1. Process

Reverse hanging membrane: the reverse hanging membrane is a sewage pool sealing method that uses steel structure as the support structure, and the membrane material is suspended reversely on the steel structure and fixed by bolts.

Suspension membrane: suspension membrane is a kind of structure without skeleton support, which is only suspended by flexible cables and other components.

2. Cost

The two sewage pool sealing processes are different, and there are some differences in cost. Generally, the cost of hanging cable anti hanging membrane is more cost-effective, especially for large-span sewage pool sealing.

3. Scope of application

Reverse hanging membrane: due to its supporting structure, the reverse hanging membrane can seal all types of sewage pools, with unlimited span and design of any access door and window.

Suspension membrane: the suspension membrane requires a column in the middle of the sewage pool, and because it is laid flat on the sewage pool, equipment maintenance cannot be carried out, so it is generally covered on the sewage pool without equipment.
