Polyaluminium chlorideimuchina wekuchenesa mvura unoshanda zvikuru, unoshandiswa zvakanyanya mukuchenesa tsvina yemumaguta uye mukuchenesa mvura yakasviba yemumaindasitiri. Une hunhu hwekushanda nesimba uye kugadzikana. Patinotaura nezvePAC, chimwe chezviratidzo zvinowanzotaurwa nezvacho inyaya yekuva basicity. Saka chii chinonzi basicity? Chii chinoita kuti basicity ive nemhedzisiro pamhando yepolyaluminium chloride? Kunzwisisa pfungwa iyi kuchave nemhedzisiro huru pakusarudzwa kwepolyaluminium chloride.
Chii chinonzi basicity mu polyaluminium chloride?
MuPAC, basicity inoreva molar ratio yehydroxyl groups kune aluminum ions. Inowanzo tsanangurwa se basicity (B):
B = [OH]-] / [Al3+]
Basicity chimwe chezviratidzo zvakakosha zve polyaluminium chloride. Inokanganisa zvakananga flocculation effect yePAC.
Kambani yedu inopa mhando dzakasiyana dzePAC dzine hunhu hwepakutanga kubva pa40% kusvika 90%.
Maitiro ekushandiswa kwesimba rebasicity pa polyaluminium chloride
Kushanda kwechinhu chinobva muzvinhu zvidiki (Basicity) kunokanganisa mashandiro ePAC nekuchinja chimiro chepolymer uye kugoverwa kwechaja kwePAC. Alkalinity ndiyo inosarudza mwero wekuumbwa kwealuminium hydroxyl complexes muPAC. Kushanda kwechinhu chidiki (high basicity) kunobatsira pakuumbwa kwePAC ine polymerization yakakwira uye kunovandudza flocculation effect yayo. Uye kushanda kwechinhu chidiki (basicity) kuchakanganisa kugoverwa kwechaja yakanaka kwePAC uye kugona kwayo kunyudza zvinhu zvine negative charge.
Mhedzisiro yekuva nepfungwa shoma paPAC:
Kushanda kwakakodzera kunogona kuwedzera simba re polyaluminium chloride pakuyerera kwemvura. Kushanda kwakaderera kuchaita kuti PAC isakwanise kuyerera zvakanaka uye kuderedza simba rekufamba kwemvura.
Kuomarara kunokanganisawo saizi, huwandu uye mwero wekuomarara kwepolyaluminium chloride condensed flocs. Kuomarara kwakakodzera kunogona kubata izvi zvakanaka.
Saka, zvakakosha zvikuru kusarudza modhi yePAC yakakodzera zvichienderana nezvaunoda.
Tinogona kupa mamodheru ePAC anotevera:
| Chinhu | PAC-I | PAC-D | PAC-H | PAC-M | PAC-G |
| Chitarisiko | Upfu hweyero | Upfu hweyero | Upfu chena | Upfu hwemukaka | Upfu hwakachena hwemukaka |
| Zviri Mukati (%, Al2O3) | 29±1 | 30±1 | 30±1 | 30±1 | 30±1 |
| Huwandu (%) | 40 - 90 | 40 - 90 | 40 - 90 | 40 - 90 | 40 - 90 |
| Zvinhu zvisinganyunguduki mumvura (%) | 1.0 MAX | 0.6 MAX | 0.6 MAX | 0.6 MAX | 0.6 MAX |
| pH | 3.0 – 5.0 | 3.0 – 5.0 | 3.0 – 5.0 | 3.0 – 5.0 | 3.0 – 5.0 |
Tinoita kutonga kwakasimba kwemhando yepamusoro pamafekitori edu e polyaluminium chloride uye tinogona kupa mazano chaiwo emhando zvichienderana nezvinodiwa nevatengi vedu, tichipa vatengi PAC yepamusoro inoenderana nezvinodiwa zvavo. Chikwata chedu chekutengesa chine ruzivo rwakakura mukusarudza zvigadzirwa uye chinogona kupa vatengi mazano ehunyanzvi uye sampuro dzakanyatsokodzera kuti vatengi vaite bvunzo dzebeaker.
Kana uchitsvaga munhu akavimbikaMutengesi wePACPakucheneswa kwemvura yekunwa, kugadziriswa kwemvura yakasviba mumaindasitiri kana zvimwe zvinoshandiswa, tinogona kupa PAC yakasarudzika kuti ienderane nezvaunoda. Taura nesu izvozvi kuti udzidze zvakawanda nezvezvigadzirwa zvedu zvePAC zvinoshanda uye uwane mutengo unokwikwidzana!
