<p>The invention provides a dispenser (10) to dispense, in operation, particulate, soluble chemical agent, by dissolution, from a compacted or compressed form thereof, into liquid that flows along a flow path. The dispenser (10) comprises a body (12) defining a liquid treatment chamber (16), an inlet (22) to the liquid treatment chamber, through which inlet feed liquid can, in operation, continuously be fed into the treatment chamber, and an outlet (26) from the treatment chamber, through which outlet product liquid, containing dissolved chemical agent can, in operation, continuously leave the treatment chamber. The dispenser (10) is configured such that a chemical agent artefact comprising the particulate, soluble chemical agent in a compacted or compressed form is arrangeable in the dispenser, in use, in a predetermined position in which the artefact is exposed to or accessible from inside of the treatment chamber only along a liquid contact surface provided by part of an outer surface thereof, which part extends along an artefact access plane defined in the dispenser in use at the predetermined position, such that liquid which is fed to the treatment chamber through the inlet, in operation, can contact the artefact only along the liquid contact surface and necessarily by passing across the artefact access plane.</p> |
