3DP Model Belt Press Dewatering Equipment

Designed with unique features to provide higher discharge cake solids at higher feed flow rates.  The 3DP is a rugged, durable machine that will provide years of reliable service.

Features:

  • Highest Capacity of any Belt Press due to:
    • Independent Gravity Zone Drive
    • Curved Wedge
    • Paddle Wheel/Overflow Weir Distributor
  • Performance Exceeding Centrifuge due to:
    • Increased Thickening in the Independent Gravity Zone
    • More Time Under Pressure
    • Eliminates Cake Rewetting with Vertical Arrangement
    • No Platform or Stairs Required
    • Reduced Conveyor Length
    • Better Access for Maintenance
  • Longer Bearing Life due to:
    • Machined Bearing Mounting
    • Strong Tubular Steel Frame
    • Less Corrosion due to Open Frame Construction
    • Thickening/Dewatering in One Unit, Dual Mode

DSP Screw Press Dewatering Equipment

BDP developed this screw press specifically for Biosolids dewatering to provide high capacity, excellent solids capture, in a fully enclosed system with automated simple operation.

Features:

  • Independent Pre-Thickening with Rotary Drum Concentrator
  • Slotted Screen: higher open area and smaller opening for improved capture, reduced plugging
  • Filtrate Recycle/Polishing: produces solids capture over 95%
  • Replaceable Flight brushed without removing screw auger
  • Tapered Screw: Reduces Distance for Filtrate Flow for increased capacity, less rotational force on material – Less slippage = increased conveyance
  • Discharge Pressure Plate: Adjustable pressure on discharge cone maximized cake solids
  • Oscillating Shower System: Programmable intermittent operation reduces water requirement

Rotary Drum Thickener — Sludge Thickening Equipment

Superior Sludge Thickening

Unique design provides a viable option to a Gravity Belt Thickener with the following advantages: a smaller footprint, unattended operation, lower investment, and maintenance costs. Performance is similar.

Features:

Low Cost Screen Construction:
Uses filter cloth instead of perforated plate or wedge wire

Large Effective Filtration Area

Variable Drum Speed Drive
Allows control of slurry depth inside the drum maximizing thickening performance

Center Shaft / Bearing design:
Keeps bearings from being exposed to process fluids

Gravity Belt Thickener Sludge Thickening Equipment

The GBT™ is used to thicken primary or secondary sludge prior to centrifuge or digestion processes. High unit capacity per floor space

Features:

Venturi Mixer:
The adjustable counter-weighted baffle allows for efficient optimization of slurry flocculation and shortened drainage time

Feed Distribution:
The up-flow smooth, weir design provides uniform distribution of slurry across entire width of the belt

Gravity Deck:
Large filtration area provides high efficiency thickening and cost effective chemical utilization

Furrowing Plows:
The combination Foil Doctor and adjustable angle plows provide twice the liquid removal
