SWRO Chennai Case Study

Abstract The water need of Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) to fully serve the said area by 2026 is 2248 million liters per day (MLD) whereas the maximum potential from surface water, ground water and sea water desalination (SWRO of 200 MLD) is only 1954 MLD. The cost of SWRO water is about Rs 55 per Kiloliter (Kl) whereas the tariff for public is just about Rs. 5 per Kl by Government subsidy which cannot be sustained for long. Out of 1810 MLD, 837 MLD is from…

Grey Water Management

INTRODUCTION Grey water refers to the wastewater generated from domestic activities, including water from bathrooms, kitchens, and laundry. While it is typically contaminated, it is not as hazardous as black water (from toilets). In areas with high population density, such as the Lower Ganges Basin and other river basins, managing grey water presents a significant challenge. This article discusses the natural purification and settlement processes of grey water that exist within local ecosystems. The primary contaminants found in grey water include: Detergents and Surfactants: From laundry and dishwashing soaps, these…

Regenerated Resins

As populations surge and industries expand, the demand for clean water is reaching unprecedented levels. However, the conventional approach in the industry, relying on single-use ion exchange resins, carries a substantial environmental cost. In the current linear model, significant quantities of virgin resources are consumed, greenhouse gases are emitted, and landfills bear the weight of discarded resins. However, with resin regeneration, there is potential for a more sustainable way forward. Resins revitalized – a greener horizon Resin regeneration is the process of rejuvenating exhausted water treatment resins, extending their lifespan,…
