Resource Recovery Potential of Wastewater Treatment Plants in Yogyakarta

Abstract

Wastewater contains water, nutrients, and energy resources, which can be recovered for human activities. Product from wastewater is one of the solutions to provide energy and food security amidst the looming energy and fertilizer crisis. Unfortunately, wastewater treatment plants in developing countries are often designed not to accommodate the concept of resource recovery. Currently, there is a real lack of feasibility analysis of upgrading existing wastewater treatment plants to accommodate the concept of resource recovery. Therefore, this study aims to determine the resource recovery potential in existing wastewater treatment plants in Yogyakarta and identify their limitations for resource recovery. Two wastewater treatment plants in Yogyakarta were assessed, one with anaerobic treatment, the other with stabilization ponds. The feasibility is assessed by the parameter of wastewater flow, organics, nutrients, and microbiology compounds. The findings of this study will be beneficial for a regional management standpoint to consider the most suitable strategy for wastewater management in Yogyakarta.

An insight into potential phosphate bioremediation and renewable energy from agricultural waste via integrated wastewater treatment systems in Indonesia

“…However, the method is sensitive to factors like temperature and pH and requires long treatment times as well as large land areas, and these systems produce unpleasant odorous biogas (Ahmad et al 2003, Azmi andYunos 2014). Marleni et al (2020) have highlighted the widespread use of untreated wastewater in developing countries. Globally, approximately 20 million hectares of land are irrigated using untreated wastewater, posing health risks to farmers, vendors, consumers, and contributing significantly to the global burden of diseases associated with excreta-related illnesses.…”

“…The synergistic interaction of these pathways enhances the overall efficiency of reducing phosphorus concentrations in wastewater. To remove P from wastewater, it's essential to harvest and extract these solid forms (Marleni et al 2020). Nonetheless, a significant number of WSPs lack specialized harvesting mechanisms and instead rely on natural sedimentation within the ponds to separate and remove P solids.…”

Evaluasi Karakteristik Air Limbah Hasil Pengolahan Waste Stabilazion Pond di Kota Jakarta

“…Jika pengurangan patogen lebih lanjut diperlukan, kolam pematangan akan diperkenalkan untuk memberikan pengobatan tersier. WSP sangat banyak digunakan untuk komunitas pedesaan kecil tetapi sistem besar ada di Kota Jakarta dan beberapa daerah di Indoensia (Azizah, Slamet and Yuniarto, 2017;Solikhin, 2018;Marleni, Putri and Istiqomah, 2020;Darwin et al, 2021;Di, Musi and Mura, 2021;Handoko and Pendahuluan, 2021). Pengolahan air limbah oleh WSP telah dianggap sebagai cara yang ideal untuk menggunakan proses alami untuk meningkatkan limbah air limbah.…”
