variabel penelitian konsentrasi minyak solar dalam air limbah dan konsentrasi gula yang ditambahkan. Variasi gula yang ditambahkan adalah 5 gram 7 gram dan 10 gram ke dalam 18 Liter air pada reaktor. Variasi konsentrasi minyak solar yang ditambahankan ditentukan dari penelitian pendahuluan. Pada penelitian pendahuluan dilakukan penambahan minyak solar ke dalam reaktor berupa 4 variasi konsentrasi dan 1 reaktor kontrol. Dari variasi konsentrasi minyak solar tersebut digunakan 2 konsentrasi yang dapat ditoleransi oleh alga untuk digunakan dalam penelitian yaitu 381 ppm dan 830 ppm. Setiap dua hari sekali selama 14 hari akan diambil sampel untuk kemudian dianalisis masing-masing parameternya. Parameter yang dianalisis dalam penelitian ini adalah oil grease COD klorofil a DO pH temperatur dan MLSS.


ABSTRACT

Oil content in wastewater are generally difficult to be degradated by microorganism using biological waste water treatment.High Rate Algae Reactor HRAR has been developed and widely used as domestic and industrial wastewater treatment. Algae in HRAR system is attempted to be applied in wastewater treatment containing diesel oil. The research was conducted to assess HRAR ability on removing diesel oil by the addition of glucose as co-substrate. Addition of co-substrate is estimated to stimulate bacteria to provide carbondioxide for microalgae. This research was conducted using 8 reactors with concentration of diesel oil in wastewater and concentration of sugar added as variable. Variations of sugar added were 5 grams 7 grams and 10 grams into 18 Liters of water in the reactor. Variations of diesel oil concentration were noted from preliminary research. Preliminary research was conducted using 4 variations of diesel oil concentration and 1 control reactor. From the 4 types of concentration only 2 were used which can be tolerated by algae to be used in this research. The concentration of diesel oil were 381 ppm and 830 ppm. Each parameter were analyzed once every two days for 14 days. The parameters analyzed in this research was oil grease COD chlorophyll a DO pH temperature and MLSS.
