Txhua yam dej haus yuav raug kho los ntawm cov dej uas los ntawm qhov chaw, uas feem ntau yog pas dej qab zib, dej ntws, dej qhov dej, lossis qee zaum txawm tias yog kwj deg thiab cov dej los ntawm qhov chaw tuaj yeem raug cov kuab paug tsis tau xav txog lossis txhob txwm ua thiab kev hloov pauv ntawm huab cua lossis lub caij nyoog. Kev saib xyuas qhov zoo ntawm cov dej los ntawm qhov chaw ces nws ua rau koj kwv yees tau qhov kev hloov pauv rau cov txheej txheem kho.
Kauj Ruam Ib: Kev kho ua ntej rau cov dej qhov chaw, tseem hu ua Coagulation thiab Flocculation, cov khoom me me yuav raug sib xyaw nrog cov tshuaj lom neeg los ua cov khoom loj dua, tom qab ntawd cov khoom loj dua yuav poob rau hauv qab.
Kauj ruam thib ob yog Kev lim dej, tom qab ua kom cov dej noo hauv kev kho ua ntej, cov dej ntshiab yuav dhau los ntawm cov lim dej, feem ntau, cov lim dej yog tsim los ntawm xuab zeb, pob zeb, thiab thee) thiab qhov loj ntawm qhov. Txhawm rau tiv thaiv cov lim dej, peb yuav tsum saib xyuas qhov turbidity, cov khoom dais, alkalinity thiab lwm yam dej zoo.
Kauj ruam thib peb yog cov txheej txheem tua kab mob. Kauj ruam no tseem ceeb heev, tom qab lim dej lawm, peb yuav tsum ntxiv cov tshuaj tua kab mob rau hauv cov dej lim, xws li chlorine, chloramine, nws yog qhov yuav tsum tau tua cov kab mob, cov kab mob me me, thiab cov kab mob uas tseem tshuav, xyuas kom meej tias dej muaj kev nyab xeeb thaum xa mus rau tsev.
Kauj ruam thib plaub yog kev faib tawm, peb yuav tsum ntsuas pH, turbidity, hardness, residual chlorine, conductivity (TDS), ces peb thiaj paub txog tej kev pheej hmoo lossis kev hem thawj rau kev noj qab haus huv pej xeem raws sijhawm. Tus nqi chlorine seem yuav tsum tshaj 0.3mg/L thaum raug xa tawm ntawm lub chaw tsim dej haus, thiab tshaj 0.05mg/L thaum kawg ntawm lub network yeeb nkab. Turbidity yuav tsum tsawg dua 1NTU, tus nqi pH yog ntawm 6.5 ~ 8,5, yeeb nkab yuav xeb yog tias tus nqi pH tsawg dua 6.5pH thiab yooj yim ntsuas yog tias pH tshaj 8.5pH.
Txawm li cas los xij, tam sim no, kev ua haujlwm ntawm kev saib xyuas dej zoo feem ntau siv kev tshuaj xyuas tes hauv ntau lub tebchaws, uas muaj ntau qhov tsis zoo ntawm kev ua haujlwm tam sim ntawd, tag nrho, kev sib txuas lus thiab kev ua yuam kev ntawm tib neeg thiab lwm yam.
