Delta Pure HC Series High-Capacity Wound Filters provide excellent filtration for fluids with a wide particle size distribution. The HC Series filters are wound with two zones in order to provide longer filter life with challenging fluids. A more open pre-filtration section serves to protect the downstream section and remove larger particles while a tighter final filter section provides removal of smaller particulates. The rating of each zone is specified in order to provide a filter uniquely tailored to process requirements. Micron ratings are available from 0.5 micron to 200 micron. Optional core covers allow added contaminant removal assurance. Cartridges…

By Rick Andrew For the last few years, one of the hot topics in the drinking water space has been that of PFAS. PFAS, the accepted acronym for per- and polyfluoroalkyl substances, includes a large number of chemically related contaminants. These contaminants are entirely synthetic and have been used for various industrial purposes including waterproofing of fabrics, manufacturing of non-stick cookware, as well as constituents of firefighting foam. One unfortunate reality of chemicals with the structure of PFAS is that they are extremely environmentally persistent, meaning that they break down in the environment only very, very slowly. As such, they…

By Emma H. Peterson In 2001, Tina Donda joined the water treatment industry as an assistant to a lab director. Her intent was to leave when she was able to start a family, and as a lover of science and the lab atmosphere, she thought it would be a great way to pass the time. Fast forward 20 years and three kids later, Donda is still here rocking the drinking water treatment certification world. She has served as Vice President of International Association of Plumbing and Mechanical Officials (IAPMO) for the past five years. IAPMO is a trade organization dedicated…

By Tal Fabian Water scarcity is a subject of major concern worldwide due to the depletion of clean water sources and growing population concentrated in urban areas. This places wastewater treatment and reuse in the spotlight as a sustainable solution for water reclamation, while protecting water sources from pollution. The need for advanced wastewater treatment schemes is on the rise, due to de facto indirect potable reuse that occurs when treated wastewater effluents are discharged into streams that serve as a water source for a downstream water treatment facility. Water reuse treatment schemes There are two main treatment schemes that…

By George Diefenthal and J.R. Cooper, PhD Introduction Many designers and operators have a love-hate relationship with wipers. While they can address some issues of quartz fouling and reduce service intervals, they also result in challenges for sizing UV equipment, monitoring its performance and supporting the additional maintenance effort required to keep them operating properly. Wipers were introduced into UV chambers to address the fouling of the quartz sleeves, which is defined as the reduced transmissivity of UV light from the lamp, through the quartz sleeve and into the water column. The main causes of this fouling and suggested limits…

The three-year revision cycle of the 2021 plumbing codes are well underway. All proposals have been presented to the committees of the International Association of Plumbing and Mechanical Code Officials (IAPMO) for the Unform Plumbing Code (UPC) and the International Code Council for the International Plumbing Code (IPC). Now that the debate is underway for the 2024 code cycle, let’s review a couple product requirements in accordance with the 2021 UPC. At this time, several authorities having jurisdiction (AHJs), including states, counties and cities, are beginning to adopt the 2021 versions of the codes. In this article, we will review…
