Kajian Filtrasi Air Limbah Sungai Ciliwung Mengunakan Membran Selulosa Asetat dan Teflon

Abstract

On this research would do waste water filtration by using membrane of teflon and cellulose acetate. The method was used is a dead end for teflon and for cellulose acetate membrane method will use dead-end and cross-flow. It also would have done three variations of pressure for each treatment. From the results of research on deadend with PTFE membrane needs to be greater pressure than cellulose acetate. For a dead-end debit highest on PTFE pressure 5.8 psi with a value of 0,604 ml/minute and flux of 0.625 cm/min. For a dead-end with cellulose acetate membrane meliki highest debit on the pressure of 7.5 psi with the value 0.41 ml/minute and fluksnya 0.06 cm/min. whereas cross-flow membrane cellulose acetate produces the highest debit 0.42 ml/min and the highest flux 0.021 cm/min at a pressure of 7.5 psi. for the lowest value of turbidity characteristics possessed by the process of cross-flow at pressure 5 psi with a value of 0.22 NTU. Most neutral acidity was owned by the process deadend with cellulose acetate membrane pressure 2.5 psi. type the lowest value for the masses was a product of cross-flow with a pressure of 5 psi with a value of 1,02606 gr/cm3. Total solids remaining the lowest also owned by the product of cross-flow filtration pressure 5 psi. for the lowest value of viscosity obtained on the process dead-end with teflon membrane on the pressure of 5.8 psi.
