Jecha (marasha) wekugeza coagulant ndeye organic polima chigadzirwa chinogona kubatsira kudzikamisa kubhadharisa kwepasi pesediment (marasha) zvimedu, kuderedza kugona kwemagetsi, uye kukonzera kuunganidzwa uye kunaya. Basa guru nderekuparadzanisa madhaka nemvura.
Chigadzirwa chacho chiri pachena viscous fluid, ichitsiva polyaluminium chloride. Inowedzerwa kumatope nemvura, yakasanganiswa nePAM, uye yakaiswa mubhandi, furemu, kana centrifuge. Inogona kukurumidza kupatsanura madhaka nemvura, kushandisa zvakanaka kunaka kwemvura, uye kuwana mazinga akakwirira ekubvisa madhaka.
Zvinodiwa:
| Item | Index |
| Chitarisiko | Mvura inonamira isina ruvara kana chiedza-ruvara |
| Solid content ≥% | 19-21 |
| PH | 3.0-7.0 |
Kushandiswa uye kudzivirira:
1) Inogona kuve yakaenzana uye inoramba ichiwedzerwa kune yakasvibiswa nzira yekurapa mushure mekucheneswa mune chero chikamu, kana yakananga yakawedzerwa kumvura yakasvibiswa mushure mekunatswa 5-20 nguva, yakamutswa, uye yakagadzika.
2) Pakurapa kwakasiyana masosi emvura netsvina, muyero unotarwa zvichibva pane turbidity uye kusungirirwa kwemvura yakagadziriswa, uye iyo yakakwana dosage inogona kuwanikwa kuburikidza nediki-scale miedzo.
Kuchenjerera kusarudzwa kwemapoinzi edosing uye kumhanyisa kumhanya kunodiwa kuti uve nechokwadi chekusanganiswa nezvinhu uku uchidzivirira kupwanya kwefloc.
