What is the Footprint for an RO System

While the footprint of an RO system will obviously very with size of the system, there are some generalities that can be made. The length of the RO system depends on how many membrane modules are in series in the pressure vessels. Table 17.1 lists the approximate size of an RO skid as a function of the number of modules in the pressure vessels. Note that sizes may vary depending on the manufacturer. 

Additionally, there are work zone areas that should be allowed for in the plant layout of the RO skid. At each end of the RO skid, a zone of a minimum of 4 feet (6 feet is best) should be allotted for loading and unloading membrane modules. The front side of the skid should have about 4 feet allotted for pump maintenance and access to the controls and instruments. The backside of the skid requires no access and the skids can be placed 1 to 2 feet away from adjacent equipment.
