Attapulgite clay‚ zeolites and polymer filtration; 3- Nanocatalysts; 4- Magnetic nanoparticles; 5- Nanosensors for the detection of contaminants. Nanofiltration membranes Researchers are using nanomaterials ( e.g carbon nanotubes‚ alumina fibres) to build structures that have controlled shapes‚ density and dimensions for specific filtration applications. For instance‚ researchers have developed and tested cylindrical membranes with pores tiny enough to filter out the smallest organisms.

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two
