ʻO nā kānana kalapona i hoʻāla ʻia i kekahi manawa i kapa ʻia he mau kānana lanahu he mau ʻāpana liʻiliʻi o ke kalapona, ma ke ʻano granular a poloka paha, i mālama ʻia he porous loa.He 4 grams wale nō o ke kalapona i hoʻāla ʻia ka ʻili e like me ke kahua pôpeku(6400 sqm). ʻO ka ʻili nui e hiki ai i nā kānana kalapona hana ke lilo i mea kūpono loa i ka hoʻopili ʻana (wehe ʻana) i nā mea haumia a me nā mea ʻē aʻe.
Ke kahe ka wai ma o nā kānana kalapona hana, pipili nā kemika i ke kalapona e hopena ai i ka hoʻopuka ʻana o ka wai ʻoi aku ka maʻemaʻe.Aia ka pono ma ke kahe a me ka mahana o ka wai. No laila, pono e hoʻohana ʻia ka hapa nui o nā kānana kalapona liʻiliʻi me ka wai haʻahaʻa a me ka wai anuanu.
Ma waho aʻe o ka ʻili, hiki i nā kānana kalapona hana ke loaʻa nā mana like ʻole e pili ana i ka nui o nā mea haumia a lākou e wehe ai. ʻO kekahi kumu ka maikaʻi o ke kalapona hana me nā pūpū niu i hōʻoia ʻia he maikaʻi loa. Hiki ke hana ʻia ke kalapona hana i ka lāʻau a i ʻole ke lanahu a kūʻai ʻia aku ma ke ʻano he kalapona hana granular a i ʻole nā poloka kalapona.
ʻO kekahi kumu ʻē aʻe ka nui o nā ʻāpana e ʻae ʻia e ke kānana no ka mea hāʻawi kēia i kahi pale lua. ʻAʻohe palena kikoʻī o ke kalapona hoʻāla granular (GAC) no ka mea he porous ka mea. ʻO ke kalapona hoʻāla ma ke ʻano o nā poloka kalapona ma ka ʻaoʻao ʻē aʻe he nui ka pore ma waena o 0.5 a 10 micron. ʻO ka pilikia me nā nui liʻiliʻi loa, ʻo ia ka emi ʻana o ke kahe ʻana o ka wai i ka wā e hakakā ai nā ʻāpana wai e hele. No laila, ʻo nā poloka kalapona maʻamau ma waena o 1-5 micron.
Hiki ke hoʻohana pono ʻia ke kalapona i hoʻāla ʻia i lokoe hōʻemi ana i nā haneli o nā mea e komo pū ana me nā mea haumia a me nā kemika ʻē aʻe mai ka wai paipaEia nō naʻe, ʻo nā haʻawina i ʻōlelo nui ʻia eʻEPAa meNSFe koi i ka wehe pono ʻana ma waena o 60-80 mau kemika, ka hōʻemi pono ʻana o kekahi 30 a me ka hōʻemi kaulike no 22.
He mea nui ka laulā o ka wehe pono ʻana a pili ia i ka maikaʻi o ke kalapona i hoʻāla ʻia a me ke ʻano (GAC vs poloka kalapona). E hōʻoia e koho i kahi kānana e wehe i nā mea haumia e hopohopo nei no kāu wai paipa kūloko.
