Operation Benefits and Advantages
High Capacity Continuous high production for maximum filtering capacity – wide latitude in productivity per unit area.
Low Operation Cost – minimum maintenance due to easy operation and simple control features.
Efficient Vacuum Use – Optimal hydraulic design and a perfectly seal low air leakage solution allows maximum dry cake discharge.
Excellent Filtrate Clarity – Drum Filters frequently produce solids as low as 100 PPM. Precoat designs can achieve concentrations of 10 PPM or less.
Effective Cake Washing – High purity of valuable product can be achieved with cake washing.
Flexibility – Frequency controlled drives allow high flexibility to varying feed conditions.
