Pulse Discharge Candle Filter
A state-of-the art-solution for high quality filtration. The Twin Process Filtration Pulse Discharge Candle ( PDC ) Filter is a high-tech filter system, consisting of vertically positioned filter candles in a vertical tank. The filter candles can be supplied in polypropylene or PVDF. The filter medium that is used to cover the filter candles can be chosen such that a clear filtrate is instantly obtained. The cake can be discharged in solid or concentrated slurry form.
The candles are installed in several manifolds having individual filtrate outlet. The filter medium that is used to cover the filter candles can be chosen such that a clear filtrate is instantly obtained.
Filtration
The liquid to be filtered enters the vessel and flows from the out side to the inside through the filter cartridge. The filtrate flows down to the bottom of the candle and rises through the central tube in the outlet manifold. The particles are collected on the outside of the filter cloth and form a regular filter cake.
Cake Discharge
After drying the filter cake the cleaning is done by a Back Wash or a Back Pulse with air or gas. The back pressure blows up the filter cloth and brings the filter cloth in the original circumference. The pulsating back pressure opens the mesh of the cloth resulting in a very thorough cleaning. Because the filter candles are positioned on separate manifolds, they can be cleaned one manifold at a time. This decreases the quantity of air or inert gas required, and ensures that the cake is evenly discharged.
