FENOMENA FOULING MODEL SUSPENDED SOLIDS PADA MEMBRAN MIKROFILTRASI

Abstract

ABSTRAK Penurunan penetrasi cahaya matahari dan suhu, serta peningkatan akumulasi logam berat terjadi signifikan akibat hadirnya padatan tersuspensi. Metode sintetis padatan tersuspensi dilakukan guna efisiensi pengolahan air, dikarenakan kuantitas dan kualitas air limbah yang semakin buruk. Permasalahan akan timbul ketika dibutuhkannya sintetis pada kondisi khusus, karena tingkat representatif sintetis sangat dipertimbangkan. Dari penelitian ini, dihasilkan rekomendasi sintetis padatan tersuspensi, berdasarkan uji selektivitas (ukuran, bentuk dan sifat) terhadap pengaruh variasi pH dan konsentrasi. Dengan metode crossflow pada membran mikrofiltrasi, penelitian ini dapat mengetahui seberapa besar flux, rejeksi, feed removal, serta mengilustrasikan fouling yang terjadi, dengan uji ukuran partikel (Particle Size Analyser), luas permukaan (Surface Area Analyser) dan morfologi bahan (Scanning Electron Microscopy) sebagai data pendukung. Kata kunci: sintetis padatan tersuspensi, crossflow, fouling ABSTRACT Decrease of sunlight penetration and temperature also an increase of heavy metals accumulation occurs significantly due to the presence of suspended solids. The suspended solids synthesis method is carried out for water treatment efficiency, because the quantity and quality of wastewater are getting worse. Problems will arise when the need for synthetics is in special condition, due to the synthetic representative level is highly considered. From this research, recommendation for the synthesis of suspended solids were produced, based on selectivity test (size, shape, and properties) of the effect of pH and concentration variation. With cross flow method on microfiltration membrane, this research can determine how much flux, rejection, feed removal, and illustrate fouling that occurs. By testing particle size, surface area and membrane morphology as supporting data. Keywords : suspended solids synthetic, crossflow, fouling
