Kugwiritsa ntchito PAC pamakampani opanga mapepala

Polyaluminium Chloride (PAC) ndi mankhwala ofunikira pamakampani opanga mapepala, omwe amagwira ntchito yofunika kwambiri pamagawo osiyanasiyana opanga mapepala. PAC ndi coagulant yomwe imagwiritsidwa ntchito kupititsa patsogolo kusungidwa kwa tinthu tating'onoting'ono, zodzaza, ndi ulusi, potero kumapangitsa kuti pakhale bwino komanso kupanga mapepala.

Coagulation ndi Flocculation

Ntchito yayikulu ya PAC pakupanga mapepala ndikuphatikiza kwake komanso kusuntha kwake. Pakupanga mapepala, madzi amasakanikirana ndi ulusi wa cellulose kuti apange slurry. slurry iyi imakhala ndi tinthu tating'onoting'ono tomwe timasungunuka komanso zinthu zosungunuka zomwe zimafunika kuchotsedwa kuti zipange mapepala apamwamba kwambiri. PAC, pamene anawonjezera ku slurry, neutralizes zoipa mlandu pa inaimitsidwa particles, kuwachititsa clump pamodzi lalikulu aggregates kapena flocs. Njirayi imathandiza kwambiri kuchotsa tinthu tating'onoting'ono timeneti timatulutsa madzi, zomwe zimapangitsa kuti madzi azikhala omveka bwino komanso kusunga bwino fiber.

Kusungirako Bwino ndi Kukhetsa

Kusunga ulusi ndi zodzaza ndi zofunika kwambiri pakupanga mapepala chifukwa kumakhudza mwachindunji kulimba kwa pepala, mawonekedwe ake, komanso mtundu wake wonse. PAC imathandizira kusungidwa kwa zinthu izi popanga magulu akuluakulu omwe amatha kusungidwa mosavuta pawaya wamakina amapepala. Izi sizimangowonjezera mphamvu ndi mtundu wa pepala komanso zimachepetsa kutayika kwa zinthu zopangira, zomwe zimapangitsa kuti ndalama zisungidwe. Kuonjezera apo, madzi oyenda bwino omwe amayendetsedwa ndi PAC amachepetsa madzi omwe ali mu pepala, motero amachepetsa mphamvu yowumitsa ndi kupititsa patsogolo ntchito yonse yopanga mapepala.

Kupititsa patsogolo Ubwino wa Mapepala

Kugwiritsa ntchito PAC pakupanga mapepala kumathandizira kwambiri kuwongolera kwabwino kwa mapepala. Pokulitsa kusungidwa kwa chindapusa ndi zodzaza, PAC imathandizira kupanga mapepala okhala ndi mawonekedwe abwino, ofanana, komanso mawonekedwe apamwamba. Izi zimapangitsa kusindikizidwa bwino, kusalala, ndi maonekedwe onse a pepala, zomwe zimapangitsa kuti zikhale zoyenera kusindikiza ndi kulongedza kwapamwamba kwambiri.

Kuchepetsa kwa BOD ndi COD pakupanga Papermaking Waste Water Treatment

Biochemical Oxygen Demand (BOD) ndi Chemical Oxygen Demand (COD) ndi miyeso ya kuchuluka kwa zinthu zamoyo zomwe zimapezeka m'madzi onyansa omwe amapangidwa ndi kupanga mapepala. Kuchuluka kwa BOD ndi COD kumawonetsa kuchuluka kwa kuipitsa, komwe kumatha kuwononga chilengedwe. PAC imachepetsa bwino milingo ya BOD ndi COD polumikizana ndikuchotsa zonyansa m'madzi onyansa. Izi sizimangothandiza kukwaniritsa malamulo a chilengedwe komanso zimachepetsanso mtengo wa mankhwala okhudzana ndi kayendetsedwe ka madzi onyansa.

Mwachidule, polyaluminium chloride ndiyowonjezera yofunika kwambiri pantchito yopanga mapepala, yopereka maubwino angapo omwe amapangitsa kuti ntchito yopangira mapepala ikhale yabwino komanso mtundu wa chinthu chomaliza. Maudindo ake pakuphatikizana ndi kusefukira, kusungika bwino komanso kukhetsa madzi, kuchepetsa BOD ndi COD, komanso kuwongolera bwino kwamapepala kumapangitsa kuti ikhale yofunika kwambiri pakupanga mapepala amakono.
