Two types of seed with different surface area are used in a precipitation system to evaluate the effectiveness of seed surface characteristics on sludge dewatering properties. We expect that the surface area of the seed will stongly affect the sludge properties. The preliminary study shows that the seeded system has a lower precipitation pH and lower supersaturation level.
