Modular basin cover COVEX®

floatingplasticfor wastewater

Covex® Floating Cover is a modular system of plastic hexagons designed to cover liquid surfaces and provide evaporation control, algae and odor suppression, insulation and wildlife protection.

Key benefits

• Evaporation reduction: up to 97% reduction in water loss.
• Algae and biofilm reduction: ~95% reduction by blocking sunlight and preventing photosynthesis.
• Odor reduction: over 90% reduction of odours from covered liquids.
• Freeze retardant / insulating: insulation properties delay freezing by many hours.
• Significant heat loss reduction: reduces heat loss and energy consumption for heated liquids.
• Water & wildlife protection: keeps birds and other wildlife away from the liquid to avoid contamination; helps prevent mosquito formation.

How it works

• Modular hexagonal units interlock and — when installed across the surface — cover about 98% of the liquid surface, creating a continuous barrier.
• Hexagons are water-ballasted (filled with water) to lower their centre of gravity and improve stability and wind resistance.
• Coverage is immediate and the system is maintenance-free; no chemicals or running equipment are required to achieve the biological/odor benefits.

Applications & advantages

• Used across agriculture, mining, wastewater treatment and other industries.
• Manufactured using recycled plastic and designed to use the least plastic possible; produced using renewable energy sources and conceived as a circular-economy product.
• Proven efficiencies supported by universities and technical entities in thermodynamics and fluid dynamics.
• Warranty & lifespan: 10-year warranty against manufacturing defects; expected lifespan beyond 25 years.
