High-velocities magmeter
Marsh-McBirney recently introduced the Multi-MagT magmeter, an addition to its existing Multi-Mag product line. The new insertable multi-electrode sensor is ideal for pipe sizes 36" - 120". An array of electromagnetic sensors are strategically located on the insertable probe that spans the entire pipe diameter. The sensors detect and compensate for shifting profiles. The streamlined sensor shape minimizes flow disturbances, thus providing minimal pressure drop. The meter has proven itself in difficult flow conditions such as shifting profiles, low flows, wide flow ranges, and bend/elbow installations. The meter offers accuracies better than 1% of reading and comes with a standard five-year warranty.

Tablet chlorination system
PPG's Accu-Tab System consists of 3" calcium hypochlorite tablets with 65% available chlorine used in the patented erosion chlorinator. The chlorinators have no moving parts and no small openings to clog - eliminating the need for metering pumps. A portion of the process water, whether potable or wastewater, is diverted through the chlorinator. The water flow erodes the tablet, with the amount of chlorination being controlled by the inlet water flow. The chlorinated water is then returned and mixed in with the process stream. This system is an alternative to chlorine gas cylinders and sodium hypochlorite for sanitizing water systems.

DOC removal
A new NSF-approved continuous magnetic ion exchange process from Orica Watercare is designed to remove dissolved organic carbon (DOC) from drinking water. The new system uses the patented high capacity MIEX® resin. It removes DOC at the front end of a water treatment plant in a stirred contactor, much like a flash mixer in a conventional water treatment plant. The significantly smaller resin beads provide maximum surface area and allow rapid DOC adsorption kinetics. A magnetic component is dispersed within the resin particle structure so that, when passed to a settler, the fine resin beads rapidly agglomerate into larger, fast-settling particles.

Flow recorder
The portable, battery-powered Meter-Master Model 100EL Flow Recorder converts a meter's magnetic drive signal to a digital output that is stored for later downloading. It is compatible with almost all water meters, small enough to fit inside a residential meter box and easy to set up. The unit uses a patented sensor to pick up the magnetic pulses generated by a meter's drive magnets. No electrical or mechanical connection or adapter is required for most meters (Gear-driven meters, Hersey MHR meters, and Sensus compound meters require available adapters). Meter-Master software for Windows provides a variety of report and graph options.

Membrane filter press
Rittershaus and Blecher membrane filter systems, offered by Baker Process, add new dimensions to the operability and performance of the proven chamber filter press technology. They feature shorter cycle times, with increased capacity for existing filter presses or lower investment for new facilities. They also produce drier cake solids, for lower transport and disposal costs for landfill or lower thermal energy costs when drying or incinerating sludge product. The systems have a reduced need for conditioning chemicals, so specific cake solids objectives are possible with significantly lower conditioning chemical requirements.

Pressure pipe
Ultra-Blue Class 150 PVC Molecular Oriented Pressure Pipe with a cast iron OD meets AWWA Standard C909. The pipe attains a high strength by re-orienting the molecular structure in the hoop direction. Ultra-Blue is lighter and tougher than conventional PVC, leading to lower installation costs. The non-corrosive pipe has a larger inside diameter than ductile iron or conventional PVC, providing greater flow capacity and lower head loss. One of the safest and easiest pipes to tap, it won't split from end to end. Its uses include potable water systems, sewer force mains, and water transmission and distribution lines.

Folded plate underdrain
Enviroquip offers a folded plate underdrain air scour system that features an improved media-retaining design. The underdrain eliminates the need for support gravel. The 0.25 mm punched openings allow the filter sand to sit directly on the underdrain and air scour laterals. The low profile design, 6"- 8" vertical height, and no support gravel allows deeper media stacks than previously considered with other underdrain designs. Uniform introduction of air and water through separate conduits provides superior simultaneous air/water backwash. The underdrains are suited for new designs or retrofits in existing filters.

Pipe bursting
Utilities can burst and replace ductile iron, steel and lined pipe with the new Grundoburst static pipe bursting system from TT Technologies. Pulled by a hydraulic bursting unit, the cutter head's special cutting wheels split the host pipe. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe. Patented Quicklock bursting rods are linked together, not threaded. This saves time, prevents twisting and extends the life of the cutter head over threaded bursting rods.

Leak detection
The Water Hound, from Schonstedt Instrument Co., is designed to pinpoint underground fluid leaks in all types of pipe. Rugged, compact and lightweight, the detector requires a minimum of training. The detector's technology platform combines RISC processor technology with DSP techniques. The units operate with automatic noise velocity speeds, which means they will use the set for specified pipes, or users manually can calculate and set their own noise velocity speeds. Battery charging in (nominally) one hour minimizes equipment down time.
