Si loo dhajiyo ama loo isticmaalo bullaacadda bullaacadda ka dib daaweynta, kiimikooyin kala duwan oo kala duwan ayaa loo baahan yahay in loo isticmaalo habka daaweynta bullaacadda bullaacadda. Maanta,Pam (polyacrylamide) alaab-qeybiyeyaashaayaa kuu sheegi doona wax ku saabsan flocasulas:
Dicculant: Mararka qaarkood sidoo kale waxaa sidoo kale loo yaqaan 'Coaulant', waxaa loo isticmaali karaa in lagu xoojiyo kala-goynta dareeraha ah ee isku-dhafka ah, waxaana loo isticmaali karaa haanta xariga hoose, haanta deganaanshaha, taangiga deganaanshaha, daaweynta jaamacadda ama daaweynta kale ee nidaamka.
Flosculas waxaa loo isticmaalaa in lagu xoojiyo kala goynta kala duwan ee dareeraha ee duurka daaweynta bullaacadda. Waxaa loo isticmaali karaa in lagu xoojiyo sicirka aasaasiga ah ee bullaacadda bullaacadda ah iyo dareeraha sare ee dib-u-goynta ka dib marka sidoo kale loo istcimaalo daaweyn culus ama daaweyn sare oo bullaacadeed. Markii loo isticmaalo xaalada ka hor kaadida-goynta xad-dhaafka ah, flocasjuults iyo coluladaha waxay noqdaan qaboojiyeyaal jilicsan ama wakiilo fuuq-baxa.
Markaad isticmaaleyso flocasculadaha dhaqameed, habka lagu daro aaladaha coaulant waxaa loo isticmaali karaa in lagu wanaajiyo saameynta floccation. Tusaale ahaan, adoo adeegsanaya acid siliclic oo firfircoon oo ah gargaar isku dhac ah oo loogu talagalay flochulates-ka gudaha ah sida sulfate froring ah sida sulfate iyo aluminium sulfate iyo ku darista isku xigta si taxaddar leh loo gaari karo. Sidaa darteed, shuruudaha beenta, The Plymy polymer polymculant IPM waxaa dhab ahaan loo diyaariyey iyada oo la isku darey gargaarka coaulan iyo ka dibna lagu daro si ay u fududeeyaan qalliinka isticmaalaha.
Daaweynta isku-dhafka ah waxaa badanaa lagu hayaa hordhaca kala goynta dareeraha ah, oo ay weheliso xarunta kala go'ida, waxay yareyn kartaa cabirka walxaha ka jira ee ah 1NM illaa 100Ml, waxaana loo isticmaali karaa is-gaadhsiinta howlaha daaweynta bullaacadda bullaacadda. Daaweynta, daaweynta horumarsan, waxaa sidoo kale loo isticmaali karaa daaweynta qashinka haraaga ah. Daaweynta isku-darka ayaa sidoo kale si wax ku ool ah uga saari kara sheybaarka loo yaqaan 'patutenics' Heerka ka saarida fosfooraska ee ku jira bullaacadda ayaa ka sarreyn kara 90% marka si khaldan loo isticmaalo si loo daweeyo fosfooraska. ~ 95%, waa habka ugu jaban uguna hufan ee ka saarida fosfooraska.
Inta lagu gudajiro daaweynta bullaacadda bullaacadda, wakiiladaha kale ayaa la isticmaali doonaa. Maanta, TheSoosaaraha Pamsoo saaray mid ka mid ah. Wali miyaad fahantay? U fiirso Yungag oo ka jawaab aqoonno daaweyn bullaacad dheeri ah!
