Although most utilities will move quickly to full mesh network functionality, the system can operate indefinitely using any mixture of collection methods. Each endpoint functions as both a meter interface unit and a repeater. Data is “hopped” between endpoints as they create multiple, redundant pathways to the gateway. The mesh is “self-healing,” in that it is designed to reroute around issues without user intervention. Mosaic systems also require far fewer (and far less expensive) gateways than traditional network designs. Endpoints store hourly consumption for 365 days; available on demand. Users can define conditions that trigger the endpoints to transmit detailed usage data.

DAF system

ITT Leopold’s Clari-DAF system eliminates taste-and odor-causing algae and other low-density particles that are difficult to remove by gravity sedimentation. The system uses a process in which air is dissolved into water under high pressure. Upon release of the pressurized air into the bottom of the system’s chamber, millions of microbubbles are created like the ones in milky white water. The countless microbubbles attach themselves to pinpoint floc particles and float them to the surface for removal with a mechanical skimmer or by hydraulic overflow. A Clari-DAF system is applicable to virtually any stored body of water, especially colored water, algae-laden water, turbid water, water with high seasonal iron and manganese content and low temperature water. The system typically removes 97 percent of algae and 96 to 99 percent of turbidity.

The Megalug® Series 1100 products from EBAA Iron are used on ductile iron pipe and steel pipe. Series 2000PV can restrain AWWA C900, C905 and IPS OD PVC pipes. Each product uses gripping wedges to add resiliency to pipeline designs. The company’s Flex-Tend® flexible expansion joints are used to connect pipelines to tanks or other structures that may be vulnerable to damage from ground motion. They are capable of deflecting up to 20 degrees per ball in any direction while expanding or contracting. Its Megaflange® restrained flange adapter, series 210, is generous in its deflection limits and may be cut to length at the job site. It provides joint deflection up to 5o depending on pipe size and can be used on ductile iron, PVC and steel pipe. The wedges securely grip the pipe, and the easy disassembly allows for quick removal of values, meters or fittings.

Koch Membrane Systems will display the MegaMagnum® element. The world’s largest commercially available RO and NF element, it significantly reduces the cost, footprint and installation time of municipal and industrial water treatment systems. A single 18" x 61" spiral element contains 2,800 square feet of membrane surface area, compared to 400 square feet in commonly deployed 8" x 40" products. The elements are available from KMS separately or as part of a standard, packaged system. MegaMagnum systems require half the floor space of racks with 8-inch membrane elements. The company will also display the PuronTM MBR modules which are ideal for treating municipal effluent.

The Rosemount Analytical Model FCLi, which requires neither reagents nor an auxiliary pH sensor, is now available with the company’s newest analyzer, the Model 1056. The analyzer has a high-contrast display, a built-in troubleshooting guide for warnings and faults, and an improved calibration menu. The principle of operation of the FCLi remains unchanged. An acidic fill solution adjusts the pH of the sample inside the sensor, producing a reading that changes less than 5% per unit change in pH. The instrument can be used in natural and treated water having pH as high as 10.0.

The Longwatch Video Surveillance System provides operators with the visual information they need to monitor and manage remote facilities, like well fields, pumping stations, and water towers. Operators receive automatic video alarm notification that can be used to verify if an intrusion warrants immediate action, no response, or is a false alarm. Unlike traditional stand-alone security systems that use closed-circuit or broadband networks for video transmission, the Longwatch system can use existing SCADA low-bandwidth communications networks to transmit video. It allows operators to manage both system and security alarms on the same system.

Keller America has introduced the LevelRatTM, a lift station level transmitter with a non-fouling, flush KynarTM diaphragm. Specifically designed for applications that would clog or foul a conventional level transmitter, the device operates in nasty environments common in sewage lift stations and other greasy/slurry installations. The transmitter is also available with an optional lightning protection package. Transmitters so equipped carry a lifetime guarantee against damage from voltage surges, including those induced by nearby lightning strikes.

The Trident® HS system will be part of the Siemens Water Technologies exhibit at the 2007 AWWA ACE. The multi-barrier packaged treatment unit addresses the Long Term Enhanced Surface Water Treatment Rules and other regulations. A high-rate two-stage clarification system removes both settling and non-settling solids while providing built in redundancy. After clarification, treatment is completed with an integral media filter and UV disinfection unit. A to-scale model showing the four major treatment stages will be on display. Since its introduction in 2005, the system has continually proven its effectiveness at reducing turbidity, color and TOC in surface water supplies. The unit provides pretreatment for NF/RO high pressure membrane systems. The two-stage clarifier may also be used to provide micro- or ultra-filtration membrane pretreatment. In addition to drinking water treatment, the Trident HS design is ideal for ultra low-level phosphorus reduction and water re-use for wastewater applications.

Tideflex Technologies’ Tideflex® Mixing System (TMS) greatly improves the quality of drinking water in finished water storage reservoirs. The system is a combination of Tideflex® Check Valve technology and a proprietary piping manifold system. It can be installed in new or existing water storage tanks of all shapes and sizes to eliminate stagnation and short-circuiting. Operating on the differential pressure that is already in place, it keeps energy costs low, while the all-elastomer construction of the check valve reduces maintenance.
