Hydraulic modeling
Wallingford Software has released InfoWorks v4.5, an updated version of its hydraulic modeling software. Composed of three modules (InfoWorks WS for water supply, InfoWorks CS for wastewater, sewers and storm water, and InfoWorks RS for river systems), the upgraded software is the world's only integrated modeling package that spans the separate disciplines of water supply, distribution, collection and river systems. V4.5 contains many new input, viewing and editing facilities, including improved graphing and printing and extended management of underlying map layers.

Sludge reduction
Premier Wastewater International's Enhanced Solids Reduction (ESR) process reduces the need for wasting of organic sludge. The ESR process features a novel aeration/conditioning device that aggressively modifies the waste in such a way that it develops a coefficient of decay significantly higher than conventional systems. This increased efficiency permits a small-footprint plant that costs less to install and operate, uses no chemicals, eliminates odors and is very quiet.

Pump hoists
Thern davit cranes and hoists, equipped with a quick-disconnect feature, can be used to simplify the task of placing and pulling pumps. The quick-disconnect allows operators to remove the cable from the hoist while leaving it attached to the submerged pump. The hoists are portable and can be moved from station to station and fitted into fixed bases. They are constructed with corrosion resistant finishes, galvanized or stainless steel throughout.

Sensor/datalogger
The new CR200 series wireless sensor/datalogger from Campbell Scientific provides a low-cost, wireless sensor interface by combining measurement I/O with a 900 MHz spread spectrum radio or with a CDPD digital cell phone. In CSO or SSO monitoring applications, sensor/CR200 combinations are deployed inside the manhole in a NEMA 6P enclosure. The system makes measurements and transmits data to a fixed base station (either a datalogger or computer) or to a mobile station, such as a laptop in a vehicle.

Rotary vacuum filter
The Auto-Vac filter from Alar Engineering will remove virtually all suspended solids from liquid slurries. It is self-cleaning with every revolution; it never blinds. With the aid of a diatomaceous earth filter media, solid particles as small as 0.5 micron are removed from the liquid being filtered. The solids are continuously removed from the surface of the filter media by a Stellite Knife blade and then deposited into a receptacle for disposal. The filters can be used to dewater sludges, greatly reducing hauling costs.

pH/conductivity meters
Cole-Parmer Instrument Co. presents the Oakton pH/Con 10 Meters for the measurement of pH, conductivity, and temperature. The meters are available in standard or IP67-rated waterproof models. They now include an improved three-in-one pH/conductivity/temperature probe with a 10-ft. submersible cable, making this meter ideal for environmental, industrial, laboratory, and water quality applications. The pH electrode features a double-junction reference, with an increased fill volume and a protective/storage cap. An improved temperature response and redesigned conductivity cell ensure more consistent readings, easier maintenance, and no air bubble entrapment. A down-well design probe is also available with a 10, 25, or 100 feet of cable.
