1. System Overview

The Modao Intelligent Dosing System for Wastewater Treatment is an intelligent solution developed for the chemical dosing stage in wastewater treatment. The system automatically monitors water quality indicators, combines advanced intelligent algorithms with automated control technology, precisely controlling the dosing amount in the wastewater treatment process, achieving automated and intelligent management throughout the entire wastewater treatment process, helping enterprises improve treatment efficiency, reduce operating costs, and ensure stable and compliant effluent quality.

2. System Functions

(1) Automatic monitoring of water quality indicators

Multi-parameter real-time monitoring: The system is equipped with high-precision water quality sensors that can monitor key water quality indicators in wastewater such as turbidity, pH, ammonia nitrogen, COD (Chemical Oxygen Demand), and SS (suspended solids concentration), providing precise data support for dosing control.

Data transmission and storage: monitoring data is transmitted in real time to the control center via wired or wireless methods and stored in a cloud database, supporting historical data queries and trend analysis, providing data support for process optimization.

(2) Intelligent Dosing Control

Feedforward + feedback composite control: The system adopts a closed-loop control mode of "feedforward + feedback," where the feedforward stage quickly models and predicts dosing requirements based on influent quality parameters (such as flow, turbidity, pH, etc.); During the feedback phase, the dosing amount is fine-tuned based on real-time data on effluent quality to ensure stable and compliant effluent quality.

Model Predictive Control (MPC): Embedded in process models, combined with historical data and real-time feedback, dynamically optimizes dosing strategies to improve dosing accuracy and response speed.

Multiple dosing modes support: Supports various dosing modes by concentration, flow rate, ratio, and other methods to meet different wastewater treatment process requirements.

(3) Emergency Response and Safety Assurance

Abnormal Early Warning and Emergency Response: The system monitors water quality and equipment status in real time. When abnormal situations such as water quality exceeds standards or equipment malfunctions, it immediately issues audible and visual alarm signals and notifies operators via SMS, email, or platform to promptly address the issue.

Emergency Plan Management: Built-in emergency plan database that automatically generates handling suggestions based on different abnormal situations, guiding operators to respond quickly and reducing accident risks.

Safety protection mechanisms: The system features overload protection, leakage protection, explosion-proof design, and other safety features to ensure the safety of equipment and personnel.

(4) Remote monitoring and operation and maintenance management

Remote monitoring platform: The supporting software system supports remote access via Web/APP, allowing operators to view water quality data, equipment status, dosing curves, and other information anytime and anywhere, enabling remote monitoring and real-time regulation.

Intelligent Operation and Maintenance Management: The system automatically generates reports such as equipment operation logs, fault records, and maintenance reminders, supporting remote log downloads, program upgrades, parameter debugging, and other functions to reduce operation and maintenance costs.

Multi-plant centralized control: Supports centralized monitoring and management of multiple plants and devices, enabling optimized resource allocation and efficient collaboration.

3. System Advantages

(1) High dosing accuracy and stable water quality meeting standards

The system uses high-precision sensors and intelligent algorithms, keeping dosing accuracy within ±3%, far superior to manual operation (with errors often exceeding ±20%), ensuring stable and compliant effluent quality.

Real-time monitoring and dynamic adjustment functions effectively respond to fluctuations in influent water quality, preventing excessive water quality or secondary pollution caused by insufficient or excessive dosing of chemicals.

(2) Saving chemical costs and reducing operating expenses

Precise dosing reduces chemical waste, averaging 15%-30% savings in chemical usage, with significant cost savings over long-term operation.

Intelligent algorithms optimize dosing strategies, reducing equipment wear and energy consumption, further lowering operating costs.

(3) Improve operational efficiency and reduce manual intervention

The system operates fully automatically, requiring no manual inspection, recording, or adjustment, operating continuously 24 hours a day, significantly improving work efficiency.

Remote monitoring and intelligent operation and maintenance functions reduce on-site operator staffing, enabling "unattended" or "low-attendant" modes.

(4) Enhance safety guarantees and reduce management risks

Real-time monitoring and abnormal warning functions enable timely detection and handling of abnormal situations such as excessive water quality and equipment failures, avoiding environmental accidents and administrative penalties.

Systematic data recording and analysis provide scientific evidence for process optimization and decision support, enhancing enterprise management levels.

(5) Modular design, easy to expand and upgrade

The system adopts a modular design, with each functional module operating independently and flexibly combinable, making it easy to customize configurations according to the actual needs of enterprises.

Supports software upgrades and function expansions. As wastewater treatment technology advances and water quality requirements increase, the system can be continuously optimized and upgraded to maintain its advanced and applicability.

4. Application Scenarios

The Modao Sewage Treatment Smart Dosing System is widely used in municipal sewage treatment plants, industrial wastewater treatment plants, water plants, and river black and odorous water treatment areas. It is especially suitable for scenarios with large fluctuations in influent water quality, complex treatment processes, and high requirements for effluent water quality.
