Advanced Fine Filtration Technology
The NHD automatic leaf filter is a new type of filter, which can concentrate and filter medium. Capable of operating at various pressures (up to 1.0 MPa design pressure), it efficiently handles challenging media such as low-solid, high-viscosity, or hard-to-filter materials. With features including high automation, extended filter cloth lifespan, low operating costs, and easy maintenance, it ranks among the world’s most advanced fine filtration equipment.
Key Features
Smart Automation
PLC with touchscreen provides reliable operation control. Fully automatic running with low labor intensity and simple operation.
Efficient Sludge Concentration
The filter cake settles at the vessel bottom after cloth stripping, achieving high-concentration sludge discharge in the next cycle.
Quick Access Design
Hydraulic fast-opening device allows easy head access.
Enclosed & Eco-Friendly
Fully enclosed operation ensures long cloth life, zero leakage, and no environmental pollution.
Emergency Isolation
Isolation valves enable immediate single-element shutdown during abnormalities.
