What are filter aids
Kieselguhr is a successful filter aid and as little as 0.1 percent can be added to the slurry. The rate of filtration is increased by 5 times or more, at the above concentration, though the slurry contains 20% solids. Handling of filter aids: Filter aids are mostly used for clarification processes, i.e., where solids are discarded.

Role of Polyelectrolytes in Filtration Processes
Several polymers were tested in jar tests for their potential as filter aids. Primafloc C-7 was selected for further study. Filter beds were precoated with polymer prior to each run. Filter beds were com- prised of coarse sand with a size of 1.3 mm (geometric mean of adjacent sieve sizes) and had a depth of 5.5 inches.

PERLITE
Perlite filter aids provide users with a lightweight material choice. Perlite filter aid grades provide the user with a density advantage from 20 to 50% over other types of filter aids. Perlite filter aid dry density ranges from 100 to 200 kg/m3 (6 to 12 lb/ft3), and the filter cake density range is 100 to 270 kg/m3 (7 to 17 lb/ft3).
