Igipimo cyo gusaba:Urukurikirane rwa GYW vacuum ihoraho ya magnetiki ni ubwoko bwa silinderi yo hanze yo kuyungurura vacuum ihoraho ya magnetiki iyungurura hamwe no kugaburira hejuru, ikaba ikwiriye cyane cyane kubura umwuma wibikoresho bya magneti hamwe nuduce duto duto.
Igipimo gikoreshwa:Ikoreshwa cyane mu biyaga binini, ibigega, ahantu nyaburanga, amazi, imyanda yo mu mijyi, kugirango ikureho eutrophasi ya azote, fosifore na cyanobacteria.
