The On The Go RO system is designed specifically to fill non-pressurized containers with RO water. The receiving container might be your RV fresh water tank, 5 gallon jugs, etc. We even provide a float switch so that the system will sound an alarm and stop producing water when your container is full. It is not intended as an under sink system with a faucet mounted by the sink, at least not without additional parts (it is perfectly capable, if desired). Our system is designed to also work with low or no water pressure, or even to draw water up from a natural source (like a stream) by including a “booster pump”. This pump also ensures higher water pressure on the membrane, increasing the water production. We also include an “accumulator”, which is a small pressure tank. This serves to extend the life of the booster pump, and also will allow you to get significantly longer water production out of your RO membrane and thus replace the membrane less often. 

Specifically, our system gives you indications of your filter and membrane condition so that you don't unnecessarily replace those before required to do so. The system includes two RED warning LED's. One will tell you if your Sediment+CTO filter is clogged and needs to be replaced (this feature is disabled when using the low/no pressure bypass switch) and the second red LED warning lights when your RO membrane is reaching the end of it's life (see explanation of this LED next to it on the control panel). Since our system is portable, and may be used on many different water sources, you will probably want to keep a couple of spare Sediment+CTO filters, and one extra membrane. If using a “normal” city-water source, you may get over a year of use on these items. This of course depends on the amount of water you process and on the quality of the water source - where clearly operating our system 24/7/365 will go through the filters faster than a system used to fill a 100 gallon tank each week. 

You can absolutely use our system to process naturally occurring water from sources like wells, rivers, lakes, streams, etc. However, you do need to ensure a few things first – the water source needs to be clear or nearly clear. If you have a less clear water source (or TDS > 800), then we recommend you use an external dedicated “sediment filter” that is rated at 5 microns (or less). If you don't do this step on non-clear water, then our system's Sediment+CTO filter will become clogged sooner and need to be replaced. Additionally, our system includes a Flow-thru valve that you will want to open. This allows for extra self-cleaning flow of water over the membrane to help remove the surplus contaminants of the less clean source water. Even with higher TDS water, the system will still provide quality RO water, but the filter and membrane will become clogged faster. This system is capable of purifying slightly brackish (salty) water, but the saltier it is, the faster the membrane will clog. Since salt molecules bond with water molecules (and so don't fit through the RO membrane's holes), the purified water output flow (BLUE tube) is reduced.

One upgrade option for purchase with our system is an installed 2 point total dissolved solids (TDS) digital meter that shows both the source water TDS in parts per million (PPM) and the output RO purified water in PPM. This is helpful to determine the quality of the source water, and to ensure your membrane is not damaged (not usual). Typically, the output RO water (BLUE tube) will read 10-30 ppm, when theTDS of the water source (RED tube) is 800 ppm or less. RO membranes are rated in “rejection rate”. With a 96% RO membrane you can expect the membrane to reject 96%+ of impurities. If your source water measures 500ppm, then 96% would be an output reading of 20ppm. The brand membranes we installed for you we have actually tested, both for the rejection rate, and the flow rate, in this case 150 GPD (gallons per day). The GPD flow rate will decrease over time as the membrane becomes clogged (even with the self-cleaning flow of discharged water from the YELLOW tube.) Another factor that effects the rejection rate and flow rate (GPD) is the water temperature. The warmer the water - the greater the GPD, with slight reduction in rejection rate. With cold water (40-50 degrees), expect the GPD number to be lower.
