Thompson Pump and Mfg.
Thompson Pump’s 4JSVC-EBS-40 heavy-duty electric driven pump eliminates product blow-by. The unit offers large solids handling capabilities, ideal flows of 1,175 gallons per minute and high heads to 150 feet. The pump is designed for bypass and construction dewatering applications.
Koch Membrane Systems Inc.
Koch Membrane Systems’ MegaMagnum reverse osmosis and nanofiltration system uses spiral-wound membrane elements to reduce the complexity, footprint and installation time of municipal and industrial water treatments. The system’s pre-engineered skids are available in four configurations with nominal flow capacities ranging from 0.5 to 2 million gallons per day. The system mounts on one or two skids, depending on capacity.
SolarBee’s solar powered floating water circulator is designed to minimize aeration equipment run-time in wastewater and industrial water reservoirs. A low-voltage motor and on-board battery system supply power to the unit. The product’s circulation technology creates a near-laminar flow pattern that mixes the water column and improves distribution of dissolved oxygen. The mixing improves regulatory compliance by reducing biochemical oxygen demand, total suspended solids, ammonia, odors and sludge buildup.
Inge watertechnologies AG
Inge watertechnologies’ Multibore membranes are designed to withstand fiber breakage. The permeable units provide high rates of virus and bacteria retention and are resistant under heavy loads. The membranes offer retention levels for MS2 phages greater than log 4, which corresponds to a 99.9 percent retention rate. The units’ high permeability decreases the required amount of transmembrane pressure for treatment plant operations. The membranes are designed for ultrafiltration processes and drinking water purification.
Enpro’s ParaDyne liquid polymer activation system strips oil from oil-phase continuous polymer emulsions and hydrates polymer molecules. The system’s impeller disc is designed with multiple vanes that extend from the inlet and outlet. The vanes are recessed and tapered in two axes, providing rapid blending and shear of the solution through the system’s inversion zone. The system can blend a 0.1- to 1-percent concentration of homogenous polymer solution with water.
Smith and Loveless
The PISTA 360 grit removal system from Smith and Loveless is designed to increase velocity during low-flow periods and maintain grit capture during surges. The device’s v-force baffle is positioned in a 360-degree, flat-floor grit chamber that creates a forced vortex for capturing grit at all flows. The baffle design serves as a water level control device.
Campbell Scientific’s CS525 submersible ISFET pH Probe provides measurements in aqueous or semi-solid solutions and can be placed in tanks, pipelines and open channels. Its silver/silver-chloride potassium chloride reference system allows the probe to be used in liquids containing high solids, aggressive chemicals or biological materials. The device uses Sentron’s ion-sensitive field-effect transistor semiconductor as its pH-sensitive element.
Wilden Pump and Engineering Co.
Wilden’s T-Mag Mag-Drive pumps feature patented fluid paths that surround the pump’s bushing, which prevent heat buildup that can damage or disable the shaft bushing. The pumps offer high-performance magnetic coupling and
a buffer designed to absorb vibration and shock. Computerized fluid dynamics control the product's stream pattern.
MWH Soft’s V8 InfoSWMM design program provides urban drainage network analysis. The GIS-integrated software’s management functions include water quality assessment, pollution prediction, sediment transport, urban flooding, real time control and record keeping. The product is designed to help users manage urban runoff and wet weather water quality problems in combined, sanitary and storm sewers.
Metrohm’s 850 IC system and particle-into-liquid sampler tests air pollution by providing quasi-continuous measurements of inorganic compounds in ambient air. The system removes gas-phase compounds, and the remaining aerosol particles are dissolved to water via a supersaturated steam phase. The liquid sample is then transferred to the IC system for analysis. The unit provides a high temporal resolution of measurements, allowing users to record changes in the ionic composition of ambient air.
Jade Engineered Plastics Inc.
Jade’s JLON PTFE stock bearing shapes imbed into shafts, creating a surface interface. The shapes feature four wear-resistant formulations with no water absorption and are offered in 3.8- to 36-inch O.D. sizes. The products are available in the 2100, 4200, 5500 and 7000 models.
Schroeder’s SC automatic self-cleaning filters contain slotted tube and mesh filter elements that capture contaminating particles. The units are available with flow rates up to 33,000 gpm and ANSI flange sizes ranging from 2 to 36 inches. The single-element cleaning process allows the total filtered flow to remain constant during cleaning.
Advanced Drainage Systems
Advanced Drainage Systems’ Flexstorm inlet filters function as stormwater sediment control units. The units filter silt, solids and other pollutants. The product’s rigid steel frame supports a suspended sediment bag that filters stormwater runoff through a geotextile fabric. The filters are available in curb box, flat rectangular, gutter/V-grate, rolled curb and round inlet filter configurations.
Thompson Pump and Mfg.
Thompson Pump’s 8TSC 8-inch multipurpose Enviroprime trash/sewage pump provides flows up to 2,600 gallons per minute and heads up to160 feet. The pump case can clean debris from the impeller or repair wear items in the pump. The priming system prevents product blow-by from being discharged onto the ground or through hoses.
Gardner Denver Nash
Gardner Denver Nash’s NASH Vectra XL 750 is a liquid ring vacuum pump and compressor. The pump operates at 28.5 inches HgV, and the compressor operates at 30 PSIG. The device features an o-ring sealing, oil lubrication and single-point inlet and discharge connections. The product is made of 316L stainless steel.
