How thick is the appropriate geomembrane for fish pond impermeability?

Fish pond impermeable geomembranes play a major role in avoiding direct contact between fish and soil and water pollution. It prevents waste from accumulating in the soil as well as harmful chemicals such as ammonia, hydrogen sulfide, acids, iron and other potentially harmful compounds from entering the pond, thus reducing the risk of disease and effectively protecting and promoting the growth of fish. Impermeable membranes for fish ponds provide a smooth surface for easy removal of pond waste, facilitate fishing, and protect pond slopes from erosion.

Is HDPE geomembrane suitable for aquaculture? Can geomembranes be used for new fish ponds or shrimp ponds? With these questions, let's read the following carefully, and I believe you will find the answers you want in it! In aquaculture, the more important thing is the condition of the bottom of the pond, because it will directly affect the water quality, which in turn affects the breeding. Do not use a single water quality indicators to reflect the good or bad aquaculture environment and ignore the importance of the substrate.

At present, some ponds in coastal areas using cement or the use of geomembranes laid out, geomembranes are flexible materials to prevent water seepage and are widely used in aquaculture; this construction method is separated from the original substrate, high pond mode occupies a certain number of ponds with geomembrane substrate, because the membrane will be separated from the natural substrate of fish, water quality will not be affected by the bottom of the pond, increasing the chances of pond site selection. It is indeed a proven method if geomembranes are laid in ponds with high terrain, poor substrate conditions and more serious seepage to prevent seepage culture.

The use of geomembranes for substrate culture requires attention to water quality control through scientific water changes, regular drainage and reasonable use of oxygenators and other management measures; in addition, because the geomembrane substrate does not have a composite silt, it does not breed various harmful organisms, so the use of fish medicine is also more effective.

Through the above content, we can know that geomembranes are suitable for fish ponds, shrimp ponds culture; and in actual production, no matter which way to use culture, the eutrophication trend of the water body is only a matter of time, so in the process of culture, take relevant management measures to achieve better benefits.

Aquaculture special impermeable cloth geomembrane selection specifications thickness between 0.3-1.0mm, farmers can choose according to their own aquaculture products, general aquaculture fish and shrimp, loach, eels, then choose about 0.5mm thickness of impermeable film can be. The impermeable film is made of polyethylene virgin resin with 97.5% high-density polyethylene as the main component and about 2.5% carbon black, anti-aging agent, anti-oxidant, UV absorber, stabilizer and other auxiliary materials. At present, Lianxiang Geosynthetics adopts the international advanced fully automatic geotechnical production equipment and is made by three-layer co-extrusion technology. All products can meet the GB, GRI standards and ASTM test standards, complete specifications, glossy rough surface thickness 0.25mm-3.0mm, width 2m-8m, to meet the environmental protection, sanitation, water conservancy, construction, municipal engineering, gardening, landscape, petrochemical, mining, salt, agriculture, aquaculture industry application requirements.
