Smart Dosing Control Solutions for Wastewater Treatment Plants

Chemical phosphorus removal and carbon source supplementation are the two key dosing cost drivers in wastewater plants. Traditional experience-based dosing often leads to excessive chemical consumption and unstable effluent quality.

We provide a smart control solution based on AI and process models. By analyzing inlet load data in real time, the system precisely calculates and doses phosphorus removal chemicals and carbon sources — optimizing both chemical consumption and effluent quality while ensuring stable TP and TN compliance.

How It Works

Smart Chemical Phosphorus Removal Dosing Control

Feedforward Adjustment — Builds a phosphorus removal dosing model based on inlet flow rate and pre-dosing orthophosphate concentration.

Feedback Correction — Uses effluent total phosphorus (TP) concentration as feedback, with neural network algorithms for rolling model optimization.

Dual-mode Operation — Supports coordinated control between AI smart mode and model-based automatic mode, ensuring system reliability.

Applications

Coordinated biological and chemical phosphorus removal control in municipal wastewater treatment plants.

Wastewater plants with insufficient influent C/N ratio requiring substantial carbon source supplementation.

Wastewater plants facing both phosphorus removal and denitrification pressure, requiring precise chemical cost control.

Chemical Cost Savings

Chemical Cost Savings: Practical case studies show 10%–30% savings in chemical consumption.

Stable Effluent Compliance

Dynamically responds to flow and water quality fluctuations, ensuring stable TP and TN compliance.

Improved Operational Efficiency

Upgrades dosing from experience-dependent to data-driven, enabling refined management.
