Geotextile dewatering are also known as dewatering bags, geotextile tubes, geotextile containers, soil tubes, geosynthetic tubes, or dredging bags. They are made of high-strength woven polypropylene geotextile fabric, which is resistant to UV rays, environmental corrosion, and biodegradation.
PENNDRATE is a kind of high-tenacity polypropylene dewatering fabric container, provides excellent solids retention and rapid discharge of high-quality filtrate. It is high-strength, anti-UV, durable, and cost effective.
1. Can be customized according to needs.
2. Good dredging, drainage and filtration effects.
3. Wide range of uses.
4.High strength woven geotextiles
5.Cost effective and low maintenance
6.Effective in draining silt, sediment, sludge and contaminated waste
7.Designed for large drainage projects
When slurry is pumped into the dewatering bag, water flows out through the fabric while the solids remain inside the bag. Eventually, fine solid particles will accumulate a “filter cake” on the surface of the geotextile bag. The outer layer of the geotextile bag acts as a “filter membrane,” allowing clean water to flow out while retaining the solids within the bag.
