The pollution of industrial waste is particularly serious. It usually contains many chemical elements that we do not commonly see, and some can cause damage to human skin or body. Its degree of harm has exceeded that of domestic waste. If not properly disposed of, it will cause irreversible consequences to the environment, especially for soil, groundwater, etc., circulating back and forth, and...

Reservoir dams usually have fishways for fish to pass upstream and downstream. Fishways are usually divided into downstream section, upstream section, and culvert section. Among them, the downstream section usually adopts a "U" shaped cross-section design, while the culvert section is designed as a door-shaped structure. For the entire fishway, its main body is formed by reinforced concrete po...

Extrusion welding is the main finishing technology for polyolefin geomembrane materials such as HDPE. Extrusion welding is a finishing technology in which molten plastic beads are used to weld thermoplastic geomembrane materials. The quality of extrusion welds depends on the skill of the welder operator. Extrusion welders use a heated barrel with a plasticizing screw to deliver molten plastic ...

When installing a new geomembrane, the occurrence of wrinkles can be said to be too common. Small wrinkles can turn into cracks under pressure. This, in turn, can compromise the integrity of the entire geomembrane installation and cause costly damage. In this article, we will take a closer look at the causes of geomembrane wrinkle formation and how to avoid them. What causes geomembrane wrinkl...

To purify water, water treatment facilities need to ensure that water passing through the system is sufficiently exposed to appropriate levels of chlorine. One method is to use geomembranes. Outlined below are three ways geomembranes can be used to help address the drinking water crisis. 1. Curtains and baffles Drinking water geomembrane can be used to make curtains or baffles for drink...

Determining the cost of large pond geomembrane requires more than just choosing the cheapest material per square meter. All elements of the project need to be considered, including the obvious pond size, but also the purpose of the pond, expected life, slope and depth, whether the water is still or flowing, and transporting the membrane material to the site and who is handling the installation...
Learn moreIf your fish pond is laid with geomembrane, then maintaining it and keeping it healthy should be a top priority, especially for the fish, flora and fauna in it. The entire ecosystem relies on you to keep its normal use function. To maintain a geomembrane fish pond, you must complete the following three things. You need to aerate the pond. This is achieved by installing an appropriate aeration ...
