WP-2: G B PANT UNIVERSITY OF AGRICULTURE AND TECHNOLOGY (GBPUAT), PANTNAGAR

Main objective:

• To develop a demonstration model for remediation of wastewater through stabilization pond based floating raft and evaluation of immobilized bacterial cells for enhancing its efficiency.

• To assess dendro-remediation potential for polishing and reuse of wastewater by bioenergy plantation and to subtle operational criteria for zero discharge.

• To investigate the nutrient/ pollutant uptake and removal dynamics in natural treatment system, estimation of carbon sequestration and biomass production of bio-energy trees under fertigation and evaluation of economic attributes.

• To determine pollutant contamination fate and exposure pathway in developed model.

​​

Methodology:

• Demonstration of on-site experiment model in 1 hectare land for remediation of domestic wastewater by natural system of stabilization pond combined with floating raft immobilized bacterial cells and dendro-remediation.

• Polishing of treated wastewater for reuse through fertigation for zero discharge and energy plantation biomass growth by dendro-remediation system.

• Sampling and analysis of water, soil and microbial parameters on monthly/ seasonal basis for determining pollutant loading and its removal efficiency.

• Leachate study for soil and ground water contamination and risk assessment.

• Estimation of energy trees biomass growth, carbon stock calculation in soil and plant for carbon sequestration.

• Design suitable and efficient natural treatment system for domestic wastewater reclamation and reuse.​

​

Deliverables:

• Reclamation & re-use of wastewater, develop guidelines for design & standardization of natural treatment system for water security & Environmental protection.

• Bioenergy plantation for biomass, enhanced carbon sequestration and better economic attributes for benefits of the society.

• Proposed study would be a complimentary effort for the Namami Gange, Clean India and Tree credit campaign launched by Govt. of India & can be used by Govt./ NGOs / Industries/ Municipal bodies/ Researchers for water resource management.​
