High Tensile Strength Low Permeability 1mm 40Mil Wastewater Treatment Plant HDPE Geomembrana Water Lagoons

Yixing Shenzhou Geosynthetics HDPE geomembrana in wastewater treatment plants is a critical application for

environmental protection and operational efficiency. While the core material is the

same as in landfills, its specific roles and configurations are different.
Here is a detailed look at how HDPE geomembranes are used in wastewater treatment plants.

HDPE geomembranes serve as impermeable barriers in several key areas within a wastewater treatment plant:

1.Aeration Lagoons and Treatment Basins:

Function: These are large, open basins where wastewater is biologically treated.

The geomembrane lines the entire basin to prevent untreated wastewater from seeping into

the groundwater and to contain the water for proper treatment.

Benefit: Provides a robust, chemical-resistant barrier against the water, microbes, and treatment chemicals.

2.Anaerobic Digesters:

Function: These are sealed tanks or lagoons where microorganisms break down organic matter

in the absence of oxygen, producing biogas (methane and CO₂). HDPE is used to line the digester

and is also the primary material for floating covers.

Benefit:
Containment: Prevents seepage of the highly concentrated organic waste.

3.Gas Collection:

A floating HDPE cover captures the valuable biogas, which can be used to generate electricity for the plant.

Odor Control: The sealed cover contains unpleasant odors.

Equalization Tanks (EQ Tanks):

Function: These tanks hold incoming wastewater to smooth out fluctuations in flow and composition before

it enters the main treatment process. Lining them with HDPE is essential for containment.

4.Clarifiers and Settling Tanks:

Function: These tanks allow solids to settle out from the water. Lining them prevents contamination of the subsoil.

5.Sludge Drying Beds:

Function: These are beds where dewatered sludge is laid out to dry further.

An HDPE liner prevents the nutrient-rich (and potentially contaminated) leachate from the sludge from polluting the groundwater.

6.Emergency Storage & Stormwater Ponds:

Function: Plants use these ponds to handle overflow from heavy rainfall or system upsets.

Lining them ensures that this untreated or partially treated water is contained for later processing.

7.Containment for Biogas-Holding Areas:

Sometimes, HDPE geomembranes are used to create impermeable pads around digesters and gas

handling equipment to contain any potential spills.

Why is Yixing Shenzhou Wastewater Treatment Plant HDPE Geomembrana​ ?

1.Excellent Chemical Resistance: HDPE is highly resistant to a wide range of chemicals, acids,

and alkalis found in landfill leachate. It won't degrade easily when in contact with these harsh substances.

2.Very Low Permeability: Its dense molecular structure makes it virtually impermeable to fluids and vapors,

effectively creating a barrier that contains leachate and landfill gas (methane, CO₂).

3.High Durability and Strength: HDPE has high tensile, tear, and puncture resistance,

which is crucial during installation and when supporting the weight of overlying waste and drainage layers.

4.Cost-Effectiveness: Compared to other liner materials like clay or specialized polymers,

HDPE offers a superior balance of performance and cost for large-scale projects like landfills.

5.UV Resistance: Modern HDPE geomembranes are manufactured with carbon black (2-3%),

which provides excellent resistance to ultraviolet (UV) radiation, preventing degradation from sun exposure before being covered.

6.Proven Long-Term Performance: When manufactured and installed correctly,

HDPE liners have a demonstrated service life that can exceed hundreds of years under landfill conditions.
