One of the biggest challenges that you have when you use a hydroponic system is the water usage. Most people struggle with this, given the insane water bills. However, you don’t have to worry about that. In case you want to maintain a highly efficient grow room, you need to learn one or two tricks that will help you save water by cleaning and reusing the water from the hydroponic system.
It’s amazing the things you can do with a hydroponic system. In fact, most people barely know this, but you can recycle the water you use. However, there are some challenges that you must be aware of when it comes to recycling hydroponic water. You must be very careful about this because recycled water might be carrying diseases, viruses, and even bacteria. It’s, therefore, important that you take this into consideration before you use recycled water for your plants. The best way is to ensure the recycled water is clean and sterilized so that you don’t pass on the infection to the plants.
There are three ways you can go about this:
- UV Disinfection
- Ozone sterilization
This is one of the best options you have, especially since there’s no chemical use involved. In case you’re the kind of grower who wants to keep the entire process natural, UV disinfection is the best option you have.
How does it work? Water is passed through a radiation chamber. In this chamber stay high-pressure UV lamps, whose rays penetrate the water molecules, killing any toxic bacteria and pathogens that might be present.
This is a safe process, especially since it’s the same thing that’s used by water bottling companies to make drinking water safe for consumption. If you’re thinking about costs, this is one of your best alternatives, compared to ozone sterilization and pasteurization. Besides, this is a natural process, meaning that there are no dangerous byproducts released. Perhaps one of the challenges you need to know about this process is that inorganic compounds that are in water or chemical contaminants are not neutralized.
This process is also referred to as ozonation. In ozonation, water is infused with ozone, the natural gas present in the ozone layer which is created by the UV rays from the sun. It’s also possible to create it through artificial processes, and help in recycling and treating hydroponic water.
You will need ozone generators for this process, which don’t come cheap either. That being said, however, this is one of the most effective ways of sterilizing water in your hydroponic system.
In this process, you use heat to kill any pathogens that might be present in your water. This is the same process that’s used in milk factories. What happens here is that the heat exchanger heats or cools down the water in the hydroponic system. There’s no need for pre-filtration. This is also a good method, especially when you want to reduce the risk of having minerals or other residue in the water.
