Flocculation - aluminum sulphate vs poly aluminim chloride

ʻO ka flocculation ke kaʻina hana e nā mea i hoʻopiʻiʻia i hoʻopiʻiʻia i hoʻopiʻiʻia i kahi i hōʻikeʻia ma kahi paʻa paʻa i loko o ka wai i makeʻia ai ka wai. Loaʻaʻia kēia ma ka hoʻohuiʻana i kahi coagulant kūpono kūpono. ʻO ka uku kūpono i loko o ka coagulant neutralizes i nā mea maikaʻiʻole i hōʻikeʻia i loko o ka wai (ʻo ia ka stepbilizes ia). Ke hele nei nā'āpana i nā'āpana a iʻole ka hanaʻana, ua hele ka hana flogculation. Hoʻopiliʻia nā mea i hoʻopiliʻia i nā'āpana nui aʻoi aku ka nui o ka nui a me ka nui o ka nui e noho ai e ka sediment a he nui paha i ka nui o ka ea a me ka papahele.

I kēia lā e lawe aku mākou i kahi kokoke i nā wahi flocculation o nā flocculationʻelua o nā flocculantsʻelua: poly aluminum culfate.

Ua sulnunum a Alminum sulfate:ʻO Aluminum Sulfate he Acidic ma keʻano. ʻO ke kumu hana hana o keʻano aluminum sulfate penei: E hana anaʻo Aluminim i ka hana aluminute, al (0h) 3. Loaʻa i nā hydroxides aluminumides e loaʻa i ka pae phone . ^. Pono e lawa ka alkalinity i loko o ka wai i ka wā o ke kaʻina flogculation e hōʻoia i ka pauʻana o ka hydroxide insolixide a paʻaʻia. Hoʻokuʻu i nā mea kala a me nā collidal i nā mea hoʻohui ma o ka hui pūʻana o ka adsorption a me ka hydrolysis ma / i loko o nā hydropedes i loko / i loko o nā hydroxides. No laila,ʻo ka puka makani o ka lawelaweʻana o ka alumini sulfate he 5.8-8.5.5

PoLauumum(PAC) kekahi o nā mea maikaʻi maikaʻi loa e hoʻohana i nā kemika e hoʻohana ai i kēia lā. Ua hoʻohana nuiʻia ia i ka inu wai a me ka mālamaʻana i ka hana no ka nui o kona coagulation kiʻekiʻe a me ka nui o nā noi o ka bh a me ka nui o nā noi i hoʻohālikelikeʻia i nā mea hana'ē aʻe. Loaʻa nā PAF ma nā helu likeʻole me nā mea hana a Allumina i ka nui o 28% a 30%. ʻAʻoleʻo ia keʻano o kaʻikeʻanaʻo Alumina i ke kohoʻana i ka wā e koho ai i kahi o nā papa o Pac e hoʻohana.

Hiki ke noʻonoʻoʻiaʻo PC e like me kahi coagulant ma mua. ʻO nā clusters alumini mua loaʻo Aluminim i loaʻa i ka hōʻai'ē maikaʻi loa, kahi e hana aiʻo Pac ma mua o ka hoʻonuiʻana i nā mea i hoʻopiʻiʻia i loko o ka wai.

Loaʻa i nā Pa Pa Pac

1. Hana ia i nā mea haʻahaʻa haʻahaʻa haʻahaʻa. Me he rula o ka thumb, ke kumu o ka pac dose e pili ana i hoʻokahi hapakolu o ka dose i koiʻia no ka alum.

2. Waiho ia i ka liʻiliʻi o ka alumini i ka wai i mālamaʻia

4. Hana ia ma luna o kahi ākea ph laulā

Nui nā kumu o nā Flocilesnts, a hoʻopuka wale kēiaʻatikala iʻeluaʻelua o lākou. Ke kohoʻana i kahi coagulant, ponoʻoe e noʻonoʻo i ka maikaʻi o ka wai āu e hoʻomaʻamaʻa ai a me kāu kālā kālā pono'ī. Manaʻo wau he loaʻa maikaʻi o kāu hana wai maikaʻi. Me he mea lā e mālama ai ka wai i ka mea kūʻai aku me nā makahiki 28 o kaʻike. Hauʻoli wau e hoʻoponopono i kāu mau pilikia a pau (e pili ana i ka wai hana wai wai).
