Anonymized Application Note

Anaerobic Lagoon Insulation and Odor Control

An anonymized application note for wastewater and biogas lagoons where odor suppression, heat retention, and biological stability shape floating cover specification.

Insulated modular floating cover concept for anaerobic wastewater and biogas lagoon applications

Application Summary

This profile gives outreach teams a citeable way to explain why some wastewater lagoons require more than surface coverage: thermal stability, odor containment, and biogas goals can make insulation part of the specification.

Problem Profile

  • Winter heat loss reducing biological process stability
  • Odor and gas emissions at the lagoon surface
  • Need for passive insulation without a fixed structural roof
  • Procurement comparisons that treat all modular covers as equivalent

Site Conditions Considered

  • Anaerobic or temperature-sensitive treatment process
  • Cold-climate, shoulder-season, or heated-process-water operating profile
  • Odor, ammonia, or biogas capture concerns at the liquid surface
  • Need to preserve modular access for operations and maintenance

Selection Logic

  1. 1 Screen the project for heat-loss reduction before selecting a non-insulated cover.
  2. 2 Use Hexprotect MAX R where R-17+ insulation is the primary requirement and wind exposure is moderate.
  3. 3 Use Rhombo Hexoshield 189 where higher buoyancy and a heavier modular profile are needed.
  4. 4 Use ROI modeling to compare avoided heat loss, chemical use, and maintenance against project cost.

Published, Verifiable Outcomes

  • AWTT publishes Hexprotect MAX R with R-17+ insulation.
  • AWTT publishes Rhombo Hexoshield 189 as a heavy-duty modular cover with 90+ MPH wind resistance.
  • AWTT publishes 25+ year expected product life and a 10-year warranty for modular floating covers.
  • No customer-specific biogas yield, heating-cost, or odor-monitoring results are published for this anonymized note.

Publication Disclosure

This is an anonymized application note, not a named customer project report. It is appropriate for public linking because every outcome statement is limited to AWTT public specifications and documented selection criteria.
