Lantec HD Q-PAC® media for use in biotrickling filters is made from polypropylene that is highly resistant to both dilute and concentrated mineral acids. It is stable and unchanging over long periods of time and should not require replacement in most applications. The media provides an extremely low pressure drop. Because of its self cleaning feature, the media does not have to be cleaned under normal operating conditions. When loaded with biofilm, the media can develop effective specific surface areas of up to 300 ft2/ft3. Lantec Products Agoura Hills, CA Tel: 818-707-2285
Portable trash pumps

Godwin's Dri-Prime CD300M model 12" portable trash pump handles flows to 6,000 gpm, heads to 200 feet, and solids to 3.75" in diameter. It is designed for use in large volume dewatering jobs with high heads. Like all the company's Dri-Prime pumps, the CD300M primes and re-primes automatically from dry to 28 feet of suction lift. Two unique features of the pump include direct coupling to the engine flywheel, which enhances compactness and increases reliability, and a double, high pressure oil bath mechanical seal designed with solid silicon carbide faces that allows the pump to run dry during intermittent flow without damage.

Doppler flow meter

American Sigma, a Hach Co. brand, has released the new 8300 Permanent Closed-pipe Doppler Flow Meter. The meter provides an economical alternative to the more expensive flow monitoring options while also providing an accurate flow reading, especially at lower flow rates. It uses Rapid Response Slope Detection Technology with advanced algorithms and statistical analysis to detect sudden changes in flow rate. When flow significantly changes, the instrument drops the previous values from the averaging, uses current data to calculate flow, and outputs a response representative of the true flow rate in the pipe at any given time. The non-intrusive meters also feature grease free transducer pads. The pads are simply clamped to the outside of the pipe without the need for messy contact pad grease. Hach Co.

Saftronics, a provider of variable-speed drives and starters for electric motors, is now offering the HR1018 Harmonic Reduction Technology package, an 18-pulse AC drive that reduces the total harmonic distortion common to standard 6-pulse drives. By reducing harmonic distortion, the unit minimizes harmonics interference that can impair sensitive electronic equipment such as sensors, meters, computers and communications devices common to water/wastewater treatment facilities as well as minimizing heating in motors, transformers and wiring. At the same time, it improves power factor to help companies avoid utility penalties based on power factor, current distortion and peak demand charges. The HR1018 is designed to meet IEEE 519-1992 requirements at the drive terminals - without the cost and complexities of external filters or other equipment typically required to reduce harmonics.
