The PURO PRO is a modular reverse osmosis filtration system for 
the reduction of Total Dissolved Solids (TDS) from water.  The 
system consists in six (6) high-performance reverse osmosis 
membranes.  The system is designed to operate with a pressurized 
(40 to 90 psi) feed and a vented storage tank for collection of the 
product water.  An inlet normally-closed solenoid allows pressurized 
water to enter the system whenever it is activated by the level float 
which is installed in a water collection tank.  See Figure 1.  The 
modular assembly is constructed of non-corrosive Noryl

polypropylene, and FRP materials.  The reverse osmosis system is 
rated at a maximum working water pressure of 90 psi.  The system 
has a fixed inlet flow control, and an adjustable drain restrictor control 
for achieving maximum efficiency.
