Wastewater treatment screw press XSplit®

for sludge dewatering

Overview
The XSplit® press screw separator from Vogelsang combines the classic press-screw separation principle with a redesigned technical concept. The drive is arranged on the solid outlet side, providing a cost-efficient layout and practical advantages. Separation increases the dry matter content of the solid fraction while producing a thin liquid phase that is easier to handle and store.

Key benefits

• Dry matter content up to 40% possible
• Adjustable pressing area to vary dry matter output
• Easy access to sieve and screw for fast maintenance
• Reliable plug formation without auxiliary agents
• High-quality elastomer sealing disc for consistent separation

Did you know?
Separating digestate or liquid manure reduces floating and sinking layers in storage, produces solids easier to transport or use as bedding, and leaves a thin liquid phase that simplifies land application and reduces digester viscosity.

Models

• XSplit® — High throughput design: Allows high flow rates (up to 50 m³/h) and dry matter contents up to 40%.
• XSplit® Compact — Space-saving unit for agriculture and biogas: Separator, pump and control can form a single compact unit. Forklift pockets for easy transport. Optional feed pump or feed-and-discharge pump to convey the liquid fraction to storage or tanker.

Features

• Flexible inlet and filtrate nozzle: Rotatable in 90° increments and mountable top or bottom for on-site adaptability (connector size 6 in).
• Screw: Stainless steel screw, specially armored for durability; integrated fiber pockets for self-cleaning.
• Rubber disc with sealing effect: Wear-resistant elastomer closure disc ensures automatic plug formation without additives.
• Innovative drive arrangement: Motor on the solid outlet side with no contact to the liquid; conveying and separation toward the drive without additional radial shaft seal.
• Adjustable pressing area: Length adjustable via threaded spindle; longer pressing area increases dry matter of solids.
• Flexible sieves: Sieve basket with three individually replaceable sieve elements for optimal service and medium adaptation.
• QuickService: Generous end cover for easy access to sieve and screw; four 6 in cleaning ports for rapid interior access and maintenance.
• Feed pump (XSplit Compact): Powerful feed pump draws manure or digestate from pits and feeds the separator; liquid phase returns to storage by gravity or can be pumped with the feed-and-discharge option.

Options

• Fixed frame: Stud frame to elevate the XSplit; base frame can accommodate pumps and optional shredder to reduce on-site installation work.
• Lift frame Basic: Compact pre-assembled unit with pump and optional shredder; hydraulic elevation for quick relocation.
• Lift frame Pro: Trailer-mounted complete solution, assembled with hydraulics and controller; larger ejection height for direct filling of high trailers.
• Controls: From manual operation to touch-panel controls with intuitive UI, configurable to customer needs.
• Feed and discharge pump (XSplit Compact): Compact feed-and-discharge pump that feeds separator and pumps liquid phase back to storage or tanker.

Application areas

• Agricultural technology: On-farm separation to optimise nutrient management and handling.
• Biogas: Improved plant operation and easier feedstock handling.
• Other sectors requiring solids/liquids separation where reduced maintenance and high dry-matter output are beneficial.

Technical specifications

• Maximum dry matter (solid fraction): up to 40%
• Typical maximum throughput: up to 50 m³/h (depending on medium and application)
• Connector size (inlet/filtrate nozzle): 6 in (nozzles rotatable in 90° increments)
• Sieve basket: three individually replaceable sieve elements
• Cleaning access: generous end cover + four 6 in cleaning ports
• Screw material: stainless steel, specially armored with fiber pockets for self-cleaning
• Closure disc: wear-resistant elastomer sealing disc for automatic plug formation
• Drive arrangement: motor located on solid outlet side; no direct contact with liquid; no additional radial shaft seal required
• Adjustable pressing area: length adjustable via threaded spindle to influence dry matter output
• Optional feed pump (XSplit Compact): feeds from pits/storages; liquid returns by gravity or can be pumped with feed-and-discharge option
