Indasitiri ichaita zvisingadzivisiki kuti ibudise nhamba huru yetsvina, tsvina ine mafuta, yakaturikwa yakaoma, inorema simbi, uye zvimwe zvinokuvadza zvinhu uye furo, kubudiswa kwakananga kuchasvibisa nharaunda yakapoteredza. Iyo Environmental Monitoring Bureau ine zvakakwirira zvinodikanwa pakurapwa kwetsvina uye kuyedzwa kwakasimba. Iyo nzira yekuchenesa mvura yetsvina yakaoma, uye zviri nyore kusangana nematambudziko efuro mukurapwa.

Sewage kurapwa maererano nechiyero chekuparadzanisa, yakakamurwa kuva imwe, maviri, matatu kurapwa kwemvura. Nekudaro, nekuda kweiyo nzira yekurapa uye kunaka kwetsvina, iyo nzira yekuchenesa tsvina iri nyore kuvhuvhuta, inova iyo inoda kushandisa sewage treatment defoamer ye defoaming.

Sewage kurapwa ingave furo rinokonzerwa nemvura yemhando yezvikamu, kana furo rinokonzerwa nemaitiro ekurapa. Kwete kurapwa kwenguva yakakodzera kuchava nemigumisiro yakaipa pahutano hwehutano, hunokanganisa kubuda kwehutano hwemvura. Kuti ugadzirise dambudziko rehuputi mumvura yetsvina, kuwedzera defoamer inzira yakanaka.
Zvinoenderana nehunhu hwe tekinoroji yekuchenesa tsvina uye mhando yemvura, iyo sewage yekurapa defoamer yakagadziridzwa iri yakadzika fomula ye defoamer inoumbwa nepolyether uye silicone. Iyo defoamer inogadzirwa nenyanzvi defoamer mainjiniya, ine yakanaka pertinence, uye inogona kugadzirisa akasiyana furo matambudziko mukurapwa kwetsvina. Iyi defoamer inogadzirwa nemhando yepamusoro yezvigadzirwa, iyo formula yekumisikidza yakakwira, uye inogona kuwedzerwa zvakananga mukugadzirisa tsvina. Chete mari shoma inodiwa kuti uwane yakanaka defoaming mhedzisiro. Zvinoenderana neakasiyana masisitimu efuro uye furo huwandu, huwandu hunowedzerwa sezvakakodzera; Paunenge uchishandisa, shandisa 1 kusvika 5 nguva yemvura dilution kuti uwedzere kana kuwedzera zvakananga (zviri nyore kuisa mushure mekudzikiswa, inoda kushandisa nekukurumidza sezvinobvira), unogona zvakare kubvunza mugadziri kuti ashandise chaiyo.
