Nutrient solution cultivation methods are divided into non-circulating nutrient solution cultivation and circulation type nutrient solution cultivation depending on whether the drainage solution discharged during crop cultivation is discarded or collected and reused.
Although there are some differences depending on the cultivated crops and cultivation period, in general, the ratio of drainage after crop cultivation is about 15-40%, and since the drainage contains nitrogen or phosphate, if the drainage is continuously discarded, it will contaminate rivers and soil. there is a possibility to do it.
Also, the amount of water and fertilizer that is thrown away can be wasted.
Therefore, once the drainage is put into the crop, it is contaminated and there is a risk of pathogens spreading or spreading, so it is essential to sterilize the drainage through the drainage reprocessing system.
If you use Shinhan A-Tech's UV sterilization system, you can also save about 40% of fertilizer cost, so there are environmental and economic benefits.
