PolyAluminium Chloride (PAC) · Mana Wai
Nā Hiʻohiʻona Koʻikoʻi
• Pane wikiwiki: He kiʻekiʻe ka hana o nā molekala wai, a ʻo ka wikiwiki o ka flocculation he 20% wikiwiki ma mua o ka mana paʻa, e kūpono loa ana no nā hale mālama wai liʻiliʻi a i ʻole nā kūlana pilikia;
• Ka Haʻahaʻa o ka ʻAʻai: Ka hiki ke hoʻololi i ka pH ākea (4-10), me ka haʻahaʻa o ka palaho i nā paipu/lako ma mua o nā paʻakai alumini kiʻekiʻe.

Ka Hoʻopili ʻana a me ka Mālama ʻana
• Ka mālama ʻana: E mālama i kahi wahi anu a maikaʻi ka ea, e pale i ka lā pololei, a ʻo ke ola papa he 6 mahina (paʻa ʻia).
Nā Hiʻohiʻona Pili
Ua hoʻohana nui ʻia kā mākou PAC i nā hiʻohiʻona mālama wai ʻoihana a me ke kūlanakauhale ma ka honua holoʻokoʻa, me nā hihia maʻamau e like me:
• Ka hoʻomaʻemaʻe ʻana i ka wai inu: Ka wehe ʻana i ka hao a me ka manganese mai ka wai honua, ka wehe ʻana i ka turbidity mai ka wai o luna, ka hoʻokō ʻana i nā kūlana wai inu honua;
• ʻŌpala wai o ke kūlanakauhale: ʻO ka hoʻokahe ʻana o ka coagulation, ka hoʻohemo ʻana i ka sludge, BOD (biochemical oxygen cointen) i loko o nā hale hana hoʻomaʻemaʻe wai kūloko o ke kūlanakauhale;
• Wai hoʻoheheʻe ʻoihana: Ka mālama ʻana i ka wai ʻeleʻele hana pepa (delignification, hoʻemi ʻana i ke COD), decolorization o ka wai hoʻoheheʻe ʻia o ka paʻi a me ka hoʻoluʻu ʻana (ka wehe ʻana i nā dyes reactive, nā dyes sulfur), ka wehe ʻana i nā metala kaumaha mai ka wai hoʻoheheʻe electroplating (Cr⁶⁺, Cu²⁺), a me ka wehe ʻana i ka phosphorus mai ka wai hoʻoheheʻe kemika;
• Nā hiʻohiʻona ʻē aʻe: Ka hoʻomaʻemaʻe ʻana i ka wai paheʻe lanahu i loko o nā hale hana hoʻomākaukau lanahu, ka wehe ʻana i ka ʻaila mai ka wai hoʻokomo hou ʻana o ke kahua ʻaila, a me ka hana hou ʻana i ka wai hoʻoneoneo ʻoki pōhaku.
