Hach Introduces Pocket pH Meters

H-Series miniLab pocket pH meters from Hach Co. feature a non-glass silicon chip sensor that provides readings in seconds. It requires no filling solutions and stores dry for easy maintenance. Three different models are available, providing 1-, 2- or 3-point calibration, temperature display and pH resolution up to 0.01. 800/227-4224;

Fluidyne Offers ISAM Sludge Reduction

The ISAM sludge reduction system from Fluidyne Corp. incorporates a constant-level anaerobic basin followed by a surge/anoxic/mix (SAM) tank, and an aeration basin that incorporates BOD, TSS and nitrogen removal along with sludge reduction in an integrated system. Complex organic solids undergo hydrolysis to simpler soluble organics, which pass to the SAM tank. In addition to flow regulation, the SAM tank provides an anoxic environment for rapid denitrification of recycled nitrates and concurrent stabilization of the soluble organics from the I-Tank. The conditioned mixed liquor then passes to the final aerobic tank for completion of BOD and nitrogen removal and solids separation. 312/266-9967;


The high-oxygen transfer of the TWISTER low-speed aerator from AEROMIX Inc. makes it useful for high-oxygen-demand biological treatment applications. Designed for long-term continuous operation, the unit uses a composite material in its hydrodynamically efficient rotor. The rotor is molded to optimize the spray of water droplets, resulting in high-oxygen transfer rates. Models are available from 2 to 150 hp. 763/746-9294;

Longwatch Releases V5.1 Video Surveillance System

The Version 5.1 video surveillance system from Longwatch Inc. is available in three platforms, eliminating the need for custom programming and creating a “fast track” for integration with a process control, HMI/SCADA or automation control system. The console recorder platform monitors what operators are watching on HMI displays and records their keystroke action, revealing what operators saw on the screen during an “event” and what they did about it. The video historian platform automatically links and synchronizes historical trend information and stored video from multiple cameras in the field or process, enabling the operator to see what happened when various trend conditions occurred. The surveillance platform eliminates blind spots in video surveillance. Event messages automatically contain video snippets that show what happened before, during and after an event to help reduce false alarms. 781/255-7400;

SEL Offers Satellite-Synchronized Clock Display

The SEL-9929 satellite-synchronized clock display kit from Schweitzer Engineering Laboratories Inc. includes the SEL-2401 satellite-synchronized clock, SEL-3401 digital clock display, GPS antenna and all cables.

Multiple clock displays can be connected to cover a wide area. 509/332-1890;

Krohne Introduces Optiswirl 4070 Flowmeter

The Optiswirl 4070 C flowmeter from Krohne Inc. combines a vortex flow sensor with built-in temperature compensation and optional integrated pressure in a two-wire configuration. The meter is designed to deliver accurate measurement of standard volumetric and mass flow of conductive and non-conductive liquids, gases and vapors. It features a non-wearing, fully welded stainless steel structure that is resistant to corrosion, high pressures and temperatures. It also features an Intelligent Signal Processing System that allows for stable flow readings while eliminating noise and spurious frequencies. 800/356-9464; www.krohne. com/northamerica.

Forsta Introduces Low Pressure Filters

The Low Pressure Series of self-cleaning water filters from Forsta Filters range from 2 to 30 inches with flow rates to 20,000 gpm in a single housing. The filters can be backwashed with line pressure as low as 15 psi. Featuring Green-Clean technology, the point-of-suction backwash takes less than 16 seconds and uses less than 1 percent of the total flow per backwash without interrupting the main flow. Filters are available in stainless steel, carbon steel with epoxy coating or duplex stainless. 888/936-7782;

Best Controls Introduces PC 4000 Controller

The PC 4000 controller from Best Controls is a dedicated controller for pressure control applications using variable-frequency drives. Features include 1 to 4 pump configuration, P.I.D. control, 0-200 psi pressure transmitter, graphic screen display with backlighting, automatic alteration, password protection and serial communication. 800/349-1905;

AceOps Offers PowerPoint-Based Testing Programs

Endless Math and Easy Test PowerPoint-based testing programs for wastewater operators from the Alliance of Certified Operators, Laboratory Analysts and Specialists (AceOps) feature multiple-choice and some true-and-false questions. Questions are randomly displayed. Individuals can choose the number of questions they would like to try and can exit the program at any time. Score is kept but not recorded. Some questions have references based on WEF manuals and the California State manuals. Some questions have video, graphics and PDF files attached. A computer with CD player and PowerPoint 2003 or 2007 is required to run the program. 515/255-4580;

ECD Offers CDA-22 Chlorine Dioxide Analyzer

The CDA-22 chlorine dioxide analyzer from Electro-Chemical Devices Inc. features a panel-mounted plumb-and-play design and automatic flow control in a low-maintenance complete measurement system. The unit is designed to measure chlorine dioxide in concentrations ranging from 0.05-20 ppm. It incorporates a CIO2 sensor, automated flow control device and analyzer/controller mounted on a PVC panel and can run up to one year between electrolyte/membrane changes. 800/729-1333;

FCI Offers ST51 Flowmeter

The ST51 flowmeter from Fluid Components Inc. is designed for the measurement of methane (CH4) and other combustible greenhouse gases. The explosion-proof device requires virtually no maintenance and features no moving parts.

R+W America Offers ST2 Torque Limiter

The ST2 series high-capacity torque limiter with integral flex coupling from R+W America makes use of a vibration damping jaw-type coupling in conjunction with a resettable torque limit function. After reaching the preset disengagement value (from 738 to 118,000 ft/lbs) the coupling fully disengages and freely rotates over a high-strength internal bearing until the machine shuts down, helping avoid damage to gearboxes and shafts due to overload. Resetting the coupling requires snapping the individual plungers back into engagement with a pry bar or mallet. The safety couplings have four body sizes and from three to nine plungers, depending on torque setting. The adjustable plungers can be added or removed after installation should the release torque value be miscalculated. 630/521-9911;
