Batik waste can increase water characteristics, such as turbidity, colorand total suspended solids (TSS). Thus, an efficient technique for separatingBatik from the liquid to decrease these characteristics is needed. The aim ofthe current study was to understand the results of flotation using electrolysisand to investigate the bubble characteristics that influence the results of theflotation of Batik waste. Flotation studies have been conducted usingelectrolysis to produce bubbles to separate batik synthetic dye from theliquid. Research conducted with 316L stainless steel electrodes, inside a 100cm tall acrylic pipe with an inner diameter of 8.4 cm and a voltage variationof 10, 15 and 20 V. Batik waste was mixed with distilled water. Commercial alumpowder [aluminum sulfate, Al2(SO4)3.14H2O,that is 17% Al2O3] as the reagent was added to coagulateBatik waste in a ratio of 1 gram per 10 ml of Batik waste. The results showedthat flotation of Batik waste can be used to separate Batik waste with theaddition of alum. Alum was shown to be capable of acting as a collector in thistype of waste separation. The results showed that flotation using electrolysiscould be an effective method for reducing turbidity, color and TSS. |
