Fish shrimp pond geomembrane liner
Geomembrane liner is a material widely used for water seepage prevention, mainly used in fish or shrimp ponds, reservoirs, artificial lakes, wastewater treatment pools and other projects. It is usually made of high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC) and other materials, with excellent anti-seepage performance, corrosion resistance and aging resistance. In order to adapt to the environmental characteristics of long-term exposure to sunlight, the pond aquaculture geomembrane liner of Haoyang Environmental Co., Ltd. also adds antioxidant and anti-ultraviolet masterbatch to the geomembrane, which can enhance the service life of the geomembrane.
1.Geomembrane as a liner for fish and shrimp ponds has the following advantages:
1.1. Improve water quality management
Geomembrane can effectively prevent pond water leakage, keep the water volume stable, and help maintain good water quality. This is very important for fish farming, because a stable water environment is conducive to the healthy growth of fish.
1.2. Prevent pollution
Geomembrane can prevent pollutants in external soil and groundwater from entering the pond and keep the pond water pure. At the same time, it can also prevent waste and harmful substances in the fish pond from seeping into the groundwater and protect the environment.
1.3. Control water depth and temperature
Geomembrane can help the fish pond maintain appropriate water depth and temperature, which helps to create a suitable growth environment. Due to the anti-seepage characteristics of geomembrane, the water depth of the pond can be better controlled, which is conducive to the habitat and reproduction of fish.
1.4. Increase production
Because geomembrane can provide a more stable and clean water environment, it helps the healthy growth of fish and reduces the incidence of diseases, thereby increasing fish production.
1.5. Reduce maintenance costs
Geomembrane is durable and corrosion-resistant, with a long service life, reducing the maintenance and repair costs of the pond. In addition, by preventing water leakage, the waste of water resources and the cost of water replenishment are reduced.
2.Installation and maintenance
2.1.Installation steps
2.1.1.Pond preparation: Before laying the geomembrane, you first need to level the bottom and slope of the pond, and remove sharp objects such as stones and tree roots to prevent puncturing the geomembrane.
2.1.2.Laying geomembrane: Unfold and lay the geomembrane on the bottom and slope of the pond to ensure that it is flat and wrinkle-free. There should be a certain overlap between each geomembrane to ensure the firmness of the joints.
2.1.3.Welding seams: Use hot air welding or extrusion welding to treat the joints of the geomembrane to ensure that the welding is firm and there are no leaks.
2.1.4Laying a protective layer: A protective layer such as geotextile or sand and gravel layer can be laid on top of the geomembrane to prevent mechanical damage and ultraviolet aging.
2.2Maintenance
2.2.1.Regular inspection: Regularly check the condition of the geomembrane, especially the welding seams and vulnerable areas, and repair them in time if damage is found.
2.2.2.Cleaning and protection: Keep the pond clean, prevent large mechanical equipment from directly contacting the geomembrane, and avoid scratches on the geomembrane by sharp objects.
2.2.3.Replacement and repair: According to the service life and damage of the geomembrane, local repair or replacement should be carried out when necessary to ensure its anti-seepage effect.
3.How to balance the cost of geomembranes for pond farming？
The use of geomembranes in pond fish farming can not only effectively improve water quality and environment, but also increase fish production and farming benefits. Correct installation and maintenance are the key to ensuring the long-term and effective use of geomembranes.
In practical applications, how to balance the cost of geomembranes for pond farming?
3.1. Appropriate geomembrane materials and specifications should be selected according to specific farming needs.
3.2. Geomembranes of different thicknesses should be selected according to the area and depth of the farming pond to balance the investment cost;
3.3. Whether to select new materials or partially add recycled materials should be considered according to the length of the use cycle of the farming pond, considering the balance between investment cost and payback period.
3.4.
