Loresco type SWS® is designed for use in impressed current surface systems. SWS® is also suitable for containerized anode systems and semi-deep impressed current systems. SWS® may be poured dry or through water or light mud.

Loresco SWS® exhibits a hard, round shape and does not require tamping because of its ability to go full density with simple pouring. The bulk density of SWS® is 68 lbs. per cubic foot. The predominant particle sizing ranges from 1mm to 5mm with no particle larger than 12mm.

The manufacture of SWS® is in a highly controlled "hot" atmosphere which produces a particle surface with wettable characteristics. This allows SWS® to be freely poured directly into water or light mud without sacrificing system integrity due to poorly compacted carbon. Set-up time is almost instantaneous.

Loresco SWS® is a product designed to be placed in the earth. According to EPA-approved leacherate tests, SWS® meets all purity requirements for materials utilized in underground burial.


  • Bulk Density: 68 lbs. per cubic foot.
