Basin water is loosely mixed with drain water untreated , i.e. without disinfection ; all pathogen in the basin are sent directly into the greenhouse . Robert de Hoo and Kees Luykx , distributer and producer of USAF ultrasonic transmitter , are stunned by this .
Robert : " We can in reality say that there is often no sixth sense into the quality of the basin water used . The drainpipe weewee is almost always disinfected , but that is hardly ever done for basin urine . "
He points to practical case . " Recently , the Tomato brown rugose fruit virus ( ToBRFV ) was find in the basin weewee of a tomato grower in Belgium , while the computer virus had not ( yet ) been rule in the glasshouse , and at a agriculturalist in West - Friesland , a very strong concentration of the Pythium fungus was incur in a fully covered basin ( against algae maturation ) . In both case , the water was pumped forthwith into the mixing container without any form of disinfection . Both agriculturalist found out about these infection by accident . If they had used this contaminated water system in the greenhouse , this could obviously have resulted in a lot of extra employment and big damage costs . "
USAF ultrasonic transmitters
Both companies contacted Ultramins in reply to previous articles on GroentenNieuws . Ultramins is the undivided distributor of the USAF ultrasonic transmitters that combat micro - organisms in basin and silo weewee .
Robert : " We were asked whether our USAF supersonic vector could volunteer a solvent , and , of track , they can . However , we are surprised by the fact that growers are still prepared to use basin water at their own delicacy . Various strict and expensive measures are take to ferment as safely as possible . For instance , no visitors are admit in the greenhouse , shoe are disinfected , protective article of clothing is worn and cock are often disinfected . Laboratories can easily tell what is in the washbowl water from the water samples , so you are not run to take any risks with that , are you ?
" However , even if you know the effect , it can be unlike tomorrow as basin water system is an open system of rules . Basin water can be disinfected in a relatively childlike style and in combination with H2O2 USAF , which kills off more than 99.99 % of the micro - being . These vector work 24/7 at low operational costs , demand no maintenance , are environmentally well-disposed , and deliver the good results . "
TestingTests with ToBRFV - contaminate water , recently done by Proeftuin Ron Peters , showed that computer virus in the water causes contaminant of the plant . ( Read the article about the test here ( NL)).These are hazard growers should not take , according to Robert . " However , people often still suppose in a traditional way : ' This is how we have always done it , we have never disinfected the washstand water before ' . While in fact , every raiser knows that there are enough danger mill around in this water flow , especially when other growers or arable Farmer are active in the locality . "
Kees Luijkx , USAF producer : " We know for certain that , when all the urine is disinfect by USAF , payoff will improve and failures will decrease . Every cultivator knows that cleaner polish urine leads to in high spirits yield . It is therefore surprising that risks are still being taken with basin and cultivation water . The risk of exposure that are currently being taken can easily lead to enormous losses , which could easily have been prevented . say that this method acting of disinfection bestow with it an extra yield of only 1 to 2 % - then any investment is quickly recoup .
