Abstract

Air gambut adalah sumber air alternatif untuk menyediakan air bersih di Pulau Kalimantan. Air gambut harus dijernihkan karena berwarna (merah kecoklatan), memiliki pH rendah (3-5), dan banyak mengandung zat organik. Penelitian ini mengamati efek berbagai jenis elektroda dan waktu kontak pada prosedur elektrokoagulasi untuk mengetahui seberapa efektif elektrokoagulasi dalam penjernihan air gambut. Ini karena elektrokoagulasi dapat digunakan untuk mengurangi kadar logam, keasaman, dan kandungan organik dalam air gambut. . Penelitian ini menggunakan berbagai jenis plat elektroda aluminium (Al)-aluminium (Al) dan aluminium (Al)-karbon (C), serta interval waktu kontak 45, 90 dan 120 menit. Parameter pengamatan yaitu keasaman (pH), mangan (Mn), BOD, dan COD. Dalam penelitian ini, jenis plat elektroda yang digunakan serta waktu kontak yang digunakan dipengaruhi oleh arus listrik  yang diberikan. Dengan waktu kontak 45 menit, jenis plat Al-C adalah yang terbaik untuk menjernihkan air gambut dengan efisiensi 99,99%. Parameter penyisihan mangan (Mn) turun dari 0,17 mg/L menjadi 0,03 mg/L, dan efisiensi kebutuhan oksigen biologi (BOD) mampu mencapai  99,99%.

Abstract

High levels of phosphates and surfactants will cause rapid organism growth, which can lead to dissolved oxygen depletion, reduce water environment quality, and be harmful to biota. One of the treatments that can be performed to process laundry wastewater is the adsorption process. The wastewater treatment conducted in this study uses adsorbents from durian peels and PDAM sludge. Research about the adsorbents is related to the carbonization temperature, chemical activator, stirring speed, and contact time of the adsorbents with the laundry wastewater. This study aims to determine the effectiveness of durian peel adsorbent, PDAM sludge, and a mixture both of adsorbents . The adsorbents that have been made were tested for characteristics such as moisture content, ash content, volatile matter, pure carbon, iodine absorption, surface area, and specific pores. The variations used were contact times of 15, 30, 45, and 60 minutes and types of adsorbents: durian peel, PDAM sludge, and a mixture both of adsorbents. The results showed that durian skin and PDAM sludge adsorbents meet the SNI 06-3730-1995 adsorbent characteristics, except that iodine absorption did not meet. The most effective contact time of durian peel adsorbent in reducing phosphate and surfactant levels was 15 minutes. The most effective contact time of PDAM sludge adsorbent and a mixture of the two adsorbent in reducing phosphate levels is 15 minutes, and for surfactant, it is 45 minutes. Further research that can be done is to make adsorbents at different temperatures from this study.
