Sludge Receival, Storage and Outloading Solutions

With hundreds of successful sludge storage installations worldwide, our systems have proven their reliability and efficiency over decades of service. Our expertise in sludge receival, storage, and outloading has made us a trusted partner for wastewater treatment facilities and various industrial applications.

Innovative Outloading Systems

We offers two primary outloading systems: live-bottom and sliding-frame. These systems can be combined with rectangular or round silos and truck reception bunkers, providing flexibility and optimized solutions for a wide range of applications.

Live-Bottom Silos

Our live-bottom silos are custom-designed for the wastewater industry, particularly for the storage, transfer, and outloading of sludge. These silos feature multiple shaftless spiral conveyors that form a rectangular bed of moving spirals, eliminating bridging or blockage of even the stickiest sludges. The large diameter, large pitch spirals are capable of high torque and fast, controllable outloading rates. The low RPM ensures that trough liners rarely need replacing. The system is simple to operate, with direct drive and few moving parts, ensuring near-zero maintenance.

Sliding-Frame Silos

The sliding-frame outloading system is an extremely efficient extraction method designed to discharge non-free flowing materials from a flat bottom silo or receival bunker. These bulk materials can often block the bottom of a silo by forming a bridge. The hydraulically driven sliding frame breaks any bridges that may form over the extraction screw and pushes or pulls the material toward the center of the silo for discharge. In round silos, the sliding-frame is built as an elliptical frame made of solid steel bars profiled to a wedge shape. This elliptical framework, with its wedge profile, pushes under the sludge in one direction and draws it toward the discharge opening in the other, allowing near-total emptying of a flat bottom silo. For rectangular silos, the sliding-frame is constructed in a rectangular “ladder” shape, transferring material from one wedge-shaped “step” of the “ladder” to the next as it oscillates back and forth

SPIROTAINER^®: Efficient Containment and Transport

The SPIROTAINER^® is an automatic self-filling containment and road transport system designed for the hygienic and automatic handling of foul or objectionable waste materials. It features autofilling capability to minimize human interaction, enhancing safety and efficiency. The SPIROTAINER^® maximizes storage volume and offers a cost-effective solution for containing and transporting materials such as screenings, grit, or sludge. This system eliminates the need for a specialized screenings building, keeping all materials fully enclosed and reducing the chances of damage caused by escaping substances

Our innovative solutions for sludge handling, including the SPIROTAINER®, sliding frame, and live bottom systems, provide efficient, reliable, and low-maintenance options for a wide range of applications. With their versatile design and high-capacity outloading, our silos are an excellent choice for any sludge storage and handling needs. As the wastewater industry continues to evolve, we remain committed to delivering cutting-edge solutions that meet the demands of modern facilities. Talk to us to find out more.
