Sodium hypochlorite cell

The new CT Cell from Severn Trent Services' ClorTec line produces 0.8% sodium hypochlorite solution. Systems range in size from 2 to 3,000 pounds per day equivalent chlorine demand. Typical applications are municipal and industrial water and wastewater treatment plants. The new patent pending design delivers a significant reduction in both salt, power and disinfection byproducts resulting in an overall net reduction of 20% in operating cost.

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.

Pressure data loggers

Dickson has introduced its Stainless Steel Pressure Data Loggers, models PR100 and PR300, to its current line of instrumentation. The loggers feature a waterproof stainless steel case, which can monitor pressure ranges from 0 to 300 psi and can operate in temperature ranges from -40 to 185degreesF. The PR100 and PR300 feature a 5-year battery life and can record almost 8,000 samples. These loggers are ideal for investigating pressure complaints, checking for system leaks and recording pressure in compliance to regulations or quality programs. A user can download all data to a PC for viewing, graphing, or printing with DicksonWare™ software.

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.

Underwater repair putty

Devcon Underwater Repair Putty is a nonrusting, epoxy-based compound that penetrates moisture and forms a strong, permanent seal even under water. It is ideal for repairing, patching, or rebuilding wet or submerged equipment. The putty bonds securely to steel, iron, aluminum, brass, bronze, concrete, wood, and selected plastics. Easy to mix and apply, it cures at temperatures as low as 40° F. Maximum service temperature is 250° F. Because the putty eliminates the need to dry substrates thoroughly before beginning repairs, it is ideal for a multitude of emergency and routine maintenance tasks.

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.

Laboratory workstation

Zymark Corporation has launched its Mini-Staccato Workstations, a new breed of small flexible integrated systems providing laboratories the benefits of a scalable automation platform capable of evolving to meet future needs. The systems begin with a Twister™ II and a single workstation such as a reader or microtiter plate sealer. In this assisted workstation configuration, the Twister II acts as an unattended plate server with a large storage capacity providing significant walk-away time for the operator. As application needs expand, another device, such as the Zymark Sciclone™ ALH liquid handler can be integrated by using CLARA™ 2001 integration software.
