Biogas Production from Pineapple Industry Wastewater Using UASB with Microbial Immobilization from Shrimp Pond Sludge
Main Article Content
Abstract
Agricultural industrial wastewater contains high organic loading from a production process, which is the main problem of environmental pollution in case it leaks to an open landfill or water resources. This research aims to propose a method of reducing organic content and converting wastewater into renewable energy. The Upflow Anaerobic Sludge Blanket (UASB) system was designed and established for biogas production and biological wastewater treatment from the agricultural industry waste. A suitable condition for biogas production from pineapple industry wastewater was performed and investigated and then applied in the designed UASB system. The result showed that the fermentation condition for submerging CAC (Cray/Activated Carbon) with microbial immobilization from shrimp pond sludge enhanced biogas production to 2.6 times and treated wastewater at the same time. The designed system reduced the COD value of wastewater and also produced biogas in a satisfactory way with approximately 24.74% of methane. Therefore, the application of the designed UASB system reveals the possibility and promising way of biogas production from pineapple wastewater.
