INFLUENCE OF TEXTILE LIQUID WASTE TREATMENT METHODS ON CONCENTRATIONS OF ADSORBEN BOTTOM ASH

Abstract

Liquid waste treatment must be carried out by every textile industry before being discharged into the environment, this needs to be done so as not to cause a bad impact on water resources or prevent environmental damage. This research is an experimental wastewater treatment by utilizing solid waste from coal, namely bottom ash with a comparison of two methods, which include filtration and batch. This experiment aims to become an alternative for wastewater treatment that can be used to reduce water pollution levels in the environment by utilizing waste water. This experiment was conducted by comparing two methods, namely the filtration method in which the waste flows through a cylindrical glass column in which there is foam, gravel, and bottom ash, while the batch method is to ensure even contact between the adsorbent and the adsorbate. Parameter evaluation carried out are Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and  ​​Total Suspended Solid (TSS). Based on the results of research and testing conducted on waste treatment using bottom ash is proven to be the best results on the filtration method. The COD parameters for the Filtration method and the Batch method for COD results from the Filtration method are 268.8 mg O₂/L while the COD produced by the Batch method is 576 mg O₂/L. In this TSS test the result of the Filtration method is 20 mg/L while the Batch method is 200 mg/L. For BOD testing, the results of the Filtration method are still better than the Batch method. The result of the Filtration method is 104 mg O₂/L while the Batch method is 134 mg O₂/L.
