Mitsubishi Electric Corporation developed “aeration control technology” to suppress excessive aeration to the biological reactor.

This technology utilizes the company’s Maisart® AI technology to accurately predict the quality of water (ammonia concentration) flowing into biological reactors that will undergo oxidative treatment required for wastewater treatment up to several hours ahead, thereby suppressing excessive aeration of biological reactors.

In the simulation using actual sewage treatment plant data, the aeration volume was reduced by about 10% compared to the conventional system while maintaining the quality of the treated water by controlling each section.

In addition, the company said it will contribute to reducing the power consumption of sewage treatment plants, which is currently consuming approximately 0.7% of Japan’s annual power consumption (approximately 7 billion kWh).

At present, the effectiveness of this technology is being confirmed with the cooperation of domestic sewage treatment plants.

In the future, the company intends to verify the stability and effect of control in actual operation and commercialize it as an operation monitoring and control system for domestic and overseas sewage treatment plants in fiscal 2020.
