How It Works
V-FOLD Folding Belt Filter Press
The V-FOLD is like a conveyor with filter fabric as the belt. It differs from other belt presses by using a single belt made from conventional filter fabrics with a reinforced centre-line. As it moves slowly forward the belt folds along the centre to form a ???V-shaped• cavity that can hold feed slurry.
Initial dewatering is by gravity draining in the feed cavity. Sludge is then trapped between the sides of the belt and squeezed as it passes around a series of vertical rollers where pressure and shear form a filter cake.
Forgiving Nature
Industries in the small to medium size range often have variable wastewater quality.
The V-FOLD is “forgiving” of variations in feed composition that can upset conventional dewatering equipment. The feed cavity simply fills a little more or less depending on slurry conditioning. It can make the difference between frequent Operator intervention, and leaving the filter to run almost unattended.
Performance
The V-FOLD filter can dewater a wide range of feed materials. Two sizes are available, each with various options to suit Customer needs. Like all dewatering devices, V-FOLD performance depends on the feed slurry. They are operating with slurries from approximately 1% DS to 10% DS, and have feed rates up to 3,000 litre/hour.
