Revolutionizing Swine Farming: Cost-Effective Wastewater Treatment & Nutrient Recovery Innovation
Channel: Okinawa Institute of Science and Technology (OIST)
Date: 2024-01-16

A group of OIST researchers, supported by the OIST Proof of Concept program, are developing on a cost-effective and low-maintenance scale-up system for advanced wastewater treatment and nutrient recovery on swine farms. Pig farming wastewater poses challenges due to its volume and high concentrations of organic matter, phosphorus, and nitrogen. Their innovative two-tank system, utilizing anaerobic microorganisms with electrodes, simultaneously treats organic matter and nitrate. After successful demonstrations and three years of operation on a 65-liter scale, they have collaborated for a 525-liter scale-up with industry and environmental centers. This eco-friendly approach not only reduces running costs by 20-50% but also ensures compliance with stricter discharge regulations.
