Receiving Station JMS metered-end discharge receiving stations are typically loaded by truck or directly from dewatering equipment. These systems provide temporary storage of solids until the sludge can be metered into downstream equipment at a controlled rate. Most often used at the front end of dryer or incinerator operations, these systems typically include a sludge hopper and additional downstream conveyors or pumps. JMS systems are optimized to prevent plugging, bridging, and rat-holing to evenly distribute material within the hopper, fully utilizing available capacity. JMS engineers can provide assistance in sizing custom equipment for your application, taking into account angle of repose, material characteristics, and loading/discharge points of a given project. Typical Components JMS Receiving Stations can include some or all of the following equipment: Rectangular metered-end discharge hopper with live bottom screws Circular bottom discharge hopper with live bottom screws Retractable truck receiving cover for odor control Hopper load cells Shafted or shaftless screw conveyors Belt conveyors with belt scales Level sensors Slide gates Structural platforms/walkways Control panels JMS at Work Mid-Atlantic JMS had the opportunity to contribute to the largest thermal hydrolysis plant in the world, supplying a JMS Bio-HANDLING biosolids receiving station equipped with metered-end discharge. Turning a waste problem into financial opportunity, while reducing their carbon footprint was a worthwhile goal for this huge project. To achieve the control needed for the thermal hydrolysis process, bins with twelve hour holding capacity were needed. cake bin provide a means of metering sludge to the thermal processing pumps. One feeder screw feeds either pump. JMS made special accommodations in the cake bins, live bottom feeders, and slide gate valves for elevated hydraulic pressures within the process. Each component was hydro tested to withstand 12 psi and special gaskets were used in the final field welding and construction process. With the great success of this facility, it has become the prime reference for other plants considering the Thermal Hydrolysis process. Mid-Atlantic installation of Bio-HOPPER cake bins and live bottom feed. JMS 316L stainless steel cake bins with load cells and live bottom were part of the Main Process Train fed by dewatering centrifuges. Diverting slide gates above the cake bins close to divert centrifuge liquids to the drain, or open to feed solids to the cake bin storage. JMS live bottom feeders mounted on the bottom of each
Bio-Stabilization Systems Bio-stabilization systems are an effective process to meet EPA (40 CFR 503) guidelines regarding the safe treatment, beneficial use, and disposal of biosolids. Lime stabilization is specifically mentioned in the EPA regulations as a method of pathogen kill and a way to reduce the tendency of biosolids to attract disease vectors such as rodents and insects. Class A or B lime stabilized biosolids can be land applied as a fertilizer or soil conditioner. Typical Components JMS systems are optimized to allow for reduced lime volumes/costs and to prevent material bridging and plugging issues. JMS Bio-Stabilization Systems can include some or all of the following equipment: Sludge receiving hoppers with live bottoms Weigh belt conveyors Shafted or shaftless screw conveyors Pugmill mixer Lime storage silos with truck fill lines Truck load-out hopper with live bottom screws and slide gates Hopper weigh systems Level sensors Structural platforms/walkways Control panels JMS at Work The Carolinas JMS supplied an upgraded Bio-HANDLING biosolids stabilization system for a customer in the Carolinas. This plant uses lime based application to process sludge into alkaline stabilized residuals for local land applications. JMS supplied not only storage and conveyance for the biosolids, but also OSHA approved platforms and walkways over the receiving truck area. discharged onto an inclined belt conveyor and transferred to the storage area. A final reversing JMS belt conveyor allows for distribution of biosolids to either of two storage areas. JMS provided a specially designed controls system for the Carolinas project which gives the customer the ability to precisely meter the sludge and lime feeding the pugmill mixer. The ability to carefully control the process resulted in savings to the customer on lime costs and maximized the sludge to the biosolids conversion process. Carolinas installation with silos and Bio-BELT for biostabilization process. JMS played an integral role in this project, supplying sludge hoppers with live bottom screw conveyors discharging onto shaftless screw conveyors for transport to a JMS sidewall belt conveyor with load cell to measure the amount of material transferred. The destination is a new JMS pugmill mixer where lime is added from the JMS lime slio by a shafted screw conveyor. After blending, the biosolids are
Dried Biosolids Systems Sewage dust is typically an ST1 explosive class dust which means the Kst constant falls in the range of 0-200 bar-m/sec. JMS has successfully dealt with the combustion and self-heating properties of dried sewage sludge as well as meeting required NFPA (National Fire Protection Association) requirements for its transport. JMS dried biosolids storage systems act as the first line of defense preventing fire/explosions through the use of: Temperature sensors Carbon monoxide sensors to detect early signs of combustion Nitrogen blanket inerting systems Sizing equipment to allow for thermal dissipation of heat Additionally, if an explosion cannot be prevented, protective measures are provided as follows: Explosion relief venting Weak-seam covers Containment inside equipment Placement of equipment in a safe location Typical Components JMS Dried Biosolids Systems can include some or all of the following equipment: Drag chain conveyors Pneumatic conveyors Shafted or shaftless screw conveyors Storage silos Retractable truck discharge chutes Silo weigh systems Level sensors Temperature sensors Carbon monoxide sensors Nitrogen blanket systems Explosion relief venting Rotary air locks Structural platforms/walkways Control panels Coastal-Atlantic installation with silo, Bio-SCREW, Bio-GATE for dried biosolids process. JMS at Work Coastal-Atlantic JMS delivered a dried biosolids Bio-HANDLING conveying, storage, and load-out system for a project on the east coast. This renewable energy biosolids facility is designed to reduce energy consumption at the wastewater treatment plant and produce Class A biosolids. Extracted biosolids from the wastewater treatment process are transferred to the renewable energy process where it is dewatered and dried providing fuel to supplement the drying process, and dramatically reducing the amounts of material to be handled. JMS equipment receives the high temperature dried biosolids for transfer to a 40 foot tall JMS silo for off-loading to trucks. This silo is fitted with both thermocouples to strictly monitor the temperature through PLC control and a CO monitoring system. Load cells on the silo measure material for unloading through a slide gate valve and on to a JMS screw conveyor with dust collection system. Material exits via one of three discharge slide gates for equal distribution on the truck. Special accommodations were made by JMS for safety and efficient operation. A dust collection system was fitted on both the screw conveyor and each load-out spout. Spouts extend/retract as the truck load level changes to further minimize dusting. With the help of JMS, this plant has created a fully automated truck load-out facility that is monitored remotely by the SCADA system.
