Reservoir mixing
The Vortex™ reservoir recirculation system from Superior Water Technologies is installed at the top of a tank, eliminating the need for boats or divers. Maintenance is minimal due to the design and quality of components used: the system is made almost entirely of 316 stainless steel. The entire tank is mixed evenly and quickly using pressurized jets of water ejected from a patent pending multi port nozzle system that pulls colder water from the bottom of the tank and discharges that water upward and spiraling, creating a vortex spreading outward from the center of the reservoir. All serviceable components are located outside the tank. The system can mix any size reservoir and achieves optimum performance when reservoir levels are at their highest.

Disinfection controllerWalchem has added a new free chlorine/bromine sensor with extended pH range to its WDIS 410 Controllers. These new sensors have highly reduced dependence on pH and are suitable for applications where the water has a pH range of 4-12. The controllers also have a new Generic Sensor input option that allows the controller to use any disinfection sensor with a mV input. The user programs the slope and offset of the sensor, so virtually any measurement range can be accommodated. The new generic input will allow Walchem to continue to add new sensor options to meet customer needs.

Biosolids dryingSiemens Water Technologies sludge belt dryers offer municipal wastewater treatment plants an opportunity to reduce costs and benefit from their biosolids handling process. The low temperature drying system is ideally suited for heat recovery using low energy or "waste" heat sources. In the thermal drying process, the final product is stabilized in a dry granular form that reduces the costs associated with storage, delivery, use or disposal. The dry product can be beneficially used as a biofuel or renewable energy source. The dryer's low-profile, compact design offers capacities up to 13,000 pounds of water evaporated per hour.

Vibration monitoring
Ludeca has introduced Vibxpert II, the latest addition to the Prueftechnik family of portable route-based vibration data collectors. The new instrument is rugged and lightweight and combines the advantages of a rapid processor with a color VGA display. Enhanced with an Fmax of 51KHz and up to 102,400 lines of resolution, the basic platform is a 1-channel device which can be upgraded at any time to two individually configured channels. All forms of machine vibrations, bearing conditions, process data and visual inspection information can be collected and stored on the expandable compact flash card (up to 8 gigabyte) for report generation or for later transfer to the Omnitrend® software for further analysis, reporting and archiving.

Cyanide analysisOn August 6th, 2010, the U.S. EPA Administrator signed a Methods Update Rule (MUR) proposing new test procedures for analysis of pollutants under the Clean Water Act, including total cyanide. Labs will now be able to analyze NPDES wastewater samples for total cyanide without a preliminary two hour acid distillation step by following ASTM Method D 7511-09. The CNSolution™ Cyanide Analyzer uses in-line UV digestion to dissociate metal-cyanide complexes and measure total cyanide in minutes by ASTM D 7511-09.

Presence/absence testHach has expanded its presence/absence product offering to include Modified Colitag, the fastest presence/absence test in the market-with a 16 or 22 hour testing timeframe. This allows drinking water facilities to begin a test at 5 p.m. and get EPA-approved results by 9 a.m. the following morning. The product also provides flexibility by offering two testing parameters in one product: a 16 hour or a 22 hour test. Being able to select between two test periods allows drinking water facilities to set up the best timeframes for their staffing and to adjust tests as needed, without changing methods.
