Key Advantages of Yixing Shenzhou HDPE Liners in Aquaculture:

The shift from traditional earthen ponds to HDPE-lined ponds offers significant operational and economic benefits:

1.Complete Water Containment & Seepage Prevention:

Benefit: This is the most crucial advantage. It prevents water loss into the ground,

which is critical in areas with low water tables or sandy, porous soils. This conserves water and reduces pumping costs.

2.Improved Water Quality and Management:

Benefit: The smooth, inert surface prevents soil and silt from mixing with the water, keeping it clearer.

It also eliminates interactions with underlying soils that might contain heavy metals, pesticides,

or other contaminants. This allows for precise control over water chemistry (pH, salinity, oxygen).

3.Disease and Parasite Control:

Benefit: The liner creates a physical barrier between the culture water and the natural soil,

which can harbor pathogens, parasites, and predators. This drastically reduces the risk of disease

outbreaks and simplifies pond disinfection between production cycles.

4.Ease of Harvesting and Cleaning:

Benefit: The smooth surface allows for easy and complete harvesting of stock using nets

or drain harvest systems. After harvest, the pond can be quickly cleaned, sterilized, and prepared for

the next cycle, reducing downtime.

5.Durability and Longevity:

Benefit: HDPE is highly resistant to punctures, UV radiation (thanks to carbon black),

and the chemicals used in aquaculture (like disinfectants). A properly installed HDPE liner can

last 20+ years, making it a cost-effective long-term investment.

6.Faster Pond Preparation:

Benefit: Unlike earthen ponds that may require drying and tilling between cycles,

HDPE-lined ponds can be cleaned, refilled, and stocked much more quickly, allowing for more production cycles per year.

Specific Considerations for Aquaculture HDPE Geomembrane Liner Applications

While HDPE is excellent, its application in aquaculture requires careful attention to specific details:

1.Liner Thickness:
For most aquaculture ponds, a thickness of 0.75 mm to 1.5 mm (30 to 60 mil) is standard.

Thicker liners (e.g., 1.5mm+) are used in larger ponds, in areas with rocky subgrades, or for species that might be more abrasive.

2.Textured vs. Smooth Surface:
Smooth HDPE: Is the most common and cost-effective. It is easy to clean and suitable for gentle slopes and tank bottoms.

Textured HDPE: Features a rough surface on one or both sides. It is highly recommended for aquaculture on slopes

because it provides superior friction, preventing the liner from slipping and allowing for safer access for personnel.

It also provides a surface for beneficial biofilm to attach without compromising cleanability.

3.Water Quality Safety:
It is imperative to use virgin, non-recycled HDPE resin that is certified for potable water

or aquaculture contact (e.g., NSF/ANSI 61 certification). This ensures no harmful plasticizers

or chemicals leach into the water and affect the stock.

4.Aeration System Protection:
The high-impact points from aeration systems (air stones, diffusers) can cause abrasion on the

liner over time. It is common practice to place a protective mat or an extra layer of geotextile under these high-traffic areas.

5.Underlayment Protection:
A non-woven geotextile underlay is strongly recommended. It cushions the HDPE liner from sharp stones,

roots, and irregularities in the subgrade, protecting it from punctures.

6.Slope Design:
Proper slope (typically a ratio of 2:1 or 3:1) is critical for structural stability and for directing waste toward the drain for easy removal.

Aquaculture HDPE Geomembrane Liner  Installation and Maintenance :

Subgrade Preparation: The earth must be properly compacted, smooth, and free of all sharp

objects (roots, rocks). This is the most critical step for a successful installation.

Expert Seaming:

All field seams must be made by certified welders using thermal fusion (wedge or extrusion) and tested rigorously

(e.g., air pressure, vacuum box) to ensure a watertight seal.

Anchoring:

The liner must be securely anchored in a perimeter trench ("anchor trench") to hold it in place when the pond is filled.

Cleaning and Disinfection:

Between cycles, the liner can be pressure-washed and disinfected with approved chemicals

(e.g., chlorine, potassium permanganate) that are compatible with HDPE.
