Changes in surface properties (zeta potential and hydrophobicity) of three
types of soil colloids during activated sludge cultivation are studied. In
the course of all types of soil-colloids’ bioaggregation, a lowering of negative
charge values and an increase of hydrophobicity indexes are observed.
Changes in surface properties of soil aggregates are mostly expressed in
the case of the soil with alkaligenous metabolism trend provided by polypeptides
or acetate substrates.
