Hi everyone, Our hospital is being redeveloped and as part of this process we will be moving into new premises in about 18 months. As part of the redevelopment, the engineers are planning for a single reverse osmosis plant with filters, deionizing columns etc capable of delivering 300 L/h, along with a 3000 L reservoir tank. The current plans also includes reticulating the water throughout the laboratory through just two circuits. Our major concern with this configuration is the risk of microbial / algal contamination. I wonder if list members' would be willing to share their experience with similar systems. In particular, what are the risks of contamination? If contamination does occur, how easy or difficult is decontamination?
