- Location – US
- Product(s) -Polyethylene Pond Liner
- Application – Salt Pond
Issue
Fresh water supply is a global issue in many areas related to access and availability. Geosynthetics has been an important factor in environmental waterproofing solutions for a long time. Solar and pool systems are designed to address the need for fresh water shortages, agricultural drainage cleanup, and low-cost renewable energy. American customer wanted to build a salt pond, the heavy duty plastic pond liner is the ideal and cost effective geosynthetic material as the anti seepage lining system.
Solution
1. Overview
The scope of the project includes a salt gradient solar pond, which contains a flexible heavy duty plastic pond liner system, and with the help of a main thruster (engine) designed to extract power directly from the hot salt water of the pond. The goal of pond performance is to distill salt water into fresh drinking water and energy. BPM’s innovative system provides a renewable water source for water derived from agricultural wastewater, brackish water/salt water (or sea water) and sunlight. The project and its design are still of great significance as a portable technology that can provide a catalyst for the systematic conversion of large amounts of usable brine into renewable energy and fresh drinking water.
2. Challenges
The project faces many challenges. One is the sandy soil roadbed, which is a dry and dusty site. The area needs to be kept moist and rolled daily to maintain compaction and stability. The other is the high temperature in this desert location, which reached 115°F (46°C) in June. The staff work as planned from 10 pm to 8 am to avoid the on-site personnel from being heated and to keep the welding temperature under control. The high winds meant that the team had to secure each polyethylene liner with sandbags immediately after deployment and installation. Finally, the containment of the hot brine in the distillation tank is another factor in the design discussion to find a suitable flexible lining for the containment.
3. Factors
The heavy-duty plastic pond liner selected for the project had high temperature resistance, dimensional stability, and easy handling and sealing. 130 polyethylene liners measuring 220 x 96 feet (67 x 29 meters) and 540 ballast tubes were manufactured off-site and delivered to the project site in the US. The construction was completed in 28 days, surpassing the initial estimate of 35 days, resulting in cost and time savings. Effective communication and planning contributed to the project’s timely completion. The modular structure prefabricated factory panels reduced on-site joints by over 50%. Overall, the project achieved high-quality performance and successful implementation of solar and water infrastructure.
Benefit
Heavy duty plastic pond liner meets the requirements of today’s environmental engineering field. The main motivation of the BPM HDPE geomembrane pond liner is to keep it natural and clean. Choosing suitable anti-seepage materials in the project to improve the compactness of the dam. As a new type of impermeable geosynthetic material, polyethylene liner has been widely used in the reservoir area due to its high tensile strength, good impermeability, strong deformability, light weight, convenient construction, and low cost.
Summary
1. Base surface requirements for HDPE pond liner construction
The surface of the installation base should be tamped and leveled, and sharp objects such as tree roots and stones should be removed; the internal and external corners of the base should be trimmed and rounded, and the radius of the corner should be ≥50cm; the surface of the welding seam must be cleaned up; the civil engineering, supervision, owner, and construction party must accept and sign Polyethylene liner construction can be carried out after approval.
2. Climatic requirements for geomembrane pond liner construction
The temperature should generally be above 5℃, the HDPE pond liner should be tense at low temperature, and the Heavy Duty Plastic Pond liner should be relaxed at high temperature.
3. Laying of HDPE pond liner
Laying Heavy Duty Plastic Pond liner is a key process in the entire anti-seepage system. Before cutting the geomembrane pond liner, measure its relevant dimensions, and then cut it according to the actual cutting. The overlap width of the seam between the membrane and the membrane during the membrane laying is 10cm～15cm, so that the direction of the seam arrangement is parallel to the slope foot line , That is, arranged along the slope direction.
4. Welding of HDPE pond liner
Heavy Duty Plastic Pond liner is welded using a dual-drive self-propelled Polyethylene liner welding machine, and dual-track hot-melt welding is used. For parts that cannot be welded by the welder, an extrusion hot-melt welder should be used with welding rods of the same quality as the raw materials to form a single weld seam for surfacing.
5. Anchoring of HDPE Pond liner
Choosing suitable anti-seepage materials in the project to improve the density of the dam body can effectively prevent the disasters of the tailings pond. As a new type of anti-seepage geosynthetic material, Laying Heavy Duty Plastic Pond liner has high tensile strength , Good anti-seepage performance, strong deformability, light weight, convenient construction, low cost, etc., have been widely used in the whole and part of the dam building (structure) in the reservoir area.
