Wastewater is always going to remain issue until new technologies does not involve in it. The point of treating wastewater by conventional system is that it’s easy and costly but is it sustainable? The coal is used to generate electricity that runs the motor that treats the wastewater but what is new in that, we know that sustainability is the only solution this days. As it has been estimated that most of the developing countries will run out of water by 2050 and scientist will have to encourage in finding the new technologies and that is possible only when we use what we have rather than invest in impossible. Constructed wetlands systems as we know uses land that is available and plants of specific types and season wise for specific wastewater to treat it. Firstly they have been used for urban and domestic wastewater treatment, but in the last two decades, the applications for industrial wastewater treatment increased due to the evolution of the technology and the experimented research on the field. Nowadays, Constructed wetlands have been applied to the treatment of different kind of effluents as such as refinery and petrochemical industry effluents, food industry effluents including dairy waste, waste from meat and flash, fruit and vegetables processing industries, distillery and winery effluents, pulp and paper, textile, tannery, aquaculture, steel and mixed industrial effluents. Constructed wetlands and its types are important factor as different wastewater is treated differently for removal of nutrients, organic matter, suspended solids and that is to be discussed in briefly here.

Key Words : Industrial wastewater, constructed wetlands, Nutrients removal, COD, TDS.
