Abstract

Produksi Kelapa sawit menghasilkan limbah cair yang dikenal dengan Palm Oil Mill Effluent (POME). Proses produksi kelapa sawit pada umumnya menggunakan penambahan air selama proses ekstraksi minyak sawit mentah (CPO) dari tandan buah segar (TBS) dan menyebabkan jumlah air limbah yang dihasilkan cukup besar. limbah cair POME memiliki kandungan BOD5 10.000 mg/L; COD 22.115 mg/L; TSS sebesar 4.260 mg/L, kandungan minyak dan lemal sebesar 260 mg/L dan memiliki Ph asam sekitar 4,6. Berbagai metode pengolahan limbah POME telah diteliti seperti pengolahan biologis, teknologi membran, koagulasi, flokulasi dan elektrokoagulasi dan kombinasi pengolahan fisik biologi salah satunya teknologi Sequencing Batch Reactor. Membran dengan bahan anorganik seperti zeolit dan silika memiliki beberapa keuntungan dalam aplikasi pengolahan diantara distribusi ukuran pori kecil sehingga meningkatkan selektifitas. Penelitian ini difokuskan pada pengujian kinerja membran zeolit silika untuk mengukur nilai fluks dan nilai rejeksi COD  pada limbah cair kelapa sawit.. Variabel penelitian yang digunakan variasi kecepatan centrifuge 200 rpm dan 600 rpm. Reaktor yang digunakan adalah reaktor cross flow. Pengujian reaktor dilakukan selama 100 menit dan permeate diambil setiap 20 menit. Berdasarkan hasil penelitian.

Abstract

Filtration membranes using natural zeolite and silica sand materials can be a promising alternative filtration technology for processing palm oil industrial wastewater. Palm oil wastewater is waste produced by the palm oil industry that contains high TSS content and will pollute the aquatic environment if not optimally treated. This study aims to determine the effectiveness of TSS removal in palm oil wastewater using zeolite-silica membranes. Membrane performance was evaluated through filtration tests using a cross-flow reactor for 100 minutes, with permeate samples taken every 20 minutes at a pressure of 5 bar. Membrane performance was assessed based on membrane flux values and TSS rejection rates. The results showed that the initial TSS characteristics of palm oil wastewater at a 100% concentration were 3,180 mg/L, while at a 50% concentration, they were 1,120 mg/L. The highest TSS removal efficiency was achieved at a 100% wastewater concentration, reached 92.1%
