Ion filtration system could cut hydroponic operating costs
By Brandi Cowen
A new ion water filtration system could eliminate one greenhouse tomato grower’s need to run a water pasteurization system in his hydroponic operation.
In a news item appearing on the Agricultural Adaptation Council’s (AAC) website, Guido van het Hof of Ontario’s Great Northern Hydroponics reported that the system’s filtration is “so good” that it filters plant pathogens, bacteria, viruses and fungi, as well as sodium, sulphates and chlorides from the water.
According to the AAC:
“Van het Hof’s goal is to make the system a complete closed loop, meaning all water and nutrients would be recycled. He currently spends $75 to $100 per day to run his water pasteurization system, which he would no longer need to keep pathogens at bay.”
