Screw in Tank

The CSS and SSS screw screens, available with or without a compactor, are specialized equipment designed for solid-liquid separation. They effectively combine two critical processes: filtration and compacting. These screens are equipped with a basket, which can be made from either perforated sheet or wedge wire, serving as a robust filter. This is followed by a tubular transport section, culminating in a compacting and dewatering module that can be outfitted with either a chute or a bagging system.

In these systems, screenings are efficiently conveyed by a shaftless screw, which is equipped with bolted plastic brushes in the screen basket section to maintain cleanliness. The process leads to the compacting and dewatering section, where there is a substantial reduction in both volume and weight of the material, achieving reductions of up to 40%.

Designed for adaptability, these machines are typically installed inside a channel that suits their width. The CSS or SSS screens are ideal for channels up to 850 mm wide. They are available in various material combinations, including different grades of stainless steel (304, 316, or Duplex) and high-strength carbon steel, with the spiral component also available in these materials.

The basic machine configuration can be enhanced with several optional features, including additional or custom-made discharge chutes and washing systems for the basket and/or transport section. To address odor issues, the standard compacting module includes a washing system, which can be operated manually or through a solenoid valve.

Key advantages of the CSS and SSS screw screens include:

• High operational efficiency.
• Simplicity in design and function.
• Extremely straightforward installation.
• Very simple maintenance requirements.

For most installations and operational scenarios, maintenance primarily involves replacing brushes every two years. This process is made simpler by the unique auxiliary pivoting system, allowing easy on-site maintenance, even by personnel without specialized training.

Additionally, these units can be equipped with a control panel upon request, available in either electromechanical or PLC-controlled formats, to meet various operational preferences and requirements.
