Unyango lwamanzi amdaka kwimizi-mveliso – iiFlocculants (PAM)

Kwimithombo yamanzi amdaka, ngamanye amaxesha kukho ukungcola okwenza amanzi abe namafu, nto leyo eyenza la manzi amdaka abe nzima ukuwacoca. Kubalulekile ukusebenzisa i-flocculant ukuze amanzi acace ukuze ahlangabezane nomgangatho wokukhupha. Kule flocculant, sicebisai-polyacrylamide (PAM).

I-Flocculantunyango lwamanzi amdaka kwimizi-mveliso

I-Polyacrylamide yi-polymer enyibilikayo emanzini. Ikhonkco layo le-molecular liqulathe amaqela e-polar, anokufunxa amasuntswana axhonywe kwisisombululo aze adibanise amasuntswana ukuze enze ii-flocs ezinkulu. Ii-flocs ezinkulu ezenziweyo zinokukhawulezisa ukuna kweesuntswana ezixhonyiweyo kwaye zikhawulezise isiphumo sokucaciswa kwesisombululo. Xa kuthelekiswa nonyango oluqhelekileyo lwamanzi amdaka, unyango lwamanzi amdaka ngamakhemikhali luyinkimbinkimbi kakhulu. Kwinkqubo yokunyanga amanzi amdaka ngamakhemikhali, kufuneka izinto ezahlukeneyo ezifana nee-flocculants, ii-coagulants, kunye nee-decolorizers. Phakathi kwazo, i-flocculant esetyenziswa kakhulu yi-nonionic polyacrylamide.

Indlela yophuhliso lwe-polyacrylamide

1. Ikhonkco leemolekyuli ze-polyacrylamide liqulathe amaqela e-polar, anokufunxa amasuntswana axhonywe emanzini aze adibanise amasuntswana ukuze enze ii-flocs ezinkulu.

2. I-polyacrylamide engeyiyo i-ionic inokukhawulezisa ukuna kwee-particles ezixhonyiweyo ngokwenza ii-flocs ezinkulu, ngaloo ndlela ikhawulezisa ukucaciswa kwesisombululo kwaye ikhuthaze isiphumo sokuhluza.

3. Phakathi kwazo zonke iimveliso ze-flocculant, i-non-ionic polyacrylamide inefuthe elihle ekunyangeni amanzi amdaka ane-asidi, kwaye amanzi amdaka eekhemikhali ahlala ene-asidi. Ke ngoko, i-non-ionic polyacrylamide ineenzuzo zayo ezikhethekileyo kwiunyango lwamanzi amdaka ngamakhemikhali.

4. I-coagulant ingasetyenziswa kunye neetyuwa ezingaphiliyo ezifana ne-polyaluminum, i-polyiron kunye nezinye ii-flocculants ezingaphiliyo, kwaye isiphumo singcono. Kungenxa yeempawu ze-non-ionic polyacrylamide ukuba ineenzuzo ezicacileyo ekunyangweni kwamanzi amdaka eekhemikhali.

Sibonelela nge-PAM esemgangathweni ophezulu ukuze ufumane imveliso ethengiswa ngqo kumzi-mveliso, ukuze ufumane i-PAM engabizi kakhulu kunye namava amnandi emva kokuthengisa.
