Designed to provide water-hammer relief and tight, non-return shutoff for existing flanged piping systems, the Stop-Silent Check Valve AS 54 Model (photo) can be implemented directly into a flanged pipe system without structural or housing alterations. This valve features a cone design that assures tight shut-off to prevent backflow of liquid or gaseous media. The valve has no moving mechanical parts and consists only of two components: a perforated stainless-steel cone and a rubber membrane. This design eliminates water hammer and associated problems of noise and wear, resulting in quiet, noise-free operation. Performance ranges include operating temperatures from – 20 to 180°C and pressures of up to 232 psi. The valve can handle fluid flowrates of up to 10 ft/sec and gas flows of up to 50 ft/sec. — Great Western Supply Co., Houston, Tex.
Raising the reaction temperature achievable with the FlowSyn Continuous Flow Reactor (photo) has considerably widened the scope of reactions that can be performed, according to the manufacturer. Reactions can now be carried out at temperatures up to 260ºC and pressures up to 1,000 psi. High-activation-energy chemistries that may previously have required a catalyst or the use of a microwave reactor are now potential candidates for continuous flow synthesis, with its attendant benefits — better reproducibility and scalability, and fewer problems with unstable intermediates or unexpected exotherms. Other improvements include easier pump priming and refinements to the automated reaction control so that the user can control the amount of pre- and post-plug dispersion phases that are collected with their steady-state reaction product. — Uniqsis, Ltd., Cambridge, U.K.

The cost for sludge treatment — in terms of manpower, equipment and energy — accounts for about 50% of the overall cost of wastewater. Since most end users require that the sludge be transported to another destination, it is important to increase the dry substance (DS). The KemiCond process ( CE, August 2006, p. 13), exhibited at IFAT (Munich, Germany; May 5 – 9), improves dewatering by breaking down the water-retaining structures that are formed ion sludge. The solution is a fully automated continuous process, ensuring smooth operation and minimal workload requirements. The process also decreases operating costs by minimizing the sludge volume. Standard container- or skid-mounted units are available for capacities up to 12,000 ton/yr of DS. — Kemira KemiCond AB, Helsingborg, Sweden
