Modular RO System Double Remineralization pH Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reverse osmosis systems with normal remineralization can only raise the pH of purified water to 7.0, and they often use canister filter housings that require frequent replacement, which can lead to potential water damage if not maintained, whereas modular-filter based systems lack effective double remineralization methods to achieve a pH of 8.0 without using multiple filters.
Innovation Solution
The Tap Master Artesian Full Contact system employs a modular-filter based reverse osmosis system that forces purified water through the same remineralization cartridge twice using a tubing loop, tee fittings, and check valves to raise the pH from 6.2-6.8 to 7.5-8.5, eliminating the need for multiple filters and preventing filter housing aging issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If canister filter housings are used in reverse osmosis systems, then the system structure is stable and reusable, but the filter housing weakens and bursts with age causing water damage
Solution Approach 1:
The system divides the filter assembly into modular components where the filter element and housing are separate. The canister housing is reused while only the filter cartridges need replacement, isolating the aging housing from the consumable filter media that causes bursting issues.
Solution Approach 2:
The filter cartridges are designed as disposable components that are replaced regularly (every 6-12 months), while the durable canister housing is retained. This replaces the entire assembly approach with a reusable housing plus disposable cartridge model, eliminating the bursting risk from aging housings.
2Manufacturing precision
If multiple remineralization filters are used to raise pH to 8.0, then the pH target is achieved, but the system complexity and cost increase
Solution Approach 1:
The system recirculates water through the single remineralization filter multiple times in a continuous loop, ensuring prolonged contact time with the remineralization media. This repeated passage through the same filter achieves the target pH of 8.0 without requiring multiple separate filters, maintaining simplicity while achieving precision.
Solution Approach 2:
The recirculation pump creates periodic flow cycles through the remineralization filter, repeatedly passing water through the filter media until the desired pH is achieved. This periodic recirculation action replaces the need for multiple sequential filters with a single filter used repeatedly.
3Device complexity
If a single remineralization filter is used, then the system is simple and cost-effective, but the pH can only be raised to 7.0
Solution Approach 1:
The recirculation system continuously pumps water through the single remineralization filter in a closed loop, maximizing the contact time and number of passes through the filter media. This continuous recirculation allows a single filter to achieve pH 8.0 by repeatedly exposing the water to the remineralization process.
Solution Approach 2:
The system uses a dynamic recirculation pump to control the flow rate and circulation speed through the filter, adjusting the contact time as needed. This dynamic control allows a single static filter to achieve the pH precision that would otherwise require multiple filters in a static configuration.

Function Achieved in This Case
This approach consistently produces alkaline water with a pH of 8.0 on average, ensuring reliable water quality and safety by preventing filter housing bursting and eliminating the need for multiple remineralization filters, while maintaining the benefits of a modular-filter based system.
Implementation Method 1
a forced remineralization system whereby the purified water is channeled through the same remineralization cartridge twice
Implementation Method 2
forces the purified water through one remineralization filter a second time to reliably raise the pH to 7.5 to 8.5

AI summary
The water treatment system is a modular-filter based residential reverse osmosis (RO) system that remineralizes the purified water twice to ensure the water is alkaline, but uses only one remineralization filter. The system forces the water to undergo remineralization twice in a modular-filter based residential RO system, using only one remineralization filter. The water produced from the water treatment system is alkaline with a pH of at least 7.5 up to a maximum pH of 8.5. A pH of 8.0 is the mean average.
