Implementation of the Water Framework Directive in 2018 impose limits to Dutch raiser for discharge drain water into gutter and surface weewee . But , as the amount of sodium will build up , never-ending recirculation of irrigation body of water is merely not an choice . An matter that is also progressively occurring across borders . " In the last two summers , this was compromising the calibre of our crops , " says Koen Saris , operations coach of Wijnen Square Crops . Having had positive experiences with one Poseidon organization of Moor Filtertechniek ( part of Van der Ende Groep ) , this odorous pepper and cucumber grower of Grubbenvorst in the Netherlands append two more unit . The Poseidon water supply handling organization effectively egest sodium , while retaining worthful nutrient .
progressively stringent measure relating to the discharge of drain piss are not just for Dutch growers . Also internationally , systems like the Poseidon are a relevant and interesting investiture and therefore demand has grown rapidly . The water treatment system made its debut at Wijnen Square Crops in 2018 . " We use spring water at one of our sweet pepper location . It does n’t have a particularly high concentration of sodium , but the new police force and regulations for re - using weewee signify that the sodium concentration accumulates during the time of year . We therefore bought a Poseidon , " explains operation manager Koen Saris .
Different rain patternThe companionship has three locations – two 11 - hectare and one 10 - hectare – and initially they all took turns with the one Poseidon system . " found on the water depth psychology , we go the system to the location where it was needed . The capacity should have been sufficient , but we ’ve noticed over the last few years that the quantity of rain has changed . There ’s less rainfall and when it does really rain , it fall in short point . This meant we did n’t always have enough rain available . We started using more spring water , but the atomic number 11 is n’t soak up by the plant , so it build up up and the atomic number 11 spirit level of the water increases . We had high sodium floor the last two summers , and it was compromising product and the quality of our crops . "
pull out sodium at minimum costThat was when Wijnen Square Crops decided that each of the three locating should have its own Poseidon with sufficient capacity . The system uses several different techniques to make pure pee : ultrafiltration , nanofiltration , reverse osmosis and active carbon . It also has a newspaper swath filter to off the first ‘ uncouth ’ contaminants . And a Poseidon not only extracts sodium at minimum cost : its capacity can also be tailor-make specifically for each client .
loanblend systemThe Poseidon has an extra function at Wijnen Square Crops : it is no longer used exclusively as a water handling organisation , but also as a disinfection system . To fulfill this function , the three Poseidons have been outfit with the in - firm developed disinfection technology of Moor Filtertechniek . Thanks to the addition of ultrafiltration , the Poseidon now also eliminates bacterium , fungi and viruses . Koen Saris is pleased with the cross solution : " We already had a ultraviolet disinfection arrangement at one of our sites . However , it had n’t been working by rights , so we switched if off and did n’t use it any more . We have an ozone system as well , but the Poseidon ’s operating cost are a number low . So the Poseidon also has fiscal advantages . "
