Electromagnetic WaterMaster flowmeters for water and wastewater are available in sizes ranging from 1.5 to 84 in. All sizes may be buried. The flowmeter features a backlit graphical display, and “through-the-glass” control enables operators to input data quickly for all user-specific parameters in the field. ABB Instrumentation (Cary, N.C.).
The SB400 potable-water-tank mixer is designed to completely mix potable water tanks up to 300,000 gal. The mixer is designed for use in smaller towns requiring only one tank or for multiple tanks in larger municipalities and is certified against potable water contamination by NSF/ANSI Standard 61. The unit is collapsible and fits through an 18-in. hatch. Equipped with chemical injection capability, it is available with the portable SolarBee Chlorine Boost System. SolarBee (Dickinson, N.D.).
Polymer Activation System
The ParaDyne™ liquid-polymer activation system for water and wastewater treatment applications strips oil from oil-phase continuous polymer emulsions while hydrating the polymer molecules for lower polymer consumption. The system is available in several sizes and capacities to meet specific customer needs. Enpro Technologies (Lee’s Summit, Mo.).
Carbon Dioxide Pump
The self-contained SFT-10 liquid carbon dioxide pump pressurizes carbon dioxide up to 69 MPa (10,000 lb/in.2) at flow rates from 0.01 to 24.0 mL/min. The SFT-10 utilizes dual sapphire syringe pump technology and may be acquired as a stand-alone carbon dioxide pump or used as part of the SFT-100/SFT-100XW supercritical fluid extractors. Supercritical Fluid Technologies Inc. (Newark, Del.).
The 1800A Series full-lift-type valve at 10% overpressure is designed for applications requiring low emissions and operation near tank maximum allowable working pressure. The valve is available in flange sizes ranging from 2 in. (DN 50) through 12 in. (DN 300). Groth Corp. (Stafford, Texas).
The 2-, 3- and 5-way manifold valves combine the function of a tee, calibration valve, isolation valve, and all tubing and fittings into a single valve configuration and are designed to connect a system impulse line and transmitter. Metal-seated units feature a maximum pressure rating up to 6000 lb/in.2 at 200°F (414 bar at 93°C). The pressure rating at maximum temperature for PTFE units is 4130 lb/in.2 at 450°F (284 bar at 232°C) and 1500 lb/in.2 at 1000°F (103 bar at 538°C) for Grafoil units. Each has a 0.156-in. (4.0-mm) orifice. Innovative Pressure Technologies (Erie, Pa.).
Video Crawler System
The P350 flexitrax™ portable crawler system provides digital video in any environment. The system supports three interchangeable high-resolution cameras. Each camera features ultrabright white LEDs that ensure a clear picture. An 8-in. thin-film transistor screen displays digital video. The command module stores survey data direct to solid-state Compact Flash cards and can send photos wirelessly using Bluetooth®. Pearpoint (Thousand Palms, Calif.).
The VANOX POU system removes total organic carbon in point-of-use ultrapure-water-treatment systems for semiconductor applications. This oxidation process reduces TOC to 0.5 ppb and can treat seasonal TOC variations in feedwater. The system reduces particles to less than 100 units per liter at 0.05 microns. Siemens (New York).
