Global warming-related technology
To help prevent global warming, METAWATER is proactively engaged in the development of technologies to decrease the emissions of greenhouse gases, energy saving technologies and also energy regeneration technologies.
The nitrous oxide (N2O) emitted from wastewater sludge incinerators is said to have a greenhouse effect which is as much as 310 times that of CO2, a typical greenhouse gas. Because a high concentration of N2O is generated while incinerating wastewater sludge, reduction of N2O from wastewater sludge incinerators offers a significant advantage in helping to prevent global warming.
Wastewater sludge is a sustainable and renewable resource. We will emphasize the importance of "resource recovery" from the wastewater sludge as a new role of sewage in our society and, at the same time, we will generate a new energy (bio-mass energy).
Our target is to save energy and optimize the entire plant by controlling non-linear behaviors based on multi-variate data (measurement value, control target) and making improvements in rapid response and convergence, while they were infeasible with conventional PID control.
