The absolute best way to reclaim valuable materials
We use geotextile bags (filter bags) for passive dewatering interventions. This option creates a low maintenance and cost effective solution that can remove more water from contaminated material and sediment that already exists in treatment ponds, tailings ponds, stormwater management ponds (SWMPs), and industrial lagoons – allowing you recoup valuable materials that may have been missed in previous operations.
Protect the environment
Containment of solid material in geotextile bags means contaminants are removed from the surrounding environment for safe disposal.
Lower disposal costs
Since we produce a higher rate of solid material when dewatering, this ensures you’re only trucking away and disposing of contaminated solids and not excess water.
Flexible disposal timelines
Geotextile bags provide you with a long term storage solution for material containment.
HOW IT WORKS
Filter bags are made from a specially engineered textile made from high tenacity polypropylene or polyester yarns, which are woven into a stable network that retains their relative position. This material is inert to biological degradation and resistant to naturally found chemicals, alkalis, and acids.
To ensure optimal dewatering, a polymer solution is injected into the sludge being pumped into the bags. The polymers connect with solid particles and draw them away from the water molecules. As the sludge pushes into the bags, the water escapes through the bag’s exterior filter, while the sediment is contained. The bags decant for several weeks to ensure maximum dewatering.
WE’LL PROVE IT
This geotextile method, combined with polymers to speed up the process, is an efficient
and effective sludge dewatering solution that saves you time and money, while maintaining the best
environmental practices and safety standards.
