Clearly the success of a hydroponics crop depends on the quality of the water being used to grow the plants. Water parameters that have a direct impact on crop success include:
Oxygen level: low levels limit plant growth.
Hydrogen sulphide (H2S) concentration: High levels reduce fertilizer effectiveness and promote growth of anaerobic bacteria.
Microbial loading: High levels of bacteria in the water compete with the plants for nutrients. Root born pathogens are detrimental to plant health.
Algae growth.
The benefits of ozone to hydroponics are:
: The elimination of H2S.
: The increase in oxygen levels.
: The elimination of microbes, algae and root borne pathogens including powdery mildew, Fusarium and Pythium.
: Savings on chemical fertilizers.
Higher crop yields.
: All water is recycled; sewer/dumping charges are virtually eliminated. Only in the case of elevated salt content due to extensive evaporation, a blow down may be required, usually only after many months of operation.
: Up to 50% of otherwise lost nutrition is recovered and returned back to the feed operation system.
: All fungi, viruses, bacteria and parasites are eliminated.
: The makeup water demand is greatly reduced.
