A large percentage of wastewater treatment plants (WWTPs) in Europe and in the rest of the world are still being operated below optimum achievable performance. This underperformance becomes apparent in the form of treated water discharges that are not compliant with water quality standards as well as low efficiencies in terms of energy consumption. In this context, the art-ICA (advanced real time – Instrumentation, Control and Automation) controllers are a novel advanced control solution for biological nutrient removal WWTPs that, when applied, immediately lead to significant improvements in these systems in terms of the quality of the treated water combined with appreciable savings in electricity.Although the technical feasibility of the art-ICA controllers has already been proven in two real Spanish plants (the Galindo WWTP, 1.5 MPE –Population Equivalent–, and the Mekolalde WWTP, 50 kPE), two major factors have kept the art-ICA controllers from being accepted in the market more quickly:
- The wastewater sector is, in general, reluctant to incorporate new solutions that are not fully consolidated in the market;
- The investment costs associated with the art-ICA controllers are still considered relatively expensive for wastewater operators.
In this page:
The number of European WWTPs in which the art-ICA controllers might be installed today is above 10000, which amounts to a total pollution load above 400 MPE. We expect that by 2021 the art-ICA controllers will be working in about 78 wastewater treatment facilities. If such estimates come true this product will lead to the following: energy savings of above 4 GWh/year, reductions in CO2 emissions by around 1160 t CO2/year, and reductions of nitrogen in water discharge by around 1000 t N/year.
The environmental benefits of the art-ICA controllers lie in their ability to noticeably improve the performance of current wastewater treatment processes. This performance will become apparent in the form of:
- Lower levels of pollutants in treated effluents
- Reductions in electricity consumption
