Nutrient Removal in the Treatment of Batik Wastewater using Bench-Scale Sequencing Batch Reactor (SBR) System

Batik is one of the oldest cottage textile industries in Malaysia. Kilang Batik
Fauzi, a local batik factory located in Chemor, Perak Darul Ridzuan, Malaysia, has
been operating for batik production and served as a tourist attraction for almost two
decades. The batik factory discharges the batik wastewater produced during the batik
process, includes soaking, boiling, and rinsing steps into the ground without proper
treatment. The lack of appropriate treatment for batik wastewater has always been a
significant problem developed by most batik factories. Kilang Batik Fauzi discharges
its effluents into the environment without proper treatment, providing negative
impacts on the environment and ecosystems due to toxicity and non-biodegradability
of chemicals, and dyes present in batik discharges.
