Reaction Tower for Hypochloride acid

When preparing the chlorine solution in the chlorine gas ejector, in addition to hypochloric acid (HClO), hydrochloric acid is produced as well in the motive water.

Installation and operation
The reaction tower is to be installed directly after the ejector outlet in an upright position. A pressure loss of about 0.2 bar in the reaction tower has to be taken into consideration for the ejector configuration. Besides, it must be ensured that the reaction tower is always filled sufficiently with granulated marble (at least 30%), which is decreasing because of the aforementioned reaction.

Marble consumption
The marble consumption can be determined as a function of water hardness, flow and chlorine gas volume using the following formula.
