Why Use Floating Covers?

October 12, 2010

Floating Cover Systems

Floating Cover Systems are successfully used in several commercial and municipal applications.  Some examples include:

  • evaporation and algae growth prevention
  • potable water protection from pollution and contamination
  • odor and emission control
  • biogas recovery for power generation or flaring
  • protection of birds and waterfowl from contact with hazardous liquids
  • remediation contamination

Why Use Floating Covers?

The best engineered floating cover systems cost 75% to 85% less than most every acceptable rigid roof structure.  A single floating cover can exceed over a million square feet / 93,000 square meters of surface area and be viable.  Saving of natural resources is another large factor that should be considered.

Floating cover systems prevent water loss due to evaporation; greatly reduce algae growth and treatment chemical demand resulting in improved water quality.  They also provide barriers against contamination by dead animals, airborne particles such as pollen and bird droppings.

In potable water contamination applications, another advantage is treatment chemical cost reduction and positive health impact as considerably less chlorine is required in covered reservoirs.  Using less chlorine in potable water enhances safety by reduced production of trihalomethane (TTHM) (a methane-derived compound that contains three halogen atoms, e.g. chloroform, formed especially during the chlorination of drinking water) type compounds like chloroform that result from the combining of organic substances with chlorine.

Floating Cover Systems have been used for about 35 years.  Service life’s of 20 years or more have been recorded in potable water applications.  Gas collecting floating cover systems can be expected to perform for about ten years.

Floating Cover Systems For Potable Water

Floating covers prevent losses through evaporation.  Odor and taste free, they help protect potable water supplies by minimizing reservoir contamination from dust and dirt, leaves, insects, animals, etc.  Literally tons of such debris can collect at the bottom of uncovered reservoirs.  This can actually trap chlorine, and make it difficult, if not impossible, to maintain a sufficient amount in the water itself.

Floating covers also exclude sunlight.  This reduces problems with algae growth and chlorine depletion.  Floating cover systems are customized for each client’s lagoon or tank size and shape.

The American Water Works Association and many states recommend covering all reservoirs containing potable water that will be delivered directly to customers.  Some states even require it.

Floating cover applications:

  • any type of gas collection from water basin
  • keep rain & snowmelt water separate from wastewater under the cover
