Poly Aluminium Chloride inoshanda sei?

Munyika yekurapa mvura,Poly Aluminium Chloride(PAC) yave chinhu chinosanganisa mvura nemagetsi uye chinoshanda zvakanaka. Nekushandiswa kwayo zvakanyanya mukuchenesa mvura yekunwa nemidziyo yekuchenesa mvura yakasviba, PAC iri kuita mafungu nekuda kwekugona kwayo kujekesa mvura nekubvisa tsvina. Muchinyorwa chino, tichaongorora mashandiro ePAC nekukosha kwayo mukurapa mvura.

Kemikari Iri Kuseri kwePAC:

Poly Aluminium Chloride ikemikari inoumbwa nearuminiyamu nechlorine, ine fomura inonzi AlnCl(3n-m)(OH)m. Hunhu hwayo hunoshandiswa zvakasiyana-siyana hunobva pakuti inogona kuvapo mumhando dzakasiyana zvichienderana nehuwandu hwearuminiyamu-ku-chloride uye mwero wepolymerization. Kusiyana uku kunobvumira PAC kuti ikwanise kuchinjika kune matambudziko akasiyana-siyana ekurapa mvura.

Kubatana uye Kubatana:

Basa guru rePAC mukurapa mvura nderekusungana uye kupwanyika. Kana PAC ikaiswa mumvura isina kucheneswa, inonyungudika. Munguva iyi, inogadzira aluminium hydroxide flocs, iyo inoshanda zvikuru pakubata tsvina yakasungirirwa mumvura. Aluminum hydroxide flocs inoshanda semagineti madiki, ichikwevera nekubatanidza zvidimbu zvakaita sevhu, mabhakitiriya, uye zvinhu zvipenyu.

Kubviswa Kwetsvina:

Nzira yePAC yekubatanidza mvura nekuisa mvura mufiriji inobatsira kubvisa tsvina dzakasiyana-siyana mumvura, kusanganisira zvinhu zvakanyungudutswa, macolloid, uye kunyange zvimwe zvinhu zvakanyungudutswa. Sezvo mafiriji achikura uye achirema, anogara pasi petangi rekuchenesa mvura kuburikidza nekupwanyika kwemvura kana kuti anobatwa zviri nyore nemafirita. Izvi zvinoita kuti mvura yakachena uye yakachena ibudiswe.

pH Kusapindirana:

Chimwe chezvakanakira zvikuru zvePAC ndechekuti haina pH neutralite. Kusiyana nezvinhu zvinobatanidza mvura zvakaita sealuminium sulfate kana ferric chloride, izvo zvinogona kuchinja pH yemvura zvakanyanya, PAC inochengetedza pH mazinga ayo akadzikama. Izvi zvinoderedza kudiwa kwemamwe makemikari ekugadzirisa pH, zvichiita kuti kurapwa kuve nyore uye kuderedza mari.

Mabhenefiti ekushandisa PAC:

Kushanda Nesimba: PAC inoshanda zvinobudirira munzvimbo dzakasiyana-siyana dzemvura uye matope.

Kushandiswa kwemvura yakawanda: Inogona kushandiswa pakuchenesa mvura yekutanga neyechitatu.

Zvisaririra Zvishoma: PAC inogadzira zvinhu zvishoma zvetsvina, zvichideredza mari yekurasa tsvina.

Inochengetedza Mari: Kushanda kwayo zvakanaka uye kusapindirana kwepH kunoita kuti ive sarudzo inodhura zvishoma kune zvivakwa zvekuchenesa mvura.

Kuchengeteka: PAC inowanzoonekwa seyakachengeteka kubata kupfuura mamwe macoagulant.

Mashandisirwo ePAC:

PAC inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, anosanganisira kugadzirisa mvura yemumaguta, kugadzirisa mvura yakasviba mumaindasitiri, uye kunyangwe mumaindasitiri emapepa nemachira. Kukwanisa kwayo kubvisa tsvina dzakasiyana-siyana kunoita kuti ive chishandiso chakakosha chekuona kuti mvura yakachena uye yakachengeteka.

Mukupedzisa, Poly Aluminium Chloride (PAC) mushonga unoshamisa wekurapa mvura unoshanda kuburikidza nekuonda uye kupwanyika. Kushanda kwayo, kushanduka-shanduka, uye kusapindirana kwepH kwakaita kuti ive sarudzo inofarirwa munzvimbo dzekurapa mvura pasi rese. Sezvo kudiwa kwemvura yakachena kuri kuramba kuchikura, PAC ichiri mutambi mukuru mukuona kuti nharaunda pasi rose dzinowana mvura yakachengeteka uye inonwiwa.
