Toxic metal analysis
Safeguarding industrial water quality and monitoring of wastewaters represent an important part of the workload at many water and contract analysis laboratories. Important instrumental considerations include high analytical performance to meet current MDL's and the ability to handle the complex matrices often met with effluent analysis. The Thermo Electron S Series AA is especially suited to this requirement. The GFS97 furnace/autosampler module's performance, vital in waters analysis, is the result of careful optimization.

Pulley alignment tool
SheaveMaster®, a V-belt pulley alignment tool from Ludeca, mounts magnetically to the face of a pulley. A permanently calibrated laser beam fans out striking three magnetic targets on the opposite pulley and measures angular, offset and twist misalignment of the drive. It can be used equally well on chain driven sprockets. The system can be used by one person. Better alignment reduces belt wear, noise, vibration and downtime.
Backwash filter system
The Roberts Maximus™ Automatic Backwash Filter System is an alternative for potable and tertiary filtration. The innovative traveling crane system uses a unique backwash hood which mates to square filter cells. The arrangement of the filter cells allows for wide and long filter basins, which are ideal for large plants. Conventional deep filter media beds increase filter bed efficiency and holding capacity compared to shallow bed traveling bridge designs. Subsurface wash injectors improve media cleaning during backwash.

The LPX Series of UV disinfection system, offered by Suntec, was designed with the wastewater treatment plant operator in mind. The system incorporates innovative lamp technology, which disinfects more wastewater than traditional low pressure, high output lamp designs. Space requirements are reduced and lower quality effluent can be treated. UV lamp output follows changes in effluent quality and flow rate. Even with high UV output, electricity costs remain economical due to low pressure lamp technology. The Scrapper, the company's automatic cleaning system, reduces maintenance. The company's high frequency submersible ballasts (capable of variable output) are "cooled by configuration," which eliminates the need of additional cooling systems, cabinets or buildings.
Suntec Environmental, Inc.
The ability to obtain rapid, accurate and sensitive measurements of respiration and nitrification inhibition, short-term BOD and biomass "health" represents a crucial factor in effective wastewater plant management. To meet these demands, Scottish-based Strathkelvin Instruments Ltd., has launched the Strathkelvin ASR in the US. The system uses six oxygen electrodes and easy-to-use software to measure toxicity on a 20 ml sample of activated sludge. Total respiration inhibition tests take no more than 10 minutes. By using two separate respiration measurements, both nitrification inhibition and inhibition of the BOD-splitting bacteria can be obtained in under 30 minutes.
Strathkelvin Instruments Ltd.
