Aquifers around the world are depleting and being polluted due to multiple problems of contamination of ground or surface water by Algal Blooms, industries, heavy metals. Major class of contamination is industries dyes as they are highly reactive, nonbiodegradable, toxic and mutagenic in nature. Therefore, Waste Water Treatment treats the dye effluents from industries and is a mandatory part.

The traditional treatment technologies like oxidation, activated carbon, activated sludge, nanofiltration and reverse osmosis membranes are not much effective to treat such complicated pollutants present in aquifers. There has been a need to develop alternative method to resolve water related problems.

Nanotechnology has been considered effective in solving water problems because nanomaterials are outstanding adsorbents, catalysts, sensors due to their large surface area and high reactivity. The nanomaterials as adsorbent can remove the pollutant by applying mild Gravitational and Magnetic forces. So, metal nanomaterials are the versatile materials which can be used in many applications such as environmental remediation and water treatment.

Apart from nanomaterials, conducting polymers possess alternating double and single bonds. Conducting polymers like Polyaniline is the most investigated due to its good desirable electrochemistry, processability and large surface area which traps the reactive segments.

In this paper, the combination of Metal nanoparticles and conducting polymers has revealed great potentials in range of application fields, in which the metal shows excellent optical and catalytic performances whereas polymers exhibit unique electronic properties. The combination of two such as Silver Polyaniline and Gold Polyaniline have been showing great catalytic activity in various applications.

Furthermore, in this paper Aniline oligomers are synthesized to furnish the superiority of well- defined molecular structures, chain length and groups. Tetraaniline is one of the oligomers of polyaniline which shows similar properties of polyaniline. On the whole paper, it is intended to say importance of Tetraaniline nanocomposites towards the water treatment applications.
