Integrated resource recovery at East Calcutta wetland: How safe is these?

2

East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compared to those grown in south eastern parts of West Bengal (Midnapur).

Removal of nitrogen in constructed wetlands to prevent eutrophication

2

Nitrogen is an important nutrient in domestic and industrial wastewater and its elevated concentration in the wetland promotes explosive growth of algae. The decomposition of the algae leads to an excessive growth of bacteria, utilizing and dissolved oxygen from water. This process of rapid algal growth leading to oxygen-starved waters is known as eutrophication.
