Abstract
An improved method and apparatus for blending process materials. Preferred embodiments of the present invention are directed to a process material contacting system to increase wetted surface area for liquid contact as well as increase forced convective mixing efficiency of the liquid mixture. Use of a novel process material contacting apparatus allows one solid feeding element to serve multiple process material tanks, thus reducing overall system costs and decreasing set-up time/process variability while increasing operational efficiency. According to a preferred embodiment of the present invention, rather than adding a process material to a volume of liquid held in a blending tank, the added process material is remotely blended with the liquid outside the process material tank.
