Hana ka mea hoʻomānoanoa pahu me ke kaʻina hana hoʻomānoanoa pahu rotary e loaʻa ai kahi hopena lapaʻau paʻa kiʻekiʻe.
Ua mālama ʻia nā kumukūʻai o ka ʻāina, ke kūkulu ʻana a me ka hana ʻana no ka mea ʻoi aku ka liʻiliʻi o ka wahi papahele o kēia mīkini me kona ʻano maʻalahi, nā koi flocculent liʻiliʻi a me ka hana piha piha.

ʻO ka hopena, ua mānoanoa ka slurry. Ua hoʻomaikaʻi ʻia ka hiki ke hana o kā mākou mea hoʻomānoanoa sludge drum rotary, a ua pōkole ka manawa hana. Hiki i ka sludge i hoʻokaʻawale ʻia ke hōʻemi nui i ka ukana o ke kāʻei no ka hoʻokomo ʻana i ka wai. I kēia manawa, ua kūkulu paʻa ʻia ka hui sludge. ʻAʻohe hanana sheet-dish a i ʻole side-overflow e hana ʻia. A laila, hoʻonui ʻia ka pono o ka dehydration, a ua hoʻohaʻahaʻa ʻia ka nui o ka wai. Ma hope o ka hoʻokaʻawale ʻana, ʻokoʻa ka nui o nā mea paʻa o ka wai manuahi mai 0.5‰ a i 1‰, kahi e pili pono ana i ka dosage a me nā ʻano o ka polymer.

Hiki i ka mīkini hoʻomānoanoa pahu wili hapa-centrifugal ke kānana i ka wai manuahi ma o ka ikaika o waho. Loaʻa iā ia nā koi kiʻekiʻe no ka polymer a me ka ikaika hoʻopaʻa o ka sludge. I ka hoʻohālikelike ʻana me ka mīkini hoʻomānoanoa kāʻei, hiki i kā mākou mīkini hoʻomānoanoa sludge pahu wili ke hāʻawi i ka sludge mānoanoa me ka haʻahaʻa o ka wai. ʻOi aku ka maikaʻi o ka sludge me kona ʻike wai ma luna o 1.5%.
