He aha ngā pūmua e whakamahia ana hei whakapūkara?

Ko tētahi wāhanga matua o te tukanga maimoatanga waipara ko te whakapūmau me te whakatau i ngā totoka i whakatārewatia, he tukanga e whakawhirinaki ana ki ngā matū e kiia neingā mea whakapūkaraI roto i tēnei, he mahi nui tā ngā pūmua, nō reira ko te PAM, ko ngā polyamine. Ka rukuhia e tēnei tuhinga ngā pūmua waipara noa, te whakamahinga o ngā pūmua hei waipara i roto i te maimoatanga waipara, me ngā mahi kei muri i a rātou.

He aha ngā mea e whakamahia whānuitia anangā mea whakapūkara polymer?

Ko ngā matū whakapūkara polymer e whakamahia whānuitia ana ko ngā polymer cationic, ngā polymer anionic me ngā polymer nonionic. Ka taea te whiwhi i ēnei polymer mā roto i ngā tikanga hanga rerekē, ā, he rerekē ngā hanganga cationic me ngā hanganga peka. I roto i ngā tono mahi, me whiriwhiri ngā matū whakapūkara polymer e tika ana kia rite ki ngā āhuatanga motuhake o te wai para kia whiwhi ai i te pānga maimoatanga pai rawa atu. Ko te PAM, polyDADMAC, e whakamahia whānuitia ana i roto i te maimoatanga wai para ahumahi. Ko te Polyacrylamide te matū whakapūkara e whakamahia whānuitia ana i te ao. He mea hanga ēnei polymer wairewa-wai, ā, ka taea te hanga ritenga mō ngā tono motuhake mā roto i ngā taumaha ngota ngota rerekē, ngā matotoru, ngā nekehanga utu rerekē, ngā āhua rerekē pērā i ngā matūriki, ngā emulsion, me ētahi atu. E whakamahia whānuitia ana te PolyDADMAC i roto i te wai tap, te whakapūkara wai mata, te whakamaroke paru, te ahumahi pepa me te ahumahi tā me te tae.

Te whakamahinga ongā mea whakapūkara i roto i te maimoatanga wai para

Ko te whāinga matua o te maimoatanga wai para ko te tango i ngā poke pēnei i ngā totoka iri, ngā mea rauropi rewa me ngā matūriki korōria mai i te wai hei whakapai ake i te kounga o te wai. I roto i tēnei tukanga, he mahi nui tā ngā mea whakapūpū. Mā te whakamahi i ngā mea whakapūpū, ka taea te whakakotahi i ngā matūriki ririki me ngā matū korōria i roto i te wai hei ngā mea nui ake, ka taea te tango ngāwari atu mā te whakatōpuku, te tātari rānei. Ehara i te mea ka whakapai ake i te kounga o te wai anake, engari ka whakapai ake hoki i te whai huatanga o te maimoatanga me te whakaiti i ngā utu maimoatanga.

He aha ngā polymers ka taea ai te hanga flocculants?

Ka taea te whakamahi i ngā pūmua hei whakapūpū i te wai nā te mea he nui te taumaha ngota me te hanganga maha-manga. Mā ēnei āhuatanga ka pai ake te mimiti o te pūmua ki runga i ngā matūriki, ka hanga he pūmua nui ake ka tere te tau. Hei tāpiri, ka taea e ngā pūmua te whakakore i te pana hiko i waenga i ngā matūriki mā te whakakore i te utu, ka taea ai e ngā matūriki te whakatata mai me te whakakotahi ngātahi.

Te tikanga mahi a ngā pūmua i roto i te maimoatanga wai para

Ka taea te wehewehe i te tikanga mahi a ngā pūmua hei whakapūpū i ngā matūriki kia toru ngā taahiraa: te whakakore i te utu, te whakapūpū i te whakapūpū me te hopu kupenga. Tuatahi, ka whakakorea e te pūmua te ātete hiko i waenga i ngā matūriki mā te whakakore i te utu, ka taea ai e ngā matūriki te whakatata mai. Kātahi ka honoa e te pūmua ngā matūriki kia hanga he whakapūpū nui ake mā te whakapūpū i te whakapūpū. Hei whakamutunga, ka whakakotahihia anō ēnei whakapūpū ka whakatōkia ki roto i te wai mā te mahi horapa o ngā kupenga.

Ngā āhuatanga e pā ana ki te whai huatanga o ngā Polymers i roto i te maimoatanga o te wai para

He maha ngā āhuatanga e pā ana ki te whai huatanga o te tukatuka polymer i te wai para, tae atu ki te momo polymer, te inenga, te uara pH, te pāmahana, te tere whakaoho, me ētahi atu. I roto i ēnei, ko te momo polymer me te inenga tētahi o ngā āhuatanga tino nui. He rerekē ngā āhuatanga utu me ngā tohatoha taumaha ngota o ngā momo polymer, nō reira me whiriwhiri te momo polymer me te inenga tika mō ngā wai para rerekē kia tutuki ai te pānga maimoatanga pai rawa atu. Hei tāpiri, ko ngā āhuatanga pēnei i te uara pH, te pāmahana, me te tere whakaoho ka pā ki te whai huatanga o te maimoatanga, ā, me whakatau ngā āhuatanga tino pai mā roto i ngā whakamātautau.

He mea nui te mahi a ngā pūmua hei whakapūpū i roto i te maimoatanga waipara. Mā te māramatanga hōhonu ki te tikanga mahi me ngā āhuatanga awe o ngā pūmua ka taea te whakarato tautoko ariā me te aratohu mahi mō te arotau i ngā tukanga maimoatanga waipara me te whakapai ake i te whai huatanga o te maimoatanga. I te heke mai, me te whakapai tonu i ngā whakaritenga tiaki taiao me te whanaketanga tonu o te pūtaiao me te hangarau, e whakaponohia ana ka whānui ake, ka hohonu ake te whakamahinga o ngā pūmua i roto i te maimoatanga waipara.
