PRESSURE FILTERS

Tecniplant has a huge expertise in the design, engineering and construction of Pressure Candle Filters and Pressure Leaf Filters, both Horizontal and Vertical models.
The Filter is composed of a pressure tank containing the filtering elements and the washing device or dry cake removal system.
The filtering elements are vertically mounted cloth covered plates in Stainless Steel/Titanium/PVC/PE/PP (so called leaves) or special candles (made in plastic materials or stainless steel).

  • High operational flexibility
  • Easy maintenance and low related costs
  • Continuously operation with operating and stand-by unit philosophy
  • Steam cleaning available
  • Construction in a wide range of sizes
  • Automatic washing system
  • Vegetable Oil
  • NaCl and KCl Brine
  • Amine MEA (Monoethanolamine)
  • Hypochlorite
  • Catalyst Recovery
  • Liquid Sulphur
  • Biodiesel
  • Solvents
  • Zinc and Manganese Sulphate
  • DEA (Diethanolamine)
  • Sea Water

The filter elements are all connected to a collector.
The filtration cycle starts and the differential pressure increases as the impurities adhere to the external surface of the filtering elements. When they are saturated the differential pressure value reaches the maximum set point and the filtration stops. The regeneration cycle starts. The cake is drained through the outlet flanged connection located on the bottom. The filter is then ready for a new cycle. The plant can be made up with more than one filter in order to carry out a continuous and balanced operation, combining production and regeneration phases, ensuring constant outlet. The systems range from manual to fully automated, depending on the combination of the filtration units.
