Quote Request Inquiry (采购产品): Quote Request Scott, defining the required flows per the below, I see that you have for the 4 inch header at 5000 gallons per day For this we'd see the R/O unit production at 3.5 gpm and a storage tank at appx 5000 gallons. To allow for a day of outage, you might consider a 10,000 gallons storage tank. For your process area water, figuring 3 gpm, the stated tank sizes would only allow for 10 and 17 minutes, respectively. I don't know whether this is what you intended. There are a slew of manufacturers out there, Watts, Remco, Aqua Science, Vortex, Shurflow, Pure Aqua, and I can send RFQs to them if you'd like. Also, you may want to consider whether this is a start-up bloom that will diminish with time, or perhaps a cathodic issue. TR Tom, regarding the large R/O unit you mention and other process area R/O units. Did some checking on our usage for our 4 inch header, and balanced water consumption against our main water bill. Also checked our 6 inch process water consumption, and plant equipment consumption fed from our 4 inch header. 1. Please investigate an R/O unit (or other water quality filter system) fed from our main 4 inch header, that can deliver 75 GPM, 5000 Gal/day, and 100,000 gal/mo at 60 psig. We can give it 100 psig input feed water. Need the cost of filter changes and frequency. 2. Need the cost of 8 R/O units (for our process water area), similar to what you installed, Input pressure 80 to 100 psig, and clean water delivered at 60 psig and 3 GPM. These may need a reserve tank of 30 to 50 gallons?. Scott, I have to run off to make a mtg yesterday, so I though I'd catch up with you via email. We installed and started up the RO unit in the packaging building, and found that it worked quite well, providing clear water. On the down side, in reviewing the set-up and demands at that particular location, it appeared that the sink is used for many uses, which probably outstrip that units capacity. For that reason we elected to install it in a stand-alone configuration, with a side line to feed the drinking fountain adjacent. These units have an inherent bottleneck in the RO filter section, and for that reason are provided a small pressure tank to allow the RO cartridge to work in a somewhat continuous mode making up for the instant demands on the pressure tank. It is reasonable to say that these units are capable of providing on the order 10 gallons of water per shift. That may be variable depending upon the contaminant loading. I'd recommend that the pressure tank be set so that it is appx 2/3 full at system pressure. Tha would put about three gallons in reserve. For a common area sink that may see more demand, it would be wise to investigate the installation of a larger capacity unit.
