5 types of floating covers

^{Here we tell you about the 5 most commonly used floating covers:}

1. Geomembrane Covers

Geomembranes are sheets made of synthetic materials, such as high-density polyethylene (HDPE) that float on water and are very common because they are inexpensive and easy to install.

‍

Advantages of Geomembrane Cover:

/ Economical: They are relatively cheap to produce and install.

/ Waterproof: They help reduce water loss through evaporation.

/ Easy to install and maintain: They are quick to install and do not require complicated equipment when covering small surfaces.

/ Durable: They offer good protection from sun and chemical exposure.

‍

Disadvantages of Geomembrane Cover:

/ Limited durability: Although they are durable, they can deteriorate over time due to constant sun exposure and weather conditions.

/ Visual impact: Some people may not prefer their appearance since they cover the surface of the water.

/ Maintenance required: They may need occasional repairs if damaged, usually by wind or rain.

2. Mesh covers:

This type of cover is not installed in direct contact with the water but rather over the water, using tensioned wires for support. These covers are usually made of plastic materials such as polyethylene (PE), polypropylene (PP) or similar materials. Unlike geomembranes, mesh covers are permeable, meaning they allow air and water to circulate beneath them.

‍

Advantages of mesh covers:

/ Reduced evaporation: By partially blocking the sun, the mesh helps reduce water evaporation.

/ Algae protection: It limits the amount of light that reaches the water, which helps prevent algae growth, improving water quality.

/ Cost-effectiveness: Mesh covers are usually cheaper than other types of thicker floating covers, such as geomembranes, and do not require complex installation.

‍

Disadvantages of floating mesh cover:

/ Partial protection: Although the mesh offers shading and reduces evaporation, it does not provide complete protection from the sun, so it is not as effective as geomembranes or floating elements in preventing water loss or algae growth.

/ Requires regular maintenance: Although mesh is durable, it can accumulate debris such as leaves or dirt, so it is necessary to clean it periodically to maintain its effectiveness.

/ Durability: They usually last between 3 and 5 years. They are affected by sunlight, rain and wind.

3. Modular floating elements

Modular floating covers are made up of elements that are autonomous and floating, but together they form a unified structure.

‍

Advantages of floating modular element covers:

/ Flexibility: Floating elements can be adapted to any geometric shape, size and water level variations.

/ Easy to transport and install: They are light and easy to store and install.

/ Durability: They usually last more than 25 years thanks to UV and antioxidant additives

/ Maintenance: They do not require maintenance

/ Efficiency: They have a high efficiency

‍

Disadvantages of floating modular element covers:

/ High initial cost: Although they are modular and easy to install, the initial cost of the modules can be higher compared to other types of covers.

4. Nature-based floating covers (duckweed)

Nature-based floating covers are systems that mimic natural ecosystems, such as duckweed. Duckweed is a floating plant that grows in bodies of water, forming a layer on the surface that helps reduce evaporation and algae proliferation.

‍

Advantages of nature-based floating covers:

/ Sustainability: These covers take advantage of the properties of plants to perform their function, making them green and environmentally friendly.

/ Algae reduction: Floating plants block sunlight, reducing algae blooms and improving water quality.

‍

Disadvantages of nature-based floating covers:

/ Requires maintenance: Plants can grow out of control and require periodic pruning.

/ Visual impact: Some people may find floating plants create an unsightly "blanket" on the water.

/ Not suitable for all bodies of water: This type of cover is not suitable for bodies of water with a lot of activity.

5. Photovoltaic floating covers

Photovoltaic floating covers are floating platforms on bodies of water that are covered by solar panels. These panels convert sunlight into electrical energy, and the water beneath them helps keep the panels at a lower temperature, improving their efficiency.

‍

Advantages of floating photovoltaic covers

/ Clean energy generation: Solar panels produce renewable electricity, which helps reduce dependence on non-renewable energy sources.

/ Improved efficiency of solar panels: Water cools solar panels, which improves their performance.

/ Utilization of unused spaces: They are installed over bodies of water that are not used for other purposes, maximizing the use of space.

‍

Disadvantages of floating photovoltaic covers

/ High initial cost: Installing floating photovoltaic systems requires a significant investment.

/ Dependence on the weather: The efficiency of the panels depends on the amount of sun available, which can vary depending on the geographic location.

/ Technical maintenance: Solar panels require technical maintenance, such as cleaning and periodic checks, which can be expensive and laborious.

‍

In conclusion, floating covers offer a versatile and sustainable solution for protecting the water. By understanding the different types and their specific advantages and disadvantages, you can select the most suitable option for your needs. Whether it's to conserve water, improve water quality, or generate clean energy, floating covers provide a valuable tool for managing and protecting our water resources.
