■ 제2협동 : 배액의 친환경 전기살균소독시스템 개발
□ Purpose& Contents
It is the purpose of this research to develop eco-friend disinfection system using electricity for recycling hydroponic system. To fulfil the purpose the experiments were conducted to establish the conditions of the components consisting of the disinfection system, to set the appropriate necessities such as electrodes, electric current, electric intensity, frequency, and so on. The reactor was designed and tested in pilot scale. Thereafter, the components were connected to the recycling system to test, of which its economic feasibility was evaluated. The managing program was developed as well.

□ Results
The developed disinfection system using electricity has several desirable points. It is very economical in price, less of maintenance efforts, out of any changes in nutrient composition of treated solution, no need of any chemicals for the disinfection as well as cleaning of the reactor, even though it has excellent disinfection abilities towards fungi and bacteria.

□ Expected Contribution
To have original technology for electric disinfection system
To substitute import and enhance export the disinfection system for hydroponics with high competitiveness
To less contamination of soil and water
To save water resources as well as fertilizers
