Polyacrylamide, e kiia nei ko te PAM, he pūmua taumaha-ngota teitei. Nā tōna hanganga matū ahurei, e whakamahia whānuitia ana te PAM i roto i ngā ahumahi maha. I roto i ngā mara pēnei i te maimoatanga wai, te hinu, te keri me te hanga pepa, ka whakamahia te PAM hei whakapūmau whai hua hei whakapai ake i te kounga o te wai, hei whakanui ake i te whai huatanga o te keri, me te whakapai ake i te kounga o te pepa. Ahakoa he iti te wairewa o te PAM i roto i te wai, mā roto i ngā tikanga whakarewa motuhake, ka taea e tātou te whakarewa pai i roto i te wai kia whai hua ai i roto i ngā tono ahumahi. Me aro ngā kaiwhakahaere ki ana tohutohu whakahaere motuhake i mua i te whakamahinga. me ngā whakatūpato hei whakarite i te whai huatanga o te hua me te haumaru whaiaro.
Te āhua me ngā āhuatanga matū o te Polyacrylamide
Ko te tikanga, ka hokona ngā PAM i roto i te ahua paura, i te ahua whakaehu rānei. Ko te paura PAM parakore he paura ma ki te kowhai mārama, he paku waikura. Nā te taumaha ngota me te matotoru teitei, ka puhoi te memeha o te PAM ki te wai. Me whakamahi i ngā tikanga memeha motuhake ina memeha ana te PAM kia tino memeha katoa ki te wai.
Me pēhea te whakamahi i te PAM
I te wā e whakamahi ana koe i te PAM, me whiriwhiri tuatahi koe i tētahitikaKaiwhakarewa waimengā whakaritenga e tika ana kia rite ki ngā horopaki me ngā hiahia o te tono. Tuarua, he mea tino tika kia whakahaerehia he whakamātautau ipu me ngā tauira wai me te flocculant. I te wā o te tukanga flocculant, me whakahaere te tere me te wā whakaoho kia whiwhi ai i te pānga flocculant pai rawa atu. I taua wā anō, me tirotiro tonu te horopeta o te flocculant me te whakatikatika kia tutuki ai ngā whakaritenga i te kounga o te wai me te keri me ētahi atu tawhā tukanga. Hei tāpiri, kia aro nui ki te pānga tauhohenga o te flocculant i te wā e whakamahia ana, ā, me mahi i ngā mahi i te wā tika hei whakatikatika mēnā ka puta he āhuatanga rerekē.
Kia pēhea te roa ka pau i muri i te whakarewatanga?
Kia rewa katoa te PAM, ko te pāmahana me te mārama te mea nui hei pānga ki tōna roanga whai huatanga. I te pāmahana rūma, ko te wā whai huatanga o te otinga PAM he 3-7 rā te nuinga, i runga i te momo PAM me te kukū o te otinga. Ā, he pai ake te whakamahi i roto i ngā hāora 24-48. Tērā pea ka ngaro te whai huatanga o te otinga PAM i roto i ētahi rā mena ka roa te wā e pāngia ana e te rā. Nā te mea, i raro i te mahi a te rā, ka whati pea ngā mekameka ngota PAM, ka heke ai tōna pānga pupuhi. Nō reira, me penapena te otinga PAM rewa ki tētahi wāhi hauhautanga, ā, me whakamahi wawe tonu.
Ngā Whakatūpato
Me aro atu koe ki ēnei mea ina whakamahi ana koe i te PAM:
Ngā Take Haumaru: I te wā e whakamahi ana i te PAM, me mau ngā taputapu tiaki whaiaro e tika ana, pērā i ngā mōhiti tiaki matū, ngā koti taiwhanga, me ngā karapu tiaki matū. I taua wā anō, karohia te pa tika o te kiri ki te paura, ki te otinga rānei o te PAM.
Ngā Maringi me ngā Rehu: Ka tino pahekeheke te PAM ina honoa ki te wai, nō reira kia tino tupato kia kore ai e maringi, e rehu nui rawa rānei te paura PAM ki runga i te whenua. Mēnā ka maringi, ka rehuhia rānei, ka pahekeheke pea te whenua, ā, ka tūpono pea ki te haumaru o ngā kaimahi.
Te horoi me te pā: Ki te pāngia ō kākahu, ō kiri rānei e te paura PAM, kaua e horoia tika ki te wai. Ko te muru mārire i te paura PAM ki te tauera maroke te tikanga haumaru.
Te Rokiroki me te Paunga: Me rongoa te PAM kirikiri ki roto i tētahi ipu ārai mārama, kia matara atu i te rā me te hau, kia mau tonu ai tōna whai huatanga. Mēnā ka roa te pānga ki te rā me te hau, ka pakaru pea te hua, ka pirau rānei. Nō reira, me whiriwhiri ngā tikanga tākai me te rokiroki tika hei whakarite i te kounga me te pumau o te hua. Mēnā ka kitea he kore mana, he paunga rānei te wā o te hua, me whakatika wawe, ka whakakapia ki tētahi hua hou kia kore ai e pā ki te whakamahinga noa me te haumaru. I taua wā anō, me aro nui ki te tirotiro i te roa o te oranga o te hua me te whakaū i tōna whai huatanga i mua i te whakamahinga mā roto i ngā whakamātautau, i ngā tirotiro rānei e tika ana, kia tino tutuki ai ngā whakaritenga paerewa.
