Slide2IntroductionHigh demand of water due to increase in population
High amount of wastewater is generated
The wastewater contains micro-organisms, organics, metals and toxicants
Metals (copper here) are highly carcinogenic
Metals cannot be decomposed or bio-degraded
They have to be removed during treatment
Slide3Removal of copperPrecipitation
Flotation
Ion Exchange
Electrocoagulation
Adsorption
Adsorption is widely used for the removal of metals because of its simplicity and effective cost
Slide4Nanoparticles
The most common adsorbent (nowadays) are nanoparticles
Nanoparticles are particles with size less than 100nm
The advantages of using nanoparticles as adsorbent are-
H
igh
surface
area
in low volume
Magnetic characteristics
Low cost
Effective contaminant removal even at low
concentrations
Less waste generation
post-treatment

Reaction by-products
Future research
Non corrosive nanoparticles should be more used
Reaction by-products should be
minimised
