None of the water vending units that we produce include reverse osmosis water filtration. There is a very sound reason for not doing so. Generally, the only times this type of treatment is needed is when the total dissolved solids (TDS) count is above 500 parts per million. If the vending water machine is to be hooked up to a water source that has already been treated by a public utility or water treatment plant, then the amount of TDS has already been reduced below this threshold.As long as your source of water has already received treatment then using a reverse osmosis water filtration process is simply a case of overkill, or, solving a problem that you don’t have. There will be situations, however, when it becomes necessary to use an RO system. If the source of the water going to your water vending machine has never been treated then the RO membrane will remove a significant number of dissolved minerals. In order to reduce maintenance of the membrane an RO system requires pre-filtration using a sediment and carbon filter to remove solid particles and chlorine and to extend the life of the membrane. It will take but a few moments to hook up an RO system to supply our water vending units without the need of any special tools or equipment.
