1 What is HDPE Circular Pond Liner?
HDPE circular pond liner refers to a geomembrane liner made of High-Density Polyethylene (HDPE) specifically designed for circular or round-shaped ponds used in shrimp or fish farming projects.
In shrimp or fish farming, geomembrane pond liners play a crucial role in providing water containment, protection, and maintaining the overall health of the farm ponds. The HDPE geomembrane tank lining serves as the foundational element of the shrimp or fish farm, ensuring a reliable barrier between the water and the surrounding environment.
Circular pond liners offer several advantages for shrimp or fish farming applications. The circular shape allows for efficient use of space and facilitates better water circulation within the pond. This circulation can help maintain water quality, oxygen levels, and overall environmental conditions necessary for the healthy growth of shrimp or fish.
HDPE is a popular choice for pond liners due to its unique properties. It offers excellent resistance to UV radiation, chemicals, and punctures, ensuring long-term durability and protection against potential leaks. HDPE liners also have high tensile strength and flexibility, allowing them to adapt to the contours of the pond and withstand various environmental conditions.
By using HDPE circular pond liners, shrimp or fish farm operators can establish a secure and reliable containment system for their ponds. This helps to prevent water loss, maintain water quality, and create a suitable environment for the growth and development of shrimp or fish.
It is important to note that the selection and installation of an appropriate HDPE circular pond liner should be based on factors such as the size of the pond, water depth, soil conditions, and specific requirements of the shrimp or fish species being cultivated. Consulting with experts or suppliers experienced in shrimp or fish farming pond liners can provide valuable guidance to ensure the optimal performance of the liner system.

3 Why Chose HDPE Circular Pond Liner for Shrimp Pond Project in Ecuador
When considering a shrimp pond project in Ecuador, there are several reasons to choose HDPE circular pond liners:
- Soil Conditions: In coastal areas of Bangladesh, where shrimp farming is common, the land is often swampy, sandy, or comprised of organic soils. These types of soils are not suitable for traditional crop cultivation and can pose challenges for pond construction and maintenance. HDPE circular pond liners provide a reliable barrier between the pond water and the surrounding soil, preventing water loss and maintaining optimal conditions for shrimp growth.
- Acid Sulfate Soils: Some areas may contain pyrite, which can lead to low pH levels that are detrimental to shrimp farming. HDPE circular pond liners act as a protective layer, preventing the acidic soil from affecting the water quality in the pond and ensuring a suitable environment for shrimp cultivation.
- Water Retention: Sandy soils have poor water-holding capacity, making it difficult to maintain water levels in the ponds. HDPE circular pond liners prevent seepage and water loss, allowing for efficient water management and maintaining the desired water depth for shrimp farming.
- Stability and Oxygen Demand: Organic soils can be unstable and have a high oxygen demand. HDPE circular pond liners provide stability to the pond infrastructure, preventing erosion and maintaining the structural integrity of the pond. Additionally, the liners reduce oxygen demand, ensuring a healthier environment for shrimp while minimizing the risk of disease outbreaks.
- Drainage and Drying: Low-lying terrain in these areas can pose challenges for drainage and drying of ponds after harvest. HDPE circular pond liners facilitate effective drainage, allowing for proper water removal and drying of the pond bottom. This helps to maintain optimal pond conditions and prevent the deterioration of the pond bottom, reducing stress on the shrimp and minimizing the risk of diseases.
Our Ecuador customer left a message on social media Facebook telling us that he needed to purchase geomembrane for shrimp ponds and asked about the price of the product. In Bangladesh, shrimp farming is usually carried out in coastal areas because of the availability of brackish or seawater supply ponds. Also, the land is swampy or sandy, and sometimes organic soils may appear. Such land is not suitable for growing crops or plantations, and the price is relatively cheap. Such land is also used to build ponds, and ponds built in soils that contain pyrite (potentially acid sulfate or active acid sulfate soils) can create low pH levels, which can cause problems for shrimp farming. Ponds built in sandy soil do not hold water well. Organic soils do not allow stable dikes and have a high oxygen demand. Due to the low-lying terrain, shrimp ponds built in these areas face difficulties in drainage and drying after harvest. The bottom of the pond is not completely dry, and after a few prawns have been raised, the bottom of the pond can deteriorate, which can stress the prawns and facilitate disease outbreaks.
4 Solution of HDPE Circular Pond Liner for Shrimp Pond Project in Ecuador
The customer shrimp farming in Bangladesh encountered the above problem. After communicating with our company, we recommended the customer to use a 0.5mm geomembrane circular pond liner. This method separates the pond water from the soil. Due to its durable and unbreakable characteristics, HDPE circular pond liner not only effectively prevent weeds, sludge and other obstructive pollutants from entering the pond, but also reduce the bacteria in the pond environment, thereby reducing the use of antibiotics. In addition, geomembranes also protect pond slopes from erosion and are extremely convenient for servicing and quick removal of sediment and waste. We provided customers with 0.5mm geomembrane pond liner samples for testing. After receiving the samples for testing, the customer was very satisfied with the results. The customer purchased a 0.5mm geomembrane for use in a shrimp farming plant. Our team also provides customers with professional advice and guidance on the installation of geomembrane. During the installation process, we wholeheartedly considered the customer, gave the customer a detailed description of the specific steps of the installation, and reminded the customer to pay attention to three points:
(1) Before laying, the laying surface should be leveled and compacted, and sandbags or heavy objects should be prepared to prevent the laid HDPE geomembrane from being blown away by the wind.
(2) The slope of the breeding pond should not exceed 45°C, otherwise it is easy to collapse and it is not convenient for breeding.
(3) The anchoring ditch shall be dug into a U-shaped ditch or inverted trapezoidal ditch of 40cm-50cm, and then backfilled with soil.
