Nā lako hana hoʻomaʻemaʻe wai ʻino home me ka mana ʻole (pahu kaiaola)

Hoʻokomo mua ka wai ʻeleʻele i loko o ka pahu septic mua no ka mālama mua ʻana, kahi e pale ʻia ai ka scum a me ka sediment, a komo ka supernatant i ka ʻāpana mālama biochemical o nā lako. Hilinaʻi ia i nā microorganism i loko o ka wai a me ka mea hoʻopihapiha moena neʻe ma hope o ke kau ʻia ʻana o ka membrane no ka mālama ʻana, hydrolysis a me ka acidification e hoʻohaʻahaʻa i nā mea organik, hoʻemi i ka COD, a hana i ka ammonification. Ma hope o ka mālama biochemical, kahe ka wai ʻino i loko o ka ʻāpana mālama kino o ka backend. ʻO nā mea kānana hana i koho ʻia he adsorption i kuhikuhi ʻia o ka ammonia nitrogen, interception o nā mea paʻa i hoʻokuʻu ʻia, pepehi ʻana iā Escherichia coli, a me nā mea kākoʻo, hiki ke hōʻoia i ka hōʻemi pono ʻana o COD a me ka ammonia nitrogen i loko o ka effluent. Ma ke kumu o ka hoʻokō ʻana i nā kūlana irrigation kumu, hiki ke hoʻokō i nā koi kiʻekiʻe. Hiki ke hoʻolako ʻia ka backend me kahi pahu wai maʻemaʻe hou e hōʻiliʻili a mālama i ka wai huelo, e hoʻokō ana i nā koi no ka hoʻohana ʻana i nā kumuwaiwai ma nā wahi kuaʻāina.
