Liquid polymer activation unit with improved hydration chamber

A polymer activation assembly comprising:

• a casing and first and second blocks securable within an interior chamber of said casing;
• a primary fluid channel having an inlet end and an outlet end is formed between said first and second blocks;
• said primary fluid channel is rectangular in cross-section and wider than it is deep along at least an activation portion extending between said inlet and outlet ends thereof;
• a secondary fluid channel having a secondary fluid channel inlet connecting to a nozzle section which intersects the activation portion of the primary fluid channel at an acute angle and which is wider than it is deep a primary fluid inlet is formed through a first end of said casing and extends in flow communication with said inlet end of said primary fluid channel;
• a mixed fluid outlet is formed through a second end of said casing and extends in flow communication with said outlet end of said primary fluid channel;
• and
• a secondary fluid inlet is formed through a side of said casing and extends in flow communication with said secondary fluid channel inlet.
