6 Installation of Black Plastic Pond Liner for Waste Water Treatment Project
During the installation of black plastic pond liners for a waste water treatment project, it is essential to follow proper procedures to ensure the integrity and effectiveness of the liner. Here are some guidelines for installation:
1. Transportation: Take precautions while transporting the geomembrane pond liner to avoid contact with sharp objects that could puncture or damage it. Do not drag or drag the liner to prevent any potential harm.
2. Extending the Liner: The liner should extend from the bottom to a high position without being overly tight. Leave a margin of 1.50% to accommodate partial sinking and stretching. The slope should be paved from top to bottom, considering the specific requirements of the project.
3. Longitudinal Joints: Ensure that the longitudinal joints of two adjacent panels are not on a horizontal line. Stagger them by more than 1m to enhance the integrity of the liner.
4. Placement of Joints: The longitudinal joint should be situated more than 1.50m away from the dam foot and the bend foot, and it should be located on a plane for optimal performance.
5. Sequence of Installation: Begin by laying the liner on the side slope, followed by the bottom of the field. When laying the side slope, ensure that the film spreading direction is roughly parallel to the maximum slope line.
6. Acceptance Certificate: Obtain the corresponding acceptance certificate for the civil engineering work before laying the black plastic pond liners. This ensures compliance with project requirements.
7. Cutting and Numbering: Accurately measure the required size of the liner before cutting it. Avoid relying solely on size indications shown in figures. Each section should be numbered and detailed records should be kept using a specific form.
8. Minimize Welding Seams: When laying the geomembrane, aim to minimize the number of welding seams while ensuring the quality of the installation. This helps to save raw materials.
9. Overlapping Width: The joint between two membrane panels should have an overlapping width of at least 10cm. The welding seam should be arranged parallel to the maximum slope, following the direction of the slope.
10. Special Considerations: In corners and deformed areas, try to reduce the length of the joint as much as possible. Avoid setting up welds on slopes with a slope greater than 1:6 within 1.5 meters from the top slope or stress concentration area, unless specifically required.
11. Wrinkle Prevention: During installation, take care to avoid artificial wrinkles in the geomembrane. When the temperature is low, stretch the liner as much as possible and ensure it is laid flat.
12. Surface Protection: After the liner is laid, minimize walking and the movement of tools on its surface. Avoid placing any objects that could cause damage to the liner, ensuring the overall integrity of the anti-seepage membrane.
By following these guidelines, the installation of black plastic pond liners for the waste water treatment project can be carried out effectively, ensuring the longevity and functionality of the liner system.
Black plastic pond liners made from HDPE or LDPE geomembranes are a popular choice for waste water treatment projects in Indonesia. Their waterproofing capabilities, chemical resistance, UV resistance, flexibility, tensile strength, ease of installation, environmental compatibility, and cost-effectiveness make them a reliable and efficient solution for containing and treating waste water effectively.
