Premium hydraulic filter press systems engineered to execute rapid cycle times, high dry cake density, and optimal cake release in harsh environments.
Namibia, one of the most arid nations in Sub-Saharan Africa, faces a complex intersection of booming industrial growth and severe water scarcity. The country's economy is strongly anchored by its extractive mining sector, which is a global powerhouse in the production of uranium, copper, diamonds, zinc, and gold. However, the mineral processing methods traditionally used in these operations require enormous quantities of water—a resource that is increasingly scarce and strictly regulated under Namibia’s Environmental Management Act 7 of 2007.
In this context, industrial dewatering has evolved from a simple disposal requirement into a critical driver of operational profitability and compliance. Wet tailings dams present significant environmental liabilities, including risk of collapse, high evaporation losses, and groundwater contamination. As a result, major mining operators in the Erongo, Kunene, and Otjozondjupa regions are adopting dry-stacking tailings management using heavy-duty hydraulic filter presses.
"By transitioning from traditional tailings ponds to automated hydraulic chamber filter presses, mining installations in arid regions like the Namib Desert can recover up to 95% of process water for immediate reuse, ensuring sustainable operations while reducing raw water consumption costs."
Modern hydraulic filter presses apply up to 25 MPa of closing pressure to compact slurry, forcing the liquid phase through specialized filter fabrics while forming high-density solid cakes with minimal moisture content. This dry cake can then be safely backfilled or stacked, completely eliminating the need for vast tailings dams.

Uranium and Acid-Leached Slurry Filtration (Erongo Region): Namibia holds some of the world's largest uranium deposits, notably the Rössing, Husab, and Langer Heinrich mines. The processing of uranium ore involves intense sulfuric acid leaching, resulting in highly acidic, abrasive slurries. Our customized hydraulic filter presses are engineered with corrosion-proof polypropylene plates and acid-resistant filter fabrics, ensuring reliable cake wash phases and high throughput under low pH conditions.
Municipal Wastewater Reclamation (Central Windhoek): The city of Windhoek is a pioneer in direct potable reclamation. Effective sludge dewatering is vital to ensure maximum water volume is returned to advanced water purification plants. Jovios automatic chamber presses produce high-dry-solids cakes, minimizing haulage and disposal costs while optimizing water yield.
Agricultural Agro-processing & Oil Extraction (Northern Regions): In the Kavango and Zambezi regions, the expansion of agro-processing has driven demand for high-efficiency vegetable oil extraction (sesame, mustard, and shea butter) and cassava starch dewatering. Specialized high-pressure hydraulic presses ensure hygienic, high-yield food-grade separation.
The global filtration market is undergoing a major shift driven by ESG (Environmental, Social, and Governance) mandates and stricter environmental regulations. Key trends include:
