Proven in Alumina.
Trusted Across Industries.
NHD disc filters have been successfully deployed in the alumina industry for the separation of aluminum hydroxide from caustic solutions. Beyond this primary application, these filters are also gaining increasing adoption across multiple industries including metallurgy, environmental protection, ore washing, and paper manufacturing.
Through multiple rounds of technological upgrades and innovations in recent years, NHD disc filters have now reached a mature stage with increasingly outstanding overall performance. We have effectively resolved common issues such as material leakage, spillage, dripping, and seepage that occurred in earlier filter models. Concurrently, we have consistently focused on improving both the aesthetic design and operational ergonomics of the equipment, driving its continuous advancement toward cleaner operation, higher automation, and international standards.
Large Filter Disc Design
Large disc diameter maximizes contact area with the medium.
High Efficiency & Capacity
Large processing capacity with high operational efficiency.
Segmented filter discs
Specially redesigned liquor pipes and valve plates ensure rapid filtrate flow.
Space & Cost Savings
Smaller occupied area per filtering unit reduces construction costs.
