Kugadziriswa kwemvura yetsvina inzira yakakosha yekuona kuti mvura yakachena uye yakachengeteka kuti ishandiswe nevanhu uye kuchengetedza nharaunda.Nzira dzechinyakare dzekuchenesa mvura dzakavimba nekushandiswa kwemakemikari coagulants, zvakadai sealuminium uye iron salts, kubvisa tsvina mumvura.Zvisinei, izvimaindasitiri mvura kurapwa makemikaridzinodhura, dzine simba guru, uye dzinogona kuva nemigumisiro yakaipa yezvakatipoteredza.
Neraki, mhinduro nyowani yakabuda mumunda wekuchenesa tsvina -polyamines(PA).Polyamines iboka remakomboni ane organic anowanikwa mumasero mapenyu uye ane zvimiro zvakasiyana zvinoita kuti ashande zvakanyanya mukuchenesa mvura.Kushandiswa kwema polyamines kuri kushandura nzvimbo yekuchenesa mvura yetsvina uye nekupa mhinduro yakagadzikana uye inoshanda kune matambudziko ekusvibiswa kwemvura uye kushomeka.
China ndeimwe yevatengi vakakura kwazvo vemakemikari ekuchenesa mvura pasi rose, ine kudiwa kuri kukurumidza kukura kweanoshanda uye anodhura ekugadzirisa tsvina yemvura.Kushandiswa kwema polyamines muindasitiri yekuChina yekuchenesa mvura yetsvina kuri kuwedzera kusimba nekuda kwekuita kwavo kwepamusoro uye kudhura-zvichienzanisa nemakemikari echinyakare.
Polyamines ine akati wandei mabhenefiti pamusoro pechinyakare maindasitiri ekurapa mvura makemikari.Imwe yemabhenefiti makuru kushamwaridzana kwavo kwepamusoro kune zvakasiyana-siyana zvinosvibisa zvinowanikwa mumvura yetsvina, senge simbi dzinorema, dhayi, uye organic komisheni.Polyamines inogona kunyatso batana uye kuyerera izvi zvinosvibisa, zvichikonzera kubviswa kwavo nyore kubva mumvura.Iyi nzira inovandudza zvakanyanya kushanda kwese kweiyo nzira yekuchenesa mvura yetsvina, zvichiita kuti pave nani kunaka kwemvura.
Imwe mukana we polyamines ndeye yakaderera dosage chinodiwa.Polyamines inogona kuwana yakaenzana nhanho yekubvisa tsvina semakemikari echinyakare muhuwandu hudiki, zvichikonzera kuchengetedzeka kukuru kwemari yekuchenesa mvura yetsvina.Uyezve, kushandiswa kwema polyamines kunogona kuderedza kuwanda kwemarara anogadzirwa panguva yekurapa, izvo zvinogona kuwedzera kuderedza mari yekushanda.
Pakupedzisira, kushandiswa kwePA mukugadziriswa kwemvura yetsvina kuri kushandura nzvimbo yekuchenesa tsvina uye kupa mhinduro yakagadzikana uye inoshanda kune matambudziko ekusvibiswa kwemvura uye kushomeka.Nekuwedzera kuri kuda kwemhinduro dzinoshanda uye dzinodhura dzekuchenesa mvura yetsvina muChina, kushandiswa kwema polyamines muindasitiri yekuchenesa mvura yetsvina kunotarisirwa kuwedzera mumakore anotevera, ichipa nharaunda yakachena uye yakachengeteka kune vese.
