Municipal Wastewater Lagoon Odor and Algae Control

An anonymized wastewater application note for specifying Hexprotect AQUA on municipal lagoons that need algae suppression, odor reduction, and wind-resistant surface coverage.

Hexprotect AQUA modular floating covers on a wastewater lagoon for algae and odor control

Application Summary

This profile documents a common municipal lagoon specification pattern: operators need to reduce exposed water surface, suppress algae growth, limit odor release, and avoid wind displacement without adding mechanical anchoring or permanent structures.

Problem Profile

  • Seasonal algae growth increasing treatment burden and discharge-risk conversations
  • Hydrogen sulfide and ammonia odor concerns near lagoon perimeters
  • Open-water exposure where lightweight covers can drift or bunch under wind
  • Need for access to the liquid surface without a fixed geomembrane cover system

Site Conditions Considered

  • Open lagoon geometry with variable operating levels
  • Municipal or industrial wastewater chemistry compatible with HDPE cover materials
  • Operator preference for passive installation and low routine maintenance
  • Surface-coverage requirement higher than standard ball covers can provide

Selection Logic

  1. 1 Specify up to 99% surface coverage where sunlight blockage and liquid-air interface reduction are the primary control mechanisms.
  2. 2 Use water-ballasted modular units where wind exposure is a design concern.
  3. 3 Keep the cover modular so operators can remove localized sections for inspection, sampling, aeration equipment, or repairs.
  4. 4 Reference AWTT technical data for product density, wind resistance, operating temperature, warranty, and expected service life.

Published, Verifiable Outcomes

  • Hexprotect AQUA is published by AWTT as a water-ballasted hexagonal cover with up to 99% surface coverage.
  • AWTT publishes a 130+ MPH wind-resistance rating for Hexprotect AQUA.
  • AWTT product pages and technical data publish 25+ year expected life and a 10-year product warranty for modular floating covers.
  • No customer-specific before/after odor, TSS, BOD, or complaint-rate measurements are published for this anonymized note.
