After years of growing , Van der Knaap Group is launching its sodium remover . ' Natrex ' selectively press out the sodium that is present in the drain H2O , allowing for the drain water to continue to be reuse without fall back the crop protection products and other utilitarian nutritional elements . The first system has now been installed at a agriculturalist in Canada for an area of more than 12 hectare . Residual weewee flowsSince 2018 , the refinement of residual flows has been mandatory in The Netherlands . At least 95 % of the crop protective products must be absent from the release of sewer water . This was only one of the first steps towards emission - free polish . From 2027 , the sphere must abide by with the ' zero expelling ' goal . The uprise sodium levels are the main understanding for discharge .
Reusing waste pipe waterDrainage water can usually be reused as irrigation water supply . reuse more drain water thus stave off the need to release . However , Na accrual , in particular , can be a reason why drain water can no longer be recycle . In the coming age , run out water that can no longer be reused may be discharge to a lesser extent .
Sodium ( Na ) is an element that is absorbed to a limited extent by most crop . As a result , the sodium concentration in the substratum and the drain water will rise to the peak where recirculation is no longer recommended . caravan der Knaap ’s sodium remover ' Natrex ' selectively extracts the atomic number 11 that is present in the drain water , allowing for the waste pipe urine to continue to be reuse . The crop tribute products and other useful nutritionary component do stay in the system .
How it worksThe organization is based on the breakup of atomic number 11 from valuable nutrients . This is attain through a sequence of techniques where dissimilar element can be filter and separate from each other . An acidic solution of atomic number 11 and chloride remains as a waste matter stream . This is collected by Van der Knaap and then used in other industries to neutralize alkaline water supply flows . This cognitive process is altogether circular ; nothing goes to waste . The system is adapt to the situation of the grower , whereby the sodium peak remains below the equipment casualty threshold . This will differ per harvest and can be determined in audience with the grower .
Effect of sodium on cultivationSome crops are more raw to sodium than others . Van der Knaap has been search the personal effects of sodium on various craw for several years now . In 2021 , research was carried out in quislingism with Wageningen University & Research into the minus consequence of Na on the production and quality of a sweet white pepper crop . Cultivation was monitored for a yr , during which one-half of the flora in the trials were given a high-pitched sodium content . The other one-half of the plants did not receive Na at all . This test register that it is good to keep the sodium contentedness low .
benefit of NatrexWith Natrex , the grower can abide by with regulations and also save on plant food because other utile elements rest usable in the system . In addition , research shows that the sodium content can also work the growth and caliber of the crop and the harvested product .
