Mu ntchito zina, kuumitsa kotentha pang'ono kokhala ndi chinyezi kwapangidwanso kuti kuchepetse chiopsezo chodzitenthetsera kapena moto m'malasha ena.
Kusintha kwa digito, Kudziyendetsa, ndi Kuwongolera Njira Zoyendetsedwa ndi Deta
Kusintha kwa digito ndi njira yayikulu mumakampani opangira mchere, kuphatikizapo malasha. Masensa apaintaneti oyesera kuchuluka kwa phulusa, chinyezi, kukula kwa tinthu, komanso kapangidwe kake kakuchulukirachulukira. Deta yeniyeniyi imaphatikizidwa ndi machitidwe owongolera kuti azilamulira zokha zosintha za njira—monga kuchuluka kwa chakudya, kuchuluka kwa media, kapena mlingo wa reagent.
Kuphatikiza apo, kusanthula deta ndi kuphunzira kwa makina zikuyamba kugwiritsidwa ntchito kulosera khalidwe la malonda, kuzindikira zopinga zomwe zingachitike, ndikuchita kukonza kolosera. Mwachitsanzo, deta yogwedezeka pa ma conveyor motors ndi ma gearboxes imatha kusanthulidwa kuti izindikire zizindikiro zoyambirira za kulephera. Zotsatira zake ndi kuchepa kwa nthawi yogwira ntchito, chitetezo chabwino, komanso kuchepetsa ndalama zogwirira ntchito.
Zatsopano pa Kusamalira Zinthu ndi Kulamulira Fumbi
Kukonza malasha sikungokhudza kulekanitsa ndi kukonza khalidwe, komanso momwe zinthuzo zimagwiritsidwira ntchito mosamala komanso moyenera. Machitidwe amakono otumizira, machubu osinthira okonzedwanso kuti achepetse kutaya madzi, komanso kukhazikitsa machitidwe oletsa fumbi ndizofunikira. Fumbi la malasha si vuto lokha la chilengedwe komanso chiopsezo cha thanzi ndi chitetezo (mwachitsanzo, chifukwa cha kuthekera kwa kuphulika kwa fumbi pansi pa mikhalidwe ina).
Zatsopano zomwe zachitika m'derali zikuphatikizapo kugwiritsa ntchito njira zopangira utsi, zinthu zochepetsera fumbi la mankhwala zomwe siziwononga chilengedwe, malo osungiramo zinthu m'malo osamutsira zinthu, komanso kuyang'anira tinthu tating'onoting'ono mosalekeza. Kampaniyo yayambanso kukonza kapangidwe ka zinthu zosungidwa ndi kubwezeretsanso zinthu kuti ichepetse kusiyanitsa kukula kwa zinthu ndikusunga mtundu wabwino wa zinthu.
Kusamalira Zinyalala za Mgodi ndi Madzi: Kuchokera ku Miyala mpaka Kuzunguliranso kwa Madzi
Kutsuka malasha kumapanga malo osungiramo zinthu ndi kukonza madzi okhala ndi tinthu tating'onoting'ono. Kusamalira zinyalalazi ndi nkhani yofunika kwambiri, makamaka pankhani yokhazikika kwa malo osungiramo zinthu komanso kutsatira malamulo okhudza chilengedwe. Chifukwa chake, zatsopano cholinga chake ndi kuchepetsa kuchuluka kwa zinyalala, kuwonjezera kuchuluka kwa madzi obwezeretsanso, komanso kukonza bwino madzi otayira.
Ukadaulo wamakono wothira madzi pogwiritsa ntchito njira yolondola yowongolera flocculant ukhoza kuwonjezera kubweza madzi. Makina osefera ndi okhuthala a paste amathandiza kusintha malo otayira madzi kukhala chinthu chokhazikika komanso chosavuta kugwiritsa ntchito. Njira ya "zero liquid discharge", kapena closed water circulation, ikugwiritsidwanso ntchito m'malo ena, kutengera momwe zinthu zilili m'deralo komanso zachuma.
Kukweza Malasha ndi Kuonjezera Mtengo Wowonjezera
Kupatula kutsuka, pali njira zatsopano zowongolera khalidwe la malasha, makamaka malasha otsika mtengo, omwe nthawi zambiri amakhala ndi chinyezi chambiri.
