Sewage pumps
Patterson's Type F and the Forceline® NCS Series non-clog sewage pumps are offered with a sealing arrangement which requires no flush water. The new technology features EnviroSeal's SpiralTrac® throat bushing and Chesterton's Model 442™ split mechanical seals. The system provides savings in areas of maintenance and seal flush water. In addition to savings on initial installation and long-term costs associated with having to flush the stuffing box, maintenance can now be performed to the seal and stuffing box without taking the pump out of service.

Split roller bearings
Craft Bearing has added a new Stainless Steel Series to its line of split roller bearings. The bearings are cylindrical roller bearings with all the inherent features of cylindrical bearings, plus the added benefit of being precision machined into halves. Bearing inspection or change out is greatly simplified and expedited without disturbing ancillary equipment or shaft alignment. Their self-aligning swivel cartridges and pedestal housings are machined from ductile iron for greater tensile and yield strength. The units are powder coated (baked on) rather than painted for a greater resistance to the elements. Sealing is provided by an aluminum triple labyrinth design, using a double row of "O" ring material in the bore.

Air release valve
Asahi/America offers a new Air Release Valve which acts as a controlled venting solution for piping systems. By automatically releasing air out of a piping system, the valves reduces the potential for water hammer incidents to occur due to air pressure building up. The valves are ideal for pump and filtration stations, along mains and main lines and installed at the highest point in a piping system.

Aeration system
The Japanese firm NCC Co. has begun offering a new aeration system called the Tornador. The system creates a "tornado" effect that produces a lifting, turning style of mixing within a basin. The high efficiency aeration system generates air bubbles 50 to 300 microns in size and provides a high shearing force for scum fragmentation. The system uses conventional blowers and is simple to install and operate.

Hydrazine analysis
The Ametek/Thermox Model 7025 Hydrazine Analyzer is designed to measure hydrazine in water on a continuous basis. It uses a mass-transport, limited amperometric cell that directly contacts the sample stream. The sensor uses a platinum anode and silver cathode separated by a porous ceramic housing containing a gelatinous electrolyte. Hydrazine contacts the sensor which in turn generates a DC current directly proportional to the concentration of hydrazine.

Gas dispersion impeller
Chemineer offers the BT-6 Gas Dispersion Impeller, which efficiently disperses gas in liquids at the highest flow rates as a result of its advanced blade geometry. The impeller uses a concave, vertically asymmetrical blade design that not only forces gas to the walls, it distributes the gas throughout the entire liquid volume, bottom to top, resulting in superior mass transfer and uniformity. In studies of dozens of different impeller styles the BT-6 consistently produced the most uniform gas dispersion, increasing the mass transfer rate by as much as 60% when compared to a flat blade, disc-style turbine.

Fieldbus transmitter
Emerson Process Management, Rosemount Analytical, Liquid Division has introduced the Model 5081 two-wire transmitter, the industry's only second-generation Foundation Fieldbus transmitter. The transmitter is available as a HART®-compatible two-wire transmitter. This means a user can completely set up and configure the instrument from a remote location, saving both time and money. Using HART and Foundation Fieldbus digital communications protocols provides access to Asset Management Solutions (AMS) and other host applications.

UV disinfection
The LPX ultraviolet disinfection series from Suntec Environmental incorporates low pressure, high output lamp technology in a UV system that provides higher disinfection levels with fewer lamps than the traditional low pressure, low intensity disinfection systems. Designed with the wastewater treatment plant operator in mind, the systems feature user friendly controls, modular racks and an automatic cleaning system. The company's high frequency submersible ballasts (capable of variable output) are "Cooled by Configuration." Using the wastewater to cool the ballasts eliminates the need for additional cooling systems, cabinets or buildings. This also reduces the overall size of the system and increases its reliability.
