Provides the most appropriate oxygen dynamic set point and N/DN strategy to optimize nitrogen removal performance with minimum energy cost.of nutrient levels is delivered at the lowest energy prices.
Provides the most appropriate oxygen dynamic set point to optimize organic matter removal with minimum energy cost,
Based on real-time oxygen demand, provides a strategy that guarantees oxygen levels applying dynamic pressure control, ensuring the maximum aeration system efficiency at a suitable MOV scenario.
Adjusts internal recirculation pumping according to nitrate levels, treated flow and retention in the anoxic chambers.
Optimizes sludge recirculation according to plant’s treatment flow and sludge settlement conditions.
Based on theoretical measurements, records information and feeds the other controls with the most appropriate energy consumption practice according to the energy tariff plan (cost kWh).
Tracking energy measurements, provides information to the other controls and determines specific process/equipment ratios that enables problem detection, breakdowns and deviations.
Adjusts coagulant dosage to the evolution of the orthophosphate concentration or total phosphate in the treatment- plant influent/effluent.
Ensures N-removal efficiency with optimal external carbon source dosing in WWTPs that shows limited denitrification capacity due to shortage of organic matter availability in influent wastewater (low COD/N ratio).
Adjusts dosage of an external source of nitrogen in WWTPs with an excessive COD/N ratio, which hinders cell synthesis due to lack of nutrients.
In order to widen the scope of the nitrogen removal control system, the homogenization tank operates as a time-of-use tariff, storing water when energy costs are more expensive and feeding it to the biological treatment system when the energy tariff is cheaper.
Based on nitrification performance and water temperature, the system adjusts the sludge waste flow (or gives recommendations) to operate the process at the minimum sludge age required for achieving the desired effluent quality levels.
Design and implementation of controls to meet the specific needs of each process.
Based on real-time monitoring of the main operating parameters (mass load, VFA/ALK ratio, biogas production, etc.), water treatment capacity is optimized and the reduction of organic matter and biogas production are maximized. Energy usage is minimized in the subsequent aerobic treatment. This control significantly increases process robustness and reliability.
Optimizes polymer dose in real time, stabilizing the thickening process, increasing solids capture while reducing chemical dosing costs.
Optimizes polymer dose in real time, increase solids capture while saving money on sludge disposal and polymer costs.
Based on biogas production, storage and kWh cost, defines the cogeneration engine operating strategy to maximize power generation and/or adapt it to plant consumption patterns.
