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.

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.

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.

The patented orifice blocks remove 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 and results in more finished water. Since the orifices are tapered and oblong in shape, plugging is prevented.
