Abstract
The utility model discloses an energy saving type reverse osmosis water treatment apparatus, comprising a pre-filtering device, a solar heat collector, a heat insulation water tank, a frequency-conversion controller, a high pressure water pump, a precise filter, a reverse osmosis component and a flow transducer. The apparatus is characterized in that the flow transducer is mounted on the total penetration water pipe of the reverse osmosis component; the frequency-conversion controller controls the rotation speed of the high pressure water pump through the signal of the flow transducer.
