Colloidal-chemical Study of Sediment Formed Natural Water on a Microfiltration Membrane
Downloads
The paper presents a colloidal-chemical research of the precipitate formed natural water on a membrane with during microfiltration. Particle sizes in natural water formed on the membrane, the magnitude and sign of the electrokinetic potential were determined by the dynamic light scattering method, and the sedimentation velocity was determined by sedimentation analysis. The coagulating and adsorbing ability of particles suspended in water was identified, which affects the structure of the resulting sediment.
