Mashruucyada daaweynta bullaacadaha diatomite, habab kala duwan sida dhexdhexaadinta, qulqulka, xayeysiinta, kala-saarista iyo sifeynta wasakhda ayaa inta badan la sameeyaa.Diatomitewaxay leedahay astaamo jidheed iyo kiimiko oo gaar ah. Diatomite waxay kor u qaadi kartaa dhexdhexaadinta, flocculation, adsorption, sedimentation iyo shaandhaynta wasakhda adag ee la hakiyay ee habka daaweynta bulaacada iyada oo loo marayo habab kala duwan oo wax ka beddel ah sida jeexjeexa, qalajinta, xulashada iyo calcination. Shaqada

Mabda'a aasaasiga ah ee daaweynta bulaacada diatomite:

1. Isdhexgalka dipole inter-particle: Dusha sare ee qaybaha diatomite ayaa lagu soo oogay oo adsorb kara molecules dipolar (atoms) ee warbaahinta polar, taasoo keentay kuwan molecules dipole (atoms) si kedis ah unipolar hanuunin on dusha diatomite. Marka diatomite la geliyo bullaacadaha, dheelitirka polarity ee asalka ah ee nidaamka bulaacada waa la jebiyey, iyo xoogga dipole wuxuu u dhaqmaa si kor loogu qaado ururka walxaha kolloidal iyo molecules polar (atoms) ee wasakhda dusha sare ee dhulka diatomaceous si ay u sameeyaan agglomeration. Si fudud loo kala saaro.

2. Fuuqbaxa: Dulqulku waa hannaan ay qaybo yaryar ama aglomerates qayb ka mid ah qaybaha yar yar ay abuuraan qulqulo waaweyn. Ku darista dhulka diatomaceous ee la beddelay ee bulaacada iyo samaynta kicinta iyo daaweynta gabowga ee nidaamka firidhsan waxay si dhakhso ah u samayn kartaa qulqulo waaweyn oo deggan oo walxaha waxyeelada leh ee bullaacadaha. Tani waa horumar weyn oo ku saabsan kala-soocidda dareeraha adag ee wasakhda, taas oo aan yareynin oo kaliya kharashka xakamaynta wasakheynta, laakiin sidoo kale waxay hagaajinaysaa waxtarka kala-soocidda.

3. Adsorption: Adsorption waa saamayn dusha sare ah. Dusha sare ee dhulka diatomaceous oo leh kala firdhisanaan weyn ayaa leh tamar weyn oo bilaash ah waxayna ku jirtaa xaalad heerkul sare ah oo aan degganayn, sidaa darteed waxay u janjeertaa inay ku dhejiso walxaha kale si loo yareeyo tamarta dusha sare. Dhulka diatomaceous waxa uu xajin karaa kooxda flocculation, qaar ka mid ah fayrasyada bakteeriyada iyo walxaha ultra-fiican ee ku jira wasakhda ilaa dusha sare ee gudaha iyo dibadda ee jidhka diatom, samaynta koox qayb weyn oo ku salaysan jidhka diatom. Intaa waxaa dheer, dhulka diatomaceous sidoo kale waa dhexdhexaad wanaagsan oo loogu talagalay microorganisms, sidaas darteed waxay si fiican u tahay wakiilada microbial ee mashaariicda daaweynta biochemical ee bulaacada.

4. Sifeynta: Diatomite waa mid aan la isku dhejin karin. Ka dib markii qaar ka mid ah diatomite wax laga beddelay lagu daro wasakhda, waxay si dhakhso ah u dejin kartaa si ay u sameyso sariir shaandheyn adag, taas oo ku habboon nadiifinta wasakhda iyo daaweynta ka saarista qashinka. Wasakhda waxaa lagu sifeeyaa sariirta shaandhada si ay fayrasyada waaweyn, fungi, kooxaha fangaska, iyo qaybo ka mid ah la dhexgalo oo laga sifeeyo habka. Taxane wakiilada wasakhda diatomite ee ay soo saartay shirkadeena iyadoo la adeegsanayo tignoolajiyada wax laga beddelay ayaa si weyn loogu isticmaalaa daaweynta wasakhda warshadaha iyo magaalooyinka. Isticmaalayaashu waxay dooran karaan hal ama dhowr tijaabo oo isku dhafan iyadoo loo eegayo shuruudo gaar ah si loo gaaro saameynta la rabo.

