Batik wastewater has large contributions to environmental pollution due to the usage
of dyes and effluent discharging without any treatment. This study aimed to develop
a low cost bio-filtration system for batik wastewater treatment. Magnesium oxide was
used for the treatment process while sponge, zeolite and rice husk were used as filter
media for the treatment process. FTIR and SEM were used to determine the
morphology and surface chemistry of zeolite and rice husk which acts as adsorbent in
this process. From the observation, pre-treatment and filtration process using the
developed system was able to reduce COD of batik wastewater from 38 mg/L to 11
mg/L (71% removal). TSS and turbidity were also successfully removed for almost
34% and 7%, respectively. The findings of this research can be a good fundamental
knowledge and platform for the development and improvement of the batik
wastewater treatment system in the future.
