By 2027 , Dutch growers will have to work with ( near ) zero emissions . It is a Modern dot on the purview after a zero discharge demand had already been introduced on 3 February 2025 . This was ab initio supposed to be in 2021 . Some growers were surprised by the early introduction .
For Van Dijk Heating , too , the debut came rather than expected . They do n’t want this surprisal to happen again . That is why the company is already fully commit to a sodium eliminator , despite the fact that the sound necessity still seems relatively far forth .
A prototype of this system of rules , which goes by the name of Sorem , has been range at a Dutch capsicum pepper plant grower since the goal of last yr . The organization must fill in the picture for water intervention because , with the Ecoster , Van Dijk Heating already has a drain water disinfector on the market for many years . Joek van der Zeeuw , Sales Manager at Van Dijk heating : " A sodium eliminator like this is an absolute necessary for growers who are going to work in a closed in system to reprocess their drainpipe weewee . "
RemovalThe removal process is base on ion telephone exchange using a resin column and additive . The additives ( nitric acid , caustic caustic potash and CO2 ) are converted into K nitrate , a common plant food .
The open structure gives the resin pillar a big active surface , which binds a mountain of sodium . As soon as the saturation point is reach , the resin editorial is “ discharged ” in a separate process stage . The concentrated sodium solution drain into the sewer . Most of the additives stay behind in the organisation , where they make a 2nd share as a nourishing component in the form of K nitrate . " The net usance of additives is therefore very low , " says Joek .
On ordinary , one unit is enough to keep the water system scheme on a 10 - hectare farm sodium - free and closed .
In late years , the focal point in term of water reuse was mainly on viruses . With the Ecoster from Van Dijk heating , which make for on the basis of heating , agriculturist combat viruses . Joek : " The principle of heating has existed for a foresightful time , and we have been using it successfully in gardening for over thirty years . Even with the emergence of new technology , we have noticed that there is a group of growers who continue to opt for heating , on the nose because it is such a uncomplicated principle that is easy to understand . "
However , now that growers want to recirculate drainage water , an extra facility is needed . With a Sorem sodium eliminator , Van Dijk heating plant is choke to offer growers such an installation under their own direction . They will present the organisation at GreenTech in Amsterdam in June . Van Dijk Heating can be found at GreenTech at standstill 01.542 .