Ciidda cad waxaa lagu magacaabaa lakabka saxarka cad ee cawl-cad ee hoostiisa humus. Waxaa loo qaybiyaa dooxooyinka bari ee buuraleyda iyo dooxooyinka Waqooyi Bari Shiinaha, cimiladu waa qoyan, nooca daaqsintuna waa geedo xididaysan oo saliim ah. Isku-ururinta walxaha dabiiciga ah ee ciidda ayaa ka yar kan ciidda madow. Sababtoo ah kala-goynta liidata ee walxaha organic, waxay inta badan leedahay sifooyinka peatification. Waxyaabaha ku jira maadada organic ee lakabka sare ee carrada albic Ilaa 8-10%, qaabka hoose ee lakabka albic inta badan waa dhoobo culus iyo dhoobo; lakabka albic waa mid khafiif ah xagga texture, iyo leaching birta waa mid aad u cad. Macdanta dhoobada ayaa inta badan ah hydromica oo leh qadar yar oo kaolinite ah iyo walax aan caadi ahayn.

Dhulka Diatomaceous wuxuu ka kooban yahay SiO2 amorphous ah, wuxuuna ka kooban yahay qadar yar oo ah Fe2O3, CaO, MgO, Al2O3 iyo wasakh dabiici ah. Dhulka Diatomaceous caadi ahaan waa huruud khafiif ah ama cawl khafiif ah, jilicsan, dalool iyo iftiin. Waxaa caadi ahaan loo isticmaalaa warshadaha sida agabka dahaarka, alaabta shaandhada, buuxinta, alaabta xadhkaha goosta, alaabta ceeriin ee galaaska biyaha, midabaynta iyo sidayaasha kicinta. Qaab dhismeedka daloolsan ee gaarka ah ee dhulka diatomaceous ee dabiiciga ah waxaa lagu arki karaa iyada oo hoos timaada mikroskoob. Qaab-dhismeedkan yar-yar ayaa sabab u ah astaamaha muuqaalka jirka iyo kiimikaad ee dhulka diatomaceous. Qaybta ugu muhiimsan ee dhulka diatomaceous sida side ahaan waa SiO2. Dhulka diatomaceous guud ahaan waxaa sameeyay hadhaagii silicate ka dib dhimashadii algae hal unug ah oo si wada jir ah loogu yeero diatoms, nuxurkeeduna waa SiO2 amorphous biyo ka kooban. Diatoms ee biyaha cusub iyo Waxaa jira noocyo badan oo diatoms ah oo ku noolaan kara biyaha cusbada ah. Guud ahaan, waxa loo kala qaybin karaa “dalabka dhexe” diatoms iyo “habka tuubooyinka” diatoms. Nidaam kasta, waxaa jira "genus" badan, taas oo aad u adag. Qaybta ugu muhiimsan ee dhulka diatomaceous ee dabiiciga ah waa SiO2, kuwa tayada sare leh waa midab cad, iyo maadada SiO2 inta badan waxay ka badan tahay 70%. Diatoms monomer waa mid aan midab lahayn oo hufan. Midabka dhulka diatomaceous wuxuu ku xiran yahay macdanta dhoobada iyo walxaha organic. Halabuurka diatoms ee ilaha macdanta ee kala duwan ayaa kala duwan. Dhulka diatomaceous waa kaydka dhulka diatomaceous fossilized oo la sameeyay ka dib dhimashadii warshad hal unug ka kooban oo la yiraahdo diatom ka dib muddo ururin ah oo ku saabsan 10,000 ilaa 20,000 sano. Diatoms waa mid ka mid ah protists-ka ugu horreeya ee ka soo baxa dhulka, ku nool biyaha badda ama biyaha harada. Waa diatom-kan kaas oo siiya ogsijiinta dhulka iyada oo loo marayo photosynthesis oo kor u qaada dhalashada dadka, xayawaanka iyo dhirta.
