It is ( or in reality ‘ was ’ ) a challenge to remove Na from water and , at the same fourth dimension , to retain as many nutrients as potential . Van der Ende Groep germinate the Poseidon to meet the above task , and it was reach - the first 20 installing have now been put into operation .
agriculturalist chiefly focus on the Na mental object . Micha van Nieuwkerk from Van der Ende Group : " They are seeing a sharp drop in sodium levels . So that amply meets the expectations . An additional reward of Poseidon is that less has to be discharge . In the dry class of 2018 , that worked out well for many users . They did not have to grapple with a piddle shortage . Poseidon therefore save water in compare with the former situation . "
comparative removalEvery day Poseidon bump off part of the sodium that is present in the water system . In this way the atomic number 11 content is reduced in footstep . The most common type of Poseidon are 8 - 1 , 8 - 2 and 8 - 3 . Each case is significative of the capacity . The sodium remotion percentages then look as follows with different silo content : Table 1 : Sodium removal in % per sidereal day
The hardheaded effect looks like this for Poseidon 8 - 2 with a silo content of 400 m3 : Table 2 : Example of atomic number 11 decrease per twenty-four hour period in a week
Nutrient retentionThe roots of the flora take up the nutrients . The leave nutrient are dissolve in the body of water . Naturally , the raiser does not require to lose what was ab initio not absorbed . Poseidon is focusing on this , Micha says . " The installation employ a special membrane engineering . This removes sodium from the drainage water while retain as many nutrients as possible . This is possible because sodium has a unlike constituent size : the nano filtration tissue layer allow Na through and hold back the nutrients . This is how the elements can be separated from each other . “Table 3 : Saving on nutrient
Zero emissionIn 2027 , the government will call for zero emission from agriculturalist . Employees from Van der Ende Group are proactive on this ; the product developments are in full swing . Micha : " The next pace is to take in even less discharge . "
