Water and wastewater treatment facilities have made good use of this type of conveyor for transporting dewatered biosolids, sludge, screenings or grit. A properly designed conveyance system with the ability to handle the special characteristics of sludge is critical to the effective transport of material through the process. Dewatered sludge cake can consist of wastewater plant biological sludge from the treatment of municipal wastewater, or dewatered water treatment plant sludge.
The JMS Bio-SCREW (Screw Conveyor) is easily adapted to congested locations for horizontal, inclined, or vertical conveyance. The streamlined design offers several advantages for environmental applications, including the total enclosure of materials (for odor and spillage control) and the movement of various materials from wet to dry, slow-moving to free-flowing.


Typically square or rectangular with an open top for loading purposes, our Bio-BIN employs live-bottom screw or sliding-frame technology and can also be designed for smaller volume frontend loader applications. JMS also offers retractable covers for weather protection and odor control.
Each Bio-HOPPER consists of a rectangular or square storage vessel designed explicitly to our customer’s specifications. Every component, from the quantity and size of inlets to the structural reinforcements, is carefully designed to perform for specific applications.
JMS offers three types of stainless steel storage tanks: bolted RTP (rolled, tapered panel) storage tanks, field-welded storage tanks, and shop-welded storage tanks. Additionally, since Bio-SILOs are generally located in corrosive industrial environments, our corrosion protection protocols ensure a long life expectancy. Silos can be painted in the shop to extreme corrosion protection levels or primed for on-site painting. A range of paint specifications suits different regions and environments.


Solids Receival

JMS Solids Receival Systems provide temporary storage of solids received from foreign sources. Trucks or front-end loaders deposit solids into our systems before conveyance to downstream equipment for further processing. Typically installed at ground level for ease of filling, JMS Solids Receival Systems meter solids at controlled rates through Bio-LIVEBOTTOMs, Bio-FRAMEs, Bio-SCREWs, and Bio-GATEs.

Solids Storage

JMS offers a complete line of material handling and storage solutions designed to fit precise applications. We carefully consider all aspects of an application before selecting the most appropriate components and equipment to complete all Bio-HANDLING systems.

Dry Solids

JMS dried biosolids storage systems act as the first line of defense against fire/explosions. Our rigorous product standards ensure excellent handling of dried sewage sludge, accounting for combustion and self-heating properties and meeting NFPA (National Fire Protection Association) requirements for transport and storage.

Solids Loadout

JMS Solids Loadout systems provide easy conveyance and even distribution of material into truck beds or containers. Typically fed from a Bio-HOPPER hopper, Bio-SCREW or Bio-BELT conveyor(s), or directly from dewatering equipment, JMS Solids Loadout Systems can be automated to discharge material via Bio-GATE slide gates or Bio-DIVERTER diverter valves located at multiple discharge points.
