- Pre-filter the water to remove larger debris and sediment
- Run the water through a system that uses UV light and/or ozone to kill bacteria and viruses
- Test the water for pH, nutrient levels, and other factors to ensure it is suitable for hydroponic growth
- Add necessary nutrients and adjust pH as needed for optimal plant growth
Using river water for hydroponics is possible, but requires proper cleaning and disinfection prior to irrigation. While it may seem like a convenient and natural water source, river water can contain a variety of contaminants including bacteria, viruses, chemicals, and heavy metals. These contaminants can easily transfer to the plants and fruits grown with hydroponics, posing a serious health risk to consumers.
To properly clean and disinfect river water for use in hydroponics, consider the following steps:
