The results provide a reliable technical basis for the selection and sizing of a full-scale Filter Press plant, with membrane plates for clarifier sludge dewatering, as well as materials handling.
- Date: 31 March 2026
- Client: Filtaquip (Pty) Ltd
- Project Type: FILTRATION OF SCRUBBER DUST
Objectives of this Project
1. To assess:
- Filtration behaviour,
- Cake formation time, and
- Final moisture content
-
2. Assess optimal operating conditions:
- Chamber depth
- Membrane squeeze and Air-blow
It was essential to obtain a dry cake as possible, as it will be fed
back to the Furnace!
Background
The Client’s Smelter consists of a Furnace that produces an off-gas which is very harmful to the environment, so a Scrubber is used to
capture the dust, which forms a slurry, which is then pumped into a slurry Storage Facility. However, this handling method presents further environmental challenges. Filtaquip offered a solution to convert the
Scrubber slurry into a dry filter cake, which is then recycled back into the Furnace, enabling the valuable metals to be recovered. As the
solids have commercial value, the Client’s overall revenue was improved, whilst at the same time significantly reducing their Environmental impact.
