Hoseless Sludge Collector

MRI Hoseless Cable-VacTM Sludge Collector features a floor-hugging, telescoping sludge removal pipe that extends the full length of the basin, eliminating the need for hoses and the problems associated with suction sludge collectors. It is the latest technology in sludge removal.

Low-Profile Hoseless Cable-Vac™ by MRI

Hoseless Sludge Collector Proven in
Hundreds of Installations

Developed in 2002, the MRI Hoseless Cable-VacTM Sludge Collector
removes settled solids throughout the basin, even from the final 2′ at
the end wall typically left un-collected by other sludge collectors.

Hoseless Callout
The Hoseless Cable-Vac™ does not require guide rails. Patented end scrapers, flow balancing ring, and orifice blocks remove maximum sludge.

Now with over 300 installations, the hoseless technology has proven to be the most reliable suction sludge collector available.

Designed for use with plate settlers, tube settlers, and in open basins, the MRI system is preferred by all major engineering firms. MRI has been manufacturing sludge collectors since 1980.

Performance Advantages

MRI Hoseless Cable-VacTM Sludge Collector’s proven design:

Hoseless Callout 2
Designed for precision, the patented flow balancing ring assures even flow control front to back.
  • Increases solids removal and overcomes problems found with other sludge collectors
  • Eliminates the problematic flexible sludge hose, including sludge hose hang-ups and priming
  • Eliminates the guide rail and and enables quick, simple installation
  • Removes sludge wall-to-wall, utilizing scrapers attached to header pipes to eliminate sludge settled in the final 2’ of the basin wall
  • Ensures even flow-distribution in any length basin with the patented Flow Control Device located inside the body of the Hoseless Cable-VacTM
  • Provides 230 VAC drives, the strongest available on any suction sludge collector
  • Offers custom-built controls designed to meet specific treatment plant needs
  • Includes patented orifice blocks, which remove settled solids at higher percent solids than the traditional hole in the bottom of a pipe.

MRI's Exclusive Tandem Collectors With MRI’s tandem collection design*, the incoming flow enters tangentially to the bottom of each sludge collector, causing the internal flow to travel in a spiral toward the center outlet. This creates a uniform, organized flow pattern that increases sludge removal and prevents clogging.

Conventional Sludge Collectors In conventional sludge collectors, the incoming flow enters at the bottom and continues upward, perpendicular to the internal flow, which is moving laterally toward the center outlet. This causes the two flows to collide at the orifices, decreasing sludge removal.

Key Features Only from MRI Hoseless Cable-VacTM Sludge Collector

Designed to operate underneath plate settlers and tube settlers, the hoseless system works equally well in open basins.

Patented end-scrapers clean completely to the end walls, eliminating the solids build-up found with other sludge collectors.

Patented Flow Balancing Ring ensures equal flow from each header pipe for units greater than 300′ long. The flow is then discharged at the end of the basin or run.

Patented Orifice Blocks provide higher percent solids removal than other suction systems, which results in less wasted water and produces more finished water.

Innovative Tandem Collectors Maximize Efficiency

The patented “orifice blocks” remove the settled solids from in front of the header pipes as the unit moves forward. This eliminates the load of the header pipes pushing through the settled solids.

As a result, the Hoseless units remove the settled solids on the outbound trip and idle back, with no suction, on the return trip. The higher percent solids removal means less water is wasted which results in more finished water.

Since the orifices are tapered and oblong in shape, plugging is prevented.
