Activated sludge is a term used both to refer to a widely utilized wastewatertreatmentprocess, and to the solid com-pounds which result from that process.
The activated sludge technique is one of the most commonly used methods for handling human waste in municipal settings around the world, and it can also be employed in the treatment of industrial wastewater.
The goal is to remov
treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-treatmentprocess - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasin

The goal is to remov
in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (grease and oils).
Efficiencies:
Suspended solids 50 – 65%
BOD 30 – 35%
Primary clarifiers are either circular or rectangular. They are very similar to sedimentation basins used in watertreatment except that scum removal is always provided in addition to sludge collection.
