Tertiary Treatment Reverse Osmosis (TTRO)

Tertiary Treatment Reverse Osmosis (TTRO) - Case study

Tertiary treated Reverse Osmosis (TTRO) Plant Projects for wastewater reuse.
Project Name:  Feasibility Study for the Formation of Treated Wastewater Reuse Grid & Preparation treated water reuse policy for the state of Tamilnadu
Project location within the Country: All over the districts within state of Tamilnadu  
Name of the Client : PDGF – TNUIFSL 
Project Period:2018-19
Description of actual services provided:

The demand for water is increasing due to ever-increasing population, urbanization and industrialization. But the water potential is constant. The water potential available in Tamil Nadu both groundwater and surface water is about 47,680 MCM, whereas the demand of water for various sectors as per Tamil Nadu state action plan for climate change is 49,773, 52,891, and 55,919 MCM for the years 2011, 2020, and 2048 respectively. To meet the demand-supply gap, the Government of Tamil Nadu – through Tamilnadu Water Investment Company (TWIC) – has prepared a feasibility report for the formation of treated wastewater reuse grid from the Sewage Treatment Plants (STPs) to the industries all over Tamil Nadu. As part of study TWIC has done demand assessment across the state for reuse water and has suggested to form 52 grids. Based on the wastewater generation and water demand estimated, the total grids were again sub grouped into Short term (10 Nos), Mid-term (11 Nos) & Long term ( 31 nos).  Based on the study, The State Government of Tamil Nadu has also released a “Treated Wastewater Reuse Policy”.
