Solution Colder Weather RO Pressure Problems

We recently had a client that had scheduled a water pole service that required execution on a specific week. It turned out that the scheduled week we encountered temperatures that are not really compatible to an 8 stage RO filter system. Generally, you want temperature in the upper 50's or greater due to the fact that at lower temperatures the RO membranes tend to constrict resulting in lowering water pressure. We knew we could rig up a water tank and pump system that would only require temperatures above freezing to operate. However, we didn't have time to get that all rigged up so we needed a quick inexpensive solution. After some research we determined that we would employ a pump booster into our existing system. We simply place the electric pump in line of our water source. This bumped our water pressure an additional 40 psi. With this boost we could now produce pure water at 70 psi with no problem at 45-55 degrees. Later we will incorporate this into a water tank pump system with pre filtered water perhaps in spring. If you've encountered similar issues here's a link to jracenstein's window cleaning supplies that has the pump we used.
