Stormwater BMP

Eliminate E. coli, fecal coliform, and enterococcus before they enter sewers. Ultra-Urban Filters feature a recyclable non-toxic, non-leaching polymer-based sponge that has delivered average kill rates of more than 75% for the cities that have tested them at airports, high-traffic intersections, and catchbasin inlets. Equally effective in flowing or pooled water, the filters also absorb gasoline, oil and grease, and sediment. EPA-approved as a National Pollutant Discharge Elimination System (NPDES) best-management practice. AbTech Industries Inc.

MBR module

This membrane bioreactor module features 16,146 ft2 of membrane area, making it suitable for large-scale MBR projects. Modules with 323, 2530, or 5382 ft2 also are available. Module features include an optimized permeate extraction manifold and enhanced air supply lines, which reduce the number of piping connections required during installation. A single header with hollow fibers fixed only at the bottom, with free-floating upper end, eliminates buildup of hair and fibrous materials. Koch Membrane Systems.

Impact cutter

The Paikert/Intruder is a low-speed, high-torque impact cutter for clearing blockages in pipes with diameters from 4 to 32 in. The tool can get rid of hardened concrete, chemical deposits, protruding taps, heavy root growth, or other blockages and obstacles. A carbide blend cuts through concrete, hardened deposits, taps, etc. For roots, use a hardened-steel sawtooth blade. NozzTeq Inc.

Long-life meter battery

SmartMeter SM700 meters—with capacities of 20 or 30 gal./min.—can now be fitted with a replaceable battery that lasts 15 years or longer. When used to replace a meter's existing battery, it can extend the meter's service life to beyond 30 years. The new battery, when paired with the meters' high degree of accuracy, provides significant overall cost savings. Severn Trent.

Plant security evaluation

The company provides security evaluations for all aspects of a water-treatment plant: IT, physical plant, chemical storage, personnel safety, and industrial control. After a vulnerability assessment review, the company makes security improvement recommendations, focusing on low- and no-cost solutions. It also can develop geographical information systems for manhole covers, valves, pumps, and security systems. Revere Control Systems.

Root-supporting stormwater cell

The Silva Cell supports loads from traffic on the pavement above while providing uncompacted soil volumes for growth of large trees and onsite stormwater management below ground. Stormwater enters through pervious pavers or other drainage systems. The soil in the cell offers underground bioretention for filtration, storage, and recharging runoff. It is suitable for use beneath sidewalks, parking lots, playgrounds, and other areas. Deep Root Partners L.P.

Bypass pump

The DV 300i is a 12-in. pump designed for bypass pumping applications. It can handle solids up to 3½ in., flows up to 6900 gal./min., and heads up to 197 ft. With a high degree of fuel efficiency, the unit can move more liquid at a lower unit cost than competitive models. Rain For Rent.

Particle imaging

The FlowCAM WW is designed to monitor the biological makeup within a wastewater treatment plant's secondary system. The automated unit enables operators and laboratory technicians to check if treatment basins are within the optimum level and makeup of microbes, then quickly take any required remedial action. The high-speed instrumentation takes high-resolution images of microorganisms and inorganic solids; images and corresponding data sets are saved in a digital library. Fluid Imaging Technologies Inc.

Multigun valve

The MGV15-3000 multigun valve for high-pressure water jetting operates at high flow and can be repaired in the field, in less than five minutes. A multi-gun valve permits the use of multiple water-jet lances from a single pump unit. Designed for operating pressures from 4000 to 15,000 psi and flows up to 30 gal./min. per side, the valve features a screw-in cartridge seal that can be used interchangeably with the company's lances and foot-control valves. NLB Corp.

Electromagnetic flowmeters

The Tidalflux IFM 4110 PF and IFM 4210 PF flowmeters measure the volumetric flowrate of electrically conductive liquids in partially filled pipelines. Matched with a capacitive flow-level measuring system, the products are built into the wall of the measuring tube to provide accurate measures with levels between 10% and 100% of the pipe's cross-section. Benefits include high accuracy, rapid response time, ease of installation, and reduced maintenance. Krohne Inc.
