Membrana-Charlotte (Charlotte, N.C.).   



The rotary table vacuum filter is a continuous filtration unit designed to handle large flow rates. The horizontal orientation of the rotary table enables a thick filter cake to form on the surface. The filter features a uniquely designed cake discharge system, which uses an extraction screw mechanism to remove the dewatered cake from the table and deposits it into a hopper. The filter is an alternative to horizontal belt filters, rotary drum vacuum filters, and filter presses. WesTech Engineering Inc. (Salt Lake City).     


Odor control  

 The ZABOCS® biotrickling filter system is designed to remove odors from large pump stations and wastewater treatment operations. It treats up to 25,000 m3/h (885,551 ft3/h) of odorous air per tower and handles very high hydrogen sulfide concentrations (greater than 500 ppm) with more than 99% removal. The system uses random packed polyurethane foam cubes as the support for biomass growth. Evoqua Water Technologies (Alpharetta, Ga.). 

Filter press  

 The HEI filter press is designed to efficiently dewater solids and process streams in water and wastewater treatment, minerals and mining, coal dewatering, sludge concentration, pigment production, calcium carbonate operations, sugar plants, mash-and-mush-applications in food processing, and also in blood plasma purification. The unit also features both electric and hydraulic components designed to facilitate both filtering and washing. Hoffland Environmental Inc. (Conroe, Texas).   

Filtration system  

The ProCleanse water filtration system (patent-pending) point-of-use water filtration device produces safe drinking water without the need for frequent maintenance, chemical additions, and component replacement. The unit includes built-in safe storage for up to 18 L of clean water, and lasts more than 10 years. Maintenance generally is required only three to four times a year and involves a simple 10-minute skimming process. ProCleanse LLC (Illinois).

Waste caps  

The Smart Waste Caps provide a 95% reduction of harmful substances, such as vapors or gases leaking from waste solvent jerricans due to the use of a filtering cartridge of activated charcoal. The caps are delivered with fittings and ferrules for 1/8 in. and 1/16 in. tubing. JM Science Inc. (Grand Island, N.Y.).



PF series non-spill thermoplastic chemical transfer couplings are designed to meet requirements for closed system transfer of chemicals and other fluids. The couplings can be used with concentrated or diluted industrial chemicals, fertilizers, herbicides, insecticides, fungicides, or pesticides when transferring from bulk storage tanks, returnable containers, applicators, and more. Applications include chemical dispensing systems, agriculture spray application equipment, intermediate bulk containers, pulp and paper, sulfuric acid, pH stabilization, industrial chemical transfer, and water systems. The couplings are manufactured in 0.5-, 1-, and 2-in. sizes. They are available with fluorocarbon, ethylene propylene diene monomer, and Kalrez seals, as well as 316 stainless steel and Hastelloy spring options. A robust connection safeguards the transfer and dispensing of hazardous and aggressive chemicals with minimal spillage. Parker Hannifin Corp. (Minneapolis). 

Remote display 

The Machine-Mountable Remote Display enables users to view the iVu sensor image remotely and serves as a constant monitoring and user programming interface, without interference from electrical noise. The system features industrial metal housing to shield the display from electrical noise, while its cabled connector provides a secure, dependable connection, further enhancing the device’s electrical noise immunity. The system also features an 89-mm (3.5-in.), diagonal, color LCD flat-panel touch screen display and a wide viewing angle — 60° left and 60° right; 50° up and 55° down. Two LEDs on the remote display provide feedback of the remote sensor operation — one for power/error and the other indicating inspection pass/fail. The system is available in five cordset lengths, ordered separately; mounting brackets and stylus are included with the cordset kit. Banner Engineering Corp. (Minneapolis). 


The SQ .2 range, designed for butterfly and ball valve automation, replaces the SG .1 range. The new actuator size in the SQ .2 series more than doubles the torque range. This expansion covers 50 to 2400 Nm. Advanced features and benefits include adoption over a wider torque range without the need for a gearbox. Sophisticated diagnostics and asset management enhancements include additional temperature and vibration sensors. For enhanced positioning accuracy, and an increased number of permissible starts per hour, an SQR version for modulating duty replaces the SGR. Commissioning and operation of SQ actuators are identical to the SA .2 multi-turn range. Both ranges are available with simple AM or microcontroller operated AC integral controls. As a result, controls are interchangeable, and at facilities where both product series are installed, onsite device management is simplified. AUMA Riester GmbH & Co. KG (Müllheim, Germany).
