Hollow Plastic Ball Covers for Wastewater Ponds & Lagoons

The challenge

• Odor and H₂S complaints from neighbors and regulators
• VOC emissions and the compliance pressure they create
• Algae and cyanobacteria blooms in open basins
• Costly or short-lived mechanical and membrane covers

How Armor Ball® helps

A poured-on 91% layer of Armor Ball® acts as a physical barrier over the liquid surface, suppressing the odor, H₂S, and VOC release that drives nuisance complaints and compliance pressure. At the same time, the opaque HDPE blocks the sunlight that feeds algae and cyanobacteria — so one cover controls two problems at once.

The balls are inert across pH 2–13 and pour directly onto the existing surface with no draining, anchoring, or liner penetration, so the basin stays in service during install. They move aside for aerators and equipment, then re-cover automatically, and need no maintenance over a 25+ year design life.

What to look for when covering a wastewater treatment surface

• Chemical compatibility: Wastewater chemistry varies; request material certifications and an SDS to confirm Armor Ball® HDPE suits your specific liquid across its pH range.
• Equipment access: Where aerators, mixers, or decanters need access, the free-floating balls push aside and re-cover — no panels to cut or re-fit.
• Coverage quantity: Plan on about 10 balls per ft² (108/m²); use the coverage calculator to size your basin before requesting a quote.
