COUPLED ANAEROBIC DIGESTER: WETLAND SYSTEM FOR DAIRY WASTE AND STORMWATER TREATMENT WITH BIOGAS PRODUCTION
Impact/Purpose:
The objective of the project is to evaluate the designs of coupled anaerobic digester
and treatment wetland systems to develop low-cost wastewater treatment systems for dairy
wastewaters and stormwater with a return on investment through energy production.
Description:
By coupling wastewater treatment and biogas production, the proposed design
will increase sustainability by (i) decreasing pollution of waters, fields, and ecosystems, and (ii)
providing a return-on-investment for wastewater and stormwater treatment, (iii) decreasing costs
of milk production, and (iv) decreasing energy consumption and greenhouse gas production.
Outcomes include laboratory assessments of variables affecting system function, independent
models for the digester and wetlands, and a transportable system model for site-specific design.
Through outreach, the project will educate students and dairy producers on incorporation of
environmental and economic sustainability in design.

Project Information:
Approach
:Design will combine laboratory experimentation and reactor design to develop a
system model for synthesis and optimization of three designs: separate digester and wetlands, a
coupled digester:wetland system with land application of effluent, and a coupled system with
surface discharge of effluent. Designs will be evaluated from both economic and environmental
perspectives and feedback from faculty, industry professionals, and dairy producers will be
incorporated into design recommendations for a MSU dairy.
