Sezvo nzvimbo dzokuredza hove dziri munyika yose dziri pedyo kana kuti kupfuura miganhu isingachinjiki, uye zvino kurudziro dzoutano dzinokurudzira kuwedzera kudyiwa kwehove dzine mafuta kuti dzibatsire kudzivirira hosha yemwoyo, hurumende dziri kunyevera kuti nzira bedzi yokugutsa nayo kudiwa kwevatengi kupfuurira kukura kwemhuka yegungwa.
Nhau dzakanaka ndedzekuti mapurazi ehove anogona kuwedzera mashizha ehove nekuvandudza goho kusvika pachikamu chimwe chete muzvitatu nekutsanangura mashandisirwo ePSA okisijeni kubva kune nyanzvi yekuparadzanisa gasi Sihope, iyo inogona kuunza oxygen kumatangi ehove mune yayo yakachena.Mabhenefiti ekugadzirwa kweokisijeni anonyatsozivikanwa mukati meiyo aquaculture indasitiri: hove dzinoda kanenge 80 muzana oksijeni saturation mumvura kuti optimize kukura.Kusakwana kweokisijeni mazinga anokonzera kusagaya zvakanaka muhove, zvekuti dzinoda chikafu chakawanda uye njodzi yekurwara inowedzerawo.
Nzira dzakajairwa dzeokisijeni dzinobva pakuwedzera kwemhepo chete dzinokurumidza kusvika padzinogumira nekuti, kunze kweiyo 21 muzana yeokisijeni ine mweya, mweya inewo mamwe magasi, kunyanya nitrogen.Ichishandisa tekinoroji yakafanana neiyo inoshandiswa munzvimbo dzekurapa, majenereta egasi eSihope anoshandisa Pressure Swing Adsorption kuunza okisijeni yakachena zvakananga mumvura.Izvi zvinogonesa kugadzirwa kwehove zhinji muhuwandu hudiki hwemvura uye zvinoita kuti hove dzikurewo.Izvi zvinoita kuti kunyange makambani madiki akwanise kurima zvakanyanya, zvichiita kuti zvive nyore kwavari kuti vazvisimbise mumamiriro ehupfumi.
Alex yu, maneja wekutengesa weSihope akatsanangura kuti: “Tinopa michina yePSA yezvivakwa zvakawanda pasi rose, kubva kumhuka dzemvura muChina kusvika kunzvimbo yekutsvagisa yeYunivhesiti yeZhejiang.Kuiswa kwedu papurazi rebarramundi kuDarwin kwakaratidza kuti pa1kg yega yega yeokisijeni inopombwa mumvura, 1kg yehove inokura.Majenareta edu parizvino ari kushandiswa kurima salmon, eels, trout, prawns uye snapper pakati pemamwe marudzi, pamwero wepasi rose.
Kunyanya kushanda nesimba kupfuura zvechinyakare paddlewheel midziyo, majenareta eSihope anowedzera kudzvanywa kwechidimbu uye nekudaro muganho wekuzara mumvura nechikamu che4.8 zvichienzaniswa nemhepo nemhepo chete.Kuwanda kweokisijeni kwakakosha, kunyanya sezvo mapurazi ehove mazhinji ari munzvimbo dziri kure.Tichishandisa midziyo yaSihope, mapurazi ehove anogona kuchengetedza mweya weokisijeni wakavimbika mumba kwete kuenderana nekutakura matangi ayo, kana akanonoka, anogona kukanganisa kunaka kwehove yese yepurazi.
Mapurazi anogona kuita imwe mari yekuchengetedza sezvo hutano hwehove uye metabolism inovandudzwa, saka chikafu chishoma chinodiwa.Nekuda kweizvozvo, salmon inorimwa nenzira iyi ine huwandu hwepamusoro hweOmega 3 fatty acids uye inovandudza kunaka kwekunaka.Sezvo kunaka kwemvura kunoratidza kunaka kwehove, midziyo yeSihope inogona zvakare kushandiswa kugadzira ozone inodiwa mumvura inodzoreredza mareactors kuti iorese mvura yakashandiswa - iyo inozogadziriswa nechiedza cheUV isati yadzoserwa mutangi.
Magadzirirwo aSihope anonangana nekusangana nezvinodiwa nevatengi, kuvimbika, kuve nyore kugadzirisa, kuchengetedza, uye kuzvidzivirira kwechirimwa.Iyo kambani inyika inotungamira kugadzira gasi process masisitimu, kune chikepe chengarava uye pasi-based kushandiswa kuenderana chero chinodikanwa.
