Clean Way Environmental Partners Inc.
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.
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.
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.
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.
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.
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.
KROHNE’s Waterflux 3070 electromagnetic water meter features a 15-year battery life and is suitable for applications where no power is available. The unit’s short inlet and outlet installation requirements allow it to fit in narrow wells and chambers. The device functions as a magnetic-inductive meter, with a low pressure drop. The meter integrates with a GSM module for remote transmission of measurement data and status information.
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.
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
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.
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’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.
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.
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.
