Izisombululo ezingama-25 eziqhelekileyo zengxaki yetekhnoloji ye-osmosis ebuyela umva (Icandelo lesi-3)

13. Yintoni ungcoliseko lwamasuntswana kunye ne-colloid? Ukulinganisa njani?

Nje ukuba i-particle kunye ne-colloid contamination yenzeke kwi-osmosis eguqukayo okanye kwiinkqubo ze-nanofiltration, inokuchaphazela kakhulu ukuveliswa kwamanzi kwi-membrane kwaye ngamanye amaxesha inciphise izinga lokukhupha ityuwa. Iimpawu zokuqala zokungcoliswa kwe-colloidal kukwanda koxinzelelo lwenkqubo, kwaye imithombo yamasuntswana okanye i-colloids kwi-membrane inlet inlet umthombo wamanzi iyahluka ukusuka kwindawo ukuya kwindawo, ngokuphindaphindiweyo kuquka iintsholongwane, i-sludge, i-silicon ye-colloidal, iimveliso ze-iron corrosion, njl. isuswe ngempumelelo kwitanki yokucacisa okanye isihluzo esiphakathi. Ukongeza, i-cationic polymeric dielectrics inokuphinda isebenze kunye ne-anionic scale inhibitors, kwaye i-precipitates yabo inokungcolisa amacandelo e-membrane. I-SDI15 isetyenziselwa ukuvavanya ukuthambekela kokungcoliswa okunjalo okanye unyango lwangaphambili emanzini. Nceda ujonge kwintshayelelo eneenkcukacha kwizahluko ezifanelekileyo.

14. Kude kube nini ukuvalwa okuphezulu okuvunyelweyo ngaphandle kokugungxulwa kwenkqubo?

Ukuba inkqubo isebenzisa i-scale inhibitors, xa ubushushu bamanzi buphakathi kwe-20-38 ℃, kuthatha malunga neeyure ezi-4; Malunga neeyure ezisi-8 ngaphantsi kwe-20 ℃; Ukuba inkqubo ayisebenzisi i-scale inhibitors, iya kuthatha malunga nosuku olu-1.

15. Ukusetyenziswa kwamandla kwenkqubo ye-membrane kungancitshiswa njani?

Izinto ezisezantsi zokusetyenziswa kwe-membrane zanele, kodwa kufuneka kuqatshelwe ukuba izinga labo lokukhupha ityuwa lingaphantsi kancinane kunezinto eziqhelekileyo ze-membrane.

Iyakwazi ukudlula ngokukhululekileyo kwi-membrane ye-microfiltration, esetyenziselwa ukususa ibhaktheriya, i-micro flocs, okanye i-solids suspended totals (TSS). Uxinzelelo oluqhelekileyo kumacala omabini e-membrane yi-1-3 bar

16.Ingaba i-reverse osmosis isixokelelwano samanzi acocekileyo sihlala siqala kwaye sime?

Inkqubo ye-membrane iyilwe ngokusekelwe ekusebenzeni okuqhubekayo, kodwa ekusebenzeni okwenyani, kuya kuhlala kukho i-frequency ethile yokuqalisa kunye nokuvala. Xa inkqubo ye-membrane ivaliwe, kuyimfuneko ukusebenzisa amanzi awo avelisiweyo okanye amanzi asele ecociwe ngaphambili ukugungxulwa koxinzelelo oluphantsi ukubuyisela ugxininiso oluphezulu lwamanzi aqulethe izithinteli zesikali ezivela kumalungu enwebu. Kufuneka kuthatyathwe amanyathelo okuthintela ukuvuza kwamanzi kwisixokelelwano kunye nokuqaliswa komoya, ngokungathi icandelo liyavuza kwaye lome, kunokubangela ilahleko engenakulungiseka yokukhutshwa kwamanzi. Ukuba ukuvalwa kungaphantsi kweeyure ezingama-24, akukho mfuneko yokuthatha amanyathelo okuthintela ukukhula kwe-microbial. Kodwa ukuba ixesha lokuvala lidlula le migaqo ingentla, ulwelo olukhuselayo kufuneka lusetyenziselwe ukugcinwa kwenkqubo okanye ukugungxulwa kwexesha le-membrane system.

17.Indlela yokumisela isalathiso sokufakela amakhonkco okutywina amanzi etyuwa kumalungu e-membrane?

Umsesane wokutywina wamanzi etyuwa kwi-membrane element iyafuneka ukuba ifakwe kwi-inlet end of the element, kunye nokuvula okujongene ne-inlet direction. Xa isitya soxinzelelo sizaliswe ngamanzi, ukuvula kwayo (i-lip edge) kuya kuvuleka ngakumbi, ukutywina ngokupheleleyo ukuhamba kwecala lamanzi ukusuka kwi-membrane element ukuya eludongeni lwangaphakathi lomkhumbi woxinzelelo.

18.Uyisusa njani isilicon emanzini?

I-silicon emanzini ikhona ngeendlela ezimbini: i-silicon esebenzayo (i-silicon ye-monomeric) kunye ne-silicon ye-colloidal (i-polysilicon): i-silicon ye-colloidal ayinayo iimpawu ze-ion, kodwa inomlinganiselo omkhulu. I-silicon ye-Colloidal inokubanjwa ngeenkqubo zokuhluza kakuhle ngokomzimba, njenge-osmosis eguqukayo, kunye nomxholo wamanzi unokuncitshiswa ngetekhnoloji ye-coagulation, njengamatanki okucacisa i-coagulation. Nangona kunjalo, iitekhnoloji zokuhlukana ezixhomekeke kwiimpawu zentlawulo ye-ion, ezifana ne-ion exchange resins kunye neenkqubo eziqhubekayo ze-electrodeionization (CDI), zinokusebenza okulinganiselweyo ekususeni i-silicon ye-colloidal.

Ubungakanani besilicon esebenzayo buncinci kakhulu kunobo besilicon ye-colloidal, ngoko ke uninzi lwetekhnoloji yokucoca ngokomzimba njengokucaciswa kwe-coagulation, ukuhluzwa, kunye nokujikeleza komoya akunakususa isilicon esebenzayo. Iinkqubo ezinokususa ngempumelelo i-silicon esebenzayo ziquka i-osmosis eguqukayo, i-ion exchange, kunye ne-electrodeionization eqhubekayo.
