Product Design




To better demonstrate our filter, we made a virtual model using the Inventor Autodesk program as software.







The filter is composed of an internal cylinder where the alginate beads will be stored, and near its base there is a sequence of small hooded holes with a tiny grid (smaller than the diameter of the alginate beads) through which water will pass to a second compartment.




By Simon Stiven theorem about communicating vessels, which states water will reach the same level in all parts of the system because gravity and pressure are constant in each vessel (hydrostatic pressure), water will rise in parallel and cross into a third compartment and exit the system.







Water gets to the filter through a drain pipe (as the filter has versatility in its application, some systems described may vary depending on it) which runs through the middle of the filter to a bearing.







Then, as water rises, a 4-arm propeller moves along a central axis.







In the propeller’s arms, there are holes through which water will come out and get in touch with the alginate beads inside the filter, constituting the purpose of the filter.







In order to keep the inside of the filter out of the reach of exterior environment and dirt particles, we have developed a kind of roof with a split opening system, so that the user can perform any maintenance. For this, we designed a handle to open the system.







Finally, we apply in the software the materials we project, being the filter walls of concrete and the mechanisms such as the propeller, pipe and the roof made of metal.
