Low-footprint RO system

The MegaMagnum water treatment system uses 18-inch-diameter, spiral-wound RO elements, which reduce the cost, footprint, and installation time. A single 18×61-inch element contains 2800 square feet of membrane surface area. The pre-engineered, packaged product is quick to set up and start. Four configurations, with nominal flow capacity ranging from 0.5 to 20 mgd, are offered. Standard package includes flowmeters, pressure transmitters, conductivity meter, variable frequency drive, and interface with touchscreen, data trending, and Ethernet access. Options include antiscalant dosing, acid dosing, chlorine monitoring, and clean-in-place features. Koch Membrane Systems. www.pwmag.com/05may11.

Graffiti-resistant coating

Series 626 Dur A Pell GS is a silicone rubber-based barrier that prevents various paints and markers from adhering to public buildings, bridges, sound walls, highways, roadside structures, water tanks, and other structures. In addition to resisting graffiti, the water-resistant properties of the product help it minimizing damage resulting from weather and moisture penetration, and to resist freeze/thaw damage. The coating is transparent, dries to a clear finish without altering the substrate's appearance, and is easy to apply. Chemprobe Coating Systems. www.pwmag.com/05may12.

Added security truck boxes

Weather Guard diamond tread aluminum truck boxes feature a lock that retracts for added tamper resistance. The retracting button allows contractors to visually determine lock status from a distance. Additionally, an internal torque ring eliminates many common keyhole break-ins. The cover opens to a 90-degree angle for easy loading and unloading, and the box is completely weather sealed underneath the lid. The boxes are available in five styles in either a clear or black Armor-Tuf powder coat finish. Knaack Manufacturing Co. www.pwmag.com/05may13.

Wide-area mower

The WalkAbout wide-area mower has engines that provide smooth, quiet operation; the 48-inch cut model has an 18-hp twin engine, and the 36-cut mower has a single 15-hp engine. The five-speed manual transmission provides reliable power transfer. Other features include rugged, nine-spline PTO coupler, dual drive belts, and heavy-gauge welded steel decks that produce superb cutting results and bagging performance. A mulch kit and side-mounted grass catcher are optional. Dixon Industries Inc. www.pwmag.com/05may14.

Total station with GPS

The SmartStation integrates GPS and total-station capabilities into one compact package, with common software, database, storage media, and user interface. The combination of the features eliminates the need for additional cables, batteries, or data loggers. To use, set the station up at the desired location, then press the button; the product automatically determines its position accurately within a few seconds. It is ideal for topographic surveys in remote areas, legal boundary surveys, utility surveys, and stakeout on construction sites. Leica Geosystems. www.pwmag.com/05may 15.

Stormwater filtration tubes

Terra-Tubes are fiber filtration devices used to trap, filter, and treat sediment-laden runoff while reducing hydraulic energy. The products are composed of wood fibers, manmade fibers, and polymers, which are encased in heavy-duty knitted tubes. The tubes are suitable for a range of applications, including slope interruption devices, channel flow checks, drain inlet protection, and perimeter sediment control. They can be used to complement other methods, including hydraulically applied products, erosion-control blankets, and turf reinforcement mats. Profile Products LLC. www.pwmag.com/05may16.

Pavement sealant

E-Krete is a polymer composite micro overlay that extends the useful life of asphalt surfaces by reducing the need for resurfacing, sealing, and replacement. It eliminates the generation and release of toxic materials such as polycyclic aromatic hydrocarbons, coal-tar materials, and hazardous solvents. The product minimizes the impact on the environment and crews using it while providing superior protection to the pavement. Polycon Systems Inc. www.pwmag.com/05may17.

Low-emissions landfill compactor

The 836H landfill compactor features a low-emissions engine, new cooling system, and other enhancements designed to make it easier to operate and service. The engine delivers 498 net hp at 1800 rpm, and it operates cleanly, quietly, and efficiently. The blade is automatically lowered when the machine is shifted forward and raised in reverse, improving comfort and productivity. A wide variety of options are available, including a Semi U blade, high-intensity discharge lights, and the Product Link system, which uses satellite technology and the Internet to monitor the machine's location, service meter hour, and product health information.

Large-pipeline descalers

The ScaleBlaster line of electronic descalers has been broadened with seven new models. Suitable for descaling large-diameter pipeline, downstream pipelines, and equipment (valves, pumps, boilers, heat exchangers, cooling towers, etc.), the product handles standard diameters of non-ferrous pipe from 12 to 40 inches, and ferrous pipe from 4 to 26 inches. The product simultaneously prevents scale from accumulating and removes existing scale from the pipe and equipment. The process provides an effective, cost-saving, and non-polluting alternative to chemical descaling. Clear-Water Enviro Technologies Inc. www.pwmag.com/05may19.

Hydraulic hammer

The Arrow Hammer 1350 compacts and tamps backfill with adjustable impact up to 13,000 foot/pounds—or at a fraction of that force when it's necessary to protect what's underground. It also breaks, cuts, and scores concrete, rock, and asphalt into sizes suitable for excavation, recovery, or cracking and seating. The pneumatic-tired, mobile hydraulic hammer operates both on and off paved surfaces, with features including mechanical or electronic stroke control, a mechanical back-up alarm, and a pivoting mast for maximum impact on uneven surfaces.
