摘要： A water treatment and storage system includes a reverse osmosis treatment unit having an untreated water input line, a treated water output line and a bleed water output line. An expandable container, compressed by a spring arrangement, is provided for storing treated water. A container valve, connecting the reverse osmosis treatment unit and the expandable container, terminates the flow of treated water to the container when a predetermined quantity of water has been accumulated therein. The container valve further includes a bleed valve arrangement connecting the bleed water output line and a drain line. The bleed valve arrangement terminates the flow of bleed water to the drain line after the container has accumulated the predetermined quantity of treated water.

摘要： A dual tank storage system is provided having a first generally cylindrical upstanding tank adapted to be positioned either adjacent to or within a second tank of larger diameter. The tanks are in fluid connection and are useful in systems requiring the segregated storage of two fluids until the fluids are mixed and used or in systems where a stored fluid is required periodically to regenerate the contents of another container. A cover is also provided which fits completely over the first tank, when the first tank is positioned within the second tank, and forms a seal with the upper rim of the second tank.

摘要： A valve mechanism is used in combination with a fluid treatment device of the type having a tank defining a treatment bed, particulate treatment material contained within the treatment bed, and a central distribution tube mounted in the bed and terminating in a plurality of distributors which provide fluid communication between the bed and the distribution tube. The valve mechanism consists of a plurality of ball valves, each connected to a different one of the distributors and having unidirectional flow restriction assemblies such that fluid flow in a first direction from the bed to the distributor tube is relatively unrestricted, and fluid flow in a second direction from the distribution tube to the treatment bed is relatively restricted. By providing a substantial flow restriction resistance in each of the distributors conduits, fluid flow through the distributors during a backwashing cycle remains relatively balanced regardless of the variation in resistance due to dirt concentration around each distributor so that the treatment material surrounding each distributor is sufficiently agitated.

摘要： Cation exchange water softeners may be regenerated and, then, the regenerant wastes (brine) recovered, treated, and recycled. The result is a closed system which is ecologically beneficial. The regenerant brine is captured in as concentrated a form as possible and then treated with a precipitant such as sodium or potassium carbonate or mixtures of sodium or potassium carbonate with sodium or potassium hydroxide. Calcium and magnesium compounds are precipitated and the supernatant contains sodium or potassium chloride. These are separated within the brine treatment tank, the precipitate being disposed of as a sludge or sludge cake and the supernatant being recycled to the water softener at the time of further regeneration.

摘要： A circuit for controlling the regeneration cycle of a water softener includes a flow meter which provides a pulse output of a frequency proportional to the flow rate of the water treated by the softener. A predetermined counter, responsive to the flow meter pulse output, provides a first enabling output when a first count is reached indicating that the capacity for treating a normal 24 hour supply of water remains and provides a second enabling output when a second count is reached indicating that the capacity for treating water has been depleted. A 24 hour timer is responsive to the first enabling output to provide a regeneration timer with a regeneration initiation signal at a preselected time during the 24 hour period following the first enabling output. The regeneration timer is directly responsive to the predetermined counter for initiation of regeneration immediately upon receipt of the second enabling signal.
