Municipal Filtration Co. has introduced the Muni-DiskTM cloth media filter. The filter is designed to follow municipal activated sludge and SBR facilities, providing tertiary wastewater treatment in a compact, efficient package. The systems use a combination of differential head and a series of simple open-close valves to provide wastewater filtration and backwash flow control. Vertically placed cloth media panels reduce equipment footprint. Pumps, drive motors, chain gears, high-pressure spray bars, backwash and sludge manifolds, and mechanical wear items are all eliminated.

Sierra Instruments steps into the Ultrasonic Flowmeter market with the release of its new Innova-SonicTM Ultrasonic Flowmeter product line. The meters are universal transit-time instruments incorporating the latest advances in digital signal processing. The portable version features a Bluetooth® wireless PDA interface. The flow meter is also available with fixed display readout in a choice of either clamp-on or insertion transducers. While principally designed for clean liquid applications, the device is tolerant of liquids with small amounts of air bubbles or suspended solids. The instrument can be configured via keypad without any additional programming devices and is packaged in a die cast NEMA 4X (IP65) housing.

seepex progressive cavity pump universal joints are now available with ratings to 360 psig. This allows the pumps to be used on applications with high suction heads, low NPSHA applications with reverse rotation (common in vacuum condensation or suction lift applications) or in vertical pumps where the joints are exposed to the rated discharge pressure of the pumps. A new proprietary technology allows the joints to be hydraulically balanced and reinforced against implosion from high pressures. The joints are long lasting because they are positively sealed with an elastomer cover and two holding bands and lubricated with high temperature grease especially formulated for this service.

The Hach Homeland Security Technologies division has been issued a patent for the proprietary analytic technology in its Event MonitorTM Trigger System - the diagnostic software for Hach’s water distribution monitoring system. The patented technology - which analyzes deviation vectors in water parameters - is the first of its kind to be applied to water quality monitoring. The EPA-funded ETV testing program has verified the technology is able to detect, alert and classify a wide variety of contaminants as well as detect, alert, classify and learn real-world events in water distribution systems.

Krohne’s new Waterflux electromagnetic water meter has a high sampling rate and long battery life. This GSM-capable water meter can remotely transmit flow rate readings using the Internet or cellular telephone. It is designed for use in traditionally problematic applications, such as water with suspended particles, bi-directional metering, or flow metering for pipe sizes larger than DN50. Its unencumbered measuring path offers reduced pressure drop and long-term stability. The meter features a built-in module that includes a data logger and a GSM transmitter designed especially for use in remote pipes or shafts. The data logger stores all flow data, including peak values and low flow rates during nighttime operation.

Amiad Filtration Systems has released its next generation thread technology filter, the AMF2-93K. It is an automatic, self-cleaning, string-wound, Micro-fiber filter. This model is added to the established larger unit, the AMF2-370K (formerly known as the MTG). With its new cassette design and thread windings the new filter offers removal efficiency of suspended matter down to 3 microns. It is capable of handling up to 220 gpm and its operating pressure is up to 150 psi. The permanent cassettes, located inside the filter, are tightly wound with multiple layers of high strength polyester thread serving as both a surface strainer and in-depth filter. The filter is designed for smaller flow rate applications in desalination, drinking water treatment plants, tertiary wastewater treatment, and pre-filtration.
