Unit I
INTRODUCTION TO WETLAND TREATMENT SYSTEM Definition and concept of wetland – types of wetland. Wetland – ecology, flora and fauna, ecological aspects, human health and wetland, onsite applications. introduction to constructed wetland-types- free water surface, subsurface wetland-horizontal and vertical flowwastewaters and their application in wetland – constructed wetland plants-media – in constructed wetland.
Unit II
CONSTRUCTED WETLAND AND REMOVAL MECHANISMS Site identification- construction and design of constructed wetland, startup, operation and maintenance of wetland system-wetland hydrology- hydraulics. Treatment of domestic wastewater and its performance, mechanisms of pollutant removal- suspended solids, organic matter, nitrogen, phosphorus, pathogen and other contaminants. Reuse of treated wastewater and its applications- limitation of constructed wetland system.

Unit IV
DESIGN OF WASTEWATER POND SYSTEMS Introduction- facultative -partial -mix aerated- ponds -complete -mix aerated pond systems -anaerobic ponds -nitrogen removal in lagoons. Modified high -performance aerated pond systems for nitrification and denitrification – nitrogen removal in ponds coupled with wetlands and gravel bed nitrification filters -Control of algae and design of settling basins. Hydraulic control of ponds – removal of phosphorous -removal of pharmaceuticals and personal care products and antibiotic resistant genes.
Unit V
SLUDGE MANAGEMENT AND TREATMENT Sludge quantity and characteristics – stabilization and dewatering -sludge freezing -reed beds – Vermi stabilization -comparison of bed type operations -composting land application and surface disposal of bio solids onsite wastewater systems -effluent disposal and reuse. Sludge quantity and characteristics-stabilization and dewatering-sludge freezing reed beds-Vermi stabilization- Comparison of bed-type operations-composting land application and surface disposal of biosolids- on-site wastewater systems- effluent disposal and reuse.
Course Outcomes:
On completion of the course, the student is expected to be able to
- Explain the various aspects of wetland system, its function and its application in the treatment of wastewaters
- Apply the knowledge of science and engineering fundamentals to know the types of wetlands, construction and operation of wetlands, wetland hydraulics and design of wetland and its performance Understand the process of treatment of domestic waste in the removal of solids, organic matter, phosphate, nitrogen, pathogens and its reuse
- Understand the process of treatment of industrial wastewater in the removal of solids, organic matter, phosphate, nitrogen, heavy metals, phenolics and feasibility for reuse
- Understand the various pond system available for wastewater treatment. design of pond system -removal mechanism
- Manage and dispose the sludge naturally and economically.
