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.
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.

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.

The Remediator® Grease Treatment System offered by Jay R. Smith is designed to eradicate suspended fats, oils and grease at the source. This task is accomplished through the use of environmentally safe live bacteria which have been specially selected and bred to have broad appetites for the rapid reduction of fats, grease, sugars and other complex carbohydrate and proteins.

Custom Sensors & Technology introduces a new UV, VIS, or NIR based photometric transmitter that can measure the absorbance, reflectance, or fluorescence from a liquid or gas process stream to control the feed rate of a chemical additive, thereby preventing an overfeed or underfeed condition. The photometric transmitter requires only 24 vDC and can be supplied to meet C1D1 or C1D2 electrical area classification.

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.
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.

Fibox has introduced an enclosure ventilation device featuring a molded in place gasket that ensures a tight seal and eliminates the loose, separate gasket required in older models. Without a design change, users can now select an easier to install, cost saving assembly with the same mounting hole pattern and footprint as in previous models.

Water meter testing
Ford Meter Box announces the availability of the Automated Measuring System, AMS. The new system takes the Ford test bench to the next level of water meter testing. It is available for new or any existing Indianapolis Style or Standard Ford test benches. The system consists of modular components and combines the trusted method of weighing metered water with computer automation to ensure accurate measurements.

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.

Distributed control system
Invensys has introduced an expandable Distributed Control System (DCS) featuring architecture by ArchestrA. The Foxboro® A2™ automation system integrates technology, expertise, and services from across Invensys to provide end-users in general process plants with an automation solution that fits their applications better than programmable Logic Controllers (PLCs) and costs less than traditional DCSs. Based on the company's Eurotherm™ technology, the system I/O combines flexibility, high capability and ruggedness at a low price point. A wide variety of different analog and digital process inputs and outputs come in high-density configurations that minimize space requirements. The system I/O can be remote-mounted on DIN rails close to the process and communicate with the system controllers via Profibus, Modbus, or DeviceNet digital communications.

The Hose Monster® from Hydro Flow Products is designed to accurately measure flow rates and safely diffuse and divert potentially dangerous water flow. Traffic interference and property damage are minimized. The product is used with a short length of hose to send water into a gutter or sewer. The patented design cancels the thrust so the hose just lies where you put it. The exact orifice with laboratory proven coefficient and precisely positioned pitot ensure consistent flow rate measurements.
