I was studying a Royal Institution lecture by Felix Flicker about Magnetic Monopoles #physics & thought of a way to use an ultrasonic transducer in a tuned plastic low-cost water vessel to perform high performance low energy consumption water purification without consumable filters or replaceable media, that can run on a small PV panel or a few LR6 or AA alkaline batteries, to improve access to sanitation & clean drinking water worldwide, for all people, to reduce water born disease burden, pain & suffering & to make life better for everyone, especially given the scope of micro-plastics & other water pollutant levels increasing & relative rarity & uneven distribution of fresh water resources worldwide.
Harmonic Water Filtering Principal Explanation
Imagine a sealed container, like a small glass aquarium tank. When dirty water added to this container, a resonant standing wave or moving wave can be utilized to push ions & particles & other contaminate species in the water like bacteria or viral particles from one side of the tank & force the bad stuff to accumulate on the bad side. A tap on the lower part of the dirty side can be opened to drain out the funky stuff.
Successive passes of ultrasonic waves tuned to the resonant frequency of the water & tank can be used to further purify the water of contaminants. A freshwater tap, opposite side of the tank as the dirty drain tap, can be opened to release pre-treated water for addition of a copper or silver based or UV based sterilization unit to decontaminate the water by killing pathogenic bacteria.
The main idea, to make a low cost, low energy, high performance, injection molded plastic, tunable acoustic water filtering system for improving sanitation in developing countries & compact higher cost units for hikers, backpackers or explorers who can afford a more expensive unit with similar functional mechanism, the profit from the sale of which can be used to subsidize the cost of lower cost units given at a discount to the poor or low income people who lack access to fresh clean water, since water diseases are one of the leading causes of human suffering & pain & discomfort worldwide.
Given the scope of micro-plastics & other pollutant levels increasing in the environments of Earth, specially where people are living & can make use of water for drinking to stay hydrated, cooking & to clean up with improve hygiene.
