Umhlinzeki we-HPAA (2-Hydroxy Phosphonoacetic Acid) eNingizimu Afrika

Isivimbeli esisezingeni eliphansi kanye nesivimbeli sokugqwala sezinhlelo zamanzi okupholisa ezimbonini kanye namanzi ase-oyili — sisebenza kahle kakhulu ekuvimbeleni isikali se-calcium carbonate, i-calcium sulfate, kanye ne-calcium phosphate ngemithamo ephansi kakhulu.

Kuyini i-HPAA?

I-2-Hydroxy phosphonoacetic acid (HPAA) iyisivimbeli se-organophosphonic acid scale inhibitor esinesakhiwo sama-molecule esiqukethe iqembu le-hydroxyl kanye neqembu le-phosphonic acid. Iphakathi kwezivimbeli ze-low-threshold scale ezisebenza kahle kakhulu emndenini wamakhemikhali okwelapha amanzi - ivimbela ukwakheka kwesikali ngamanani angaphansi kakhulu kwenani le-stoichiometric elidingekayo ukuze kuhlanganiswe wonke ama-ion scaling, isici esaziwa ngokuthi "umphumela we-threshold." I-HPAA isebenza kahle kakhulu ekuvimbeleni isikali se-calcium carbonate (CaCO₃) - uhlobo lwesikali oluvame kakhulu ezinhlelweni zamanzi okupholisa - kanye nokwakheka kwesikali se-calcium sulfate (CaSO₄) kanye ne-calcium phosphate (Ca₃(PO₄)₂) kumasekethe amanzi ezimboni.

Izicelo Zamanzi Okupholisa kanye Namanzi Ezimboni

Ezinhlelweni zamanzi okupholisa ezijikelezayo ezivulekile, i-HPAA isetshenziswa ku-2–10 mg/L ukuvimbela ukufakwa kwesilinganiso se-calcium carbonate kanye ne-calcium sulfate ezindaweni zokushintshanisa ukushisa kanye nezindonga zamapayipi, kugcinwa ukusebenza kahle kokudlulisa ukushisa futhi kuvimbele ukugqwala okungafakwanga kahle. Ihambisana nezivimbeli zokugqwala ezisetshenziswa kakhulu (i-zinc, i-molybdate, i-polyphosphate) kanye ne-biocides (i-oxidising kanye ne-non-oxidising) ezisetshenziswa ezinhlelweni zokwelashwa kwamanzi okupholisa. I-HPAA iyasebenza ebangeni elibanzi le-pH (6–9) kanye nasezingeni lokushisa eliphakeme (kufika ku-70–80°C), okwenza ifaneleke kokubili ukusetshenziswa kwesekethe elizungezile kanye nelisezingeni lokushisa eliphezulu.

Izicelo Zamanzi Ezindaweni Zamafutha Nezinye Izindawo Zokusebenza

Ekufakweni kwamanzi endaweni kawoyela kanye nasekuphathweni kwamanzi okukhiqizwayo, i-HPAA isetshenziselwa ukuvimbela isikali se-calcium carbonate kanye ne-barium/strontium emithonjeni yokugaya kanye nasezindaweni ezingaphezulu. Ingasetshenziswa njengesivimbeli sesikali esizimele noma emaphaketheni okuvimbela ahlanganisiwe. I-Terracore Chemicals inikeza i-HPAA njengesixazululo samanzi esingaba ngu-50% kuma-drum angu-25 kg kanye no-200 kg emisebenzini yokwelapha amanzi kulo lonke elaseNingizimu Afrika.

Izicelo
