The AnoxKaldnes moving-bed biofilm reactor (MBBR) uses biofilm carrier elements to provide optimal conditions for complete biological treatment or pretreatment in a variety of chemical industry wastewater treatment applications. The process removes biochemical oxygen demand (BOD), chemical oxygen demand (COD), nitrogen, and phosphorous in compact, robust, reliable systems with flexible designs. Depending on the application’s requirements, the MBBR can be used as a stand-alone process, as pretreatment in a more-extensive system, or in the same reactor as an activated-sludge process.

The T791 and T891 compressors are designed for applications that require maximum leakage control when handling toxic, hazardous, and explosive gases. Each piston rod has three sets of packing that form two distinct distance pieces, which serve as barriers to the atmosphere. Since each distance piece has its own line connections that can be separately pressurized, purged, padded, and/or vented, the T-Style compressors provide a wide range of flexibility for controlling external leakage.

The Ultra High Pressure Valve Assembly HP-60, part of the Research Control Valve line, is a 60,000-psi, low-flow control valve engineered for use in high-pressure chemical applications, including research and pilot plants. Its 17-4PH alloy (chromium-copper precipitation hardening stainless steel) construction and solid Stellite inner valve assembly enable it to withstand intense pressure and provide a moderate level of corrosion resistance. The HP-60 can be used for both flow control and as a Class IV shutoff valve.

The PE100 ball valve is a corrosion-resistant solution for below-ground gas, sewer, and water applications where metal ball valves have traditionally been installed. The valve is 50% lighter than comparable metal valves, and it features a two-step planetary gear system to ensure smooth opening and closing, thereby eliminating water hammer. It comes in 1-in. to 6-in. sizes (metric sizes are also available), and units larger than 2 in. are available with an integrated gear box.

The SGi shaft grounding bearing isolator protects bearings from electrical damage as well as from lubricant loss and contamination. It combines the proven technologies of the firm’s GUARDIAN nonsparking bronze labyrinth seal and the AEGIS shaft grounding ring in a single unit. It is suitable for motors controlled by variable-frequency drives (VFDs) that power pumps, fans, high-speed spindles, and other equipment in severe-duty applications, such as those found in the pulp and paper, food, pharmaceuticals, chemicals, water/wastewater, and mining industries.

FluoroFlex biocontainers are the most recent addition to this firm’s One-Touch portfolio of single-use systems. They are made of a new generation, multilayer, coextruded polyvinylidene fluoride (PVDF) film that has been optimized to meet the pharmaceutical industry’s most demanding requirements. They have an inherently pure PVDF product-contact layer that is free of additives, has an extremely low leachables and extractables profile, and provides thermal stability and chemical resistance that exceed the limits of traditional polyethylene-based biocontainers.

The new EP42HT-2FG food-grade epoxy system may be used in a wide variety of applications in the food industry, such as bonding and sealing metals, plastics, rubbers, and other substrates commonly found on food service equipment. The epoxy meets the stringent requirements of FDA CFR 175.300, as well as the NSF/ANSI 51.4.1 (2009) standard for food equipment materials. It features high resistance to chemicals and many solvents, as well as boiling water, fats, and oils, and may be readily used as a coating for storage tanks, bins, hoppers, and other containment vessels.

The TS4000H intelligent hydrogen gas detector provides reliable continuous monitoring and accurately detects hydrogen at 0–500 ppm levels. It features a precision electrochemical hydrogen sensor that has a T90 response of under 30 seconds and experiences minimal zero shift across its operating conditions. In addition, it is unaffected by short-term (= 2.5 min) exposure to hydrogen concentrations up to 50% of the lower explosive limit (LEL).

The 4x4 polarized protective eyewear is for workers who need protection from impact hazards and who face daily glare from light bouncing off flat, reflective surfaces. The 4x4 has been independently tested and certified to exceed the ANSI Z87.1+ and CSA Z94.3 standards. Unlike standard shaded lenses, these lenses contain a special optical filter that absorbs the horizontal component of light, seen as glare, and transmits only the vertical component. In addition to being annoying, glare is dangerous because some light waves can be intense enough to cause permanent eye damage.
