Apparatus, method and system for desalinating water

A system comprising:

• a. an inlet device having a tubular section that is at least partially in water;
• b. a plurality of pumps located on a skid for moving the water through the tubular section on the inlet device to water purification equipment located on a plurality of skids;
• c. a plurality of filters located on a skid that is connected to the inlet device, the plurality of filters are connected to the inlet device to selectively filter particles in the water;
• d. a plurality of reverse osmosis filters on a skid for separating contaminates from the water;
• e. a plurality of energy recovery devices located on a skid for recapturing pressure energy from water running through the reverse osmosis system and returning the pressure energy to move additional water through at least a portion of the plurality of skids, at least one energy recovery housing device for holding the plurality of energy recovery devices on a skid, wherein the plurality of energy recovery devices on a skid can be removed and inserted and attached to connections on the housing that align and correspond to connections on the plurality of energy recovery devices on a skid, and wherein at least one connection on the housing that align and correspond to connections on the plurality of energy recovery devices on a skid is a fluid line connecting the plurality of energy recovery devices on a skid with the energy recovery housing device;
• f. at least one reverse osmosis housing device for holding the plurality of reverse osmosis filters on a skid, wherein the plurality of reverse osmosis filters on a skid can be removed and inserted and attached to connections on the reverse osmosis housing that align and correspond to connections on the plurality of reverse osmosis filters on a skid, and wherein at least one connection is a fluid line connecting the plurality of reverse osmosis filters on a skid with the reverse osmosis housing device;
• g. a discharge device for discharging the brine from the plurality of reverse osmosis;
• h. a plurality of sensors, the plurality of sensors comprising at least one sensor connected to the inlet device, at least one sensor connected to the plurality of filters, at least one sensor connected to the plurality of reverse osmosis filters, and at least one sensor connected to the plurality of energy recovery devices;
• and
• i. a control device that is connected to the plurality of sensors and can operate the plurality of filters, the plurality of reverse osmosis filters, the plurality of energy recovery devices in a coordinated manner.
