Mashoko Akakosha: Chinhu chinobvisa ruvara mumvura yakasviba, chinhu chinobvisa ruvara muflocculant
Kana chinhu chinobvisa ruvara rwemvura yakasviba chikapinzwa mutangi remvura yakasviba, chinhu chinoonekwa nemaziso madiki diki chinotanga. Hapana nguva yakatarwa yekuti chinhu chacho chiite zvese; mumamiriro akanaka, chinoshanda mukati memaminitsi, nepo mumamiriro akaomarara emvura, maitiro ese haatore nguva inopfuura hafu yeawa.
Masekondi mashoma ekutanga mushure mekunge chinhu ichi chapinda mumvura ndipo panotanga kupararira nekudzikamisa zvinhu. Pasi pekushanda kwemvura kana kuzungunuka, chinhu ichi chinopararira nekukurumidza, uye mamorekuru anotora zvidimbu zvine mavara mumvura. Mukati memaminitsi angangoita rimwe kana maviri, maflocs madiki anotanga kuumbwa mumvura, uye tsvina yakawanda ine mavara inopedzisa kubatana kwayo kwekutanga.
Maminitsi matatu kusvika mashanu anotevera ndiwo danho rakakosha rekuunganidzwa kwemaruva nekukura. Maruva madiki aya anobonderana uye anoungana, achiwedzera kukura nehukuru sebhora rechando, achiramba achifukidza mavara ari mumvura. Padanho iri, mhedzisiro yekuchinja ruvara rwemavara echinyakare uye mvura yakasviba yemumba inogona kusvika pamusoro pe90%, uye mvura inova yakajeka zvishoma nezvishoma.
Pakupedzisira, danho rekudonha kwevhu nekupatsanurwa rinotanga. Mafuro akagadzirwa anogadzika pasi negiravhiti, kazhinji zvinoda maminitsi mashanu kusvika gumi kuti apedzise kupatsanurwa kwevhu nemvura. Pamvura yakasviba yakaoma kugadzirisa ine madhayi nemafuta, tsvina ine mavara yakaoma kubata, zvichiita kuti nguva yese yekuchinja isvike pamaminitsi gumi nemashanu kusvika makumi maviri.
Mwero wekuita kwechinhu ichi unokanganiswa nemamiriro ezvinhu akasiyana-siyana: kumutswa kwakanyatsonaka kunokurumidza kupararira kwechinhu ichi; nzvimbo yakakodzera isina alkaline mumuviri wemvura inowedzera basa rechinhu ichi; uye tembiricha yakaderera inononotsa kufamba kwechinhu ichi, zvichiita kuti nguva yekuita kwechinhu ichi iwedzere.
Muchidimbu, pamvura yakajairika yakasviba, kuwedzerwa kwezvinobvisa ruvara zvinopedza mhinduro yese mukati memaminitsi gumi kusvika gumi nemashanu, zvichiita kuti mvura iparadzane netsvina; kunyangwe pamvura yakasviba ine mavara akaomarara, maitiro ese ekubvisa ruvara uye kudonha kwevhu kazhinji haapfuure hafu yeawa. Kutevedzana kwezviitiko zvisingawanzoonekwi zvinobata mavara mumvura yakasviba iri mutsvina, zvichijekesa mvura yakasviba uye zvichiita kuti isvike pazvinodiwa.
