The formation of biofilm is a naturally occurring effect of any liquid that encounters a surface.
Without any action, the risk of losing crops and a higher operational cost is unavoidable due to:
- blockage of drip irrigation systems due to the formation of slime
- the growth of damaging bacteria or water molds such as phytophthora , fusarium oxysporum, agrobacterium, coliforms…
- spreading of legionella in pipes and heat exchangers
- the growth of phytoplankton and algae in tanks and piping systems
- the formation and scaling effects of calcium salts (like limestone on UV-lamps)
The installation of ultrasound transducers at certain strategic locations can remove and prevent bio-fouling. The result is a reduction of the total colony forming units (cfu’s)
This again results in both positive economic and ecological effects by reducing:
chemicals/herbicides/fungicides/descalants/inhibitors or even antibiotics.
The European Union stimulates independence of chemical pesticides and herbicides, they may only be used as a last resort solution.
The amount of installed ultrasound systems grows steadily, especially in the hydroculture and in combination with “sensitive growing techniques” such as NFT and MGS.
