Soil deposition on fibers was investigated from the standpoint of the waste water treatment. Polyethylene, poly (vinylidene chloride), poly (vinylidene fluoride), polyethylene terephthalate and nylon 6 fibers were used as soil collectors. Following immersion of the fibers in water from Sarusawa pond, water turbidity was measured. Turbidity decreased due to the deposition of soil onto the fiber surfaces. Poly (vinylidene chloride) fibers were more effective as a soil collector than any other fibers.
Particle deposition from an aqueous solution was investigated using a model system consisting of spherical polyethylene or nylon particles and a polymeric plate. The plate was perpendicularly immersed in an aqueous suspension. The number of particles deposited on the plate appeared related to the polar components of surface free energies of the particle and plate. The results of particle deposition in the model system were in good agreement with those in systems using water from a pond.
