Batik textile production often lead to wastewater production during soaking, boiling and rinsing steps. These effluents have threatened aquatic organisms due to toxicities and non-degradability. A novel machinery has been invented to efficiently reduce the toxic wastewater produced by the Batik industry. Considering the chemical properties of batik effluents, an efficient and economical treatment process was established to treat batik wastewater containing not only high levels of Si and chemical oxygen demand (COD), but also potentially toxic heavy metals.
Effluents from the boiling and soaking steps in the batik process, was treated under acidic conditions. This process removed ~7895% of COD and ~4550% of Si, depending on the solution pH. In the second stage, heavy metals and almost 90% of the Si are removed from the liquid phase. During this step also, about 70% of COD was removed in the sludge. The sludge was composed mainly of silicate solids and wax with polymeric properties. The final step is to remove the remaining COD to < 50 mg/L.
