Show Preview: Weftec 2019

| By Mary Page Bailey

The 92nd annual Water Environment Federation Technical Exhibition and Conference (Weftec; www.weftec.org) will be held September 21–25 at the McCormick Place Convention Center in Chicago, Ill. Weftec features an extensive lineup of technical presentations focused on best practices and new technologies in water and wastewater treatment, as well as an exhibition hall that will be open from Sept. 23–25 and will feature more than 1,000 exhibitors who will showcase the latest equipment used in water-treatment processes. The conference program consists of over 140 technical sessions and over 30 workshops, as well as facility tours. The following preview highlights a small sampling of the products and services that will be displayed at Weftec.

Scaletron Industries

Use these scales with corrosive materials

This company offers a wide range of 150-lb cylinder scales (photo) that are used for weighing and monitoring the usage of corrosive chemicals, including liquefied gases, such as chlorine, sulfur dioxide, ammonia, hydrogen chloride and carbon dioxide, which are packaged in cylinders up to 12 in. in diameter. The scales feature a corrosion-resistant construction, and are available with digital and mechanical components. Single- and multiple-cylinder models are available. The scales’ low-profile platform design increases safety and ease of cylinder handling. Booth 5248 — Scaletron Industries Ltd., Plumsteadville, Pa.

Dräger

Integrated gas detector makes laboratory analysis portable

The X-pid (photo) is an intrinsically safe gas detector that can detect benzene, butadiene and other volatile organic compounds (VOCs) in a matter of seconds and weighs less than 3 lb. Designed for users who frequently test for hazardous toxic substances, the X-pid product line integrates gas detection capabilities via photoionization detector (PID) and gas chromatography (GC) technologies, combining robust analysis with portability. The integrated PID provides measurement in the low parts-per-billion (ppb) concentration range. The PID/GC gas detector also comes with an explosion-proof handheld control unit and mobile app that enable intuitive handling and control. The device’s sensor unit compiles measurement values and sends them via Bluetooth to the control unit. Booth 6327 — Dräger, Inc., Houston

GF Piping Systems

 

Piping systems for safe conveyance of hazardous liquids

The Double-See vinyl double-containment piping system (photo) is an easy-to-install pressure-rated system with a primary (inner) and secondary (outer) pipe designed for safely transporting hazardous liquids. With the Double-See system, both primary and secondary pipes are cut to the same length and can be joined simultaneously. This saves significant time and prevents potential mistakes caused by staggered pipe-cut measurement errors, according to the manufacturer. Other important features include a unique-to-the-market 3-D thermal-expansion compensation centralizer, and a valve-in-valve design that provides full pressure rating in the containment piping.

Assmann Corp. of America

These tank assemblies simplify draining

This company’s patented Full Drain Outlet (FDO) assemblies for tanks of 2,500 gal and larger (photo) allow tanks to drain without the need for mechanically installed nozzles. The full drain assembly should be utilized where heavy solids or salts can accumulate in the bottom of the tank, thus creating difficult maintenance work. This assembly virtually eliminates the need for confined-space entry, says the manufacturer. Furthermore, the company also offers double-wall tanks for primary and secondary containment of hazardous and corrosive chemicals in capacities from 20 to 8,850 gal.

Kaeser Compressors

Improve blower performance with this management platform

The Sigma Air Manager (SAM) 4.0 is an adaptive controller platform for improving air generation and treatment. The 3DAdvanced Control functionality analyzes all operating data on an ongoing basis, simulates alternative actions and calculates the optimal combination of compressors, blowers or vacuum units to meet demand. SAM 4.0 not only reduces switching losses, but also takes into account various compressed-air system parameters and uses the gathered information to calculate the optimum performance values. SAM also continuously fine-tunes the system in order to achieve energy efficiency (energy management in accordance with ISO 50001). Secure remote monitoring is offered so that users can view system performance from any PC. As facilities grow, SAM systems can be easily expanded with a simple software update, meaning that there is no need for investment in new hardware.

Asahi/America

This piping system can handle aggressive chlorinated media

Made from a specially formulated polyethylene (PE) resin, the Chem Proline Advanced PE piping system (photo) is designed to handle very aggressive chemicals, and is NSF 61-G certified. A single-wall piping system well suited for use in water treatment applications, Chem Proline includes pipe, fittings, valves and accessories. Chem Proline is UV-resistant, can be installed above or below ground, and is thermally fused using butt, socket or electrofusion joining methods, which eliminates leak paths at the joints. Chem Proline is said to be the only polyolefin piping system able to handle certain chlorinated or corrosive media, such as sodium hypochlorite, sodium hydroxide, caustic soda and low-concentration acids. Chem Proline’s pH capability ranges from 1 to 14, with pressures up to 150 psi and temperatures up to 140ºF. Booth 8104 — Asahi/America, Lawrence, Mass.

HRS Heat Exchangers

Use these scraped-surface heat exchangers to decrease fouling

The design of the Unicus Series of reciprocating scraped-surface heat exchangers (photo) is based on a traditional shell-and-tube heat exchanger with scraping elements inside each tube. The reciprocating movement of the scrapers mixes the fluid while cleaning the heat-exchange surface. This action keeps heat transfer high and reduces downtime. In addition, the scraping movements introduce turbulence into the fluid, which increases levels of heat transfer. This design makes the Unicus Series appropriate for industrial or hygienic applications where fouling or low heat transfer is a limiting factor. The gentle movement of the scrapers allows the system to be used with delicate products without destroying the product integrity. Booth 8512 — HRS Heat Exchangers Ltd., Watford, U.K.

Poly Processing

Integrated flange assemblies make these tanks easy to access

This company offers the Integrally Molded Flanged Outlet (IMFO) system for its full-drain polyethylene (PE) tanks, in which the flange is molded into the tank during manufacturing, rather than being introduced post-production as an insert. IMFO fittings are constructed in the same material as the tank, creating a homogenous unit, and since the fitting is integrated with the tank itself, there is no added stress on the lower sidewall. The one-piece IMFO construction means that the flange can be installed below the knuckle radius at the bottom of the tank’s sidewall. The entire flange system is external to the tank, providing easier access to hardware than with metallic inserts. The sloped-bottom design is recommended for processes that handle heavier materials, including fats, oils, greases or sludge. With this tank configuration, there is no need for confined-space entry for cleaning activities, since the sloped-bottom tank can be cleaned from the top via a manway, or with a spray ball.
