<p>The invention relates to an apparatus for neutralizing acidified water by means of limestone or a similar basic material. It provides an apparatus which can be used for increasing the pH-value of water coming from wells or the like and feeding just one or a few households. According to the invention there is in the water supply system interconnected an apparatus having a fluidization chamber for solid basic particles the size of which is within the approximate range 1-10 mms. The water enters the chamber at the lower part thereof and flows upwards. The crosssection area of the chamber increases in the flow direction so that the heaviest particles will float near the bottom and Lighter particles at higher levels. A funnel-shaped storage chamber is located above the fluidization chamber and does successively replace consumed material.</p> |
