Use this filter in battery-chemical applications

| By Mary Page Bailey

The compact DM1000 polishing filter (photo) is particularly suitable for removing and recovering organic compounds and solids in small-stream feeds in battery chemicals processes. Thanks to its modular design, the filter is easy to expand also for larger process flows. The DM1000 can be used as a traditional electrolyte filter in the extraction processes, as well as for feed-flow purification before crystallization in metal crystallization processes. A lower pumping pressure means that less energy is consumed in operation, and the backwash uses filtrated process liquid, which reduces water consumption. Filters can be packed and transported in standard containers, and installation is simplified by the filter’s skid-mounted assembly. — Metso Outotec Corp., Helsinki Finland
