Flive ndiyo nzira iyo iyo yakasarudzika yakarongedzwa zvimedu zvakamiswa zvimedu zviripo mumvura yakagadzikana mumvura inoiswa. Izvi zvinowanikwa nekuwedzera kakawanda chinobhadharwa mari. Iyo yekubhadhara yakanaka mune yekuwirirana kumutswa nemhosva isina kunaka iripo mumvura (kureva kuzviitira iwe). Kamwe chete zvimedu zvakarongeka kana zvisina kurapwa, maitiro ekurima anoitika. Iyo inogadziriswa masisitimu anosanganisira zvidimbu zvakakura uye zvakakura kusvika zvazviremerwa zvakakwana kuti ugadzirise neyekunyora kana akakura zvakakwana kuti vatambure mhepo mabhuru.
Nhasi isu tichazotarisisa pane furcculation zvivakwa zviviri zvinowanzo famba: poly aluminium chloride uye aluminium sulfate.
Aluminium Sulfate: Aluminium Sulfate ndeye acidic mune zvakasikwa. Iyo inoshanda nheyo yeAluminium Sulfate iri seinotevera: Aluminium Sulfate inoburitsa aluminium hydroxide, al (0h (0h) 3. Aluminium Hydroxides ane mashoma ph range, pamusoro pazvo hadzinganyatso hydrolysis kana, hydrolyzated aluminium hydroxides. . Iyo alkalinity mumvura inofanira kuve yakakwana panguva yekubhadhara mari yekuve nechokwadi chekuti iyo insoluble hydroxide inoumbwa zvizere uye yakagadzirirwa. Inobvisa mavara uye collidal midziyo kuburikidza nekubatanidzwa kwe adsorption uye hydrolysis on / kuita simbi hydroxides. Naizvozvo, iyo yekushandisa phwindo yeAluminium Sulfate iri chaizvo 5.8-8.5, saka zvakakosha kuti uve nechokwadi chechokwadi ph kutonga mukati meiyo aluminium sulfate.
Polandauminum chloride(Pac) ndeimwe yemakemikari ekurapa emvura anoshandiswa mukushandiswa nhasi. Iyo inoshandiswa zvakanyanya mumvura yekunwa uye kurapwa kwemvura nekuda kwekunetseka kwayo kwekunyora uye yakanyanya kuwanda yePH uye tembiricha yekunyorera ichienzaniswa nemimwe makemikari ekurapa emvura. Pac inowanikwa mumakadhi akati wandei neAlumina constations kubva 28% kusvika 30%. Alumina Constrenration haisi iyo chete yekufunga kana ichisarudza iyo giredhi rePac kuti ishandise.
Pac inogona kutariswa seye pre-hydrolysis coagulant. Iyo pre-hydrolysis aluminium masango ane yakanyanya kunaka yekubhadhara mari yekushomeka, inogadzira iyo pac yakawanda cationic kupfuura alumminer isimba yakasimba yekubhadhara zvisina kunaka yakamiswa mumvura.
Pac ine zvinotevera zvinotevera zvakanakira Aluminium Sulfate
1. Izvo zvinoshanda pakadzika kwazvo enjoenti. Sezvo mutemo wegunwe, iyo pac dosi iri anenge chikamu chimwe muzvitatu cheiyo dofo inodiwa kuti a alum.
2. Izvo zvinosiya zvishoma zvakasara aluminium mumvura yakabatwa
3. Inogadzira kushoma sludge
4. Izvo zvinoshanda pamusoro peiyo yakafara ph range
Kune akawanda marudzi emafudzi, uye chinyorwa ichi chinongotuma zviviri zviviri. Kana uchisarudza kanokona, iwe unofanirwa kufunga nezveMvura mhando iwe uri kurapa uye yako yako mutengo bhajeti. Ndinovimba une ruzivo rwakanaka rwemvura kurapwa. Semunhu anorapwa kwemakemikari emakemikari ane makore 28 echiitiko. Ndiri kufara kugadzirisa matambudziko ako ese (nezvechemical emvura).
