ʻO ka hoʻokaʻawale ʻana ma waena o ka pae paʻa a me ka pae wai e koi nui ʻia ma waena o nā ʻoihana ākea. Loaʻa ka hoʻokaʻawale ʻana ma o ka decanter centrifuge. Hiki i ka decanter centrifuge ke hoʻokaʻawale i nā ʻāpana paʻa mai ka hoʻokuʻu wai, a i ʻole e hoʻokaʻawale i nā ʻāpana wai like ʻole.

ʻO ka nui o nā hoʻokuʻu ʻia, e like me ka wai ʻino, ka ʻaila ʻaila, ka lepo mining, ka ʻaila pāma, he corrosive a abrasive. No laila ʻO kahi mea ikaika me ka maikaʻi o ka corrosion a me ka ʻaʻahu ʻana e pono ai no nā ʻāpana koʻikoʻi o kahi decanter centrifuge. Ua koho ʻia ʻo Duplex stainless steel 2304 a i ʻole 2205, a me Austenitic stainless steel 304 a i ʻole 316, ma muli o kāna mau waiwai kiʻekiʻe a me ke kumukūʻai kūpono, no nā kīʻaha a me nā ʻōwili o kahi decanter centrifuge.

Ma ke kahua o ka ʻoihana hana pepa, loaʻa ka hopena o ka fiber i nā hopena corrosive i nā mea hana. ʻO ka media corrosion o nā mea hana bleaching ka nui o Cl -, H+ i loko o ka ʻāpana chlorination, a me nā mea hoʻokahe Cl2 a me ClO2. Aia ka corrosion koʻikoʻi ma luna o ka hale kiaʻi chlorination a i ʻole ka mea holoi pulp, ʻaʻole hiki ke hoʻohana ʻia me 316L stainless steel.

ʻO 2101, 2304, a me 2205 duplex stainless steels kūpono loa no kēia mau kūlana hiki ke hoʻoponopono pono i ka pilikia anti-corrosion. Hana ʻia nā rotors a i ʻole impeller o ka mīkini puler me ka duplex stainless steel e ka static casting e hoʻokō i ka hana maikaʻi loa.

I loko o ka ʻāpana hydro-power, ʻo ka impeller, volute a me ka casing pono e pale i ka corrosion a pale aku me ka ikaika a me ka paʻakikī. Hana ʻia kēia mau ʻāpana nui i ke kila kila e ka hoʻolei static.

ʻO nā pahu a me nā paipu, nā ʻaila decanter centrifuges, nā ʻōnaehana hoʻokele paʻa i hoʻohana nui ʻia i ka ʻoihana ʻaila a me nā kinoea. Hoʻohana nui ʻia nā ʻāpana hoʻoheheʻe Centrifugal a me nā ʻāpana hoʻoheheʻe one i kēia mau lako a me nā lako.
