Rotating Holder Calcium Hypochlorite Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment systems using calcium hypochlorite face challenges with inconsistent dosing due to high solubility and residue deposition, leading to clogging and uneven treatment, as well as bridging/fusing of tablets when not in use.
Innovation Solution
A method involving a water treatment apparatus with a holder that directs a stream of water horizontally against a lateral side of a water treatment substance body, such as a bed of calcium hypochlorite pellets, to abrade and dissolve the substance, ensuring consistent dosing and preventing residue accumulation by imparting a rotational flow to the water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calcium hypochlorite is used as a disinfectant, then effective water treatment is achieved, but inconsistent dosing occurs due to high solubility and residue deposition
Solution Approach 1:
The patent implements a rotating holder mechanism that continuously rotates the calcium hypochlorite substance body, transforming the static dissolution process into a dynamic one. This rotation ensures uniform exposure of all surfaces to water flow, preventing localized residue buildup and maintaining consistent dosing throughout the treatment process.
Solution Approach 2:
The invention introduces rotational movement as a new dimension to the traditional linear water flow approach. By adding rotational motion to the holder, the system creates multi-directional water-substance contact, eliminating the single-point contact limitation and achieving uniform dissolution across the entire substance body surface.
2Measurement precision
If calcium hypochlorite tablets are submerged in water, then direct contact dosing is achieved, but bridging and fusing of tablets occurs when not in use
Solution Approach 1:
The system employs periodic rotation of the holder mechanism, alternating between rotation during active dosing and stationary position during idle periods. This periodic action allows the tablets to remain intact during non-use while achieving consistent dosing through controlled rotation during operation, preventing both bridging and excessive dissolution.
Solution Approach 2:
The rotating holder design allows the calcium hypochlorite tablets to self-dose the water through controlled rotation and water flow interaction. The system automatically regulates the dissolution process through mechanical rotation without requiring external intervention, maintaining tablet integrity while ensuring accurate dosing delivery.
3Productivity
If water flows linearly over calcium hypochlorite bed, then treatment occurs, but clogging of mesh openings with insoluble residue is common
Solution Approach 1:
The patent replaces static mesh structures with a dynamic rotating holder system. The rotation continuously moves the calcium hypochlorite substance body away from any fixed mesh openings, preventing residue accumulation and clogging while maintaining treatment throughput through sustained water-substance contact.
Solution Approach 2:
The invention extracts the calcium hypochlorite substance body from direct contact with fixed mesh structures by implementing rotation. This separation eliminates the clogging problem associated with static mesh openings while preserving the dosing function through controlled rotational exposure to water flow.
4Reliability
If calcium hypochlorite is highly soluble, then effective disinfection is achieved, but controlling the water interface becomes difficult
Solution Approach 1:
The rotating holder mechanism transforms the difficult-to-control interface contact into a dynamically controlled process. Rotation provides predictable and uniform water-substance interaction, making the high solubility of calcium hypochlorite manageable through consistent mechanical motion rather than relying on passive diffusion or uncontrolled contact.

AI summary
A method of treating water includes directing a stream of water towards a lateral side of a water treatment substance body contained within a holder. The water stream serves to abrade the water treatment substance body, thereby to dose the water with the water treatment substance. Dosed water is thus formed. The dosed water is allowed to pass through at least one opening in the holder.
