Ke Kūlana Huahana

He huahana hui polymer inorganic kēia huahana, i hoʻokumu ʻia ma ka polyaluminum chloride a ua hui pū ʻia me ka hao polymeric, e hoʻonui ana i ke ʻano molekala, e hoʻoikaika ana i ka electro-neutralization, e hoʻopili ana i ka adsorption, a me ka hana sedimentation, a he mea kūpono ia no ka mālama ʻana i ka wai kumu me ka haumia organik koʻikoʻi a me ka wai kumu me ka mahana haʻahaʻa a me ka turbidity haʻahaʻa a i ʻole ka mahana haʻahaʻa a me ka turbidity kiʻekiʻe.

Hana Koʻikoʻi

Hoʻohui hohonu ʻo PAFC i nā pono pālua o nā iona alumini (Al³⁺) a me nā iona hao (Fe³⁺), e hoʻoponopono ana i nā palena o nā flocculants hoʻokahi, a ʻo kāna hana nui penei:

1. Hoʻonui ka synergy alumini-hao i ka pono o ka flocculation ma mua o 30%.

• ʻO ka hoʻopili ʻana i ka uku pālua: Hoʻopili ʻo Al³⁺ i nā colloids i hoʻopiʻi maikaʻi ʻole ʻia (e like me ka lepo a me ka waikawa humic) ma o ka "neutralization uila"; Hopu ʻo Fe³⁺ i nā ʻāpana liʻiliʻi (e like me nā mea organik a me nā microorganisms) ma o ka "capture net", e hana ana i nā flocs i ʻoi aku ka paʻa a noho wikiwiki (ka wikiwiki o ka noho ʻana ≥ 25 m/h).

• Ka Hoʻololi ʻana i ka pH ākea: ʻO ka pae pH kūpono he 4-10 (kūpono 6-9), kūpaʻa i ka turbidity kiʻekiʻe (≤10000 NTU), ka paʻakai kiʻekiʻe (e laʻa, ka mālama mua ʻana i ka desalination wai kai), a me ke ʻano wai o nā mea olaola kiʻekiʻe (e laʻa, ka paʻi ʻana a me ka hoʻoluʻu ʻana/ka wai hoʻoheheʻe pepa), e uhi ana ma luna o 90% o nā hiʻohiʻona mālama wai honua.

Nā Hiʻohiʻona Pili

ʻO PAFC, me kona mau ʻano "ā puni", hoʻohana nui ʻia i nā kūlana mālama wai kūloko, ʻoihana, a me nā kūlana mālama wai kūikawā o ka honua:
• ʻŌpala wai o ke kūlanakauhale: E hōʻemi i ka SS, e wehe i kahi ʻāpana o COD
• Ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai hoʻokahe: decolorization, wehe ʻana i nā mea olaola
• Ka hoʻopili uila/wai ʻino kemika: Ka wehe ʻana i nā metala kaumaha (Cr⁶⁺, Cu²⁺) a me nā mea hoʻopili
• Wai hoʻoheheʻe pepa/wai hoʻoheheʻe ʻeli: Hoʻōla wai keʻokeʻo, hoʻomālamalama wai slurry lanahu
• Ka wai hoʻoheheʻe meaʻai: Ka wehe ʻana i nā mea paʻa starch/protein i hoʻokuʻu ʻia

Ka Hoʻopili ʻana a me ka Mālama ʻana

1. Ka hoʻopili ʻana
•ʻAno wai (PAFC): Pahu palaki 200L, ʻeke ʻeke IBC 1000L, ʻeke wai;
•ʻAno Paʻa: ʻeke ulana 25kg i hoʻopaʻa ʻia me ka ʻeke palakiko (kaumaha ʻupena 25kg), ʻeke jumbo 1-tona (kaumaha ʻupena 1000kg, hiki ke paʻi ʻia me ka logo o ka mea kūʻai aku/lepili Pelekane);

2. Ka Waihona
•ʻAno wai: E mālama pono i kahi i hoʻopaʻa ʻia ma kahi anuanu a me ka ea maikaʻi (mahana ≤ 30°C), e pale i ka lā pololei, a e mālama ʻia mai nā kumu ahi;
•ʻAno paʻa: E mālama i loko o kahi hale kūʻai maloʻo (haumākū ≤ 60%), e pale aku i ka makū a me ka hōʻino ʻia, a ʻaʻole e hoʻomoe ma mua o 2 papa kiʻekiʻe;
•Ka lōʻihi o ka mālama ʻana: 12 mahina no ke ʻano wai (paʻa), 24 mahina no ke ʻano paʻa (wehe ʻole ʻia).
