I managed to publish my DIY reverse osmosis filtration system with timer functionality and automatized flushing features on GitHub. It is an innovative approach to automating a reverse osmosis water filtration system. It utilizes a Raspberry Pi Pico, programmed with MicroPython to control four valves the are coordinated for a filtration process. Its main features are:

  • Automatic flushing of the osmosis membrane every few hours to prevent germ development in the filters.
  • Automatic disposal of the first filtered water (which contains more particles due to the lowered pressure in the osmosis membrane during idle time).
  • Setting a fixed time interval for water filtration to yield a specific amount of water, which can be stored via a long button press.

The project is developed in Python and is shared under the GPL-3.0 license. For an in-depth understanding and access to the script as well as a list of all hardware parts, you can visit my GitHub repository.
