Aplikasi Pengolahan Limbah Batik Menggunakan Membran Keramik Berbiaya Rendah pada Kolom Batch

Abstract

Batik is a characteristic of Indonesian culture which in the manufacturing process will produce waste as a residue from the colouring process. The waste still has a high colour content so if it is not processed further it will pollute the environment. This study aims to synthesize ceramic membranes from low-cost materials and apply the use of these membranes to treat batik waste in a batch column. The variable used in this study is the processing cycle, the results of the first processing are put back into the batch column for up to 3 iterations. The parameters tested were pH, turbidity and colour testing. The results showed that the ceramic membrane was able to treat batik wastewater with a maximum turbidity rejection % of 86.67 % and a maximum % rejection of 67.51 %. Low-cost ceramic membranes are effective for use as an alternative for batik waste treatment.
