pH o te waipara
He nui te pānga o te pH o te paru ki te pānga o ngā mea whakapūkara. E pā ana te uara pH o te paru ki te kōwhiringa o ngā momo mea whakapūkara, te horopeta o ngā mea whakapūkara me te pānga o te totohu me te whakatō. Ina teitei te uara pH<4, he tino ngoikore te pānga totoka. Ina kei waenga i te 6.5 me te 7.5 te uara pH, he pai ake te pānga totoka. I muri i te uara pH >8, ka tino ngoikore anō te pānga toto totoka.
He pānga ārai te kawakore o te wai para ki te uara PH. Mēnā kāore i te rawaka te kawakore o te wai para, me tāpiri he raima me ētahi atu matū hei tāpiri atu. Mēnā he tiketike te uara pH o te wai, me tāpiri he waikawa hei whakatika i te uara pH ki te kūpapa. He rerekē, kāore i te tino pāngia ngā polymer flocculants e te pH.
te pāmahana o te waipara
Ka pā pea te pāmahana o te wai para ki te tere o te rere o te wai whakapūkara. Ina iti te pāmahana o te wai para, ka nui te matotoru o te wai, ā, ka iti te maha o ngā tukinga i waenga i ngā matūriki wai whakapūkara me ngā matūriki poke i roto i te wai, ka ārai i te piri tahi o ngā wai whakapūkara; nō reira, ahakoa ka nui ake te horopeta o ngā wai whakapūkara, ka puhoi tonu te hanganga o ngā wai whakapūkara, ā, he wetewete, he angiangi hoki, ka uaua ki te tango.
ngā poke i roto i te waipara
He pai te rahi koretake o ngā matūriki poke i roto i te wai para mō te whakapūpūtanga; engari, ka hua ake te hua whakapūpūtanga ngoikore i ngā matūriki angiangi me te ōrite. He maha ngā wā ka kino te kukū iti o ngā matūriki poke ki te whakapūpūtanga. I tēnei wā, ka taea e te whakapūpūtanga o te paru, te tāpiri rānei i ngā āwhina whakapūpūtanga te whakapai ake i te hua whakapūpūtanga.
Ngā momo flocculants
Ko te whiriwhiri i te wai whakapūkara e whakawhirinaki ana ki te āhua me te kukū o ngā totoka iri i roto i te wai para. Mena he rite te wai whakapūkara ki te tiēre, me whiriwhiri ngā wai whakapūkara kore-ora hei whakararuraru, hei whakakōkī hoki. Mena he iti ngā wai whakapūkara, me tāpiri ngā wai whakapūkara polymer, me whakamahi rānei i ngā āwhina whakakōkī pērā i te tiēre silica whakahohe.
I roto i te nuinga o ngā wā, ko te whakamahinga ngātahi o ngā flocculants inorganic me ngā flocculants polymer ka taea te whakapai ake i te pānga coagulation me te whakawhānui ake i te whānuitanga o te tono.
Te inenga o te flocculant
Ina whakamahia te whakapūkara hei rongoā i tētahi wai para, kei reira ngā mea whakapūkara pai rawa atu me te horopeta pai rawa atu, e whakatauhia ana i te nuinga o te wā mā roto i ngā whakamātautau. Tērā pea ka whakaūngia te āhua o te colloid e te nui rawa o te horopeta.
Te raupapatanga horopeta o te flocculant
Ina whakamahia ngā momo wai whakapūkara maha, me whakatau te raupapatanga horopeta tino pai mā roto i ngā whakamātautau. I te nuinga o te wā, ina whakamahia ngātahi ngā wai whakapūkara kore-waro me ngā wai whakapūkara waro, me tāpiri tuatahi ngā wai whakapūkara kore-waro, kātahi ka tāpirihia ngā wai whakapūkara waro.
