HDPE vs EPDM Pond Liner, Which One Is Better for Shrimp Ponds

In aquaculture shrimp farming industry, pond liner has become a essential option considering its anti seepage and environmental functions. It values a lot to choose a best pond liner material that in accordance with the specific requirements of shrimp pond management in aquaculture as the aeration feeding etc. So which one is better of HDPE vs EPDM Pond Liner for shrimp pond? EPDM liners may be suitable for certain applications such as small fabricated pond while HDPE liners are commonly preferred in aquaculture farming project due to the difference in impermeability, puncture resistance, lifespan, installation, material size etc.

GEOSINCERE is the leading geosynthetics and geomembrane pond liner manufacturer and supplier, our smooth geomemrbanes include smooth HDPE geomembrane liner, EPDM pond liner, PVC pond liner, etc. Before selecting between HDPE vs EPDM Pond Liner for aquaculture shrimp ponds, we need to consider the following factors such as water retention, chemical exposure, ease of installation, and long-term performance.

1. HDPE vs EPDM Pond Liner, Why HDPE Pond Liner Is Better for Shrimp Ponds?

Ethylene Propylene Diene Monomer (EPDM) liners are a kind of synthetic rubber material that can be resistant to UV radiation, ozone, and weathering etc. EPDM liners have certain advantages, but HDPE pond liner is the better choice for shrimp ponds compared with EPDM pond liner.

1.1 HDPE vs EPDM Pond Liner, HDPE Is More impermeable Than EPDM

EPDM liners are not as impermeable as High-Density Polyethylene (HDPE) geomembrane liner. GEOSINCERE HDPE pond liner is a globally popular material in Shrimp ponds which with low permeability to prevent water seepage, ensure water retention, and maintain proper water levels. This is all its benefits we can get in the aquaculture industry.

1.2 HDPE Pond liner generally Has Better Puncture Resistance Compared with EPDM Pond Liner

Shrimp ponds need to be subjected to various activities from people, including the movement of equipment such as aerators, drainage pipe, welding machine and also maintenance procedures, and exposure to sharp objects. HDPE liners generally have better puncture resistance compared to EPDM liners, which can reduce the risk of damage.

1.3 HDPE Pond liner Generally Has Better Chemical Compatibility

Chemical compatibility is also different for its material components. Shrimp ponds need to use chemicals as fertilizers, pond conditioners, or water treatment agent, HDPE pond liners are known for the properties of chemical resistance with better protection against potential damage from these substances compared to EPDM pond liners.

1.4 HDPE Pond Liner Is Ease of Installation Onsite Than EPDM

Easy Installation is often preferred for HDPE Geomembrane HDPE pond liner as the roll size generally longer and wider compared with EPDM. GEOSINCERE HDPE Pond liner can be produced to be 8m or 10m width, while EPDM is much shorter to be 4m generally. And HDPE Liner can be prefabricated in large panels or rolls onsite. This makes the installation process more straightforward compared to EPDM liners. While for the EPDM it can only installed by adhesive which with shorter lifespan than the EPDM mother material. In this case, as long as adhesive lose function,the whole waterproofing system will become a failure in projects.

1.5 HDPE Pond Liner is More Cost Effective Than EPDM Pond Liner

Cost effectiveness become a prior consideration in project design. In the material cost, HDPE pond liner are more competitive than EPDM pond liner which is half less than the cost of EPDM liner.

And for the necessity of using the Pond liner,we can also talk about the drawbacks it will bring if not lay pond liner.

2. What Are The benefits of Pond Liner Material for Shrimp Ponds

Not using a pond liner in a pond can lead to some problems and challenges, and it will affect both the structural integrity of the pond and ecosystem of shrimp and fish.

2.1 Water Loss And hard To Do Aeration

Without laying HDPE pond liner, water will leak into the surrounding soil, leading to a loss and reduced water levels, especially in areas with permeable soil, will be erosion on slope.

For intensive shrimp farming ,another very important management will be the aeration. GEOSINCERE HDPE Pond Liner can create an ideal environment for aeration by the paddle wheel aerators. Aeration is essential in shrimp ponds to provide adequate oxygen levels for the shrimp and to maintain a healthy and productive aquatic environment. Shrimp, like all aquatic organisms, require oxygen for respiration. Aeration helps increase the oxygen levels in the water,especially in densely stocked ponds for higher output where the demand for oxygen is high. Aeration can also regulate water temperature in way of promoting oxygen exchange and preventing the formation of temperature stratification layers. Reason we mention this is because shrimp are ectothermic organisms, and if temperature in surrounding environment not stable,will affect their growth.  And another reason is for prevention of Hypoxia.  In extensively stocked shrimp ponds, oxygen levels can drop rapidly due to the high metabolic activity of shrimp and the decomposition of organic matter. From the original ,it is for improvement of Growth and Survival of the shrimp and fish in farming and prevention of stress and disease: Oxygen-deprived environments can lead to stress in shrimp, making them more susceptible to diseases. Aeration helps reduce stress levels by maintaining optimal oxygen levels, thereby enhancing the overall health and immune response of the shrimp. Also very good perspective ,ammonia and nitrite reduction,as the aeration promotes the breakdown of ammonia and nitrites, which are waste products excreted by shrimp and other pond organisms. Elevated levels of these compounds can be harmful to shrimp, and aeration helps mitigate their impact by supporting the activity of beneficial bacteria involved in nitrification.When the algae grows, aeration can help control the growth of algae as excessive algae can lead to oxygen fluctuations and negatively impact water quality. Aeration disrupts the conditions favorable for algal blooms.  Feed quality very important for aquaculture, and proper aeration can improve the distribution of feed within the pond, leading to better feed conversion rates. This is important for efficient shrimp farming and optimizing production.  Its rules also include dissolved carbon dioxide removal. Aeration helps remove excess carbon dioxide from the water, preventing the buildup of dissolved gases that can be harmful to shrimp and fish.
