Not Just a Cover — A Flexible Membrane System for Wastewater Control

A wastewater tank cover membrane is selected to solve practical plant problems: odor emission, algae growth, rainwater intrusion, wind-blown debris, evaporation loss, process temperature fluctuation and difficult access for inspection or maintenance.

DERFLEX focuses on the membrane material layer behind the cover system. Our PVC coated polyester membrane can be used by cover fabricators, wastewater contractors, EPC companies and OEM system builders to create tank covers, clarifier covers, floating covers, retractable covers and custom prefabricated membrane panels.

Blocks sunlight to help reduce algae growth in clarifiers, channels and treatment tanks.
Helps contain odor emissions for connection to ventilation, filters or odor-control systems.
Protects wastewater tanks from debris, rainfall, wind exposure and wildlife access.
Supports custom tank geometry, field welding and prefabricated cover production.

Custom Membrane Covers for New & Existing Tanks

DERFLEX membrane materials can be specified for concrete tanks, steel tanks, lagoons, clarifiers, equalization basins and process water facilities.

What Is It?

What Is a Wastewater Tank Cover Membrane?

A wastewater tank cover membrane is a reinforced flexible sheet material used to cover open wastewater tanks, basins, clarifiers, sludge storage tanks, lagoons or process water structures.

Odor Control

The cover membrane limits direct release of odorous gases and can support off-gas collection for scrubbers, biofilters or activated carbon systems.

Sunlight & Algae Control

By reducing sunlight exposure to the water surface, the membrane helps control algae growth and improves treatment plant cleanliness.

Environmental Protection

The membrane reduces debris, rainfall, wildlife access and unwanted surface exposure, supporting better plant operation and community protection.

Cover Types

Membrane Material for Multiple Wastewater Cover Designs

Different wastewater plants require different cover structures. DERFLEX supplies membrane materials that can be integrated into several cover system designs.

Option 01

Tensioned Tank Cover Membrane

A membrane stretched across a structural frame, aluminum support system or tank perimeter, often used for odor control and easy maintenance access.

Good for clarifiers and tanks
Clean surface appearance
Custom openings and hatches
Suitable for new or retrofit projects

Option 02

Floating Wastewater Cover

A membrane cover that floats on the liquid surface to reduce odor, evaporation, sunlight and vapor release in lagoons or storage basins.

Useful for lagoons and ponds
Helps reduce evaporative loss
Can support gas collection design
Custom perimeter anchoring

Option 03

Retractable / Access Cover Membrane

A flexible membrane used in covers where operators need quick access for sampling, equipment inspection, cleaning or maintenance.

Easy access design support
Roll-up or sectional cover use
Supports hatches and ports
Better operator convenience
