ABSTRACT:
An apparatus and method for mixing and dispensing chemical solutions are disclosed. The blending unit (11) includes a manifold (38) having a plurality of chemical inlet ports (39), a water inlet port (45), and an outlet port (46). A plurality of pumps (43) and valves (41) are associated with the chemical inlet ports (39). The outlet port (46) is connected to dispensing outlets (25, 29) for dispensing the chemical solutions and water into a container 16. The apparatus (10) also includes a quality control systems, including a conductivity cell (50), a weight measurement station (26), and a volume flow measurement device. The apparatus (10) also includes an electronic control unit (70) associated with the pumps (43) and valves (41) to operate them in response to a pre-selected volume, sequential combination and concentration of chemicals.
