The innovative and intelligent design of the unparalleled induced draft Air-cooled Condenser - InAIR®, our unqiue and leading position in Wet-to-Dry technology and the ability to install Deluge Cells are only a few of our latest innovations. ALL DRY COOLING SOLUTIONS WET COOLING TOWERS WATER TECHNOLOGIES ENHANCED SAFETY IN FIVE STEPS Read More Published on cpp - chemical production plants processes 03-2018 - Optimised Legionella protection for cooling towers: Poorly maintained cooling towers and evaporative condensers, coupled with old pipe systems or boilers, are one of the breeding grounds that can contribute to the spread of Legionella-containing aerosols. Plant operators can significantly reduce this risk in just five steps. The use of anti-bacterial packing materials of the type supplied by Enexio is a key cornerstone here....

Poor wastewater treatment is one of the biggest enemies of a safe and sustainable water supply all over the world. Next to frugal handling of existing water resources, the treatment of wastewater, sometimes towards future reuse, is important. Unfortunately, the elusive effects of improving water supply through groundwater recharge or surface water must be weighed against capital cost, cost of energy demand, and other variable costs of wastewater treatment facilities. With the costs per unit of energy......

Among other aspects, the effective surface depends on the interfacial tension between the fluid and the material properties of the surface of the transfer elements. The influence of the interfacial tension on the effective surface has been thoroughly analyzed, and corresponding empirical equations have been set up. It is known that water, in particular, because of its high surface tension wets plastic surfaces very badly. In some fundamental works this fact is sufficiently taken into account by material properties. For film type mass transfer elements in plastic it leads to a calculated degree of wettability of less than 50 % of the possible geometrical surface at usual flow......

The incorporation of several physical effects and boundary conditions and possible ways of measuring or estimating them will be introduced also. Finally, a best practice guide and a checklist are offered to ease up future simulations for......

Due to installing best available technology of cooling fills a decrease of cooling water temperature and additional power output can be generated. The following consideration shows options of improvement and takes a look at......

The impact of these two factors will be discussed in this paper based on different testing results for polypropylene. Additionally a simplified viscoelastic model has been derived from that data to get a general idea for the engineering of plastic fills.... [read more about Time and Temperature Dependent Mechanical Behavior of PP Fills] MECHANICAL BEHAVIOR OF POLYMER FILLS Read More Published on CTI Biography of Technical Papers - Fills: This paper will outline the mechanical properties of polymer fills and discuss the influence of different parameters (like design, foil thickness, PP vs PVC) as well as the influence of the boundary in cooling tower surrounding.... [read more about Mechanical Behavior Of Polymer Fills] MODULAR SPLASH FILL Read More Published on CTI Biography of Technical Papers - Fills: This paper will discuss the benefits and thermal performance levels of modular splash fills vs. common film fill mediums in cooling towers and the change of those levels over the useful life of the fill. We will also examine the typical life cycle, durability and maintenance of modular splash fill. Last, we will review the advantage from being able to run at higher cycles of concentration, assistances for applications involving the use of gray water for makeup and for implementing in water conservation projects, which is vastly becoming a larger conversation topic due to the constant push from governing organizations....

Whereas this is true for standard polyolefin materials, modern polypropylene products with high efficient flame retardant additives can even beat the good fire properties of normal PVC.In this study film fills for cooling towers made of PVC and of a flame retardant PP are tested by several different methods and international standards to evaluate the actual performance of these two materials....
