The bag is made of a close weave textile which aids the dewatering process. Sedi-filters are engineered to withstand pressure at the base. The Sedi-filters can be made to almost any size to suit your application’s needs, please speak to a member of our team for more details. The standard size is 7m wide x 30m long with a volume of approximately 250m3.
Filling the bag
Filling is via pumping material into the system through one of three or more dorsal openings on the upper side of the Sedi-filter. The dorsal openings at the top centre of the bag comprise of an entry port with a sleeve, this allows a pipe to be inserted and clamped inside the sleeve. Filling is controlled through a manifold/valve system, each tube is filled and allowed to dewater through the small holes in the material. Once dewatered, the Sedi-filter is filled again and the process is repeated until the dewatered sediment fills approximately 80% of the bag’s volume.
Treating the slurry
A wide variety of treatments can be applied to the slurry during and after pumping. Air lines can be run through the bag and clamped in place so that microbes can be added. Mixing and agitation can also be used to disperse treatment chemicals throughout the slurry.
