Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling chemical dosing in water treatment plants, such as seawater desalination, rely on sampling experiments and operator knowledge, making it difficult to adjust chemical dosages in real-time to account for changes in feed water conditions, leading to inefficiencies and potential damage to downstream processes.

An apparatus and method for chemical dosing optimization that analyzes real-time data to determine optimal chemical dosages, using a chemical dosing management part, optimization part, and output control part to adjust dosages based on current conditions while maintaining treated water quality within normal ranges, with features like control mode management and correction mechanisms to prevent damage to late-stage processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time data analysis and automated control systems are implemented for chemical dosing optimization, then chemical usage efficiency and treated water quality are improved, but device complexity and implementation cost increase
Solution Approach 1:
The system implements real-time feedback control by continuously monitoring feed water conditions (turbidity, flow rate, temperature) and adjusting chemical dosing accordingly. The control unit receives sensor data, compares it with target values, and automatically modifies dosing pump operations to maintain optimal treatment efficiency while adapting to changing water conditions.
Solution Approach 2:
The automated control system enables the water treatment process to self-regulate chemical dosing without manual intervention. The system autonomously analyzes real-time water quality parameters and adjusts dosing rates, reducing dependency on operator knowledge and sampling experiments while improving dosing precision and response time to water condition changes.
2Reliability
If chemical dosing is increased to ensure treated water quality, then water treatment reliability is improved, but chemical consumption and operational cost increase
Solution Approach 1:
The system dynamically adjusts chemical dosing rates based on real-time feed water conditions rather than using fixed dosing schedules. The control unit continuously modifies dosing parameters according to measured turbidity, flow rate, and temperature variations, ensuring reliable water quality treatment while minimizing chemical consumption by dosing only when and where needed.
Solution Approach 2:
The control system changes dosing parameters (flow rate, concentration, timing) based on real-time water quality parameters. By monitoring and responding to changes in feed water characteristics, the system optimizes chemical dosing levels to maintain treated water quality within acceptable ranges while reducing overall chemical usage compared to conventional fixed-dosing methods.
3Ease of manufacture
If manual sampling experiments and operator knowledge are used for chemical dosing, then implementation simplicity is maintained, but adaptability to real-time water condition changes deteriorates
Solution Approach 1:
The system replaces manual sampling and operator-based dosing decisions with automated electronic sensing and control. Sensors continuously measure water quality parameters, and a control unit processes this data to automatically adjust dosing pumps, eliminating the need for manual sampling experiments and operator intervention while enabling real-time adaptation to water condition changes.
Solution Approach 2:
The control unit acts as an intermediary between water quality sensors and chemical dosing pumps. It receives real-time data from sensors, processes the information according to control algorithms, and generates appropriate control signals for dosing equipment, enabling automated real-time adjustment of chemical dosing without direct human involvement.
