There are two ways to cover large-span pools on the market: FRP and anti-hanging membrane.
The industries with large sewage treatment capacity in my country are chemical plants, paper mills, pharmaceutical plants, municipal sewage treatment plants, etc. Their cesspools have one thing in common, they span a large span.
When the span reaches a certain level, it is recommended to use anti-hanging film to cover. In a small area, the price of FRP is lower than the anti-hanging membrane, but if it is a large-span pool, the overall price of FRP is more expensive. The main material of FRP is fiber-reinforced plastic. As the area increases, the amount of material used increases. At the same time, the weight increases, the lifting volume increases, and the cost increases.
The reverse-hanging membrane membrane material of the sewage tank is light and has strong tensile strength. It is especially suitable for large-span pools. The larger the span of the pool body, the better the membrane material price per square meter and the better deodorizing effect.
