OUR TECHNOLOGIES / BIO-HANDLING
Solids and biosolids handling, engineered end to end
Bio-HANDLING covers the solids train, from the point material enters a building to the truck that hauls it away. We engineer with proven equipment per application, from our extensive product line into an integrated system.
Wastewater solids are some of the most difficult products to move. Dewatered biosolids cake bridges, dried biosolids carry a deflagration risk, screenings rag shafts, and grit is highly abrasive. JMS engineers our products specifically per application for the best results and long life.
Bulk solids do not behave like water. Dewatered cake bridges, dried biosolids carry a deflagration risk, and a hopper that ratholes starves everything downstream. JMS engineers the line for mass flow first, then matches conveyance, storage, and load-out to the material and the throughput.
01 · CONVEYANCE
Conveyance — Bio-BELT
Bio-BELT conveyors carry longer runs without disturbing the product, with less horsepower than screws. Bio-BELTS use troughing, flat, sidewall, and cleated configurations. Bio-PLOWS can create multiple discharge points on flat or troughing belts, adding flexibility to outloading designs.
Specify: Bio-BELT · Bio-PLOWS
02 · CONVEYANCE
Conveyance — Bio-SCREW
Moving solids reliably is the core of the line. Bio-SCREW conveyors move and elevate material to CEMA screw-conveyor standards, in shafted and shaftless forms. Shafted conveyors are a proven standard that work well conveying many products, and machined bearings ensure a smooth transfer of power. A shaftless spiral suits stringy screenings, grit, or dewatered cake, and is especially well suited for verticals: a pulling vertical requires no lower end bearing, reducing a maintenance point of failure. A pushing shaftless can also be fitted with a low-cost, effective compaction head for screenings.
Specify: Bio-SCREW (shafted · shaftless · inclined · vertical · compacting head)
03 · STORAGE
Storage — Bio-HOPPER
JMS Bio-HOPPERS are enclosed square or rectangular storage vessels that hold material between processes and feed the next stage on demand or to trucks for haul-off. Bio-HOPPERS are sized to volume and discharge rate, with mass-flow geometry and a Bio-LIVEBOTTOM or Bio-FRAME discharge engineered to prevent ratholing and keep material moving for even discharge. Bio-HOPPERS typically discharge through gates for truck loadout, or gates to pumps or conveyors.
Specify: Bio-HOPPER
04 · STORAGE
Storage — Bio-SILO
Bio-SILOS are cylindrical, shop-fabricated or site-bolted depending on diameter, and store material between processes or for loadout. Bio-SILOS are sized to usable volume and discharge rate. Bio-LIVEBOTTOM or Bio-FRAME discharge is used for wet products; Bio-ACTIVATOR is used for dry products. Dry-biosolids Bio-SILOS are engineered to meet NFPA recommendations for explosive dust in a confined space.
Specify: Bio-SILO
05 · STORAGE
Storage — Bio-BIN
Bio-BINS are open or retractable-top storage vessels of any shape. They may be used for truck receival, sized to truck volume and a discharge rate that meets load frequency, and can use a Bio-LIVEBOTTOM or Bio-FRAME discharger to feed a downstream process. Bio-BINS may also accept screenings or grit in the headworks, using a large slide gate for discharge.
Specify: Bio-BIN
06 · STORAGE LEVELING
Storage leveling — Bio-LEVEL, Bio-VSR
A vessel that fills unevenly wastes capacity and loads its structure off-center. Bio-LEVEL leveling screws and Bio-VSR rotary levelers spread incoming material across the vessel so it fills evenly and stores more in less height, which lowers the silo elevation and the structural cost that follows it.
Specify: Bio-LEVEL (leveling screw) · Bio-VSR (rotary leveler)
07 · LOADOUT & DISCHARGE
Loadout and discharge — Bio-GATE, Bio-DIVERTER
The end of the line is controlled discharge to a truck, a process, or one of several destinations. Bio-GATE slide and knife gates isolate flow between equipment, and Bio-DIVERTER chutes route material where the sequence calls for it, including metered truck load-out with dust control at the spout.
Specify: Bio-GATE (slide · knife) · Bio-DIVERTER · Solids Loadout System
08 · MEASUREMENT & CONTROLS
Measurement and controls — Bio-SCALE, Bio-SENSOR, Bio-CONTROLS
Automated handling depends on knowing how much material is where. Bio-SCALE weighs storage vessels through load cells built into the structure, Bio-SENSOR reads fill level by radar, ultrasonic, or laser per the application, and Bio-CONTROLS ties motors, gates, and sensors into automated load and unload sequencing.
Specify: Bio-SCALE · Bio-SENSOR · Bio-CONTROLS
09 · SAFETY
Safety — Bio-NITRO, Bio-DUST
Dried biosolids carry a combustible-dust deflagration hazard, and the handling system has to design for it. Bio-NITRO inerts the vessel atmosphere with nitrogen to suppress deflagration, and Bio-DUST captures airborne dust at transfer points, both engineered to the facility’s combustible-dust requirements.
Specify: Bio-NITRO (nitrogen inerting) · Bio-DUST (dust collection)
