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.

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.

Condensate filters

Disposing of compressed air condensate is a major environmental concern. This oil/water mixture is classified as hazardous waste and cannot be discharged into municipal wastewater systems unless the oil and contaminants are removed. The Kaeser Condensate Filter (KCF) is designed to filter out oil and other contaminants making the water safe for disposal. The key to the KCF function is the three-stage, self-contained plastic filter cartridge, which is convenient for replacement and disposal. The unit requires no electricity and little maintenance. The filter cartridges are designed to handle most compressor lubricants and are available in two sizes. The KCF-20 is designed for flows of approximately 100 cfm, while the KCF-100 will handle flows up to 500 cfm. For larger flows, simply connect multiple KCF units together with an optional Flow Splitter.

Plug valves

Val-Matic Cam-Centric Plug valves are ensured of a tight shaft seal through the use of Vee type packing and Packing Overload Protection (POP) shims. The packing is adjustable and replaceable and is protected by Grit Guard grit seals, which keep line media away from the packing. Pop shims are mounted under the packing follower and take the guesswork out of adjustment. The operator simply loosens the packing follower and removes one shim at a time, tightening the packing and assuring a good seal.
