Aliyense amadziwa kuti madzi ambiri amafunikira pokonza zinthu za soya, choncho n'zosapeŵeka kuti zimbudzi zidzapangidwa.Choncho, mmene kuchitira zimbudzi wakhala vuto lovuta kuti soya mankhwala processing mabizinesi kukumana.
Pakukonza zinthu za soya, madzi ambiri onyansa amapangidwa, omwe amagawidwa m'magawo atatu: kuthira madzi, madzi oyeretsera opanga, ndi madzi achikasu achikasu.Ponseponse, kuchuluka kwa madzi oyipa omwe amatayidwa ndiakuluakulu, okhala ndi zinthu zambiri zakuthupi, kapangidwe kake kovutirapo, komanso COD yayikulu.Kuphatikiza apo, kuchuluka kwa madzi oyipa omwe amapangidwa pokonza zinthu za soya kumatha kusiyanasiyana kutengera kukula kwa bizinesiyo.
Malinga ndi zomwe makasitomala amafuna, kapangidwe kameneka kamatengera njira yoyatsira mpweya.Njira yoyandama mpweya imagwiritsa ntchito thovu ting'onoting'ono ngati zonyamulira kuti zitsatire ndikuchotsa mafuta ang'onoang'ono ndi zolimba zoyimitsidwa m'madzi onyansa, kukwaniritsa kuyeretsedwa koyambirira kwamadzi, kupanga mikhalidwe yabwino yamagulu azotsatira zamankhwala am'thupi, ndikuchepetsa kuchuluka kwamankhwala kwa magawo azotsatira a biochemical.Zowononga zomwe zili m'zimbudzi zimagawidwa m'magulu osungunuka ndi zinthu zosasungunuka (SS).Nthawi zina, zinthu zosungunuka zimatha kusinthidwa kukhala zinthu zosasungunuka.Imodzi mwa njira zochizira zimbudzi ndikuwonjezera ma coagulants ndi ma flocculants kuti asinthe zinthu zambiri zomwe zasungunuka kukhala zinthu zosasungunuka, ndikuchotsa zonse kapena zinthu zambiri zosasungunuka (SS) kuti akwaniritse cholinga choyeretsa zimbudzi. njira kuchotsa SS ndi ntchito mpweya flotation.Pambuyo pa mlingo wa dosing, madzi otayira amalowa m'dera losakanikirana la mpweya woyendetsa mpweya ndipo amakumana ndi madzi osungunuka omwe amamasulidwa, zomwe zimapangitsa kuti ma flocs amamatire ku thovu labwino asanalowe m'dera la air flotation.Pansi pa kuchitapo kwa mpweya, timagulu tating'ono timayandama pamwamba pamadzi kuti tipange zinyalala.Madzi oyera omwe ali m'munsi mwake amapita ku thanki yamadzi oyera kudzera m'chotolera madzi, ndipo gawo lina lake limabwereranso kukagwiritsidwa ntchito gasi wosungunuka.Madzi oyera otsalawo amatuluka kudzera padoko losefukira.Pambuyo pa slag yoyandama pamadzi a thanki yoyandama ya mlengalenga ikafika pa makulidwe ena, imakankhidwira mu thanki ya flotation sludge ndi chofufutira thovu ndikutulutsa.
