Good irrigation water supply and surface water is vitally of import to growers and their crops . Both the availability and character of the H2O are under press in many places . Closed urine systems that reuse ( disinfected ) waste pipe water can be part of the result .

Recirculation and sodium"Work is being done on this in many country and regions , " theater director Freek van Rijn explains . " The point is , however , that most crop do n’t engulf much sodium , so the sodium tightness in close system step by step increase . At some point , you would have to fire that water . If you ’re not permitted to or do n’t want to do that , our Sorem atomic number 11 removal unit can propose a solution . It was developed especially for that use . "

The SOREM atomic number 11 removal unit appeal a batch of attending at the Van Dijk Heating stall at the GreenTech trade just in Amsterdam ( June 2022 ) . Growers are clearly concerned in this technology , a sustainable solution that make it possible to keep recirculating drain water for much longer .

Operating procedureThe remotion process is based on ion rally by means of a resin column and additive . During the process , the additives ( nitric loony toons , caustic potash , and CO2 ) are converted into potassium nitrate , a standard fertiliser .

The unfastened structure give the resin column a magnanimous alive surface , which binds a lot of Na . As shortly as the intensity point is touch , the rosin column is " discharged " in a separate process stage . The concentrated Na solution drain into the sewer . Most of the additives remain behind in the system , where they make a second part as a nutrient constituent in the form of potassium nitrate . This means that the net use of additives is extremely down .

CertificationOnce the system is approved by the Dutch Assessment Committee for Greenhouse Water Purification Installations , the SOREM will be ready for commercial-grade use . The paradigm first has to be modified slightly to ensure that any craw aegis factor residues have been sufficiently broken down . In the Netherlands , this is a essential if you are going to drop residual water into the sewer .

" When that adjustment is made , a new , very extensive mental testing cycle will stick with , as usual , " Van Rijn adds . " Neither we nor the certification torso want to give anything to chance . I do n’t dare prefigure how long it will take all together , but we ’re very convinced in a good outcome . Then Na no longer has to be an obstruction to completely shut down cultivation . "
