Aquatic Facility Water Chemistry Controller with Variable Rate Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aquatic facilities face challenges in maintaining optimal water quality due to separate management systems for water chemistry and circulation, requiring operators to learn distinct interfaces for water pumps and chemistry controllers, and often result in inefficient energy usage and suboptimal water turnover rates.
Innovation Solution
An integrated system that combines a water chemistry controller with a variable rate water pump and motor driver, allowing the water chemistry controller to manage pump operations through control signals and monitor status signals, providing a unified user interface for managing both water chemistry and pump operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate management systems are used for water chemistry and circulation, then each system can be independently controlled, but operators must learn distinct interfaces and system complexity increases
Solution Approach 1:
The patent combines the water chemistry controller and circulation pump controller into a single integrated control system. The water chemistry controller now also manages the variable rate water pump, eliminating the need for separate pump control interfaces. This merging of control functions directly reduces the number of distinct interfaces operators must learn while maintaining independent control capabilities for both chemistry and circulation functions.
2Use of energy by moving object
If separate management systems are used for water chemistry and circulation, then each system operates independently, but energy usage efficiency decreases
Solution Approach 1:
The integrated control system uses feedback from water chemistry sensors and pump operational data to dynamically adjust pump run times and water circulation rates. The system monitors turnover rate compliance and chemical dosing requirements, then optimizes pump operation accordingly. This feedback mechanism enables energy-efficient circulation scheduling that responds to actual water quality conditions rather than operating on fixed independent schedules.
Solution Approach 2:
The system dynamically adjusts the water pump's operating rate based on real-time water chemistry conditions and turnover rate requirements. Rather than fixed-speed operation, the variable rate pump adapts its circulation rate to match actual facility needs, improving energy efficiency by reducing circulation when water quality is optimal and increasing it when turnover requirements demand faster water movement.
3Reliability
If separate management systems are used for water chemistry and circulation, then installation is straightforward, but water quality optimization is limited
Solution Approach 1:
The water chemistry controller is designed to perform multiple functions: it continues to manage chemical dosing and monitoring while also controlling the variable rate water pump. This multi-functional controller monitors both water quality parameters and circulation performance, enabling comprehensive water quality optimization from a single control platform rather than requiring coordination between separate independent systems.

AI summary
A system for controlling water within an aquatic facility includes a water chemistry controller, a variable rate water pump adapted to move water in the facility, and a variable rate motor driver operationally coupled to the water pump for variably energizing the water pump. The variable rate motor driver is coupled to the water chemistry controller to allow the water chemistry controller to manage the operation of the water pump.
