WEFTEC Show Preview

| By Mary Page Bailey

WEF LOGOPresented by The Water Environment Federation (Alexandria, Va.; www.wef.org), the Weftec 2016 conference and exhibition will take place Sept. 24–28 at the Morial Convention Center in New Orleans, La. In addition to an exhibit hall featuring nearly 1,000 exhibitors, this year’s event will include 130 technical sessions and 29 educational workshops. This Show Preview highlights a small selection of the water-related products and services that will be on display inside the Weftec 2016 exhibit hall.

A self-cleaning filter with automatic solids recovery

Spiral Water Technologies

Spiral Water Technologies

This company has expanded the application of its Automatic Self-Cleaning Filter and Solids-Recovery System (photo) beyond filtration into the realm of solids management. The patented water filter provides filtration in the 10–100µm range, and can achieve continuous, fine filtration even in water with ultra-high and variable total suspended solids up to 25,000 ppm. The integrated solids-recovery system utilizes proprietary sensor technology that measures solids buildup electronically and activates an automatic purge valve to remove it. This enables simplified recovery of solids and product in industrial process streams, and a major reduction in diluted wastewater that can significantly lower cleanup expenses. Booth 3129 — Spiral Water Technologies, Inc., San Rafael, Calif.

 Gas-tight foam basins for sewage applications

TOPP Industries

TOPP Industries

The Evolution E-Series Basin (photo) is a maximum-durability structural foam basin that is resistant to cracks and dents. The E-Series features self-tapping lags for cover attachments and 180-deg dual, raised flat pockets for a tight inlet seal. All basins are gas-tight for sewage and radon-mitigation applications. E-Series basins are available in diameters up to 30 in., with foam covers up to 24 in. Additionally, epoxy-coated steel and non-skid fiberglass covers are available. The basins can accommodate 4-in. composite inlet hubs and require no external stacking ribs that may interfere with the use of external filtration configurations. Booth 2207 — TOPP Industries, Inc., Rochester, Ind.

An interface between sensors, controls and automation

GF Piping Systems

GF Piping Systems

The new Signet 3-0486-D Profibus Concentrator communication protocol (photo) allows users to connect multiple Signet sensors, actuated valves and other products to their automation system, thereby reducing wires, cables, setup time and maintenance. The device meets UL, CSA and IEC61010 safety approvals and is certified by Profibus International. The Profibus Concentrator can interface six sensors, plus an additional 4– 20-mA current loop input and output channel with proportionally controlled actuated valves or other 4–20-mA devices.

Drain large tanks without mechanically installed nozzles

Assmann

Assmann

The Full Drain Outlet (FDO) assembly (photo) drains tanks of 2,500 gal and larger without mechanically installed nozzles. The FDO assembly is suitable in applications where heavy solids or salts can accumulate in the bottom of tanks. The assembly virtually eliminates the need for confined-space entry and difficult maintenance work. The assembly is equipped with a metallic molded insert that is available in 316 stainless steel, titanium and Hastelloy C-276, allowing for storage of a wide range of chemical types. The FDO also features a polyethylene flange adaptor that can be removed so that tanks can be installed on flat surfaces without a concrete pad. Booth 2657 — Assmann Corp. of America, Garrett, Ind.

Single-stage turbocompressors with a large turndown range

This company’s STC-DO single-stage, direct-drive turbocompressor utilizes a high-speed motor with the impeller mounted directly on the shaft. The compressor features turndown to 35%, which is said to be the widest turndown range in the industry. Tailored for use in wastewater treatment in both industrial and municipal settings, the compressor features a flow capacity range of 1,000 to 13,000 m3/h, and differential pressures up to 1.1 bars. The machine is 100% oil-free and comes with electrical filters as standard. The turbocompressor also boasts low noise production with no pressure pulsations. The company’s DualPoint control process allows for independent regulation of the flow and head of the compressor, providing efficiency even at off-design conditions.

Flexible and resilient MABR modules

GE Power, Water & Process Technologies

GE Power, Water & Process Technologies

The ZeeLung membrane aerated biofilm reactor (MABR) utilizes a gas-transfer membrane that is specifically designed for MABR applications. Hollow-fiber oxygen-permeable gas-transfer membranes are distributed longitudinally around the circumference of a yarn-based reinforcing core, resulting in a flexible, yet resilient module (photo). The top header delivers and distributes air to the inside of the fiber lumens, and exhaust gas is collected in the bottom header. Modules are installed in cassettes for deployment in bioreactors. ZeeLung cassettes can be installed directly into a bioreactor, and have little effect on existing equipment and operations. In the low-energy process, oxygen is delivered at an efficiency that is said to be four times greater than fine-bubble aeration processes.

Sanitary strainers that can handle a wide viscosity range

Newark Wire Cloth

Newark Wire Cloth

This company’s product line of SaniClean strainers (photo) is engineered to suit specific requirements in a wide variety of both batch and continuous processes. The strainers are manufactured in single and duplex configurations and can be easily integrated into existing or new piping layouts. The standard material of construction for the SaniClean line is 316L stainless steel, but other corrosion-resistant alloys are also available for handling highly corrosive materials. Rugged construction allows the strainers to withstand rigorous production cycles. Capable of coarse straining and fine-particle filtration, the strainers are available in varying capacities to handle a broad range of viscosities. Booth 7944 — Newark Wire Cloth Co., Clifton, N.J.

Analytical sensors with integrated transmitter technology

Krohne

Krohne

Smartpat is a family of two-wire loop-powered analytical sensors (photo) with integrated transmitter technology for direct connection of the sensors to process-control systems. All sensors are digital and can be calibrated or recalibrated offline in a laboratory under controlled conditions. For offline calibration, the sensor can be connected directly to a PC running the same FDT/DTM frame applications (for example, PACTware) as applied in common asset-management systems, using a USB interface cable for bi-directional HART 7 communication and power supply. According to the manufacturer, this is a significant improvement over other analog analytical sensors that must be calibrated onsite together with the transmitter, even if installed at remote or difficult-to-reach measuring points, which can also cause sensor calibration to trigger false values in the process-control system. Booth 3807 — Krohne, Inc., Peabody, Mass.

Control dissolved gases without the use of chemicals

Liqui-Cel Membrane Contactors are compact and modular devices that control dissolved gases in liquids without chemicals. They are capable of achieving purity levels of less than 1 pbb O2 and less than 1 ppm CO2. Reducing chemical usage can decrease the blowdown frequency due to scaling from chemical deposits. CO2 removal can improve efficiency and reduces chemical consumption in mixed-bed or electrodeionization (EDI) technologies. Booth 7113 — 3M Membranes, Charlotte N.C.
