Solution Overview
Problem
Current dechlorination compositions for water treatment require costly and cumbersome processing steps, such as heating, to form solid objects like tablets, which increases manufacturing costs and reduces throughput.
Innovation Solution
A dechlorination composition comprising alkali metal sulfite, borate, hydrogenated vegetable oil, and saccharide, which can be combined and compressed into solid forms like tablets or pellets without extensive processing, using a method that includes milling the sulfite to a specific particle size and exposing the mixture to ambient conditions or heat to achieve desired hardness and dissolution rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If current dechlorination compositions are processed using conventional methods (heating, drying, granulating), then the solid tablets can be formed, but the manufacturing cost increases and throughput decreases
Solution Approach 1:
The invention extracts and eliminates the unnecessary heating and extensive drying steps from the conventional manufacturing process. By formulating the dechlorination composition with materials that naturally bind and compress well at ambient conditions, the process removes (takes out) the energy-intensive thermal processing steps, thereby simplifying manufacturing and increasing throughput without compromising tablet integrity.
Solution Approach 2:
The invention applies preliminary action by pre-formulating the composition with optimal ratios of binders and fillers that enable direct compression. The materials are selected and pre-mixed to achieve proper flow and compression characteristics, allowing the tablet formation to occur in a single compression step without subsequent drying or regranulation, thus eliminating bottlenecks in the manufacturing process.
2Strength
If heating is applied to form dechlorination tablets, then the tablets achieve desired hardness, but processing time and energy consumption increase
Solution Approach 1:
The invention replaces the thermal system (heating and drying) with a mechanical system (direct compression). By using materials with appropriate compressibility and binding properties, the desired tablet hardness is achieved through mechanical compression force alone, eliminating the need for thermal processing and significantly reducing processing time and energy consumption.
Solution Approach 2:
The invention changes the material parameters by selecting binders and fillers with specific physical properties that enable cold compression. The composition is formulated with materials that have optimal particle size, moisture content, and binding characteristics to achieve sufficient hardness under compression without requiring thermal activation, thus changing the processing parameters from thermal to mechanical.
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 solution allows for the production of dechlorination solids with enhanced hardness and controlled dissolution rates, enabling efficient removal of residual chlorine from water while reducing processing costs and complexity.
Implementation Method 1
Chlorine, in a formal +1 oxidation state (e.g. hypochlorous acid or hypochlorite anion) and simply called chlorine herein, is the most commonly used disinfectant... a dechlorination step is implemented to neutralize the residual chlorine
Implementation Method 2
dechlorination compositions are commonly formed into tablets or pellets so that the dechlorination compositions slowly dissolve and interact with the residual chlorine dispersed throughout the treated water
