PAM ee daaweynta biyaha
Hordhac
PAM (Polyacrylamide) waa nooc polymer ah oo loo isticmaalo codsiyo kala duwan, oo ay ku jiraan daaweynta biyaha. Polyacrylamide waxaa sida caadiga ah loo isticmaalaa sida flocculant ee hababka daaweynta biyaha si loo hagaajiyo dejinta walxaha laalan, taasoo sahlaysa in la kala saaro adkaha biyaha.
Polyacrylamide (PAM) waa iskudhis polymer ah oo si weyn loogu isticmaalo goobta daaweynta biyaha. Waxay ku timaadaa noocyo badan oo kala duwan, oo ay ku jiraan nonionic, cationic, iyo anionic.

Codsiyada
Floculant:Polyacrylamide waxaa inta badan loo isticmaalaa sida flocculant ee daaweynta biyaha si meesha looga saaro adkaha hakadka ku jira, walxaha qayb ka ah iyo kolloidyada oo ay isku ururiyaan qaybo waaweyn si loo fududeeyo soo saarista xiga ama sifaynta. Isku-duubnidaani waxay gacan ka geysataa hagaajinta caddaynta biyaha iyo hufnaanta.
Kordhiye roobab:Polyacrylamide waxay samayn kartaa dhismo leh ion bir ah si kor loogu qaado saamaynta dabaylaha. Marka la daaweynayo biyaha wasakhda ah ee ay ku jiraan ion birta, isticmaalka polyacrylamide wuxuu wanaajin karaa saameynta roobabka waxayna yareyn kartaa waxa ku jira ions birta ee biyaha wasakhda ah.
Antiscalant:Habka daaweynta biyaha, polyacrylamide sidoo kale waxaa loo isticmaali karaa miisaan ka hortag ah si looga hortago in la isku xoqo dusha tuubooyinka iyo qalabka. Waxay wanaajisaa dheelitirka ion ee biyaha, waxay joojisaa kaydinta walxaha kala diri ee biyaha, waxayna yaraynaysaa samaynta miisaanka.
Horumarinta tayada biyaha:Polyacrylamide sidoo kale waxaa loo isticmaali karaa si loo hagaajiyo tayada biyaha xaaladaha qaarkood, sida kordhinta heerka sedimentation ee adkaha la hakiyey ee biyaha, yaraynta samaynta dhoobada, iwm.
Adkeynta ciidda:Adkeynta ciidda iyo hagaajinta, polyacrylamide waxaa loo isticmaali karaa si loo hagaajiyo xasilloonida iyo iska caabbinta daxalka ee ciidda, taas oo hagaajinaysa sifooyinka jirka ee ciidda.
Waa in la ogaadaa in qiyaasta polyacrylamide waa in si taxadar leh loo xakameeyo inta lagu jiro isticmaalka si looga fogaado saameynta xun ee deegaanka. Intaa waxaa dheer, codsiga gaarka ah wuxuu ku xiran yahay shuruudaha gaarka ah ee daaweynta biyaha iyo sifooyinka tayada biyaha.
