Abstract

Limbah kulit kerang yang berada di pesisir Pantai Kejeran telah menjadi masalah ibu kota Surabaya. Lebih dari 3 ton limbah kulit kerang setiap minggunya dihasilkan dan dibuang di pinggir Pantai Kenjeran. Kulit kerang tersusun atas senyawa kalsium karbonat (CaCO3) sehingga kulit kerang dapat dimanfaatkan sebagai media pada anaerobic filter. Penelitian dilakukan dalam skala laboratorium menggunakan reaktor yang telah direncanakan. Penelitian ini menggunakan sistem kontinyu dengan aliran upflow. Variasi penelitian yang digunakan adalah variasi waktu detensi (Empty Bed Contact Time) dan variasi ketebalan media yang digunakan. Variasi waktu detensi yang digunakan adalah 24; 30 dan 36 jam. Sedangkan variasi ketebalan media yang digunakan adalah tebal media 55 ; 80 dan 122 cm. Penelitian dilakukan dengan mulainya proses seeding dan aklimatisasi yang berlangsung selama 10 hari hingga kondisi reaktor berada dalam kondisi steady state. Penelitian utama dilakukan selama 7 hari dengan menguji parameter COD, TSS dan BOD. Berdasarkan hasil penelitian diperoleh nilai removal untuk parameter COD dan BOD tertinggi adalah 80,6 dan 89,91 persen pada tebal media 122 cm dan HRT 36 jam. Sedangkan untuk parameter TSS, didapatkan hasil removal terbaik pada tebal media 80 cm dan HRT 24 jam dengan removal 91,76 persen. ================================================================================================ The clamshell waste on the coast of Kejeran Beach has become a problem for the capital city of Surabaya. More than 3 tons of clamshell waste is produced every week and is disposed on Kenjeran Beach. Clamshells are composed of calcium carbonate (CaCO3) compounds. According to that, clamshells can be used as a medium on anaerobic filters. The research was carried out on a laboratory scale using a planned reactor. This study uses a continuous system with upflow. Variations in the research used are variations in detention time (empty bed contact time) and variations in the thickness of the media. The detention time variation used is 24; 30 and 36 hours. Whereas the thickness of the media used is media thickness 55; 80 and 122 cm. The research was carried out by the seeding and acclimatization process which lasted for 10 days until the reactor conditions were in steady state. The main study was carried out for 7 days by testing the parameters COD, TSS and BOD. Based on the results of the study, the highest removal values for the COD and BOD parameters were 80,6 and 89,91 percent in 122 cm media thickness and 36 hours HRT. While for TSS parameters, the best removal results obtained on 80 cm media thickness and 24 hour HRT.
