And although turbidity can be unsightly and distasteful, or even destructive of sensitive equipment, there is little hope of a massive infrastructure overhaul in most areas. The result is a boom in point-of-use (POU) filtration to purify water, ranging in sophistication and cost from activated carbon to cartridge filters to POU membranes.
Increasingly, engineers and developers are seeing the value of point-of-entry (POE) filtration as well, which delivers cleaner water to users in their hospitals, hotels, and luxury high rises, and helps POU filtration operate with added efficiency and effectiveness. Daily hydrant challenges Sometimes, such as the case of a hotel guest expecting to drink pristine water from their room’s bathroom tap, it’s a matter of convenience. In other cases, such as a dialysis unit in a hospital faced with turbid feedwater, it’s much more serious.
Richard Kulinski, a plumbing/fire protection engineer with Bard, Rao + Athanas Consulting Engineers, a New York Citybased engineering firm with research and healthcare clients around the country, has several hospital and laboratory construction projects in the works. In those projects, POE filtration is specified to combat total suspended solids (TSS) coming from aging, overtaxed infrastructure in urban areas that have seen a tremendous amount of development in recent years.
