HDPE Geomembrane is used in aquaculture in Southeast Asian countries

l Definition

HDPE geomembrane is a waterproof barrier material made of (medium) high density polyethylene resin as the main raw material, adding carbon black, anti-aging agent and other auxiliary materials. It has excellent environmental stress cracking resistance, low temperature resistance, anti-aging, corrosion resistance and other properties, and is widely used in various seepage prevention projects.

l Application advantage

1. Excellent anti-seepage performance:

Southeast Asia is rich in precipitation, the groundwater level is high, HDPE geomemofilm has a very low permeability coefficient, which can effectively prevent the water in the pond from leaking into the ground, maintain the stability of the aquaculture water level, and reduce the waste of water resources.

2. Protection of water quality:

it can prevent harmful substances in the soil, but also prevent pollutants such as waste, residual feed and feces generated during the breeding process from penetrating into the ground, avoid pollution to the groundwater and the surrounding soil environment, and provide a good living environment for aquaculture organisms.

3. Reduce the risk of disease transmission:

Separating aquaculture water from soil reduces the possibility of disease transmission, helps to reduce the occurrence of diseases in aquaculture, improve the survival rate of aquaculture, and reduce the cost of drug use.

4. Improve breeding efficiency:

The bottom of the pond is smoother, easy to clean up waste and fishing operations in the pond, reduce the difficulty and workload of manual cleaning, and improve the efficiency of breeding management.

5. Adapt to complex terrain:

 Some parts of Southeast Asia terrain complex, HDPE geomembrane has good flexibility and adaptability, can be laid according to different pond shape and terrain, whether flat, slope or irregular shape of the pond, can be better fit, effective use of land resources.

6. Strong durability:

 with excellent anti-aging, anti-ultraviolet and anti-corrosion properties, it can be used for a long time in the hot and humid climate conditions in Southeast Asia, and the service life is generally up to decades, reducing the cost and workload of frequent replacement of breeding facilities.

l Application example

Sri Lanka:

The aquaculture farm in Sri Lanka uses 0.6mm HDPE geomembrane lining. The Geomembrana HDPE geomembrane lining has good tensile resistance, impact resistance, tear resistance and high hydrostatic resistance. It has outstanding effect in acid and alkali corrosion resistance, microbial corrosion resistance and seepage resistance, which can cut off virus transmission and play a disinfection role. Reduce breeding costs.

 It has been applied in traffic engineering in Vietnam, Laos and other countries.

7. In the agricultural sector:

(1) Seepage prevention of reservoirs, drinking pools and storage ponds:

 It is widely used in agricultural countries such as Thailand and Cambodia.

(2) Seepage prevention of irrigation systems: 

agricultural irrigation areas in countries such as Malaysia and Indonesia.

(3) Aquaculture industry:

The linings of aquaculture ponds, fish ponds and shrimp ponds are widely used in countries with developed aquaculture such as Vietnam and the Philippines.

l Summarize

HDPE geomembrane has significant advantages in aquaculture in Southeast Asian countries, providing strong support for the development of aquaculture industry. With the continuous development of aquaculture industry in Southeast Asia and the increasing requirements for environmental protection and efficiency, the application prospects of HDPE geomemofilm will be broader, which is expected to bring greater development opportunities for the aquaculture industry in the region and help it achieve sustainable and efficient development goals.
