Ukucocwa kwamanzi amdaka kwimizi-mveliso – iiFlocculants (PAM)

Kumanzi amdaka akwimizi-mveliso, maxa wambi kukho ukungcola okwenza amanzi abe namafu, nto leyo eyenza la manzi amdaka kube nzima ukuwacoca.Kuyimfuneko ukusebenzisa i-flocculant ukwenza amanzi acace ukuhlangabezana nomgangatho wokukhutshwa.Kule flocculant, sincomai-polyacrylamide (PAM).

I-Flocculantyokucoca amanzi amdaka kwimizi-mveliso

I-Polyacrylamide yipolima enyibilikayo emanzini.Ikhonkco layo lemolekyuli liqukethe amaqela e-polar, anokuthi adsorb amasuntswana axhonywe kwisisombululo kwaye adibanise amaqhekeza ukuze enze iiflocs ezinkulu.Iiflocs ezinkulu ezenziweyo zinokukhawulezisa imvula yeengqungquthela ezimisiweyo kwaye zikhawuleze umphumo wokucaciswa kwesisombululo.Xa kuthelekiswa nonyango oluqhelekileyo lwamanzi amdaka, unyango lwamanzi amdaka amachiza lunzima kakhulu.Kwinkqubo yokunyanga amanzi amdaka amachiza, ii-agent ezahlukeneyo ezifana ne-flocculants, coagulants, kunye ne-decolorizers ziyafuneka.Phakathi kwazo, i-flocculant esetyenziswa ngokuqhelekileyo yi-nonionic polyacrylamide.

Indlela yophuhliso ye-polyacrylamide

1. Ikhonkco lemolekyuli ye-polyacrylamide iqulethe amaqela e-polar, anokuthi afunxe amasuntswana axhonywe emanzini kunye nebhulorho phakathi kwamasuntswana ukwenza iiflocs ezinkulu.

2. I-polyacrylamide engekho i-ionic inokukhawulezisa imvula yeengqungquthela ezimisiweyo ngokwenza iiflocs ezinkulu, ngaloo ndlela ikhawuleza ukucaciswa kwesisombululo kunye nokukhuthaza umphumo wokucoca.

3. Phakathi kwazo zonke iimveliso ze-flocculant, i-polyacrylamide engeyiyo i-ionic inefuthe elihle ekuphatheni amanzi amdaka ane-asidi, kwaye amanzi amdaka ekhemikhali ngokubanzi aneasidi.Ke ngoko, i-polyacrylamide engeyiyo ionic ineengenelo zayo ezizodwaunyango lwamanzi amdaka ngemichiza.

4. I-coagulant ingasetyenziselwa ukudibanisa kunye neetyuwa ze-inorganic ezifana ne-polyaluminium, i-polyiron kunye nezinye i-flocculants ezingabonakaliyo, kwaye umphumo ungcono.Kungenxa kanye ngenxa yeempawu ze-polyacrylamide engeyiyo ionic ukuba ineenzuzo ezicacileyo kunyango lwamanzi amdaka amachiza.

Sinikezela nge-PAM ephezulu yokubonelela ngesandla sokuqala kwifektri, ukuze ufumane i-PAM enexabiso eliphantsi kunye namava anelisayo emva kokuthengisa.
