Thrush Co. Inc.

Air and Dirt Separator

Thrush’s Aar-O-Vent air and dirt separator is designed for corrosion protection in hydronic piping systems. The device uses a stainless-steel coalescing filter medium to separate air and dirt from water in systems that can cause damage to pumps, seals and valves. Features include a gauge tap on the inlet and outlet connections, a removable bottom cover for cleaning the coalescing medium, and a blow down valve for flushing collected sediment. Available sizes for the separator range from 1.5- to 24-inches.

    Red Valve Co.

    Slurry Knife Gate Valve

    Red Valve’s Series DX slurry knife gate valve is designed for heavy slurry applications. When the valve opens, reinforced elastomer sleeves seal against each other and provide a complete full-port opening, which minimizes turbulence and wear. When the valve is closed, the sleeves provide a drop tight seal. Each time the valve strokes, it is designed to discharge a small amount of slurry, keeping the gate path and seat area clear of entrapped particulates.

      Control Microsystems

      Pump Station Controller

      The FlowStation 110 from Control Microsystems is an out-of-the-box pump station controller package designed for use in storm and wastewater lift stations and common pump-up applications. The components consist of a pump controller, a color touch screen local operator interface, GPRS modem, SMS and e-mail alarming. An integrated BlackBerry interface is designed for central viewing and alarm acknowledgement. For larger water control systems, the package provides interface tools that exploit the product’s integrated Web server and Ethernet capabilities.

        Siemens

        Electrodeionization Module

        The Ionpure VNX-HH electrodeionization module from Siemens provides feed water hardness tolerance. The device features a hardness level of 2 ppm as CaCO3. The module has options for treating difficult feed water, and offers capital cost savings by eliminating the need for two-pass reverse osmosis.


          General Monitors

          Toxic Gas Detector

          The TS4000H Intelligent Toxic Gas Detector from General Monitors is compatible with HART communication protocol. The detector offers protection against a wide range of hazardous industrial gases, including chlorine and hydrogen chloride, and is able to safeguard against oxygen deficiency. Designed for use in waste and wastewater treatment sites, the device features event logs, an LED display and explosion-proof housing. The system displays gas concentrations up to 500 ppm, fault codes for troubleshooting, and prompting when calibration is needed.

            Red Valve Co.

            Control Pinch Valve

            Red Valve’s Series 5200 control pinch valve is designed to provide accurate, repeatable control of abrasive and corrosive slurries. The elastomer sleeve produces a smooth venturi flow path that outlasts gate, plug, ball and stellite-coated control valves. The reinforced elastomer sleeve is the only wetted part of the valve, which eliminates the need for packing, valve seats and mechanical parts. The cone sleeve trim throttles applications for tighter control and range.

                Dow Water and Process Solutions

                Arsenic Removal

                Dow Water & Process Solutions ADSORBSIATM As500 is a non-regenerable single-use product for the removal of arsenic. It is stronger, reduces turbidity, and has fewer backwash requirements than the previously released media. The product meets the California Total Threshold Limits as well as TCLP and Calif. WET tests. The nano-crystalline structure provides faster kinetics, allowing smaller diameter vessels and system footprint. It removes arsenic across a wide pH range, without the use of pretreatment.



                  Watson-Marlow Bredel

                  Peristaltic Pumps

                  Watson-Marlow’s 520, 620 and 720 Series of cased peristaltic pumps are NEMA-4X-rated with certified PROFIBUS DP networking capabilities. With two-way real-time communications, the tubing pump skid systems require minimal ancillary equipment and no back pressure regulators, de-gassing valves, strainers or pulsation dampeners. The skid systems deliver an accuracy of +/- .5 percent.

                    Geoprobe Systems

                    Direct Push Machine

                    The Model 7822DT subsurface machine from Geoprobe Systems has direct push functions and geotechnical capabilities. Features include a GH64 hammer with modular percussion power cell technology and integrated two-speed bidirectional rotation. The rear stabilizer contains a drop rack system, which allows operators to move accessories and tools weighing up to 2,000 lbs. Three auxiliary hydraulic power ports can be controlled by an operator via the control panel.
