Regenerasi secara Kimia Membran Ultrafiltrasi Sistem Aliran Cross Flow pada Proses Penyaringan Air Terproduksi

Abstract

Produced water is water that obtained from the process of oil mining. Based on the characteristic that the produced water is classified as to the wastewater, required treatment before being discharged into water bodies. One of the alternative tech-nologies that can be used for produced water treatment is membrane technology.The main challenge in the use of membrane technology is fouling. This researchaims to study the trans-membrane pressure on flux, study the effectiveness andefficiency of NaOH and detergent in the regeneration process of ultrafiltrationmembranes on operation filtration of produced water. The study was conductedusing ultrafiltration membranes by feeding produced water. The method used is byvarying the operating pressure of 0.5 bar and 1 bar, variations in the concentrationof NaOH and Detergents 0.5%, 1% and 1,5%. Filtration process of produced waterlasted for 120 minutes and each leaching time is 30 minutes, the highest effective-ness rate of 30.55% obtained by using detergent 1.5%, the highest leaching effi-ciency based on flux recovery value is 69.66% and 30.55% for removal resistance,the highest flux value after chemical leaching obtained 0.8950 ml/menit.cm2 intrans-membrane pressure of 0.6 bar and the concentration of the detergent 1.5%.
