Paʻi Kāʻei ʻOihana no ka hoʻomaʻemaʻe wai ʻana o ka lepo

ʻO ke kāʻei kāʻei (kahi i ʻike ʻia ʻo ke kāʻei kānana kāʻei a i ʻole ka kānana kāʻei) he mīkini hoʻokaʻawale wai ikaika. Me kona ʻano kāʻei kānana kāʻei S-like, hoʻonui mālie ʻo ia i ke kaomi ma luna o ka sludge no ka dewatering ʻoi aku ka maikaʻi. He kūpono kēia mea hana no nā ʻano mea like ʻole, me nā mea hydrophilic organik a me nā mea hydrophobic inorganic, ʻoi aku hoʻi i nā ʻoihana kemika, mining, a me nā ʻoihana hoʻōla wai.
Loaʻa ka kānana ma ka hānai ʻana i ka lepo a i ʻole ka slurry ma o kahi ʻōnaehana wili ma waena o nā kāʻei kānana permeable. ʻO ka hopena, ua hoʻokaʻawale ʻia ka wai mai nā mea paʻa, e hana ana i kahi keke kānana maloʻo. Hoʻonui ka ʻāpana hoʻohaʻahaʻa gravity lōʻihi i ke kaʻina hoʻokaʻawale, e hana maikaʻi loa ia no nā ʻano sludge like ʻole.
