Munyika yekurapa mvura, hunyanzvi hunoita basa guru mukuchengetedza hutano hwevanhu nekuchengetedza nharaunda.Polyaluminum chloride, inowanzozivikanwa sePAC, yave mhinduro ine mabasa akawanda uye mashandisirwo, ichichinja nzira yatinochenesa nekutarisira zviwanikwa zvemvura. Muchinyorwa chino, tichaongorora mabasa nekushandiswa kwePAC, tichijekesa kukosha kwayo kuri kukura mumunda wekurapa mvura.
Polyaluminum chloride ikemikari inoshandiswa zvakanyanya se coagulant uye flocculant mukurapa mvura. Inogadzirwa kuburikidza nekuita kwealuminium hydroxide uye hydrochloric acid, zvichikonzera mushonga unochenesa mvura unoshanda uye unoshanda. PAC inowanikwa mumhando dzakasiyana-siyana, kusanganisira mvura uye yakasimba, zvichiita kuti ikwanise kushandiswa zvakasiyana-siyana.
Mabasa ePAC
Kubatana uye Kubatana: Rimwe remabasa makuru ePAC kuungana uye kuungana. Kana ikaiswa mumvura, PAC inogadzira mafloc ealuminium hydroxide ane positive charged. Mafloc aya anokwezva uye anobvisa tsvina uye tsvina iri mumvura, senge zvinhu zvakamiswa, organic matter, uye kunyange mamwe mabhakitiriya. Mafloc paanokura muhukuru, anogara pasi petangi rekuchenesa, zvichiita kuti zvive nyore kubvisa tsvina mumvura.
Kugadziriswa kwepH: PAC inogona kubatsira mukugadzirisa huwandu hwepH yemvura. Nekuwedzera PAC, pH yemvura ine acidic kana alkaline inogona kuwedzerwa mukati mehuwandu hwainodiwa, zvichiita kuti maitiro ekurapa anotevera ashande.
Kuderedza Kusviba: Kusviba, kunokonzerwa nezvimedu zvakasungirirwa, kunogona kuita kuti mvura iite seyakakora uye isingafadzi. PAC inogona kuderedza kusviba zvinobudirira nekubatanidza zvimedu zvakasungirirwa, zvichiita kuti zvigare pasi.
Kubvisa Simbi Inorema: PAC inokwanisa kubvisa simbi dzinorema mumvura, dzakadai searsenic, lead, uye mercury, kuburikidza nenzira inozivikanwa se adsorption. Maflocs ealuminium hydroxide ane positive charged anokwevera uye anosunga nemaion esimbi anorema ane negative charged, zvichiita kuti zvive nyore kubvisa.
Mashandisirwo Akawanda ePAC
Kurapa Mvura yeMunicipal: PAC inoshandiswa zvakanyanya muzvivakwa zvemunicipal kuchenesa mvura yekunwa. Inobatsira kubvisa tsvina, kunatsiridza kuchena kwemvura, uye kuona kuti mvura inosangana nemitemo yekushandiswa zvakachengeteka.
Mashandisirwo Emaindasitiri: Maindasitiri mazhinji anovimba nePAC pakugadzirisa zvinodiwa zvavo zvemvura. Kubva pakugadzirisa mvura yakasviba muindasitiri yemakemikari kusvika pakucheneswa kwemvura inotonhorera mumafekitori emagetsi, PAC inoita basa rakakosha mukuchengetedza mashandiro akanaka uye kutevedzera mitemo yezvakatipoteredza.
Kuchera nekugadzira zvicherwa: Mumabasa ekuchera nekugadzira zvicherwa, PAC inoshandiswa kuparadzanisa zvicherwa zvinokosha kubva mutsvina isingadiwe. Kukwanisa kwayo kunyungudutsa nekugadzika zvinhu zvakasimba kunoita kuti ive chishandiso chakakosha muindasitiri.
Indasitiri yeMapepa neMapundu: PAC inoshanda muindasitiri yepepa nemapundu kubatsira mukujekesa mvura inoshandiswa, zvichikonzera kuvandudzwa kwemhando yepepa uye kudzikira kwekukanganiswa kwezvakatipoteredza.
Indasitiri Yemachira: Vagadziri vemachira vanoshandisa PAC kurapa mvura yakasviba ine madhayi nezvimwe zvinosvibisa. Hunhu hwePAC hwekubatanidza machira nekubvisa madhayi nemafuta akawandisa zvinobatsira kubvisa ruvara nemafuta akaoma, zvichiita kuti mvura ibude zvakanaka kana kushandiswazve.
Polyaluminum chloride, kana kuti PAC, yaratidza kuti ndiyo mhinduro inoshanda uye inokosha munyika yekurapa mvura. Mabasa ayo mukubatanidza mvura, kupwanya mvura, kugadzirisa pH, kuderedza kusvibiswa kwemvura, uye kubvisa simbi inorema zvakaita kuti ive chinhu chakakosha mukuona kuti mvura yakachena inowanikwa munharaunda nemaindasitiri. Sezvo kukosha kwemhando yemvura uye kuchengetedzeka kwezvakatipoteredza kuri kuramba kuchiwedzera, kukosha kwePAC mumakemikari ekurapa mvurayagadzirira kusimuka, zvichiita kuti ive chishandiso chakakosha mukuwana ramangwana rine hutano uye rinogara kwenguva refu.
