Water is one of the most important raw materials in the horticulture industry. However, water is a precious commodity that will be even scarcer in the future. One of the challenges of modern greenhouses is the efficient use of water. Re-use of drain water is a benefit for the environment, but also has financial benefits. By recycling drain water, you save water and fertilizers.
The importance of sterilizing drain water
By recirculation of drain water, the risk of spread of bacteria, fungi and viruses arise. A drain water sterilizer can limit this spread. A sterilizer kills the bacteria, fungi and viruses that are harmful to your plants. At the same time, the sterilizers preserve the oxygen and the fertilizer in the water.
The functioning of a sterilizer
There are many ways to disinfect drain water. The most commonly from of drain water disinfection is the disinfection by means of heat. A sterilizer kills germs by means of heat. The advantage of a sterilizer which makes use of heating is that it very efficiently kills all germs. In addition, the temperature and residence time are easily controllable.
Responsible drain water sterilizing
In order to reduce the energy consumption to a minimum, the heat which is released during the cooling of the sterilized water will be used again to heat the contaminated water. Enerdes sterilizers use heat to kill the micro-organisms. The drain water is heated quickly, then kept for some time at that temperature and cooled back in the counter-current. The heat that is released during this process is re-used to heat polluted water.
An Enerdes sterilizer disinfects 99.9% of your drain water, while ensuring that all the oxygen and fertilizers retain in the water. In addition, the sterilizer is very energy efficient and has a long lifespan.
