"The inside of the pipe was so clean, I sent a photo"

Last autumn, tomato grower Frank Dekker decided to start the upcoming season a little later. The ongoing cultivation was extended into December. As a result, January became the month for crop rotation at Dekker Glascultures.

The modified cultivation strategy allows just a little more time to thoroughly clean the greenhouse. A recent mishap, in which a piece of water pipe broke, still put a smile on the grower's face. "The inside of the pipe was so clean that I sent a photo to Robert," he says. 7 Color Led Facial Mask

Complete system The Robert mentioned above is Robert de Hoo from Ultramins. Since March 2021, Dekker Glascultures has been working with Ultramins' USAF ultrasound transmitters in the water basin and day stock. In both places, the ultrasound application ensures the water stays clean. The transmitter is hung in the silo or basin and produces ultrasound that causes cavitation. This creates pressure waves that kill algae and other microorganisms. In addition, Frank doses hydrogen peroxide. "This prevents dirt from adhering to the PVC walls," he says.

Dekker Glascultures was there early on and was the first grower to take delivery of Ultramins' complete system. "Our heater we use to disinfect our drain water broke down. That's when we started looking for something else." That became the Ultramins system, combined with hydrogen peroxide. "That is also important to me. Because of the combination, I changed my mind."

Photo autumn 2021: Dekker Glascultures also has a USAF transmitter in the drain, but the grower does not yet use drain water, Robert knows. Therefore, the grower uses the transmitter in his (private) pond with koi carp.

Clean basin The combination of hydrogen peroxide with ultrasound means the grower no longer suffers from the biofilm. "We replace the drip hoses during crop changes, but not other pipes. Now that a piece broke off a pipe that has been there for 20 years, you could see very well that it works."

Not that the grower doesn't have tests carried out. At an earlier stage, lab tests of water proved the operation, and a special camera was also used to image the operation of ultrasound. After all, humans cannot see the sound waves emitted by the emitters with the naked eye. However, once Frank's basin remained clean, and visibly cleaner than other basins without Ultramins technology, he was completely convinced.

Crazy roots are a thing of the past In the past, the grower's problems included algae. Almost daily, especially in summer, the fine filters at the pumps had to be cleared. "Now we take them off once every six weeks to see if everything is still clean. This is actually always the case. The parameters we monitor anyway also indicate that, but you still want to take a look yourself once in a while." The same goes for the drip hoses. "Every now and then during the season, we unscrew the drip hose to check for contamination with a finger in the hose and tube."

Abundant algae growth in the water at the tomato grower is a thing of the past. "That could cause blockages and, as a result, agrobacteria can grow significantly." The grower used to suffer from crazy roots at times. "We tried all kinds of things, as did a lot of growers. However, with the combination of ultrasonic and hydrogen peroxide, we work with now, everything stays clean."

"You can't get any cleaner than this" The crop rotation is the time when growers clean the entire greenhouse. With slightly less pressure on the kettle because of a modified cultivation schedule, Dekker Glascultures is doing it with its own people this year. Even with everything remaining so clean, the water system also gets a good shake-up. "The combination we're running with now takes the pressure off. There is significantly less pollution. That's good for our filters and systems. You can't get any cleaner than this."
