UV transmission monitor
WEDECO has received a United States patent for is UV Transmission Monitor. The "Hippo" is specifically designed for continuous on-line monitoring of UV transmission. It provides permanent measurement directly in the channel and provides continuous logging capability via a 4-20 mA output or RS232 interface. It feature compact construction and simple installation (no need for pumps, filters or pipelines). The monitoring system consists of a measuring device which is partially immersed in the effluent, and a separate control box with display. The measurement device consists of a UV lamp and two sensors, operating according to the dual beam measurement principle. A special automatic wiping system has been incorporated in the design so that both the lamp quartz sleeve and sensor are kept clean at all times.

Valve tool
Engineers at Westinghouse Savannah River Company (WSRC) have developed a quick method for unseating and removing a ball valve. The ball valve extractor comprises a shaft with a tip at one end, a stop at the other end, and a sliding handle in between. The tip is inserted into the ball valve stem hole and rotated to "lock" inside the valve. The handle is then slid forcibly up the shaft to strike the stop, which causes a hammer-like blow to the valve. This blow unseats the valve. The tool can be used in any position or angle from vertical to horizontal. Interchangeable tips enable the tool to be used with different stem hole configurations and with valves sized for various inner flow diameter openings. The company is seeking interest in licensing this device for the purpose of manufacturing and selling it as a commercial product.

TOC/TN analyzers
Shimadzu has introduced the new TOC Visionary Series, which includes seven different models for measuring total organic carbon (TOC) and total nitrogen (TN). TOC-V offers a choice of either combustion or heated-UV-persulfate oxidation methods - a Shimadzu exclusive. Each unit can be operated stand-alone or PC controlled. The systems enable automatic multipoint calibration from a single standard and an external sparge option can double sample throughput. The total nitrogen option permits simultaneous TOC and TN measurements and an optional air purifier can eliminate the need for purified gases. A septum piercing autosampler accepts three vial sizes to adapt to different analytical requirements.

Cutter assembly
The new Moyno® Annihilator uses bi-directional cutting teeth on the spacers as well as the cutters to prevent the typical problem of string and fibrous material binding or seizing the machine. The patented toothed cutting spacers increase the unit's efficiency, further decrease particle size and reduce the risk of failure from ragging. The Annihilator is designed for use in sewage lift stations, head works and sludge processing systems. The units can process from 300 to 4250 gpm of influent, helping prolong the life of downstream equipment.

Liquid chemical dosing
Hydro Instruments' Liquid Feed System is designed to feed sodium hypochlorite or other liquid chemical solutions. The equipment offers simplicity through its all vacuum operation, purely mechanical design, and visual feed rate indication. Water flow supplied to the system's Venturi nozzle creates a vacuum that draws the liquid chemical solution into the water supply under vacuum. Solution feed rate is visually indicated on a glass flow tube. All-vacuum operation means that breakage of equipment will never cause a chemical leak. Unlike metering pumps, this system will not lose its prime due to off-gassing of the chemical solution.

Swing check valve
The "SWC" series Swing Check Valve from Crispin Valve offers an AWWA C-508-01 solution for check valve applications, including sewage and slurry. Designed with a heavy-duty pivot shaft, the valve accepts both air cushion and oil control devices, and is ideal for installations where back pressure can rapidly reach higher values. Standard with rubber disc seats and stainless steel body seats, the valves can be mounted horizontally or vertically, and are designed so that parts can be maintained without removal from the line. In addition, the pivot shaft extends through both sides of the valve body. This allows it to be changed to either side of the unit, making installation more manageable.

Dispute resolution
Water rights/allocation disputes occur frequently throughout the United States. These disputes often pit jurisdiction against jurisdiction in expensive, time-consuming litigation full of uncertainty and lengthy delays. The Environmental Law Institute® has just published a new book titled "Beyond Litigation: Case Studies in Water Rights Disputes" edited by Craig Anthony (Tony) Arnold and Leigh A. Jewell. Instead of limiting their analysis solely to legal doctrine or theories, the authors probed the history of the disputes - both before and after the judicial decision - to find lessons about how water rights conflicts can be resolved.

Stormwater treatment
Hydroxyl Storm Water Treatment Systems provide treatment of storm water flows prior to discharge from the collection system. The compact, modular units can be installed in new or existing systems. The units disinfect storm water, controlling fecal coliform to levels that are safe for discharge. They remove oils and greases found in the "first flush" of storm water, and reduce suspended solids levels in storm water. The system consists of a solids flotation system combined with an advanced oxidation process that uses ozone and hydroxyl radicals to disinfect the storm water and reduce the levels of chemical contaminants in the storm water. The system is fully automated and capable of responding instantly to storm water events. It can be monitored with SCADA to allow integration into existing municipal infrastructure management systems.

pH, ORP sensors
GLI International has introduced a new line of differential sensors for measuring pH and ORP in a wide range of applications. The pHD-series is the "intelligent choice for pH measurement." They use unique GLI Differential Electrode Technology, wherein three measuring electrodes are used instead of the two contained in conventional pH sensors. The process and reference electrodes measure the pH differentially with respect to a third ground electrode. The sensors have a built-in preamplifier to boost the electrodes' high impedance mV signals for transmission up to 3000 feet. Sensor body materials are available in PEEK® and Ryton®, offering chemical resistance in aggressive process solutions. Convertible, insertion, and sanitary mounting styles enable installation in most process applications.
