A system and method for dispensing an aqueous solution to one or more points of use is provided with one or more pressure vessels that are adapted to be charged with pressurized gas to drive the aqueous solution on to the point or points of use. A humidifier is also employed to humidify the pressurized gas to at least inhibit the pressurized gas from evaporating the moisture from the aqueous solution. In such manner, changes to the make up of the aqueous solution are avoided. Such changes can produce caking and/or changes in chemical properties found in pressure vessels used in dispensing slurries.

Dispensing system and method for dispensing an aqueous solution

An apparatus and method for producing a slurry from a slurry concentrate in which streams of slurry concentrate, de-ionized water and oxidizer are pumped to form three pumped streams that are brought together to form a mixture. Homogeneity is promoted within the mixture by such devices as a static mixer and an in-line mixer of special design. The resultant homogenous stream is then pumped to dispense pressure by a dispense pump to produce a dispense stream. Part of the dispense stream, preferably about fifty percent, is recycled back to a junction at which the pumped streams join to further promote homogeneity of the slurry. For such purpose a flow network is connected to an outlet pump and such flow network is branched so as to have a dispense leg from which the dispense stream issues and a recycle leg connected to the junction for recirculating the recycle stream.
