Water Softener Patent
 

Water softener

A water softener employs a vessel, a distributor with a manifold body associated to said vessel and a valve control device. A control unit programs operation of the softener. An actuator unit has a cylinder divided into a first chamber and a second chamber. The actuator unit is adapted to move a spool to define different flow ways, for water. The first chamber communicates directly with a water inlet pipe, and the second chamber communicates with the inlet pipe through a valve and an outlet.

Method and apparatus for recycling sewage sludge utilizing spent water-softener lime

A method and apparatus are disclosed for mixing sewage sludge with spent water-softener lime in a ratio of approximately 10:1 on a wet basis. The mixture is introduced to a rotary pre-dryer kiln and a rotary combuster kiln to kill pathogens. An ash by-product and gases are thereby produced. The ash by-product can be disposed of at much less cost or can be incorporated in a variety of applications such as an aggregate substitute.

Modular water softener system

A water softener system including a hard water flow pipe through which hard water flows, a modular water softener assembly, and a regeneration tank is provided. The modular water softener assembly includes an elongated tube having a first end, a second end, a length extending therebetween, and a predetermined inner volume for storing an amount of water softening particles. The water softener assembly also includes a first end cap coupled to the tube at the first end having a first port in flow communication with the hard water flow pipe and a second port in flow communication with an outlet pipe through which soft water flows. The water softener assembly is supported by the hard water flow pipe and the outlet pipe. The regeneration tank contains a regenerate for regenerating the water softening particles and is in flow communication with the water softener assembly.

Controller and method for controlling regeneration of a water softener

Regeneration controller and method for controlling regeneration of a water softener are provided. The controller includes a water meter configured to output a signal indicative of the volume of influent water received by the water softener. A water-hardness indicator, such as a conductivity meter or ion-selective electrode, is configured to output a signal indicative of a degree of hardness of the influent water. A processor is coupled to receive the respective signals from the water meter and the hardness indicator. The processor is further configured to calculate a value indicative of the total level of hardness removed by the water softener. A comparator is coupled to receive a signal indicative of the quantity of resin capacity of the water softener. The comparator is further configured to receive the value indicative of total hardness to issue a regeneration command based on comparing the resin capacity relative to the value of total hardness.
