FEASIBILITY STUDY ON SURFACTANTS REMOVAL FROM PERSONAL CARE PRODUCT WASTEWATER USING SINGLE-STAGE FOAM FRACTIONATION
Publication Date : 01/02/2017
This paper presents a feasibility study on pre-treatment of personal care products (PCP) industrial effluents. The study employed single-stage foam fractionation as pre-treatment method. Three synthetic waste streams: shampoo-with-silicon, sh(+si), shampoo-without-silicon, sh(-si), and hair dye (ec) were used in the study. Chemical oxygen demand (COD) and foam measurements were conducted on pre-treated samples to determine carbon and surfactant removal efficiencies, respectively. COD removal efficiency > 90% was achieved in all the three waste streams. However, foam removal efficiency > 90% was only achieved in shampoo-based waste streams at low air flow rates. Results obtained indicated that foam fractionation is effective in selective removal of surfactants from shampoo-based waste streams at airflow rate lower than 3 L/min.
