Alum increases the rate of sedimentation because,alum being an external agent causes the particles present in the container to colloid together and form heavier particles, as heavier particles sink in water these particles settle down therefore,increasing the speed of sedimentation. This is also known as loading or coagulation.
Eg;
Muddy water====alum is added====impurities settles down====clean water.

As, we know that Alum increases the rate of sedimentation.
Alum (aluminum sulfate) is added to the water to destabilize natural fine particulate matter suspended in water.
This process in known as coagulation.
The addition of alum causes these particles and colloids to clump together to form heavier particles which will settle in water.
