Imeko yeshishini kunye neempawu zamanzi amdaka e-tannery
Kubomi bemihla ngemihla, iimveliso zesikhumba ezifana neengxowa, izihlangu zesikhumba, iimpahla zesikhumba, iisofa zesikhumba, njl.njl. zixhaphakile. Kwiminyaka yakutshanje, ishishini lesikhumba liye lakhula ngokukhawuleza. Kwangaxeshanye, ukukhutshwa kwamanzi amdaka e-tannery kuye kwaba ngomnye wemithombo ebalulekileyo yongcoliseko lwemizi-mveliso.
Ukushushuluza ngokuqhelekileyo kubandakanya amanqanaba amathathu okulungiselela, ukushushuluza kunye nokugqiba. Kwicandelo lokulungiselela ngaphambi kokushushuluza, amanzi amdaka avela kakhulu ekuhlanjweni, ekufakweni emanzini, ekususweni koboya, ekufakweni kwelayisi, ekususeni i-liming, ekuthambiseni nasekususeni amafutha; izinto ezingcolisayo eziphambili ziquka inkunkuma yendalo, inkunkuma engaphiliyo kunye neekhompawundi zendalo. Amanzi amdaka kwicandelo lokushushuluza ngokuqhelekileyo avela ekuhlanjweni, ekufakweni kwe-pickling, nasekushutyweni kwe-tan; izinto ezingcolisayo eziphambili ziityuwa ezingaphiliyo kunye ne-chromium yesinyithi esinzima. Amanzi amdaka kwicandelo lokugqiba ngokuqhelekileyo avela ekuhlanjweni, ekucinezelweni, ekudayweni kwedayi, ekufakweni amafutha kunye nasekususeni uthuli lwe-tan, njl. Izinto ezingcolisayo ziquka iidayi, iioyile kunye neekhompawundi zendalo. Ke ngoko, amanzi amdaka e-tannery aneempawu zomthamo omkhulu wamanzi, ukuguquguquka okukhulu kumgangatho wamanzi kunye nomthamo wamanzi, umthwalo ophezulu wongcoliseko, i-alkalinity ephezulu, i-chroma ephezulu, umxholo ophezulu wezinto eziqinileyo ezixhonyiweyo, ukubola okuhle, njl., kwaye anobuthi obuthile.
Amanzi amdaka anesalfure: Ulwelo lwenkunkuma yelami oluveliswa kukucocwa koboya yi-ash-alkali kwinkqubo yokuthambisa kunye namanzi amdaka ahambelana nenkqubo yokuhlamba;
Ukususa igrisi emanzini amdaka: Kwinkqubo yokususa igrisi yokwenziwa kwesikhumba kunye nokulungiswa koboya, ulwelo lwenkunkuma lwenziwa ngokunyanga ulusu oluluhlaza kunye neoyile nge-surfactant kunye namanzi amdaka afanelekileyo okuhlamba.
Amanzi amdaka aqulethe iChromium: utywala obuvela kwi-chrome tanning kunye neenkqubo zokubuyisela i-chrome tanning, kunye namanzi amdaka ahambelanayo kwinkqubo yokuhlamba.
Amanzi amdaka apheleleyo: ligama eliqhelekileyo lamanzi amdaka ahlukeneyo aveliswa ziinkampani zokucoca nokulungisa uboya okanye iindawo zokucubungula ezikwindawo enye, aze akhutshwe ngokuthe ngqo okanye ngokungathanga ngqo kwiiprojekthi zokucoca amanzi amdaka apheleleyo (ezifana namanzi amdaka enkqubo yokuvelisa, amanzi amdaka asekhaya kwiifektri).
