Koch Membrane Systems Inc.
Reverse Osmosis System
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.
Inge watertechnologies AG
Multibore Membrane
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.
Asahi/America Inc.
Butterfly Valves
Asahi/America’s butterfly valves operate at 110 psi at 70 degrees Fahrenheit. The 16- to 24-inch valves feature molded plastic and wafer style ANSI B 16.5 non-wetted PDCPD bodies with polypropylene or PVDF discs. Industry-standard ISO top flange mounting patterns facilitate gear operator or actuator mounting. The valves are available in EPDM and FKM seal versions.
Clean Way Environmental Partners Inc.
Adsorbent Sponge
CleanWay’s Metal Removal Media removes metals from stormwater, industrial and wastewater discharge. The sponge absorbs heavy metals including zinc, copper, lead and other metallic ions commonly found in water discharge through ion adsorption and filtration processes. The product functions in catch basins, filter vaults and downspout filtration units in both retrofits and new sites. The sponge treats solids, sludge and slurries derived from municipal sewage as well.
Romtec Utilities
Fiberglass Structures
Romtec Utilities’ fiberglass wet wells and valve vaults are designed for pre-engineered pump stations. The underground tanks require no field assembly and are designed to receive influent and discharge pipes, submersible or dry pit pumps and liquid level sensing devices. The units can be positioned vertically or horizontally. The fiberglass construction is not degraded by hydrogen sulfide gas present in sewage and will not break down from exposure to petrochemicals, acids or caustic fluids.
Aquionics
UV Treatment Systems
Aquionics’ OpenLine open-channel UV treatment system is equipped with low-pressure high-output amalgam lamps. The system treats secondary wastewater flows over a wide range of flows and UV transmittances. The AF-3 Series features LPHO amalgam lamps with a maximum output of 500 watts. The units use the full lamp output for high flow per kW system efficiency.
VUEWorks Inc.
Asset Management Software
The VUEWorks 2009 Web-based GIS asset and work management software incorporates condition assessment, risk analysis, valuation, budget forecasting and project cost estimating. The product enables municipalities, utilities and other organizations to track an asset’s condition, minimize failure risk, prioritize expenditures and service delivery of physical assets. Facilities and individual assets, including pump stations, treatment plants, pumps, valves and switches, can be hierarchically structured down to the individual asset level and linked to GIS assets.
MWH Soft
Urban Drainage Analysis
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.
Schroeder Industries
Self-cleaning Filters
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.
Jade Engineered Plastics Inc.
Stock Bearing Shapes
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.
Metrohm USA
Particle-into-liquid Sampler
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.
Enpro Technologies
Polymer Activation System
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.
Campbell Scientific
pH Probe
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.
Mag-drive Pumps
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.
Smith and Loveless
Grit Removal System
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.
