Anionic Polyacrylamide (APAM) - Flocculant no ka mālama ʻana i ka wai
Nā hiʻohiʻona koʻikoʻi
• Hoʻoheheʻe wikiwiki, koena haʻahaʻa: ʻO ka manawa hoʻoheheʻe o ka pauka PAM ≤ 60 mau minuke (ma ka mahana o ka lumi), ma hope o ka hoʻoheheʻe ʻana, nui nā flocs a noho koke (ʻo ka wikiwiki o ka hoʻonohonoho ʻana he 25%-40% wikiwiki ma mua o nā huahana maʻamau), a hana maikaʻi ia ke hoʻohana ʻia me ka PAC. ʻO ka mea wai ʻole ≤ 0.5%.

Wahi Noi
• ʻŌpala wai o ke kūlanakauhale: ʻO ka flocculation i loko o ka pahu sedimentation mua a me ka pahu sedimentation lua o nā hale hana hoʻomaʻemaʻe wai ʻino kūloko o ke kūlanakauhale e hōʻemi i ka SS (nā mea paʻa i hoʻokuʻu ʻia) i lalo o 10mg/L;
• Wai hoʻoheheʻe pepa: ka wehe ʻana i ka wai ʻeleʻele pulping, ka hoʻōla ʻana o ka wai keʻokeʻo (ua piʻi ka nui o ka hōʻiliʻili ʻana o ka fiber ma 15%-20%);
• Wai ʻino holoi lanahu/mine: Ka Hoʻomālamalama ʻana o ka Wai Slurry Lanahu (Ua piʻi ka nui o ka hōʻiliʻili ʻana o ka Flotation Clean Coal ma 8%-12%), Flocculation a me Sedimentation ma ka Tailings Pond
• Nā Mea Hana Hale Wai ʻŌpala: Hoʻopau ka wai hoʻoheheʻe hana mai nā hale hana sima a me nā hale hana seramika i nā mea paʻa i hoʻokuʻu ʻia (ua hoʻemi ʻia ka turbidity mai 2000 NTU a i 50 NTU).
Ka Hoʻopili ʻana a me ka Mālama ʻana
• Nā Kūlana Mālama: E mālama i kahi maloʻo a me kahi anu (mahana ≤ 35°C), e pale i ka lā pololei; ʻo ke ola papa o ka mea paʻa he 2 mau makahiki (ʻaʻole i wehe ʻia).
