Heavy Duty Pond Liner for Waste Water Treatment in Thailand
Heavy duty pond liner is the kind of highly flexible and robust HDPE geomembrane pond liner specially engineered for small to medium waste water containment ponds or other applications. Due to the rapid development of industry, there are many kinds and quantities of of industrial wastewater, and the pollution of water body is becoming more and more widespread, which seriously threatens human health and safety. The water of sewage pool is mainly acidic and alkaline, toxic and harmful substances. Temperature changes will occur in the process of water treatment, so the requirement of anti-seepage of the pool is relatively high. BPM heavy duty pond liner is acid and alkali resistant, corrosion resistant, it can resist corrosion of more than 80 kinds of strong acid and alkali and other chemical media, and has good impermeability, the water vapor permeability coefficient K heavy duty pond liner as the anti seepage lining system, which has good economic benefit, low comprehensive cost, low investment and meets the standards of sewage impermeability prevention.
Thailand is one of the fastest developing countries in Southeast Asia. With the development of economy, the Thai government is more stringent in environmental protection. All sewage treatment ponds in factories are required to lay geomembrane pond liner in order to avoid leakage of sewage. BPM heavy duty pond liner has a wide market in Thailand. The local steel processing plants contacted BPM through our distributors. In order to ensure the quality of heavy duty pond liner, we sent samples of different thickness to customers. Through quality testing, our HDPE geomembrane pond liner samples met ASTM GRI GM 13 Standard in strength, anti-ultraviolet, anti-oxidation and other aspects. In order to increase the service life, Thai customers ordered 10,000 square meters with thickness 2.0mm to lay heavy duty pond liner for the wastewater pond near their Thai factories.
pecifications of Heavy Duty Pond Liner for Waste Water Treatment in Thailand
• Total quantity – 10,000 square meters
• Each roll size – 7m×100m
• Thickness – 2 mm
The following characteristics of heavy duty pond liner of determine its important position in the field of seepage control:
1. Chemical stability – heavy duty pond liner has excellent chemical stability, resistance to high and low temperature, asphalt, oil and tar, acid, alkali, salt and other 80 kinds of strong acid and strong alkali chemical media corrosion.
2. Anti-aging properties – heavy duty pond liner has excellent anti-aging, anti-ultraviolet, anti-decomposition capabilities, can be used barely, material life of up to 50-70 years, providing a good material guarantee for environmental anti-seepage.
3. Anti-plant Root System- heavy duty pond liner has excellent anti-puncture ability and can resist most plant roots.
4. High mechanical strength-HDPE geomembrane pond liner has good mechanical strength, breaking tensile strength 28 MP, breaking elongation 700%.
5. Low cost and high efficiency – HDPE geomembrane pond lineruses new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the cost of products is lower than that of traditional waterproofing materials. Practical calculation shows that the general project using HDPE anti-seepage film will save about 50% of the cost.
6. Fast construction speed – HDPE geomembrane pond liner has high flexibility. There are many laying forms and specifications to meet the requirements of different engineering anti-seepage. Hot-melt welding is adopted, the weld strength is high, the construction is convenient, fast and healthy.
7. Environmental protection and non-toxicity – HDPE geomembrane pond liner is made of non-toxic and environmental protection materials. The anti-seepage principle is a general physical change without producing any harmful substances. It is the best choice for environmental protection, aquaculture and drinking ponds.
8. Welding effect is good – HDPE geomembrane pond liner using special welding machine has very good welding effect. The strength of weld is greater than that of base metal, and it is easy to construct.