Truck Load-Out Station JMS bottom discharge truck load-out stations are typically loaded by conveyor, pump, or directly from dewatering equipment. These systems provide storage until the sludge can be discharged into transportation vehicles. Load-out stations generally include a sludge hopper and additional conveyors or pumps. The discharge rate of sludge into trucks is controlled by slide gates. JMS systems are optimized to prevent plugging, bridging, and rat-holing to evenly distribute material within the hopper to fully utilize available capacity. JMS engineers can provide assistance in sizing custom equipment for your application, taking into account angle of repose, material characteristics, and loading/discharge points of a given project. Typical Components JMS Truck Load-Out Stations can include some or all of the following equipment: Rectangular bottom discharge hopper with live bottom screws Circular bottom discharge hopper with live bottom screws Retractable truck receiving cover for odor control Hopper load cells Shafted or shaftless screw conveyors Belt conveyors with belt scales Level sensors Slide gates Structural platforms/walkways Control panels JMS at Work Pacific Northwest JMS designed and manufactured a Bio-HANDLING truck load-out station at a new Pacific Northwest regional wastewater treatment plant s biosolids production facility. This particular county has been safely recycling biosolids for over twenty five years. In the case of their new plant, the stabilized, dewatered biosolids are hauled off site and beneficially used with biosolids from their other area plants. classifying screw conveyor was fitted with electric actuated slide gates between the classifying and reversing conveyor. The large size of the JMS stainless steel hoppers presented a challenge to all involved. The hopper was preassembled in the JMS plant to accomplish pre-shipment testing, and to allow for the contractor s measurements and inspection. With that complete, the hoppers were disassembled for the long trip to the customer location. Once they were put in place, re-assembled and field welded, the receiving building was constructed around the equipment. Due to loading restrictions at the facility, JMS knowledge was also tapped to recommend and manufacture special pneumatic slide gates for easy control and speed in the fully automated truck loading facility. Pacific Northwest installation with Bio-SCREW, Bio-HOPPER, and Bio-GATE to truck load-out. The CH2M Hill/CDM design for the bottom discharge JMS Bio-HANDLING truck load-out system at this location included screw conveyors to receive sludge from centrifuges and transfer it to live bottom hoppers. A reversing transfer screw conveyor between the hoppers, gives the option of transferring from either centrifuge to either hopper. Each
Success Stories Cabarrus County, just up the road from the JMS headquarters, is the home of Concord and Kannapolis, NC. This thriving area is known for both its rich history and motorsports involvement. Like many populated areas, Cabarrus County struggled to find a cost effective biosolids management plan. Enter the Rocky River Regional Wastewater Plant. Being within 100 miles of over 17 large wastewater facilities gave them both a unique opportunity, and available sludge for biosolids import. JMS has supplied this plant with more than one piece of equipment over the years, including a 2001 belt conveyor and sludge bunker, still in peak operating condition. When the CH2M Hill design called for two cake bin biosolids receiving stations and transport connectors for imported biosolids, there were no second thoughts by plant personnel when JMS was awarded the Bio-HANDLING system bid. JMS live bottom hoppers with metered discharge, cake mixing bin, and shaftless screw conveyors for transport between storage bins were installed in 2013. Chad VonCannon, Assistant Engineering Director and long-time plant employee, has worked with various pieces of JMS equipment. In each case, including the new JMS cake bin receiving stations, Mr. VonCannon praises the reliability of the equipment. In his words, JMS has been a great resource for tackling issues. They come on the site to learn from the operators, listen to their needs, and act as a team member to find unique solutions. JMS has played a key role in the end result. This plant now imports biosolids from other facilities, supplementing the solids produced in the incineration process, minimizing their dependence on fuel oil, and optimizing incineration/power generation capabilities. In addition, WASCC will gain the tipping fees charged for the receipt of the imported solids.
