The ELL is the level at which the cost per m3 of constructing, treating and delivering additional water resources equals the operational and capital cost per m3 of leak detection and repair to reduce loss. There are various methodologies for calculating the ELL, but there is increasing concern ...
Second, the fluid height could be a factor for the constant pressure permeability testing setup, while the height of the pressure head in the laboratory is lower than the optimal value20. Finally, the small gap between the permeability testing setup and the periphery of the tested samples also...

For years, our VAUDE Materials Team has been meticulously testing which PFC-free DWR offers the best water beading effect on which materials. The Spray Test is the industry standard for this. In addition, we always test the abrasion resistance and washing resistance of DWR, and how much water...
(12.0)23. Although NaCl is a relatively low-value commodity, the locations of production are often not near consumers and hence transportation costs significantly add to the price. The shipping cost for oceanic, rail, or truck transportation can be an important determining factor when attempting ...
