Using which kind of material depending on the application fields. BPM manufctured and exported HDPE geomembrane liner for tailings treatment project in Kenya.

The geomembrane Kenya can create a barrier against seepage and contamination. HDPE geomembrane liner can resist chemicals, offer durability, and remain flexible in harsh environments.

CASE STUDY

• Location :Kenya
• Product(s) : HDPE Geomembrane
• Application : tailings treatment project

Issue

The economic development increases the demand for mineral products and expands mining operations. The mining industry resulted in a significant rise in mineral tailings processing. Moreover, the available metal ores have lower grades nowadays.

To meet the growing demand, mineral processing will generate a substantial amount of tailings. The accumulation of these tailings poses numerous problems for the mining industry, environment, and economy.

Piled-up tailings are prone to flow and collapse, causing damage to vegetation and accidents. During the rainy season, the risk of collapse and landslides escalates. The high dam body of tailings ponds also presents potential safety hazards.

Tailings contain harmful components and residual beneficiation agents that inflict severe damage on the ecological environment. Particularly, tailings with heavy metals generate acidic water through sulfide reactions, leaching heavy metals and posing harm to the entire ecosystem.

The HDPE anti-seepage geomembrane exhibits high tensile resistance and mechanical properties. It is highly elastic, allowing for expansion and contraction of the base surface. Moreover, it effectively handles uneven settlement and has a high water vapor permeability coefficient.

The anti-seepage membrane demonstrates excellent chemical stability, making it suitable for sewage treatment, chemical reaction tanks, and landfills. It resists high temperature, asphalt, oil, tar, acid, alkali, salt, and more than 80 types of strong acids and alkalis. It also possesses exceptional anti-aging, anti-ultraviolet, and anti-decomposition capabilities, ensuring a service life of 50-70 years.

HDPE gemembrane liner exhibits high mechanical strength. It has a tensile strength at break of 28MPa and an elongation at break of 700%.

This geomembrane provides cost-effective and efficient anti-seepage solutions. Its production process is scientific, faster, and more economical than traditional waterproof materials, resulting in approximately 50% cost savings. It enables fast and convenient construction due to its high flexibility, various specifications, and hot-melt welding with high weld strength.

HDPE geomembrane Kenya has the anti seepage application for mining, heap leach tank, tailings yard, sewage storage pond, and more.

Following discussions with the customer, we agreed that geomembrane is the optimal choice for anti-seepage treatment. We supply the necessary materials based on the customer’s design and provide installation guidance.

1. Level the ground at the site, ensuring it is flat and compact. Remove any uneven objects, large stones, iron wires, or hard objects that could puncture the anti-seepage membrane.
2. Dig anchoring trenches measuring 40*40 around the landfill to prepare for anchoring the anti-seepage membrane on both sides.

HDPE geomembrane Laying 

1. Flatten the geomembrane roll in an open space and cut it into the required shape according to the plan.
2. During the geomembrane Kenya laying process, avoid artificial damage and ensure a smooth, tight installation with minimal wrinkles. Select the laying direction wisely to minimize stress on the joints. Arrange the material pieces reasonably and aim for wider joints.
3. When laying the geomembrane liner on a flat ground, calculate and choose the most suitable method to reduce welding seams and save materials. Avoid artificial damage during the laying process. Ensure proper alignment of welding seams between adjacent geomembranes. Consider the deformation and expansion of the geomembrane, typically 1%-4%, based on the site conditions, to prevent stress and tearing when the foundation deforms.
4. Immediately compress all exposed geomembranes with sandbags or heavy objects to prevent wind lift or displacement from the surrounding anchoring trench.

HDPE Geomembrane Welding

• For hot melt welding:
  • Overlap the geomembrane blocks by 15cm before welding.
  • Adjust the blocks to minimize wrinkles and “fish mouths” in the seams.
  • Clean the welding area to remove water, dust, and debris.
• For extrusion welding:
  • Overlap the geomembrane blocks by 7.5cm in the seams.
  • Clean the seaming area to ensure it is free of water, dust, and debris.
  • Use a hot air device for heating and bonding, avoiding damage to the geomembrane.
  • Keep the welding rod clean and dry.

Benefits

1. HDPE geomembrane has high tensile strength for demanding engineering projects.
2. It exhibits excellent chemical stability, resisting corrosion from strong acids, alkalis, and oil.
3. It has good heat and cold resistance, withstanding temperatures up to 110°C and as low as -70°C.
4. HDPE geomembrane is a flexible waterproof material with a high anti-seepage coefficient.
5. It possesses strong weather resistance and anti-aging properties, maintaining performance over time.
6. The geomembrane has high tensile strength and elongation at break, adapting to harsh geological and climatic conditions and uneven settlement.

Summary:

HDPE geomembrane Kenya is a high-polymer waterproof barrier material. It consists of high-quality virgin resin, with 97.5% high-density polymer, carbon black, anti-aging agents, antioxidants, ultraviolet absorbers, stabilizers, and other additives. It resists environmental stress cracking and chemical corrosion, operates within a wide temperature range, and has a long service life. It finds applications in biogas digesters, tailings storage, channel seepage prevention, dam seepage prevention, subway projects, and more.
