Mchenga (malasha) kutsuka coagulant ndi organic polima mankhwala angathandize kukhazikika pamwamba mlandu wa zinyalala (malasha) particles, kuchepetsa mphamvu ya magetsi, ndi chifukwa aggregation ndi mpweya. Ntchito yaikulu ndikulekanitsa matope ndi madzi.
Chogulitsacho ndi madzi owoneka bwino a viscous, m'malo mwa polyaluminium chloride. Amawonjezeredwa kumatope ndi madzi, ophatikizidwa ndi PAM, ndikuyikidwa mu lamba, chimango, kapena centrifuge. Imatha kulekanitsa matope ndi madzi mwachangu, kugwiritsa ntchito bwino madzi abwino, komanso kutulutsa madzi amatope ambiri.
Zofotokozera:
| Kanthu | Mlozera |
| Maonekedwe | Madzi omata opanda mtundu kapena owala |
| Zolimba ≥% | 19-21 |
| PH | 3.0-7.0 |
Kagwiritsidwe ndi chenjezo:
1) Ikhoza kuwonjezeredwa mofanana komanso mosalekeza ku ndondomeko ya madzi otayira pambuyo pothira muyeso iliyonse, kapena kuwonjezeredwa mwachindunji kumadzi otayira pambuyo pothira nthawi 5-20, kugwedezeka, ndi kukhazikika.
2) Pochiza magwero osiyanasiyana amadzi ndi zimbudzi, mlingowo umatsimikiziridwa potengera kusungunuka ndi kuchuluka kwa madzi oyeretsedwa, ndipo mlingo woyenera ukhoza kupezedwa kupyolera mu mayesero ang'onoang'ono.
Kusankhidwa mosamala kwa mfundo za dosing ndi kuthamanga kolimbikitsa ndikofunikira kuonetsetsa ngakhale kusakanikirana ndi zinthuzo ndikupewa kuphwanya kwa floc.
