Filtration Technology: Txoj Cai Sib Cais Sib Cais Tseem Ceeb
Kev lim dej, zoo li yooj yim ua, ntim cov punch muaj zog.Nws yog kev kos duab ntawm kev cais cov tsis xav tau
los ntawm cov kua (kua lossis roj) los ntawm kev hla nws los ntawm kev thaiv - koj lub lim dej tso siab.Qhov no barrier tso cai rau cov
xav tau kua ntws los ntawm, thaum ntxiab cov khoom tsis xav tau raws li lawv qhov loj me thiab lwm yam khoom.
Xav tias nws yog tus bouncer ntawm ib hmo ntuj, cia tsuas yog cov neeg uas ua tau raws li cov txheej txheem thaum ua kom cov teeb meem tawm.
Kev nkag siab txog lub ntiaj teb zoo sib xws ntawm cov tshuab lim dej yuav tsum muaj ob lub ntsiab lus tseem ceeb:
filtration mechanismsthiablim qhov ntau thiab tsawg.
Tab sis Nquag, Cov no ua hauj lwm ua ke zoo li cov iav hauv lub tshuab roj zoo, ua kom muaj kev sib cais zoo thiab muaj txiaj ntsig zoo.
Grand Jury of Filtration:
* Mechanical filtration:Xav tias sieves thiab daim nyias nyias.Cov khoom loj dua tau snagged ntawm lub lim lub qhov hws, thaum cov me me dhau mus.
* Qhov tob pom:Xav txog ib tug tshawb ntawm fibers nyob rau hauv lub lim.Particles tau daig nyob rau hauv lub labyrinth, tsis muaj peev xwm mus rau txoj kev intricate.
