ʻO ka hana hou ʻO ka mīkini kānana kāʻei piha piha pono no ka ʻeli ʻana, ka mālama ʻana i ka lepo

ʻO ka paʻi kānana kāʻei he ʻano paʻa, ke ʻano moʻolelo, ka hana maʻalahi a me ka hoʻokele, ka mana hana nui, ka haʻahaʻa haʻahaʻa o ka keke kānana a me ka hopena maikaʻi. Ke hoʻohālikelike ʻia me nā ʻano mea like like, loaʻa iā ia nā hiʻohiʻona penei:

1. ʻO ka ʻāpana hoʻoheheʻe umekaumaha mua i nclined, kahi e hoʻonui ai i ka sludge a hiki i 1700mm mai ka honua, hoʻonui i ke kiʻekiʻe o ka sludge i ka ʻāpana dewatering gravity, a hoʻomaikaʻi i ka hiki ke hoʻohaʻahaʻa i ka gravity.

2. He lōʻihi ka pauku hoʻoheheʻe umekaumaha, a ʻoi aku ka nui o ka pauku hoʻoheheʻe ʻumekaumaha mua a me ka lua ma mua o 5m, ʻo ia ka mea e hoʻoheheʻe ʻia ai ka sludge a nalowale kona wai ma mua o ke kaomi ʻana. I ka manawa like, ua lako pū ka ʻāpana dehydration gravity me nā mīkini kūikawā e like me ka hoʻohuli ʻana, hiki ke hana i ka sludge filter cake e loaʻa ka liʻiliʻi o ka wai ma o nā hana o ka wedge-shaped a me S-shaped press. 3. Hoʻohana ʻia ka pahu wai hoʻoheheʻe wai mua "t", kahi e hoʻokuʻu koke ai ka wai nui ma hope o ke kaomi ʻana, pēlā e hoʻomaikaʻi ai i ka hopena dewatering.
