Munguva pfupi yapfuura, kambani yedu yakaita chiitiko chekusimudzira munaGunyana uye yakaburitsa zviitiko zvinotevera zvinosarudzwa: Water Decoloring Agent nePAM zvinogona kutengwa pamwe chete nemutengo wakaderedzwa mutengo.
Kune mhando mbiri huru dzezvinhu zvinobvisa ruvara mukambani yedu. Mushonga wekubvisa ruvara wemvura CW-08 unonyanya kushandiswa kurapa mvura yakasviba kubva mumachira, kudhinda nekudhaya, kugadzira mapepa, pendi, pigment, dyestuff, inki yekudhinda, makemikari emarasha, petroleum, petrochemical, kugadzira coking, mishonga yezvipembenene nedzimwe nzvimbo dzemaindasitiri. Vane hunyanzvi hwepamusoro hwekubvisa ruvara, COD neBOD. Mushonga wekubvisa ruvara CW-05 unoshandiswa zvakanyanya mukugadzira nzira yekubvisa ruvara rwemvura yakasviba.
Dzinonyanya kushandiswa pakurapa mvura yakasviba pakugadzira machira, kudhinda, kudhaya, kugadzira mapepa, kugadzira migodhi, inki nezvimwewo. Dzinogona kushandiswa pakurapa kubvisa mavara emvura yakasviba ine ruvara rwakawanda kubva mumiti yedhaya. Dzakakodzera kurapa mvura yakasviba nedhaya yakabatidzwa, ine acid uye inopararira. Dzinogonawo kushandiswa pakugadzira mapepa ne pulp semushonga wekuchengetedza. Kuti uwane misiyano chaiyo, unogona kutibata kuti tipe mhinduro dzakananga.
Zvichienderana nehunhu hwemaion, tinecationic polyacrylamideCPAM, anionic polyacrylamide APAM uyepolyacrylamide isiri ionicNPAM. Tinokurudzira kuti kana PAM yanyungudutswa kuita mvura yetsvina, iise mumvura yetsvina kuti ishandiswe, mhedzisiro yacho iri nani pane kuiisa zvakananga. Cleanwat Polyacrylamide PAM ipolymer inonyungudutswa mumvura ine zvakawanda. Hainyunguduke muzvinhu zvakawanda zvinonyungudutswa, ine basa rakanaka rekuisa mvura mutsvina, uye inogona kuderedza kupesana pakati pemvura. Ine mhando mbiri dzakasiyana, hupfu ne emulsion. Pamwe chete nezvimwe zvigadzirwa zvedu, inoshanda zvakanyanya pakurapa tsvina.
Ichi chiitiko chisingawanzoitiki gore rega rega. Tiri kutarisira kugamuchira mibvunzo yenyu munguva pfupi iri kutevera. Tave nebasa guru rekuona zvese zvinodiwa nevatengi vedu zvisinei nehunhu hwewarandi, mitengo inogutsa, kutumira nekukurumidza, kutaurirana nenguva, kurongedza kunogutsa, mitemo yekubhadhara iri nyore, mitemo yekutumira yakanakisa, sevhisi mushure mekutengesa nezvimwewo. Tinopa sevhisi imwe chete uye kuvimbika kwakanyanya kune vatengi vedu vese. Tinoshanda nesimba nevatengi vedu, vatinoshanda navo, vashandi kuti tigadzire ramangwana riri nani.
