ʻO ke ʻano kino a me ka micro o ka mea biofilter pōhaku pele i hōʻike ʻia e ka ʻili ʻino a me ka micropore, kahi mea kūpono loa no ka ulu ʻana a me ka hana hou ʻana o nā microorganism ma kona ʻili e hana i ka biofilm. ʻAʻole hiki i ka mea kānana pōhaku pele ke mālama wale i ka wai hoʻoneoneo kūlanakauhale, akā, i ka wai hoʻoneoneo biochemical organic industrial, ka hoʻokahe wai home, ka wai kumu haumia micro, a pēlā aku. Hiki iā ia ke pani i ke one quartz, carbon activated, anthracite ma ke ʻano he media kānana i ka mālama ʻana i ka wai. I ka manawa like, hiki iā ia ke hana i ka mālama holomua no ka wai huelo ma hope o ke kaʻina hana lua o ka hale hana mālama wai ʻino, a hiki i ka wai i mālama ʻia ke hiki i ke kūlana wai hoʻohana hou. Hiki ke hoʻohana ʻia no ka hoʻohana hou ʻana i ka wai i hoʻihoʻi ʻia.

Eia ke ʻano kemika o ka mea biofilter pōhaku pele

1. Paʻa kemika microbial: ʻo ka mea biofilter pōhaku pele he kūpaʻa i ka pala, inert, a ʻaʻole ia e komo i ka hopena biochemical o ka biofilm i ke kaiapuni.

2. Uila ʻili a me ka hydrophilicity: he uku maikaʻi ka ʻili o ka biofilter pōhaku pele, kahi e kūpono ai i ka ulu ʻana o nā microorganism. Loaʻa iā ia ka hydrophilicity ikaika, ka nui o ka biofilm i hoʻopili ʻia a me ka wikiwiki.

3. Ma ke ʻano he mea lawe o ka biofilm, ʻaʻohe hopena ʻino a pale aku o ka biofilter pōhaku pele i ka microorganism i hoʻopaʻa ʻia, a ua hōʻoia ʻia ʻaʻole ia e hoʻopilikia i ka hana o ka microorganism.

ʻO ka hana hydraulic o ka biofilter pōhaku pele penei

1. Porosity: ʻo ka awelika o ka porosity i loko a i waho ma kahi o 40%, a he liʻiliʻi ke kū'ē ʻana i ka wai. I ka manawa like, i hoʻohālikelike ʻia me ke ʻano like o nā mea kānana, ʻoi aku ka liʻiliʻi o ka nui o nā mea kānana e pono ai, hiki ke hoʻokō i ka pahuhopu kānana i manaʻo ʻia.

2. ʻĀpana ʻili kikoʻī: ʻāpana ʻili kikoʻī nui, porosity kiʻekiʻe a me ka inert, kahi mea e kūpono ai i ka hoʻopili ʻana a me ka ulu ʻana o nā microorganism, mālama i ka biomass microbial hou aʻe, a hoʻomaʻamaʻa i ke kaʻina hana hoʻoili nui o ka oxygen, nā meaʻai a me nā ʻōpala i hana ʻia i ke kaʻina hana o ka metabolism microbial.

3. Ke ʻano o ka mea kānana a me ke ʻano o ke kahe ʻana o ka wai: no ka mea, ʻaʻole i kiko ka mea kānana olaola pōhaku pele, a ʻoi aku ka nui o ke anawaena o ka pore ma mua o ka ceramsite, he liʻiliʻi kona pale ʻana i ke kahe ʻana o ka wai a mālama i ka hoʻohana ʻana i ka ikehu.
