  • Method and apparatus for recycling R/O waste water
    Patent number: 5282972
    Abstract: Waste water discharged from a reverse osmosis unit served by a water feed line and producing potable water is returned to the water feed line for water conservation purposes. After periodic flushing of the reverse osmosis unit, the flush water may be returned to the water feed line or channelled to a drain. After each cycle of operation, any pressure differential between the water inflowing to and water outflowing from the reverse osmosis unit is relieved.

  • Water dispenser
    Patent number: 5111966
    Abstract: An inverted water bottle, extending upwardly from a water dispenser, refills a container within the water dispenser, which container provides a source of water to a tap. Water from a source periodically refills both the water bottle and the container in response to upper and lower head pressure thresholds. A water processing system may be housed within the water dispenser to purify the water inflowing from the source of water.
