Abstract

This study examined the removal of nitrate from wastewater using column adsorption method with variations in the ratio of biochar and polyurethane foam, as well as variations in flow rate. The results showed that the highest adsorption capacity was obtained at a flow rate of 30 mL/min compared to other flow rate variations. At that flow rate, the nitrate sorption capacity reached 4.10 mg/g with biochar, 0.20 mg/g using biochar : polyurethane foam (1 : 1) media, and 13.12 mg/g using biochar : polyurethane foam (2 : 1) media. The biochar : polyurethane foam (2 : 1) media showed the highest nitrate adsorption capacity, which was caused by an increase in the contact time of the flow in the media due to more polyurethane foam volume. This study concludes that sufficient contact time between the contaminant and the adsorption media in the column is a key factor for nitrate removal optimization in addition to the adsorbent material used.Keywords: Adsorption, Biochar, Polyurethane foam, Nitrate ABSTRAKPenelitian ini mengkaji penyisihan nitrat dari limbah cair menggunakan metode adsorpsi kolom dengan variasi rasio biochar dan busa poliuretan, serta variasi laju alir. Hasil penelitian menunjukkan kapasitas adsorpsi tertinggi diperoleh pada laju alir 30 mL/menit dibandingkan variasi laju alir lainnya. Pada laju alir tersebut, kapasitas sadorpsi nitrat mencapai 4,10 mg/g dengan biochar, 0,20 mg/g menggunakan media biochar : busa poliuretan (1 : 1), dan 13,12 mg/g menggunakan media biochar : busa poliuretan (2 : 1). Media biochar : busa poliuretan (2 : 1) menunjukkan kapasitas adsorpsi nitrat paling tinggi, yang disebabkan oleh peningkatan waktu kontak aliran dalam media akibat kandungan busa poliuretan yang lebih banyak. Penelitian ini menyimpulkan bahwa waktu kontak yang cukup antara kontaminan dan media adsorpsi dalam kolom merupakan faktor kunci untuk optimasi penyisihan nitrat selain material adsorben yang dipakai.Kata kunci: Adsorpsi, Biochar, Busa poliuretan, Nitrat

Abstract

This study evaluates the efficiency of water usage in the Department of Environmental Engineering at Universitas Andalas (Unand) by analyzing water consumption volume, identifying potential leaks, and comparing the findings with applicable standards for laboratories and offices. A 1.5-inch water meter was installed at the outlet of the rooftop reservoir on the 4th floor to measure water usage volume, and manual attendance devices were used to record the number of water users in the office and laboratory. Leakage testing was performed using the step test method, where water flow was stopped for 16 hours overnight to monitor changes in the water meter readings, with results indicating no leakage. The study found that the highest water consumption was 39.66 L/person/day in the laboratory and 55.06 L/person/day in the office. Water consumption in laboratories was found to be 100-200 L/person/day according to the standard, while water use in offices slightly exceeds the Indonesian National Standard (SNI) 03-7065-2005 of 50 L/person/day. The study recommends implementing water conservation technologies, such as automatic faucets and dual-flush toilet systems, to reduce water consumption and enhance water efficiency.
