Ultrafiltration - Wikipedia

Ultrafiltration can be used for the removal of particulates and macromolecules from raw water to produce potable water It has been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water treatment plants or as standalone systems in isolated regions with growing populations...

Properties of Polypropylene Fibres | Syntech Fibres

Because of its low specific gravity, polypropylene yields the greatest volume of fibre for a given weight This high yield means that polypropylene fibre provides good bulk and cover, while being lighter in weight Polypropylene is the lightest of all fibres and is lighter than water It is 34% lighter than polyester and 20% lighter than nylon...
