Abstract

The objective of the research was to analyze the wastewater of Sanglah General Hospital Centre (RSUP Sanglah), Denpasar Bali Indonesia using Biodetox technology and to study the responses of Chinese cabbage (Brassica juncea L.) to the product. The research was conducted from 15 May 2009 to 15 June 2012. Results of the research indicated that the technology using 7.2 hours day-1 aeration could reduce Biological Oxygen Demand (BOD) level to 88%, but increased the Food/Microorganism (F/M) ratio to 13.94 g/BOD/day/g/Mixed Liquid Suspended Solids (MLSS), shortened sludge age to 22.71 hours, lowered sludge recirculation to 23.25%, decreased pollutant levels to 0.6% MLSS and 78% TSS. Those results had met the quality standard for wastewater processing technology and for irrigation water respectively of Department of Health (Permenkes RI No. 416/MENKES/PER/IX/1990) and Department of Environment (Kepmen KLH No.02/MENKLH/I/1988) of Republic Indonesia. The characteristics of the wastewater (containing 1.97% N, 0.78% P, 0.33% S, 0.48% K, 0.19% Mg, 0.96 mg l-1 Fe, 0.08 mg l-1 Al, 0.11 mg l-1 Mn, 0.19 mg l-1 Mg and 0.22 mg l-1 Mo), had also met the quality standard for fertilizer materials (Hammer, 2001). The products of the technology have been proven to be safely used as fertilizer materials as indicated by no heavy metals contained and significantly 19.9% and 17.3% higher leaf and plant total fresh weights of Chinese cabbage, respectively compared to commercial Biosugih and Hyponex fertilizers at the rate of 15 g product pot-1.
