60mil HDPE Plastic Liner for Salt Evaporation Pond Project in Indonesia

HDPE plastic liner, also known as HDPE geomembrane liner, is the ideal and cost effective geotechnical lining material for salt evaporation pond. The HDPE plastic liner is made of high-density polyethylene using three-layer co-extrusion and blown film technology, adding about 2% carbon black, antioxidants, anti-aging and anti-ultraviolet components. HDPE geomembrane liner has excellent chemical resistance and UV resistance, impermeability, high yield strength and weld strength, and is widely used as a lining system for civil engineering projects. 60mil HDPE plastic liner is suitable for anti-seepage in special industries, and is widely used in aquaculture, anti-seepage, reservoirs, sewage treatment ponds, mines and landfill projects.

Case Study

• Country – Indonesia
• Product – 60mil HDPE Geomembrane Liner
• Purpose – Salt evaporation pond

Issue

We received an inquiry for geomembrane from a Indonesia customer on the Google website. The customer asked if our geomembrane HDPE plastic liner could be used in the salt evaporation pond project. Indonesia has the world’s second longest coastline after Canada, stretching more than 54,000 kilometers, but most of the salt it consumes is still imported. Through communication with customers, we learned that customers use traditional salt production methods to get salt. Sea salt production uses seawater as raw material, Seawater is introduced into salt evaporation ponds through channels. After evaporating for 25-28 days, the salt crystals are transferred to the salt platform for drying. It takes about 4-10 days, depending on the weather.

In this way, customers can produce and harvest salt three times a year. Using this traditional method of sun-dried sea salt, the problem is that the output is low, and the customer wants to increase the output of the salt field under the same conditions, thereby increasing the income.

Solution

We recommended our 60mil HDPE geomembrane to our customer for use in his salt evaporation pond project. Because the brine in the evaporation pond is corrosive, it is necessary to use high quality 100% vergin material geomembrane lining at the bottom of the pond to extend the service life and reduce the impact on the environment. HDPE geomembrane lining is used for salt pond anti-seepage. If the weather is good, the daily salt output can usually be about 60% more than the daily.

According to the size of the salt evaporation pond given by our customer, we calculated that our customer needs 50,000 square meters of 60mil HDPE geomembrane. We offered our best price of the 60mil HDPE geomembrane and our case for salt pond to our customer, and tell our customer how to install the geomembrane. Customers are satisfied with our professional project experience and super high-quality products. So we provided the customer with a 60mil HDPE geomembrane test report, factory certificate and free samples. The customer was very satisfied after receiving the samples, and soon we got the order.

Specification of 60mil HDPE Plastic Liner for Salt Evaporation Pond in Indonesia

Benefits

1. The finished product of HDPE plastic liner is black high-strength coiled material, which has high abrasion resistance and light and heat absorption performance. It can absorb and convert natural sunlight into heat energy. Speed up the evaporation of water, increase the speed of salt crystallization and separation, and greatly increase the salt production per unit area.
2. The HDPE plastic liner will not produce harmful substances at high temperature like the material, and it has the infinite safety performance of the finished salt.
3. After using HDPE plastic liner as the anti-seepage isolation of the salt pond, it is helpful to maintain the cleanliness of the salt and reduce the impurity components, and the unit price is high.
4. After using HDPE geomembrane as the anti-seepage and isolation of the salt pond, it is conducive to the collection of crystalline salt to increase the output.
5. HDPE geomembrane has high strength and abrasion resistance, high return on investment and high return on investment, saving the land use area of the salt drying field and having good economic benefits.

Installation of 60mil HDPE Geomembrane Liner for Salt Evaporation Pond in Indonesia

1. The base surface of the HDPE plastic liner construction requires that the surface of the installation base should be tamped and leveled, and sharp objects such as tree roots, stones, glass and iron nails should be removed; the internal and external corners of the base should be trimmed and rounded, and the fillet radius ≥50cm, and the surface of the welding seam should be cleaned. Clean; the construction of geomembrane can be carried out after the acceptance and signature of the civil engineering and supervision construction party;
2. The climate requirements for geomembrane construction should generally be above 5℃. The HDPE plastic liner should be tight at low temperatures, and the geomembrane should be relaxed at high temperatures. Geomembrane installation and construction should be appropriately pre-released to an extension of 2% to 5% according to the specific site conditions and the prevailing climatic conditions; the wind is below; when the temperature is too low, the construction should not generally be carried out in strong winds or rain and snow above level 4; in windy weather, When the wind affects the construction of the geomembrane, the geomembrane to be welded should be pressed firmly with big rocks or sand bags;

3. The laying of geomembrane. The laying of HDPE plastic liner is the arrangement direction of the seam in the entire anti-seepage system parallel to the slope toe line, that is, it is arranged along the slope direction. When laying HDPE plastic liner, we should try to minimize the number of welds. Under the premise of ensuring quality, we should save raw materials as much as possible, and it is also easy to ensure quality. Usually in corners and deformed areas, the length of the joint should be as short as possible. In addition to requirements, on slopes with a slope greater than 1:6, within 1.5m from the top slope or stress concentration area, try not to install welds;

4. During the laying of the HDPE plastic liner, artificial wrinkles should be avoided. When the temperature is low, it should be stretched and flattened as much as possible. After the geomembrane is set up, it is necessary to minimize walking and moving tools on the surface of the geomembrane. Anything that can cause harm to the geomembrane should not be placed on the geomembrane or carried on the film to avoid accidents to the geomembrane. damage;

5. For the more critical process, the appearance quality of the HDPE plastic liner is unpacked and inspected before the film is laid, and the discovered mechanical damages, production wounds, holes, breakages and other defects are recorded and repaired. Before cutting the geomembrane, measure its relevant size, and then cut it according to the actual cutting. The lap width of the seam between the membrane and the membrane is 10cm~15cm, so that the direction of the seam arrangement is parallel to the slope foot line, that is, along Arrangement in slope direction;

6. In addition, in order to better guarantee the effect of the HDPE plastic liner construction, it is also necessary to pay attention to when laying the geomembrane, do not pull it too tightly, and leave a certain amount of expansion and contraction. At the same time, it should be noted that the protective layer must be well covered to avoid some heavy objects from damaging the geomembrane.
