Huber Technology provides an innovative solution for sludge thickening with its S-Disc Sludge Thickener. The S-Disc’s compact design allows it to fit in even the tightest spaces. With only one turning disc, the unit is easy to operate and simple to maintain. The S-Disc keeps electrical, water and chemical costs low, and it is designed to accommodate fully automatic unattended operation.

The heart of the S-Disc sludge thickener is an inclined, slowly rotating filter disc that separates flocculated sludge from filtrate. A baffle plate distributes the inflow from the flocculation reactor evenly across the entire filter radius. Flexibly supported plows divide and move the sludge layer on the disc and open up furrows so water can easily drain through the filter cloth, thus enhancing the filtration effect. As the filter disc continuously rotates, a scraper pushes the thickened sludge from the disc. The filter cloth is backwashed with a spray bar.

Advantages of the Huber S-Disc:

  • Sludge volume reduction up to 90 percent.
  • Extremely favorable price for quality as 80 percent of the filter surface is permanently utilized.
  • Compact design.
  • Maximum system availability due to the long-life stainless steel filter cloth.
  • No need for lubrication.
  • Minimized coagulant agent consumption due to the preceding flocculation reactor and gentle sludge feeding.
  • Minimum control requirements.
  • Easy to operate.
  • Possibility to watch the filtration process inside the completely encapsulated unit.
  • Low noise <68 dBA.
