cbseacademic.nic.in28 • Flocs are masses of semi -decayed organic matter along with decomposer microbes which are surrounded by slime. They separate the organic matter from waste water. • Flocs settle down in secondary tanks and take part in the formation of sludge. • They can be used as inoculum in biological treatment of waste water as well as

Une dernière décantation (décantation secondaire), permet de débarrasser l'eau épurée des flocs de bactéries. Cette opération se passe dans le clarificateur. L'eau épurée s'en échappe par débordement pour aller ...

Activated Sludge Microbiology Problems and Their Control
www.dec.ny.govHere, no flocs develop and biomass settling does not occur, resulting in a very turbid effluent. The correct remedial action for a dispersed growth problem is a reduction in the F/M of the system, usually done by raising the MLSS concentration. Dispersed growth problems often occur after a toxicity or hydraulic

Jar testing determines how much alum to add to the water in a treatment plant to economically settle out the particles. Jar testing is widely used in industry. FILTRATION Filtration is also another important element of the treatment process. This process involves the water
