Water Treatment System With Parallel Membrane and Ion Exchange Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frequent cleaning and regeneration of degassers and water treatment devices in water treatment systems lead to significant system shutdown times and increased complexity due to the need for periodic disconnection and use of chemical solutions, as described in existing technologies.
Innovation Solution
A water treatment system with a membrane separator and ion exchange device, equipped with distribution pipes and controlled valves, allows simultaneous supply of chemical solutions to both components, reducing system shutdown time by parallel operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning and regeneration are performed for each device separately, then each device can be cleaned thoroughly, but system shutdown time increases significantly
Solution Approach 1:
The patent combines the cleaning processes of the degasser and water treatment device into a single integrated operation. By connecting both devices to a common chemical solution supply system with coordinated valve control, the chemical solution flows through both devices simultaneously, enabling parallel cleaning that reduces total shutdown time while maintaining effective cleaning of both components
2Reliability
If chemical solution is supplied to multiple devices separately, then each device receives adequate chemical solution, but system complexity increases
Solution Approach 1:
The patent employs a universal chemical solution supply system that serves multiple devices (degasser and water treatment device) through a single distribution pipe with coordinated valve control. This multi-functional approach allows the same chemical solution infrastructure to clean both devices effectively, reducing the need for separate cleaning systems and lowering overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces shutdown time associated with device regeneration by enabling parallel chemical treatment of degassers and ion exchange devices, minimizing the use of chemical solutions and effluent.
Implementation Method 1
a degasser equipped with a degassing membrane is used to remove dissolved gases (CO2 and O2) from the water being treated
Implementation Method 2
ion exchange resins, reverse osmosis membranes, and ultrafiltration membranes are used to remove ions and total organic carbon (TOC) contained in the water being treated
Implementation Method 3
Chemical solutions such as acids and alkalis are used to clean degassing membranes
