Many years ago AZCO pioneered a full-scale wastewater recovery system for greenhouses. Ozone not only cleans the water it also increased levels of oxygen which is desirable.

There are hardly two identical horticulture operations in the world. AZCO engineers are ready to review and utilize your existing equipment (such as aeration tanks, pumps, filters and buildings), to be fitted for the new purpose, or to assist in new system integration.

With the right system installed virtually all of the wastewater can be recovered.

The slightest amounts of iron, manganese, organics or other oxidable materials will plug the capillaries in the hydroponic water distribution. Chlorination is not an option because it forms very toxic chloro-organic compounds known as THMs. De-chlorination is not completely effective for removing the THMs, and subsequent discharge into the soil would ultimately lead to contamination of the ground water. In recirculation systems, the THMs would accumulate and poison the plants.

AZCO systems for makeup water are totally nontoxic and the only byproduct created is oxygen. We make our comprehensive calculation is simple enough to understand so as to demonstrate that AZCO applies only the most economical and reliable solution to the water problem.


1. All water is recycled, sewer 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.
2. Up to 50% of otherwise lost nutrition is recovered and returned back to the feed operation system.
3. The makeup water demand is greatly reduced.
