Yedu sludge bhandi sefa yekutsikirira muchina wakabatanidzwa wekukoira dhaka uye kubvisa mvura.Iyo ine hunyanzvi inotora sludge thickener, nekudaro iine yakakura yekugadzirisa kugona uye yakanaka compact chimiro.Zvadaro, mari yemapurojekiti einjiniya inogona kudzikiswa zvakanyanya.Uyezve, iyo sefa yekutsikisa midziyo inochinjika kune akasiyana mazinga edhaka.Inogona kuwana yakanakira kurapwa mhedzisiro, kunyangwe iyo sludge concentration ingori 0.4%.

Mushure mekufamba uye nguva yekumanikidza, iyo slurry inounzwa kune bhandi rine porous yekukora uye giravhiti dewatering.Nhamba yakawanda yemvura yakasununguka inoparadzaniswa negiravhiti, uye ipapo slurry solids inoumbwa.Mushure meizvozvo, slurry inoiswa sandwich pakati pemabhandi maviri akatsikirirwa kuti apfuure nepakati peiyo wedge-yakaita pre-compression zone, yakaderera nzvimbo yekumanikidza, uye yakanyanya kudzvanywa nzvimbo.Inowedzerwa nhanho nhanho, kuitira kuti iwedzere kuparadzaniswa kwesludge nemvura.Pakupedzisira, keke yekusefa inoumbwa uye inobudiswa.
