1. Filter sabkood Filtarka saxal qaraxadka waxaa lagu yimid dadkii oo dhammaan ee midhooyinka ah, koloidyo iyo xaaladaha mekanikalka ah ee granular, markii uu sand filter ku jirin, wuxuu ka mid ah "proseska fisika-kiimiyadi". Markii maalmahay hore ee carruurta ah oo ku jirin malaabada ah, wuxuu soo diray carruurta iyo suspoysiontii koloidyooda oo ka mid ah carruurta, si carruurtii ugu dambeeyo. Modeedka filtarada mekanikal ayaa manual control ah. Kuna fiiri karo, markii uu multi-medium filter ku jirin, wuxuu ka mid ah proseska badan ah iyo loogu talagalay in la sameyn doontaa carruurtii ugu dambeeya iyo carruurinta eeg. 2. Filtarka karbunka faahfaahi Kuna carruurtida carruurka ah waxaa jiro carruurta dhexe, carruurta dhulka ama carruurta faafin, midkii carruurka ah carruurka kale oo ku jira carruurka la'anta ah ayaa ugu yar reer. Carruurka composite reverse osmosis ee dhalinyarada ah ayaa ka mid ah maxkamadda carruurka la'anta ah, oo lacagga ayaa doonaysaa kuma helaynta 0.1mg/L. Keliya, filterka carbo waxaa lagu sameeyay in la'aanka carruurka ah carruurka la'anta ah ka soo galita, sababtoo waxaa jirto lacag iyo magansee ee carruurka ah ayaa ugu yar reer, oo Longoria index ayaa si toos ah ah. Rateynta desalination ee reverse osmosis ayaa ah 97%, sidaas daraaddeed sidee carruurka ah ayaa u leeyahay lacag carruur, magansee carruur, iyo magansee sulfat ee dhalinyarada ah oo ku jira lacagga carruurka ah carruurka ah carruurka ah carruurka ah. Sidaas daraaddeed, carbon filter waxaa la isaga sameeyay in deviceka reverse osmosis ugu yar reer ka soo jeedo, safe ah, stable ah, iyo reliable ah. 3. Filter badbaadaha ion Resin cation wuxuu ka soo dirirayaa si carruurka carruursanaha, waxa uu sheegaya sidaas oo carruursanaha loo qeyb karo. Carruursanaha waa caqligga dhexeeya ah ee Ca2 +, Mg2 + jidad aanuun, haddii carruursanaha ku sameeyo hard marka la xiriira resin layer, carruursanaha Ca2 +, Mg2+ waa jidadka resin ayuu ugu yimid adsorption, iyo dadkii kale oo dhammaystiran Na + jidadka carruurka ah oo leh softener ka soo jeeda in lagu sameyn doontaa carruursanaha hard ions.
