2 Since being established in 1962, Jim Myers & Sons, Inc. (JMS) has grown continually and today is recognized as one of the nation s leading designers and manufacturers of water and wastewater treatment equipment and systems. We have reached this point by incorporating equal parts innovation, quality and reliability into every component bearing the JMS name. We maintain that leadership position through one of the most comprehensive, solution-driven product offerings available. Proven Process Performance It is not possible to sum up in a few words what has taken better than half a century to achieve, but these three come the closest. Our Bio-SCREW (Screw Conveyor System) design is already proven in applications throughout the U.S. and abroad. JMS in-depth knowledge of both the water and wastewater treatment markets allows us to fully understand your process and provide solutions like the Bio-SCREW, solutions designed with operational efficiency in mind. Like all JMS products, our Bio-SCREW offers an unsurpassed level of performance geared around the longest possible component life and the lowest maintenance demands of any comparable system. Just three words: Proven, Process, Performance, speak volumes. JMS has the answers you want, the solutions you need, and the support you deserve. Utilizing the latest software for BIM-compliant mechanical and structural design with commercial and proprietary analysis programs, our professional engineering staff makes concepts reality by providing solutions to complex problems. Bio-SCREW Installation in Sacramento, CA Positive Progress Screw technology has a long history of usefulness. Screw conveyors are currently used in many industries as they represent one of the most flexible bulk material conveyance methods available. Simple in design, the conveyor screw initiates a smooth, continuous forward movement of material. Both shafted and shaftless screw conveyors are used in the municipal water and wastewater industries to convey dewatered biosolids, sludge, screenings or grit. Screw conveyors are compact in design, and are easily adapted to congested locations for conveyance of materials in the horizontal, inclined, or vertical directions. They offer several advantages for environmental applications such as total enclosure of materials for odor and spillage control, and the ability to handle a wide variety of materials from wet to dry, and slow-moving to free-flowing. True to our roots, our 72,000 sq. ft. Charlotte facility is the site for all fabrication, manufacturing, machining, and testing. There, the JMS commitment to excellence, a part of our DNA, manifests itself every day with the promise to continue for generations to come. Conveyor Analysis Software Screw conveyors are available in a variety of materials of construction. The ability to have multiple entry and discharge points and many options for flow control often make this type of conveyor a key component of larger material handling systems.

3 Why Use a Screw? JMS is one of the largest and most established suppliers of screw conveyors for municipal and large industrial applications in North America. We use our extensive knowledge of conveyors and systems to provide custom solutions that can save dollars and maximize operational efficiency. JMS Bio-SCREW conveyors are manufactured to accepted CEMA standards, taking advantage of JMS half century of design and manufacturing experience. JMS can design shafted or shaftless conveyors in multiple configurations to meet the needs of your process, and provide heat tracing and insulation if desired. Using the latest in materials and manufacturing technology, hundreds of JMS Bio-SCREW conveyors are still in operation. Advantages: Bio-SCREW Shafted and shaftless designs available in several configurations and live bottom Complete enclosure during conveyance eliminates spilling and odors, so less housekeeping is required Perfect for congested locations Wide range of capabilities, with multiple inlets and discharges as needed Can handle high temperature, abrasive, and sticky materials Wide capacity range, and can be used to mix or meter materials Special safety features Advantages: JMS Professional Engineers on staff Integrated solutions provider Use of Conveyor Analysis Design Software for conveyors of most any length, geometry, or drive configuration CEMA manufacturer, JMS high level of CEMA involvement helps set standards for the future Project management expertise Experienced service personnel and OEM replacement parts available Longevity with hundreds of conveyors currently in service Horizontal Horizontal to Inclined Center Pivot Compacting Head Inclined Submerged Screw Tail Pivot Truck Load-Out

4 Shafted Screw Conveyors Shaftless Screw Conveyors Covers Numerous cover hold down mechanisms are available ranging from bolted to spring and toggle clamps A full range of options allows JMS to configure equipment to meet your specific needs End Seal Assembly Seal assembly prevents unwanted leakage at the shaft-trough interface JMS has extensive experience in leak prevention and can assist you in specifying the best seal arrangement for your application Shafted Screw A robust versatile option that can handle a variety of highly abrasive and viscous materials. The best choice for systems that need reversing capabilities. Shaftless Screw This design eliminates hanger bearings. Spirals are formed from nickel-alloy steel with high hardness providing a combination of corrosion and abrasion resistance. Zero Speed Switch Protects equipment and process Contacting and non-contacting types available Increase process reliability, and lower maintenance costs CEMA 226 Hanger Bearing Designed for flush mounting inside the trough, this configuration promotes contaminant-proof operation and reduces the obstruction of material flow in high capacity conveyors. Drive Assembly Standoff bracket keeps conveyed material from entering the gearbox Upgraded for heavy duty operation, and suitable for wash-down duty Liners Specialty ultra-high molecular weight two color liners provide a visual indication of wear. Premium blends and abrasion resistant wear bars can also be used to extend working life. JMS Flexible Hanger Bearing This special JMS stainless steel flexible element accommodates misalignment of the shaft and has a longer service life than a standard CEMA 226 journal bearing. Bio-GATE (Slide Gate) Used with screw conveyors that have multiple discharge points Manufactured from stainless steel Manual handwheel or an electric, pneumatic, or hydraulic actuator Bio-VALVE (Diverter Valve) Consists of 2-way or 3-way diverter valve for solid materials Manual chain wheel, handwheel, or an electric, pneumatic, or hydraulic actuator available End to End Since no end bearing is required, two shaftless conveyors can be connected end to end, reducing required elevation and simplifying transfers.

5 6 Tallahassee, FL is nestled in the rolling hills of northwest Florida. This area is the location of the Wakulla Springs, one of the world s largest freshwater springs. The shallow aquifer is vulnerable to pollution including stormwater runoff and nitrates from wastewater treatment. The city of Tallahassee s main wastewater treatment plant, Thomas P. Smith WRF, is located near the springs. Success Stories In the early 2000s the city began a study to determine how to improve the quality of reuse water and to protect the water quality of Wakulla Springs. Under the guidance of engineering giant Hazen and Sawyer a plan was developed for upgrading the system. As a part of the process, biosolids are separated from the liquid and dried for eventual use as a Class A Biosolid. Conveyance of biosolids within the dewatered sludge building and to the dryer building is an important part of the process. For the project, six JMS Bio-SCREW conveyors of various lengths and configurations were purchased. After three years of operation, Warren Shepherd, a long-time manager of the Biosolids area, reports that all conveyors have been running full-time without issues and that he could not be more pleased with the equipment. System Integration In addition to Bio-SCREW, JMS expertise extends to a host of other products and systems listed at right. Having such a broad and varied range of experience means your water and wastewater needs, whether individual component or full system, are understood. Optimized efficiency and process performance are yours for the asking. Contact JMS today.
