Integrated Wetland Technology

Product Description

The Integrated Wetland Technology is a primary, secondary, and tertiary natural engineered wastewater treatment system, delivered by Emergy Enviro Pvt. Ltd. The design replicates the natural process involved in wetland vegetation, soils, and microbial assemblages to assist the treatment of wastewater. Treated water from the system can be used for irrigation, gardening, and toilet flushing.

Design Specifications

The Integrated Wetland Technology is comprised of two stages which acts as primary and secondary wastewater treatment, with optional tertiary treatment. The first section is the Primary Solid Removal Tank (PSRT), which acts as the primary clarifier. This consists of a settler, digester and aeration unit to remove TSS (70 to 80%) and BOD (45 to 55%). Vent pipes are equipped to remove odour. The second section is a planted bed which consists of gravel media and various wetland plants such as Colocasia Esculenta, Canna Indica, Cyperus alternifolus. This stage removes BOD (85 to 95%). The two-stage management system cleans the gravel media without removal, prevents choking in the media and prevents overflow. Treated sewage from the planted bed can be subjected to tertiary treatment such as a pressure sand filter, activated carbon unit and disinfection unit.

Manufacturer Specified Performance Parameters

The manufacturer cites minimal operational energy requirement, no technical expertise required for operation, minimal maintenance costs, modular design, methane capture and reduced environmental impacts as performance targets.

Vetted Performance Status

Integrated Wetland Technology has been tested by the Tennessee Valley Authority for the removal of COD (84%+), ammonia nitrogen (93%) and phosphorus (>90%).

Safety

Wastewater must be handled, treated and disposed of in accordance with hygiene and CPCB environmental standards.

Complementary Technical Systems

Treated wastewater can be discharged for secondary uses such as irrigation and toilet flushing purposes.
