Gravity Belt Thickner Information
The EMO Gravity Belt Thickener is engineered for the continuous mechanical thickening of municipal and industrial sludge, reducing sludge volume by a factor of four or more. With its low energy and polymer consumption, stainless steel construction, and minimal maintenance requirements, the GBT is a reliable and efficient solution for high-capacity sludge treatment operations.
Key Applications:
-
Final Thickening Stage: Increases sludge dry solids (DS) concentration to 6–8%, effectively replacing conventional static thickeners or flotation systems.
-
Pre-Dewatering: Functions in-line with a Belt Filter Press to enhance dewatering efficiency and performance.
-
Anaerobic Digestion Optimization: Reduces sludge volume prior to digestion, minimizing digester size and associated infrastructure costs.
Designed for installations processing up to 200 m³/h of raw sludge per unit, the EMO GBT is ideal for large-scale treatment plants requiring high performance under demanding conditions.

Areas of use
The two-belt belt filter press is a tried and trusted method for dewatering sludge (primary and secondary). As we all know that one good belt filter press cannot out perform another good belt filter press in terms of Dry Solids. The dewatering ability is more closely related to the type of sludge and the polymer used. Having said that, the EMO design offers some benefits which we believe offer a competitive advantage.
• The Gravity drainage section is always a separate machine for low DS concentrations (typically used when pumped directly from the biological reactors at 4-5g/l). This allows a larger aperture to be used in that machine.
• Entry to the EMO belt filter press is at the bottom of the machine.
• The largest percentage of water is removed by the first pressing roller, and this ensures that water is at the bottom of the machine and is discharged directly to the outlet.
• Bottom entry also allows for a flatter machine which in turn ensure that platforms next to the equipment are not required for inspection and maintenance.
• All rollers (but one) are the same diameter, which ensures emergency spare parts required on site are reduced to only one roller and one set of bearings. product.
• Discharging of dried sludge is also thus at the top of the machine, which allows for easy installation of a screw conveyor below the discharge. Dewatered Sludge transportation from a low level is troublesome due to the sticky thick nature of the
Furthermore the EMO Belt Filter Press is manufactured from stainless steel and the design takes into consideration fitting a standard sea freight container (even for the largest model) to minimise transportation costs.
