FABRICATION OF ULTRAFILTRATION MEMBRANE USING ADDTIVE TO EXTRACT HORMONE FROM POULTRY WASTEWATER

Abstract

Steroidal hormones such as 17β-estradiol produced by humans and animals are regularly being released into the environment in their active forms. As the demand of chicken is increasing nowadays, there is a need to evaluate and assess the concentration of hormones in the poultry wastewater. In this study, a simple ultrafiltration membrane was fabricated to extract the hormones in the poultry wastewater from Kuala Garing, Rawang Selangor. Self-doped, sulfonated forms of polyaniline-polyvinylpyrrolidone (PANi-PVP) are blend into polysulfone (PSf) and N- methyl-2-pyrolidone (NMP) ultrafiltration membranes to enhance the hydrophilicity and fouling resistance. The Sulfonated Polyaniline-Polyvinylpyrrolidone (SPANi-PVP) polymer was dedoped at varying concentrations of PANi-PVP additive. Their concentrations vary from 0.5% of PANi-PVP, 1% PANi-PVP, 1.5% PANi-PVP, 2% PANi-PVP to 2.5% PANi-PVP. These newly fabricated ultrafiltration flat sheet membranes which containing increasing amounts of PANi-PVP was than tested for tap water permeability and hormone 17β-estradiol filtration from the poultry wastewater. The result of the study justify that, as the PANi-PVP concentration increased, the rejection of solute increased while the permeate flux decreased. The highest rejection of 17β- estradiol (E2) from the poultry wastewater was 92.5% with the mass of 17β- estradiol retained is 0.37ng/L. This was obtained from the highest amount of PANi-PVP concentration in the membrane which is 2.5wt%. However, the permeate flux for this 2.5wt% of PANi-PVP membrane was to slow compared to other membranes that has lower amount of PANi-PVP concentration. This is due to the higher the PANi-PVP concentration, a thicker and denser membrane skin layer was formed.
