BioResources and Technology Division (BRT) junior researcher and PhD student Lydia Mawar Ningsih and BRT Director Assoc Prof. Dr. Hynek Roubík recently published an article!
The results of this study demonstrate that the use of simple biofilter technology in an Anaerobic Baffled Reactor (ABR) has a positive impact on the quality of biogas effluent. Conducted on a pilot scale, the ABR had a capacity of 0.927 m3. The study utilized tofu wastewater sourced from small-scale tofu industries in Indonesia, where the availability of wastewater is abundant due to tofu being a staple food and many tofu production operations being at the home industry level.
The integration of biofilters improved the nutrient content of the biogas effluent, transforming it into an organic liquid fertilizer. This fertilizer proves beneficial for farmers, as it can be applied to agricultural land. The best results were achieved by mixing biogas effluent with AB nutrient (a commercial nutrient), which met the organic fertilizer standards outlined in the Indonesian Ministry of Agriculture Regulation PERMENTAN No. 70/permentan/SR.140/10/2011.
Furthermore, the biofilters not only enhanced the quality of biogas effluent but also increased methane concentration, making it a viable energy source to replace non-renewable energy in industrial activities.
The use of simple biofilter technology offers significant environmental and economic benefits, making it highly recommended for industries seeking sustainable wastewater management solutions.
