Natural Zeolite Block for Water Purification Without Sand Aggregate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purification blocks made from zeolites require high energy, emit carbon dioxide, and use sand as an aggregate, which blocks natural pores and increases manufacturing costs, while also potentially harming the environment.
Innovation Solution
A natural zeolite block is created by mixing clinoptilolite, mordenite, and illite minerals of specific sizes, bonded with cement and water without sand, to form a porous structure that can be molded into blocks for effective water purification, preventing eutrophication and heavy metal contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sand is used as aggregate to bond zeolite particles during molding, then the mechanical strength of the block is improved, but the natural pores of the zeolite are blocked and water quality improvement capability is decreased
Solution Approach 1:
The patent removes sand from the mixture composition entirely, extracting the harmful aggregate that blocks pores. The bonding is achieved through alternative mechanisms (cementitious bonding between zeolite particles) that do not require sand, thereby preserving pore structure while maintaining block integrity.
Solution Approach 2:
The patent utilizes the natural porous structure of zeolite minerals as the primary functional component. By forming blocks from zeolite particles bonded without sand fillers, the natural pores remain open and accessible, allowing the material to perform its water purification function through adsorption and ion exchange mechanisms.
2Reliability
If clinoptilolite, mordenite, and bentonite are calcined at high temperature and pulverized to fine mesh, then the reactivity and adsorption capacity are improved, but energy cost increases and carbon dioxide emission occurs
Solution Approach 1:
The patent utilizes zeolite minerals that naturally possess the required porous structure and ion exchange capacity without requiring high-temperature calcination treatment. The minerals are used in their natural or minimally processed state, performing the necessary activation function beforehand through their inherent properties rather than through energy-intensive thermal processing.
Solution Approach 2:
The patent converts the natural crystalline structure of zeolite minerals, which would otherwise require energy-intensive processing to activate, into a direct benefit by utilizing their innate porosity and ion exchange capabilities. The natural mineral structure becomes the functional advantage, eliminating the need for harmful high-temperature calcination.
3Stability of the object's composition
If zeolite particles are pulverized to 200-400 mesh and mixed with sand, then the mixing homogeneity is improved, but the manufacturing cost increases and environmental harm occurs
Solution Approach 1:
The patent extracts sand from the mixture, eliminating the need for fine pulverization to 200-400 mesh. Coarser zeolite particles can be used effectively without sand fillers, reducing energy consumption for grinding and eliminating environmental harm associated with fine particle production and sand mining.
Solution Approach 2:
The patent changes the particle size parameter from fine 200-400 mesh to coarser particles, and changes the composition parameter by removing sand entirely. This parameter modification maintains mixing homogeneity through alternative mechanisms while reducing manufacturing cost and environmental impact.

Implementation Method 2
The clinoptilolite may be exchanged to positive ions according to conditions to thus perform positive ion exchange with metal ions having high antibacterial effectiveness, such as Ag, Cu, and Zn
