Abstract: The present invention relates to a process for reducing hardness and organic matter concentrations in water. The water being treated is directed into and through an upflow reactor containing a media. As the water moves up the reactor, the media is fluidized. At least one softening reagent is added to the water in the reactor, resulting in an increase in pH and the precipitation of hardness. The precipitated hardness compounds are attached on the media. To enhance the reduction of organic matter in the water, a coagulant is mixed with the water upstream of the softening reactor. As the water flows upwardly through the reactor, the coagulant reacts with organic particles in the water, causing the organic particles to bind and form floc. Downstream of the reactor, the water is subjected to a filtration process that removes the floc containing the organic matter.
