Software-Defined Decentralized Domestic Wastewater Treatment: 1st Milestone

Water scarcity has been intensified globally due to the rapid growth of economic and population. Wastewater treatment and recycling is one of the most feasible strategies for meeting the ever-increasing water usage. However, conventional centralized wastewater treatment plants are being stretched to their limits with the emerging urban structures. To mitigate this situation, this paper proposes a decentralized treatment solution for domestic wastewater leveraging the recent advancements in instrumentation, automation, and information technologies. In particular, a 60-ton adjustable secondary wastewater treatment facility has been designed as a foundation, upon which in-situ monitoring, software-centric automation system, and industrial edge-cloud computing platform have been deployed to form a holistic solution. The resultant facility has been consecutively and successfully operating onsite to date.
