OPTIMALISASI HASIL FILTRASI CaCO3 MENGGUNAKAN ALAT PRESS FILTER PLATE AND FRAME DENGAN PENGARUH WAKTU FILTRASI (Optimization of CaCO3 Filtration Result using a Press Filter and Frame with the Influence of Filtration Time)

Abstract

Filtrasi adalah operasi dimana campuran yang heterogen antara fluida dan partikel-partikel padatan dipisahkan oleh media filter yang meloloskan fluida tetapi menahan partikel-partikel padatan. Pada penelitian ini kita melakukan filtrasi terhadap bahan CaCO3. Proses filtrasi tersebut menghasilkan filtrat dan cake CaCO3 dengan menggunakan alat press filter plate and frame, dengan menggunakan variable berubah yaitu bukaan valve dan lama waktu filtrasi.Dimana hasil densitas dan berat cake basah yang dihasilkan paling optimum pada kondisi bukaan valve ¼ dan lama waktu filtrasi 20 menit. Dengan berat cake kering 30,75 gram dan densitas 1,41 gr/ml. Kata Kunci : Filtrasi, CaCO3, Plate and frame filter ABSTRACT Filtration is an operation in which a heterogeneous mixture of fluid and solid particles is separated by a filter medium that passes fluid but holds solid particles. In this study we filtrate CaCO3 material. Where the filtration process produces filtrate and cake CaCO3 using press filter plate and frame, using variable changes, namely valve opening and filtration time. In the research experiments conducted produce different valve opening viscosity with the same time increasing and resulting in the weight of the dry cake is getting smaller. While research experiments with optimal openings and different lengths of time produce as much viscosity as decreasing and increasing weight of dry cake. Where the results of the viscosity and weight of the dry cake produced are the optimum at the valve opening conditions ¼ with wet cake weight value 30,75 gram and the filtration time is 20 minutes is density 1,41 gr/ml.
