Smart Control for Biological Systems in Wastewater Treatment Plants (Carbon Source & Aeration)

The biological treatment system is the core of a wastewater treatment plant and a major consumer of energy and carbon sources. This solution provides collaborative intelligent control for aerobic aeration and anoxic carbon source dosing. Based on the influent pollution load, the system uses AI algorithms to simultaneously optimize oxygen supply and carbon source dosing. While ensuring effluent quality, it achieves precise aeration and precise carbon source utilization, driving the plant's operation from "extensive" to "refined" management.

We provide coordinated smart control for aerobic aeration and anoxic carbon source dosing. Based on influent pollution load, AI algorithms simultaneously optimize oxygen supply and carbon source dosing — achieving precise aeration and carbon source utilization while ensuring effluent quality, driving operations from "extensive" to "refined."

How It Works

Smart Aeration Control

Feedforward Compensation – Cascade Feedback – Blower Coordinated Control Strategy

On-demand Air Supply — Dynamically calculates theoretical air demand based on influent COD and ammonia nitrogen load, precisely controlling DO concentration in the aerobic tank by adjusting blowers and air control valves.

Energy Savings — Avoids power waste from over-aeration, effectively reducing aeration energy consumption (blowers in biological tanks account for 50%–70% of total plant energy consumption).

Smart Carbon Source Dosing Control

Shares influent load data with the aeration system to enable coordinated "carbon source dosing – dissolved oxygen control" — preventing excessive carbon source dosing from affecting aerobic oxygen demand.

Based on biological denitrification kinetics models, precisely responds to total nitrogen removal demand, reducing ineffective carbon source consumption.

Applications

Biological systems requiring stable operation under large influent fluctuations and imbalanced C/N ratios.

Wastewater plants facing dual pressure on energy and chemical costs, committed to cost reduction and efficiency improvement.

Wastewater treatment facilities seeking higher automation and reduced manual intervention.

Comprehensive Energy Reduction

Precise aeration significantly reduces blower energy consumption. Combined with carbon source savings, overall operating costs are significantly reduced.

Enhanced Process Stability

Precise control of DO and carbon sources creates optimal conditions for microbial growth, improving system shock resistance.

Carbon Emission Contribution

Reduced power and carbon source consumption directly supports wastewater plants in achieving carbon reduction goals.
